British Isles weather, January 2020

The 1st saw the development of a SW'ly flow across all areas during the day with MSL pressure above 1028 mb over SE England by the evening. There was an air frost across much of E Scotland and NE England before dawn, while many parts of England had mist or fog patches by dawn. There was some light rain and drizzle over parts of Ireland, S Wales and SW England while it was cloudy over many other areas of the British Isles. Later in the day it became windy over NW Britain. (Valentia 11.2C, Fyvie Castle 2.1C maximum, Redesdale Camp -6.7C minimum, Plymouth 3.0 mm, Leeming 5.3 h.)

A brisk SW'ly flow on the 2nd brought mainly mild conditions to the British Isles with areas of rain spreading SE'wards from W Scotland and W Ireland to N England and Cent S England by the evening. There was a ground frost in a few parts of England overnight although a mostly dull day followed in all areas, with some heavy falls of rain over high ground. (Shannon Airport 12.2C, Leek 7.4C maximum, Shobdon -0.4C minimum, Achnagart 39.6 mm, Leconfield 1.6 h.)

Rain cleared away towards the SE on the 3rd and pressure then rose from the W, reaching 1035 mb at Valentia by 2400 GMT. Minimum temperatures remained above 10C in and around Dorset overnight, but it gradually turned colder from the NW during the day behind cold fronts that gave the earlier rain. Away from parts of Kent, East Anglia, Jersey and N Scotland it was a sunny day at times. There were showers across parts of Scotland and Ireland during the day and evening, which fell as snow over N Scotland and some high ground in Scotland. (Swanage 11.0C, Dalwhinnie 4.3C maximum, Kielder Castle -0.2C minimum, Santon Downham 14.2 mm, Cork Airport 6.5 h.)

Pressure remained above 1036 mb in SW England on the 4th. After a mild night in many areas, a mild and fairly cloudy day followed in most places, although it was a cool day on Shetland (where there were overnight snow showers). There was rain across Scotland with lesser amounts over parts of Ireland, N England, Wales and W England while the best of any sunshine was to be found in parts of East Anglia, E England and Kent. (Achnagart 10.9C, Baltasound 4.9C maximum, Benson -0.7C minimum, Kinlochewe 23.6 mm, Leconfield 5.9 h.)

The British Isles lay under a warm sector on the 5th, with pressure close to 1036 mb on the Channel Islands. However, fronts gave some rain over N Scotland while there were widespread falls of light rain or drizzle elsewhere. It was especially mild over Scotland, N and W Ireland, although generally dull in all areas of the British Isles. (Dyce 12.5C, Okehampton 5.8C maximum, Wattisham 1.6C minimum, Achnagart 20.2 mm, Boulmer 2.2h.)

Cold fronts crossed most areas during the6th from the W, with falls of rain in most areas. It was a mainly cloudy day ahead of the frontal rain, with showers and sunny spells following the rain, especially across Ireland. Temperatures were near or above normal, with some northern areas being mild. (Lossiemouth 11.9C, Leek 6.9C maximum, Okehampton 4.2C minimum, Achnagart 25.2 mm, Cork Airport 5.7 h.)

Deep areas of low pressure close to Iceland on the 7th brought a windy day across the British Isles with several spells of frontal rain pushing E'wards during the day. Ahead of the rain there were a few bright intervals in NE Scotland and SE England; elsewhere it was a mainly cloudy day. There was fog on some hills. It became mild or very mild during the day. Traffic Scotland reported one overturned vehicle on the A1 between Thistly Cross and the Spot Roundabout, and another at Thorntonloch. Rail travel into and out of Edinburgh proved difficult during the evening rush hour after high winds caused an overhead line to come down at Haymarket Station. During the day, gusts reached 74 mph in Barra, with winds recorded at 70 mph in Inverbervie and 65 mph at The Forth Bridge. Strong winds caused delays on the Friarton, Erskine and Dornoch bridges and the Kessock and Skye bridges were closed to high sided vehicles. Almost all CalMac's 28 routes were affected by bad weather on Monday, and the company warned customers of possible further delays. Among other sailings cancelled were Ardmhor to Eriskay and the Oban, Coll and Tiree service. Cairngorm Mountain snowsports centre said it had experienced "extremely high winds" and the site would be closed all day. (Murlough 15.3C, St Bees Head 9.8C maximum, Shawbury 0.8C minimum, Cassley 60.0mm, Kinloss 2.6 h.)

Fronts moved away from E Britain during the 8th. England, Wales and S Ireland had a mild night with showers following the fronts in N and W areas. Ireland and S Britain became cloudy from the SW with rain across S areas of Britain and Ireland in the afternoon and evening. There were sunny spells over Scotland, but it was a dull day elsewhere. It was generally mild; however, temperatures were near or slightly below normal in some northern regions. (St James Park 12.3C, Aviemore 3.4C maximum, Aviemore 1.2C minimum, Cassley 21.6 mm, Dyce 5.1 h.)

On the 9th, apart from some rain in Shetland, the northern half of Scotland was mostly bright and cold after overnight frost. Rain and snow (with a covering of snow in places) over Northern Ireland, N England and S Scotland cleared away slowly E'wards, with some brighter spells following. It was quite cold. Further S, overnight rain and blustery winds cleared away to the E to leave a sunny interlude, but an area of low pressure to the S of Cornwall pushed a band of heavy rain quickly N'wards across S England, and then into S Wales and Cent England. It was mostly mild or very mild over southern Britain, especially in the SE and East Anglia - but was quite cool in Cent Ireland. (Writtle 14.1C, Balmoral -0.2C maximum, Kinbrace -2.9C minimum, Capel Curig 24.8 mm, Dundrennan 4.7 h.)

High pressure developed over S areas on the 10th while pressure fell in the N, resulting in increasingly windy conditions in N Britain as the day developed. Scotland and Northern Ireland had widespread air frost at first, while outbreaks of rain cleared away to the E across England by dawn. S and Cent England had a sunny day while cloud and rain spread across much of Scotland, Ireland and N England during the afternoon and evening. (Valentia 11.1C, Dalwhinnie 4.3C maximum, Braemar -7.9C minimum, Dunstaffnage 20.8 mm, Wittering 6.0 h.)

The 11th dawned after a generally mild night. There was heavy rain across N and W Scotland overnight and during the morning, before the rain area moved slowly SE'wards through Ireland and into N England and Wales by the evening. The rain fell as sleet and snow over high ground in some parts of Scotland. Showers followed the rain, with some thunder on Shetland later in the day. The day was generally cloudy, but temperatures reached 13C in parts of Wales and Ireland. It was a windy day in most areas. (Hawarden 13.9C, Dalwhinnie 6.9C maximum, Alice Holt Lodge 0.2C minimum, Achnagart 97.0mm, Weybourne 3.0 h.)

Rain across England and Wales cleared away SE'wards during the night and morning of the 12th, with showers following the rain, especially in N and W areas of the British Isles. Showers were thundery over Shetland during the early morning, while they turned to snow in places across N and W Scotland. Behind the rain there was an early air frost in parts of E Scotland while most places had sunny periods during the day. It turned cool once the early rain had passed. (Hurn 12.4C, Dalwhinnie 2.6C maximum, Aboyne -4.2C minimum, Cardiff Bute Park 19.2 mm, Cork Airport 6.6 h.)

The 13th saw a deepening area of low pressure moved NE'wards towards the NW of Ireland storm Brendan with the MSL pressure falling to 958 mb at South Uist Range by 1800 GMT. Parts of E England had some early sunshine ahead of frontal cloud and rain associated with this system which spread across all areas by the end of the day. Showers followed the rain with gusts up to 80 mph in the Hebrides. Storm Brendan brought severe weather across Scotland, leading to problems across the country with trees brought down and ferry sailings cancelled. Services on 10 of Caledonian MacBrayne's 28 ferry routes were cancelled for the day, with a further five routes being disrupted. Northlink Ferries also told passengers there would be disruption on services to Orkney and Shetland. All schools in the Uist and Barra area were closed and all bus services there were cancelled. The harbour at Fort William was swamped by floods in the evening. Northern Ireland Electricity said about 10,000 customers lost power; the worst affected areas were counties Down and Antrim. A number of flights and ferry sailings were also cancelled in Northern Ireland while part of the sea wall came down in Carrickfergus. Across the Republic of Ireland, more than 48,000 customers were left without power; the worst affected areas have been Cork, Kerry, Galway and Mayo. (Iver Water Works 11.7C, Dalwhinnie .4C maximum, Topcliffe 0.2C minimum, Achnagart 27.2 mm, Shoeburyness 3.6 h.)

On the 14th NW Scotland was showery, with snow, chiefly in the hills, and isolated thunder. Rain spread NE'wards elsewhere, persisting across Cent S and SE England in the evening in a warm sector. It was a warm day across Cent and S areas of England and Wales most places, away from NE Scotland were dull and cloudy. It became very windy with gusts over 60 mph in the evening in S England. Damage ranging from roofs being blown off to fallen trees was being cleared by emergency services after strong winds battered parts of the UK. A high street in Slough, Berkshire, was closed after a large section of a roof was blown off a block of flats. Meanwhile scaffolding from a 10-storey block in Orpington, London, collapsed in the evening due to gusts. In Southampton, port operator DP World urged trucks travelling with no booking to stay away due to a backlog of hundreds of lorries going through the port. 25 flood warnings and 165 flood alerts were issued by the Environment Agency, as coastal areas struggled with strong gusts, high tides and large waves. A gust of 78 mph was recorded on the Isle of Wight. (Weybourne 14.6C, Dalwhinnie 2.0C maximum, Dalwhinnie -0.1C minimum, Libanus 42.4 mm, Kirkwall 4.7 h.)

Mild and windy conditions gradually cleared from SE England early on the 15th, with further rain continuing here until the afternoon. Rain affected much of NW and Cent Scotland for much of the day; it was cloudy across N Scotland but there were spells of sunshine elsewhere. (Jersey Airport 11.2C, Dalwhinnie 3.9C maximum, Dalwhinnie 0.3C minimum, Achnagart 45.2mm, Ronaldsway 6.4 h.)

A S/SW'ly flow on the 16th brought mild weather to all areas but a depression pushing N'wards to the W of Ireland brought bands of frontal rain to most areas during the day. Showers followed the rain in W areas. A passenger was injured after a wave hit a coastal railway train, smashing windows; Great Western Railway's 10:57 GMT service from Exmouth to Paignton, in Devon, was damaged by "sea debris" as it travelled along the coast, near Dawlish. (Bude 13.1C, Dalwhinnie 6.4C maximum, Drumnadrochit 1.1C minimum, Tyndrum 26.8 mm, Manston 2.7 h.)

Rain cleared E'ward from SE areas of England early on the 17th, to be followed by spells of rain and showers in most areas during the day. After a mild night, temperatures rose little during the day with the best of any sunshine to be found over Ireland, mainland Scotland and W Wales. There were (unconfirmed) reports of a tornado winds in Barton-on-Sea and Ashley (Hampshire) with people being woken by howling winds and lashing rain in the early hours; homes were damaged, fencing was flattened and a 1.8 m wall was brought down. (Santon Downham 10.6C, Altnahinch Filters 2.8C maximum, Katesbridge -2.4C minimum, Achnagart 21.0 mm, Kinloss 5.5 h.)

Many areas of Wales, Ireland and W England had an air frost early on the 18th. A sunny day followed in all areas with some showers in W and N Scotland. High pressure developed across Ireland as the day developed reaching 1036 mb in SE Ireland by 1800 GMT. (Valentia 9.4C, Killylane 3.0C maximum, Katesbridge -5.5C minimum, Altnaharra 9.0 mm, East Malling 7.5h.)

MSL pressure continued to rise on the 19th - up to 1049 mb by 1800 GMT in SE Wales but only 1028 on N Shetland at this time. There was a widespread inland air frost over all parts of the British Isles with one or two freezing fog patches - which lingered through the day in parts of the Midlands. Many places, especially in the south, had a sunny day, but it became increasingly cloudy and breezy in northern regions, with a little rain on Shetland in particular. Daytime temperatures (away from any fog) rose above normal in many districts; frost returned to S and Cent England by mid-evening. (Stornoway 9.8C, Wellesbourne 1.5C maximum Topcliffe -6.8C minimum, Lerwick 4.2 mm, East Malling 8.1 h.)

On the 20th a sheet of altocumulus slowly cleared to the SE from southern Britain, and cloud also largely retreated from N Britain, so that most places (away from W and SW Scotland) became sunny. Away from Scotland, N and W Ireland there was an air frost; temperatures rose above normal in many places with some N areas becoming very mild during the day. Frost returned widely across England and Wales in the evening. MSL pressure peaked at 1050.5mb at Mumbles just after midnight early in the day, the highest in the British Isles since 16 January 1957, when Belmullet and Benbecula recorded 1050.9.mb. By 1800 GMT the centre of the anticyclone had MSL pressure of 1048 mb to the S of Ireland (Altnaharra 12.3C, Llysdinam 3.0C maximum, Yeovilton -4.8C minimum, Kinlochewe 2.6 mm, Cork Airport and Shobdon 7.6 h.)

By 1800 GMT on the 21st the high centre had declined to 1043 mb to the SW of Ireland - but most of Ireland, Wales and S England remained above 1040 mb. There was a widespread air frost across England and E Wales at first although at Belmullet the overnight minimum temperature was 9.0C. There was some frontal rain overnight in N Scotland with lesser falls elsewhere in Scotland during the day. There was widespread mist, and some fog, across England, Wales and areas of Ireland at first which persisted for much of the day in a few places; E Scotland and most parts of England then had a sunny day although it was dull elsewhere. Mist and fog patches returned across England, Wales and E Ireland in the evening. (Aboyne 12.9C, Yeovilton 0.4C maximum, Benson -5.3C minimum, Resallach 13.0 mm, East Malling 8.4 h.)

By 1800 GMT on the 22nd the high centre had fallen to 1039 mb just to the W of Ireland - but most of England, Wales and Ireland remained above 1036 mb. Away from N Scotland the day was mainly dry but widespread mist and fog at first was slow to clear in some areas and led to some drizzle in places. Air frost overnight was mainly confined to parts of E and S England while during the day sunshine was largely confined to S and E Scotland and to N England with dull conditions elsewhere. The mildest weather during the day was to be found across Scotland, particularly E Scotland. (Aboyne 14.5C, Wych Cross 5.3C maximum, Hurn -3.9C minimum, Resallach 8.0 mm, Morpeth Cockle Park 5.9 h.)

Pressure continued to fall during the 23rd with some rain from a cold front affecting N Scotland during the day. There was little overnight air frost but mist and fog were widespread around dawn over Ireland, Wales and England. This lingered all day in places, becoming thicker again in the evening and leading to some falls of light drizzle or snow the latter particularly over high ground in Wales, NW England and S Scotland. Away from the Channel Islands, E Scotland and parts of N England and N Wales the day was dull while daytime temperatures were above average except where the fog lingered. (Ravensworth 11.7C, Okehampton 3.4C maximum, Topcliffe -1.7C minimum, Resallach 12.0 mm, Guernsey Airport 7.3 h.)

Pressure remained high over S areas on the 24th but the day was mainly cloudy except in parts of N England, due partially to a weak front that lay across Scotland. Overnight there was little air frost, while some rain fell over W and N Scotland. There was mist or fog at dawn over many areas of Ireland, Wales and England which persisted all day in places. Temperatures rose only slightly during the day due to the extensive cloud, while some light drizzle and rain fell in places where mist and low cloud persisted. (Bridlington 11.4C, Tredegar Bryn Bach Park 3.3C maximum, Sennybridge -1.0C minimum, St Bees Head 3.8 mm, Leconfield 5.9 h.)

The 25th was another rather cloudy day in all areas. There was a little air frost in parts of NE England with some mist and fog patches in a few parts of England and Wales. Low cloud and mist led to some light rain and drizzle in places while light frontal rain fell later in W Ireland and W Scotland. (Isles of Scilly 10.9C, Pennerley 4.5C maximum, Leeming -0.5C minimum, Eskdalemuir 4.2 mm, Dyce 1.6 h.)

Cold fronts pushed E'wards across the British Isles on the 26th. Widespread cloud led to a mild night in many areas there was some sunshine early in the day in E England, and later across parts of Ireland as the fronts cleared. There was some heavy rain over high ground in W areas of Britain. Sleet fell in parts of W Ireland in the evening as the temperature fell sharply in places. (Exeter Airport 10.9C, Altnahinch Filters 4.4C maximum, Fyvie Castle 2.9C minimum, Achnagart 26.6 mm, Cork Airport and Connaught Airport 3.4 h.)

There was an air frost in E and S Scotland on the 27th. During the night and into the day rain spread from the W across all areas with some heavy falls in parts of S Wales and S England. In parts of Ireland, Scotland and N England the rain turned to snow while there was isolated thunder in some W districts of the UK. It was a dull day in W Scotland, W Ireland and S England with sunny periods elsewhere. In the evening the snow turned heavy across parts of Scotland after a cool day here. (Isles of Scilly 10.2C, Dalwhinnie 0.3C maximum, Aboyne -3.6C minimum, Tredegar Bryn Bach Park 22.8 mm, Boulmer and Morpeth Cockle Park 6.9h.)

There was snow overnight into the 28th in high ground in Scotland, Wales, N and SW England and the Peak District. A cool night led to an air frost in many areas of Scotland and N and W Ireland. During the day the snow turned to rain after some further falls in Ireland, Scotland, the Isle of Man and parts of W England. In many areas the skies cleared and there was widespread sunshine away from W Scotland. Drivers were stranded on the M74 for several hours overnight as heavy snow hit parts of Scotland; police said the M74 was shut between junctions 14 and 15 northbound for a time overnight, but was passable with care in the morning. (Isles of Scilly and St Helier 8.8C, Balmoral 1.8C maximum, Loch Glascarnoch -6.6C minimum, Dunstaffnage 20.6 mm, East Malling 6.4 h.)

A warm front crossed S areas of the British Isles during the 29th; there was an early air frost in NE Scotland while during the day it became much milder across S Scotland, Ireland, Wales and England. There was some snow in parts of Scotland during the day, but these falls became confined to N Scotland as the day developed. Overnight rain in W Scotland spread to other areas of Scotland during the day. Further S there were some lighter falls of rain and drizzle although in S England there were long spells of sunshine in many places before another area of cloud spread from the W in the evening. (Isles of Scilly 11.4C, Drumnadrochit 4.5C maximum, Fyvie Castle -3.2C minimum, Tulloch Bridge 41.6 mm, East Malling 7.2 h.)

It was mild overnight into the 30th from S Scotland S'wards. Areas of rain spread E'wards across Scotland (where it was also windy) overnight and during the day, with further rain affecting S England and S Wales for a time during the day. It was misty in parts of Ireland and also later in SW England once the rain cleared. Sunshine was largely confined to E Ireland but it was a mild day everywhere, with temperatures reaching 13C in parts of E Ireland and S England. (Exeter Airport 14.4C, Baltasound 7.4C maximum, Baltasound 0.4C minimum, Achnagart 36.4 mm, Cork Airport 2.9 h.)

It was a mild night everywhere into the 31st with overnight minimum temperatures above 9C in parts of S Ireland and S England. Low pressure centred to the W of Ireland drove fronts across the British Isles with rain affecting all areas, followed by showers further W although the rain tended to weaken as it moved across E areas of England. It was generally a dull day, but there was some sunshine over eastern Scotland and Northern Ireland, on a mild or very mild and blustery day. (Hawarden 14.2C, Baltasound 6.9C maximum, Lentran 1.9C minimum, Achnagart 35.2 mm, Dyce 2.5 h.)

British Isles weather, February 2020

There was a brisk W'ly flow in most areas during the 1st. After a mild night (overnight minimum temperatures remained above 10C in parts of S England), fronts brought spells of rain and showers S'wards across Scotland and N areas of England, Wales and Ireland. It was quite a sunny day in some parts of the Midlands, S Wales and S England with daytime temperatures reaching 11-12C in parts of S England and the Channel Islands. (Charlwood 13.9C, Lerwick 4.5C maximum, Baltasound 3.1C minimum, Kinlochewe 38.4 mm, Hawarden 6.6 h.)

Mainly inland areas of Scotland had an air frost on the 2nd; further S it was cloudier as frontal rain spread N'wards across Ireland, Wales and England introducing milder conditions in a S'ly airflow. There was snow on some high ground ahead of the rain. There was some sunshine in the Northern Isles and across N Ireland and N England, but most areas had a cloudy day with some showers. A further front across the English Channel led to some further rain in the Channel Islands. It was very much of the S half of the British Isles. (Charlwood 13.9C, Lentran 0.7C maximum, Aboyne -6.5C minimum, Lake Vyrnwy 28.6 mm, Lerwick 4.8 h.)

Low pressure close to N Scotland on the 3rd led to a showery and windy day across Scotland, Ireland, Wales and N England after a slight air frost in parts of NE Scotland. There was some snow over high ground in Scotland, N England and N Ireland especially later in the day. There was isolated thunder over S Scotland and NW England, especially in the evening. Away from S England, S Wales and N Scotland there were sunny periods; in S England there was a spell of more general rain for a time during the day. It was a mild day across parts of S England and the Channel Islands. (Heathrow 12.0C, Dalwhinnie 3.8C maximum, Aboyne -1.8C minimum, Achnagart 29.0 mm, Morpeth Cockle Park 7.2 h.)

As pressure rose to the SW of Ireland on the 4th a NW'ly surface flow dominated the weather for much of the day. By 1800 GMT pressure rose to 1036 mb in SW Ireland. Showers were widespread over Scotland, N Ireland and N England overnight but generally died out quickly during the day. Many areas had sunny spells during the day and the day was generally mild. (Carlisle 11.8C, Libanus 5.5C maximum, Dalwhinnie -0.4C minimum, Kinlochewe 10.4 mm, Eskdalemuir 6.5 h.)

High pressure led to an early air first in many areas into the 5th as far S as the Thames Valley; ground frost was widespread across the British Isles away from the coasts. The high pressure (centre 1039 mb over S Wales at 1200 GMT) also led to mist and fog in and around Cent England, which linger until late morning in places. There was some light rain at times in N Scotland, and before dawn in parts of W Ireland; however, away from Scotland most places were dry with sunny spells while daytime temperatures were above average everywhere. (St Helier 11.6C, Spadeadam 5.2C maximum, Aboyne -4.6C minimum, Dunstaffnage 2.8 mm, Shoeburyness 6.8 h.)

Ground frost was widespread across the British Isles on the 6th although air frost was largely confined to England and parts of E Ireland. With high pressure still prevailing there was overnight fog in N Ireland and across many areas of England and Wales. W Ireland and W and N Scotland were rather dull elsewhere it was a sunny day but with some light rain at times in the Northern Isles. (Aboyne 11.6C, Llysdinam 3.0C maximum, Topcliffe -4.9C minimum, Lerwick 2.0 mm, East Malling 9.2 h.)

During the 7th pressure steadily in all areas as a deepening area of low pressure developed to the SW of Iceland. There was an early air frost in E Scotland, England and E Wales with mist and fog around dawn in many areas of England. Freezing fog led to a few falls of snow grains in parts of Cent England. It was a sunny day in these frosty areas ahead of advancing frontal cloud and rain from the W which was falling over W Scotland, Wales and SW England by mid-evening. It became increasingly windy in the W and N and 7 mm of rain fell at Valentia in the 12 hours ending 1800 GMT. (Bridgefoot 12.2C, Dalwhinnie 4.3C maximum, Aboyne -6.6C minimum, Machrihanish 2.8 mm, Shap 7.4 h.)

Overnight into the 8th rain cleared to leave most places sunny for a time, with showers in the N. Further frontal rain spread across much of the British Isles during the day although SE England and East Anglia were still largely dry by mid-evening. Wind speeds increased in the N with gusts of up to 75mph in the most exposed regions. It was a mild day dur to the SW'ly flow. Several bridges were closed to high-sided vehicles due to the wind with the Erskine, Dornoch, Skye and Kessock Bridges among those affected. A 40 mph limit was also put in place on the Queensferry Crossing. (Cardiff Bute Park 12.1C, Dalwhinnie 4.2C maximum, Dalwhinnie 0.6C minimum, Tyndrum 39.0 mm, Kinloss 6.8 h.)

Storm Ciara brought wet and windy conditions to all areas on the 9th, overnight and during the day. The strongest gust recorded was 97 mph at the Needles although there were widespread gusts of 70 - 80 mph even in less exposed, inland sites, with a squall band of rain bringing some intense thundery downpours, and strong, squally winds. The highest rain totals were in parts of NW England and N Wales. Honister Pass, Cumbria recorded 177.0 mm in the 24 hours ending 1600 GMT. A gust of 83 mph was recorded at Aberdaron; many trees were brought down and there was widespread flooding. At 1200 GMT MSL pressure was down to 948.2 mb at Stornoway. England and S Wales had a generally cloudy day elsewhere, there were sunny periods once the main rain bands had cleared. There was thundery activity accompanied a double cold-frontal structure that crossed England and Wales during the day, with some also in showers behind the fronts over Cent and N regions. There was a particularly active storm in the Reading area shortly before midday. Flyaway trampolines caused rail chaos when Storm Ciara blew them on to tracks across England. All services were stopped between Bedford and Luton after a trampoline struck a train and reportedly became stuck in overhead wires. A 58-year-old man has died after a tree fell on his car in Hampshire during Storm Ciara between Winchester and Micheldever on the A33 just before 1600 GMT. Strong winds forced a flight at Heathrow to abort its landing seconds after touching down on the runway; a video posted on social media showed a British Airways plane struggling to land. In the UK as a whole about 118,000 people were without power as of 1600 GMT. Dozens of people had to leave their homes in Redvales, Radcliffe, Greater Manchester after the nearby River Irwell burst its banks. In Perth, three people were injured after part of a pub roof collapsed after being hit by a chimney breast. P&O's North Sea ferry, the Pride of Hull, docked at 1600 GMT in Hull from Rotterdam after an eight-hour delay; the ship had to ride out the stormy condition in the North Sea. All P&O services between Dover and Calais were suspended. In Ireland a number of roads were closed due to localised flooding. Blades from the top of a historic windmill at Burgh Le Marsh, Lincolnshire, were torn off by 70 mph winds. Residents had to be evacuated after this huge crane collapsed through the roof of an unoccupied block of flats on a building site in Stanmore, Harrow. (Donna Nook 14.8C, Lerwick 4.2C maximum, Tulloch Bridge 0.0C minimum, Capel Curig 122.6 mm, Leuchars 4.7 h.)

On the 10th disruption continued as the after-effects of Storm Ciara were felt across the British Isles, following widespread flooding and severe gales. There was a brisk surface flow from the W during the day, with spells of showers in all areas, accompanied by hail and thunder. Snow fell over high ground in Scotland, and as far S as high ground in S Ireland and Cornwall; in the wind there were blizzard conditions in northern hills. More than 20,000 homes spent the night without power, while flood warnings remained in place across the country. Flooding and debris continue to cause problems for rail passengers. Lines disrupted included the West Coast Main Line, which had no trains running north of Preston because of flooding at Carlisle. Traffic Scotland said snow and wind were causing difficult driving conditions on the road network. (Isles of Scilly 10.7C, Salsburgh 0.8C maximum, Dalwhinnie -0.7C minimum, Gt Cumbrae Millport 25.6 mm, Dyce 7.2 h.)

The brisk W'ly flow continued across all areas on the 11th. There was an air frost in parts of Cent Scotland and the day was very showery, especially over Ireland and Scotland - but also in Wales and W and Cent England. There were falls of hail and snow (mainly over Scotland and Ireland) and also thunder. It was a cold day over N England and N Ireland N'wards, while S areas of England and Ireland had sunny spells, especially in SE England. A dog-walker in his 60s died after a tree branch fell during stormy weather in Liverpool in the morning. More than 400 people in Cumbria were warned not to drink, wash or cook with tap water after a main was damaged by the storm. Travel disruption continued in Wales, with some main roads blocked and train services suspended. Cars were trapped in some areas after heavy snow fell on Monday and into today. The Queensferry Crossing that connects Edinburgh and Fife was closed for the first time since it opened in 2017, after ice and snow fell from cables on to the carriageway. (Shoreham 8.8C, Spadeadam 0.8C maximum, Altnahinch Filters -0.9C minimum, Cassley 30.8 mm, East Malling 8.7 h.)

A brisk flow from the W on the 12th was accompanied by showery conditions across Scotland with more persistent frontal rain over N Scotland. The showery conditions also affected Ireland and parts of Wales and W England - with more general frontal rain moving across Ireland, S Wales and S England in the afternoon and evening. The day followed a generally cold night with Scotland then having a cold day although there were widespread sunny spells from S Scotland S'wards. In the cold conditions many showers fell as snow over Scotland and N Ireland, with a few showers at times over parts of N England, Wales and Eire. (Hurn and Isles of Scilly 9.7C, Drumalbin 1.7C maximum, Killylane -1.1C minimum, Cassley 39.2 mm, Wattisham 8.3 h.)

There was a sharp frost in N and E Scotland overnight into the 13th with air frost also in inland areas of W and S Scotland, and in parts of N England. Rain moved NE'wards across England, Wales, Northern Ireland and into Scotland, with snow for a time in the more N'ly areas and sleet as far S as high ground in the Midlands and SW England. The rain (associated with an area of low pressure that crossed E'wards over the British Isles centre 989 mb at 1200 GMT over NE England) moved into the North Sea later in the morning but a further area of rain crossed S areas of England. Sunny spells followed the earlier area of rain in most places, interspersed with showers and isolated thunder in SW and Cent S England in the rain areas. A man suffered head injuries when a possible tornado blew large stones through the roof of a flat on the Isle of Wight, shortly before 0430 GMT. A massive lightning strike also resulted in power failure in some parts of the island. N and Cent Scotland were cold, but temperatures rose above 10C in S areas of England, Wales and Ireland. (Hurn 11.6C, Kinbrace 1.1C maximum, Braemar -10.2C minimum, Banagher Caugh Hill 35.6 mm, Cork Airport and Shannon Airport 5.9 h.)

A deep area of low pressure SW of Ireland pushed areas of rain SE'wards across all areas on the 14th, with some falls of snow or sleet over high ground in Scotland. Ahead of the rain much of Scotland and many parts of N and Cent England had an overnight air frost with some mist and fog patches in Cent England by dawn. Some showers followed the rain and it became mild but increasingly windy. (Murlough 12.7C, Aviemore 5.1C maximum, Loch Glascarnoch -9.1C minimum, Braemar 20.6 mm, East Malling 6.0 h.)

Storm Dennis began to affect the British Isles on the 15th as an area of low pressure S of Iceland intensified to a central pressure of 922 mb by 1800 GMT. After a mild night in S England, S Wales and S Ireland the day was mainly wet and windy with the heaviest rain mostly over hight ground and from N England and Cent Ireland N'wards. Between midnight on the morning of Saturday 15 February and 10:00 on Monday 17 February a Natural Resources Wales site at Crai Resr in Powys. south Wales, recorded 157.6mm of rainfall. There was thunder in the early evening in the Tees Estuary region. There were gusts of up to about 70 mph in the most exposed areas with 91 mph reported at 1800 GMT at Aberdaron. It was a day with extensive cloud cover. (Wellesbourne 13.9C, Dalwhinnie 5.8C maximum, Kielder Castle -0.4C minimum, Shap 63.2 mm, Thomastown 0.6 h.)

As the low pressure centre S of Iceland moved slowly E'wards on the 16th, MSL pressure fell to 957.8 mb at Stornoway by 1800 GMT. Widespread cloud and rain meant a generally mild night (for example the temperature was 14.4C at 0300 GMT at Weybourne). The large rain area then slowly cleared to the SE, after giving several hours of heavy rain to much of England and Wales. Rather brighter, showery weather followed although much of S and E England remained dull. Some of the showers were heavy, with hail, and thunder locally mainly in the N and W; the showers merged into longer spells of heavy rain over Scotland. Winds were much lighter for some time behind the cold front, but increased again as the showery airflow became established, with some particularly strong gusts (84 mph at Mumbles) as a showery trough crossed southern Britain during the late afternoon and evening. Over the 24 hours, gusts of up to about 70 mph were quite common in the more exposed areas. N and Cent Scotland saw some of the rain and showers turning to snow in colder air. There was flooding over various parts of England, Wales and S Scotland. Flooding and landslides affected swathes of south Wales in what police declared to be "a major incident"; more than 20,000 properties across the region suffered power cuts during the storm. A record number of flood warnings and alerts were issued for England on Sunday, according to the Environment Agency, reaching a combined total of 624 by Sunday night. Dramatic video footage emerged of a landslide tearing down a mountain in Tylorstown, Rhondda Cynon Taf, south Wales, on Sunday morning. A major incident was also declared after flooding at properties in Lowdham in Nottinghamshire. Properties were also flooded in Tenbury Wells, Worcestershire while in Scotland the Forth and Tay road bridges were been closed to all traffic. Across the UK road, rail and air travellers also face disruption. About 170 flights were cancelled on Sunday morning, affecting at least 25,000 passengers. Storm Dennis caused disruption for 19 train companies, according to National Rail, with routes suspended across south Wales and in parts of England and Scotland. Highways England said strong winds had closed part of the M48 Severn Bridge eastbound, while flooding closed part of the M54 and A-roads in Lincolnshire, Herefordshire, Derbyshire, Nottinghamshire and Gloucestershire. Police said a man had been rescued near Eastham Bridge over the River Teme near Tenbury Wells, Worcestershire, at 1130 GMT but a woman was still missing. (St Helier 13.8C, Dalwhinnie 3.4C maximum, Dalwhinnie -0.2C minimum, Tredegar Bryn Bach Park 62.6 mm, Dyce 6.7 h.)

Pressure continued to fall early in the day across Scotland on the 17th, down to 953.7 mb at Baltasound by 0600 GMT as the centre of storm Dennis passed just to the N of Shetland. A strong W'ly flow continued during the day, which was bright at times, with showers which were particularly frequent and heavy in W Scotland. Hail fell in places, and there was isolated thunder, mainly in then and W, but also in the vicinity of the Thames Estuary in the morning. Despite th wind, it was a mild day with sunny periods in most areas. Storm Dennis has left more than 400 properties flooded, with about 270 of those in the West Midlands, the Environment Agency said. Among the worst affected areas are Herefordshire, Worcestershire and Shropshire, where major incidents were declared. Worcestershire has borne the brunt of the flooding with about 200 homes affected. West Mercia Police said residents in Upton upon Severn and Uckinghall in Worcestershire were being advised to evacuate, with water levels expected to rise on Monday evening. Emergency evacuations were also under way in Hereford, where the River Wye reached its highest level on record. In Shropshire, 16 roads have been closed due to flooding. Residents of park homes on the River Stour near Christchurch, Dorset, were also told to leave as water levels continue to rise. (Wisley 11.7C, Dalwhinnie 5.3C maximum, Dalwhinnie 1.0C minimum, Tyndrum 44.8 mm, Dyce 8.8 h.)

A brisk W'ly flow on the 18th led to a day with sunshine and showers with the best of sunshine tending to be found in E areas of the UK. The showers turned to snow over N Scotland, and also for a time over high ground in parts of N England and Wales. There was isolated thunder, mainly in some N and W areas, although in the evening thunder was also heard over SE London and S Essex. It was milder than normal in S areas. Homes along the River Severn in Shropshire were evacuated, amid fears that flood barriers could be breached as waters moved downstream after recent heavy rains over higher ground. Houses and a pub near Ironbridge were submerged by rising waters and the water pressure cracked road surfaces. Around the UK, more than 150 flood warnings remained in place, including six severe - or "danger to life" - warnings. The River Wye at Monmouth, in Wales, has reached its highest recorded level, while the worst affected areas are S Wales, Herefordshire, Worcestershire and Shropshire, where major incidents have been declared. (Heathrow 11.4C, Aviemore 2.3C maximum, Dalwhinnie 0.2C minimum, Kinlochewe 24.8 mm, Dyce 6.4 h.)

A low pressure system over the NE Atlantic pushed fronts across the British Isles on the 19th, giving spells of rain (heavy over parts of Wales, Ireland and NW England) preceded by snow over high ground from N Scotland to the Midlands. After a cold start to the day it turned milder in all areas as the British Isles lay under a warm sector by early evening. E areas of the UK were sunny ahead of the warm front, while further rain fell over Scotland, N England and Ireland in the evening. (Isles of Scilly 11.1C, Dalwhinnie 5.4C maximum, Baltasound -1.8C minimum, Capel Curig 36.2 mm, Weybourne 5.8 h.)

A cold front crossed all areas from the W on the 20th in a W'ly flow, bringing a spell of rain - followed by showers (the latter mainly in the W half of the British Isles) and noticeably colder air in its wake. The rain was very heavy over some areas of high ground in Wales and Scotland and continued to cause flooding in places.. These showers fell as sleet or snow over high ground and across N and W Scotland and Northern Ireland. There were also isolated reports of thunder in this showery airstream, which was blustery. Away from East Anglia and SE England, it was a sunny day once the rain had cleared. (Bridlington 12.2C, Dalwhinnie 2.8C maximum, Loch Glascarnoch 0.2C minimum, Shap 50.4 mm, Cork Airport 7.2 h.)

The 21st was a day with brisk W'ly winds. The winds and widespread cloud prevented an air frost at low levels, and by dawn there was widespread rain across W Scotland and N Ireland. The rain spread across much of Scotland, Ireland W England and Wales by the evening and only parts of E Ireland and E Scotland saw any sunshine during the day. The rain was heavy in parts of NW England and W Scotland. Temperatures generally were near or rather above normal. Flooding continued to affect parts of the country - mostly the typical flood plain regions. (Fyvie Castle 13.5C, Tredegar Bryn Bach Park 6.8C maximum, Dalwhinnie 0.2C minimum, Tyndrum 61.6 mm, Dyce 5.5 h.)

Bands of rain crossed all areas during the 22nd although falls were slight over East Anglia and SE England. It was a cool night over N and Cent Scotland, and colder air spread to all areas after the rain. Across Scotland the rain fell as snow in the N and E, and there were also some wintry falls over NW England and N Wales. Much of the UK had sunny spells later in the day, but it remained dull over most of Ireland. By mid-evening there was a frost in parts of Cent Scotland, but temperatures were around 10C in S England. It was generally windy, with a few gusts of 60-70mph in the most exposed areas. (Heathrow 14.3C, Braemar 1.9C maximum, Braemar -0.6C minimum, Lake Vyrnwy 47.4 mm, Dyce 7.0 h.)

A wave depression moved E'wards across Cent England during the 23rd, spreading rain - heavy over Wales and NW England before dawn - across S Scotland, Ireland, Wales and England this was followed by showers, especially in W areas. These showers fell as hail and snow in parts of N Scotland. Overnight minimum temperatures were above 8C across much of S England, and temperature then rose to 12C and above across S and Cent England and Wales, and in parts S Ireland. Away from the S coast of England, the Channel Islands and S Ireland (where there was further rain in the afternoon and evening) there were sunny spells once the early rain had cleared. (East Malling 16.0C, Dalwhinnie 3.0C maximum, Fyvie Castle -1.4 C, Lake Vyrnwy 44.6 mm, Leuchars 8.2 h.)

On the 24th an area of rain crossed the British Isles from the SW (as a depression crossed from Ireland NE'wards towards the North Sea), and turned to snow over many parts of Scotland, N England and N Ireland. Rain and snow persisted over N Scotland, but it cleared away to the SE elsewhere. Away from Ireland, N Wales and N England it was a generally cloudy day. It was rather cold over Scotland (locally very cold over snow cover); there was a marked temperature contrast (up to 10 degC in maxima) between much of N England and S Scotland. (Coningsby 14.1C, Braemar 0.3C maximum, Dalwhinnie -3.3C minimum, Capel Curig 54.2 mm, Cork Airport 4.2 h.)

The 25th dawned after a mainly cool night with an air frost in Cent Scotland. After a showery night mainly in Scotland and Ireland, showers became more widespread due to a W'ly flow. These fell as snow in places as far S as Cent Ireland, S Wales, the Midlands and Norfolk with some hail in places, and also isolated thunder (including over London City Airport around 1715 GMT). It was mostly quite cold in the N, with near-normal temperatures in the S where it was breezy. There were widespread sunny periods between the showers. (St Helier 10.7C, Dalwhinnie 2.1C maximum, Braemar -6.2C minimum, Rochdale 20 mm, Dyce 6.9 h.)

The winds eased slightly on the 26th, which was another showery day. These showers mainly fell in the W half of the British Isles, with long sunny spells in parts of E Ireland, E England and E Scotland. Hail and snow fell in places, including in parts of SW England before dawn; however, most of the snow fell over Scotland, with lesser falls over N Ireland and over some high ground in the Midlands, Wales and N England. Temperatures were near or rather below normal, and it was blustery near the showers. Rain spread into SW Ireland, S Wales and SW England in the evening. Residents have had to evacuate their homes as flood waters rose above defensive barriers in Worcestershire. This happened as two severe flood warnings remained in place in Shropshire with the River Severn at risk of breaching defences in Ironbridge. Ironbridge, Shrewsbury and Worcester were among the areas at risk of flooding along the River Severn. Rescue operations were under way to get people from their homes in Bewdley; Hereford and Worcester Fire and Rescue Service went house-to-house in the area with a dingy, helping people from their homes. The flood barriers in Bewdley are temporary barriers, they were overtopped last night at about 1900 GMT, the water turning from a trickle into a torrent. Train lines remain closed out of Shrewsbury railway station due to high water levels under the Severn Railway Bridge and trains were only running out of the station towards Crewe and Chester. Roads around the Ironbridge Gorge were also closed to stop people driving in floodwater, Telford and Wrekin Council said. (St Helier 9.6C, Dalwhinnie 1.6C maximum, Braemar -5.1C minimum, Leek 13 mm, Boulmer 9.4 h.)

Much of Scotland, N Ireland and areas of N England had an air frost on the 27th. There were further wintry showers in the north. An area of rain, and some snow, crossed much of England and Wales overnight. The snow fell especially over high ground, but many places in the southeast had a few minutes of light sleet or snow (the first of the winter for many) at the back edge of the rain area in mid-morning. Away from N Scotland a mainly sunny day ensued. (Guernsey Airport 10.2C, Loch Glascarnoch 2.5C maximum, Drumnadrochit -4.0C minimum, Wych Cross 15 mm, Morpeth 9.7 h.)

Much of England (as far S as the S coast) had an air frost into the 28th. There were spells of rain and showers overnight in Ireland, Wales and W Scotland with more general rain spreading across all areas during the day. Falls were particularly heavy across Wales, helping to deepen floodwaters further in many areas affected by the Wye and Severn. There was snow in some N areas of Scotland and in places to the E of the Welsh hills. However, temperatures rose and, away from N and Cent Scotland, it was quite mild by mid-evening. Away from parts of Ireland it was a dull day. Murlough 13.1C, Dalwhinnie 2.2C maximum, Benson -3.5C minimum, Cardiff 51 mm, Magilligan 1.9 h.)

Rain spread across most of the British Isles overnight into the 29th, giving way (except in the far north) to a generally showery day with some sunshine. There was hail in many of the showers, snow chiefly in the north, and isolated thunder. A longer period of rain, with hill snow in the north, moved E'wards during the afternoon and evening, although S Britain was not affected. It was windy and, after a very mild night in Cent and S England, temperatures were near or rather below normal. Flooding continued to affect large areas of Wales, the West Country and N England. Heathrow 9.8C, Dalwhinnie 2.1C maximum, Balmoral -1.0C minimum, Eskdalemuir 40 mm, Camborne 6.2 h.)

British Isles weather, March 2020

Low pressure to the N of Scotland on the 1st led to a breezy day; there was a slight air frost at first in NW Scotland. Many areas had showers overnight and during the day, while across Scotland there was more general rain that moved N'wards. It was a sunny day across much of England, Wales and S Ireland before another area of rain moved into SW England and S Wales in the evening. Over high ground in N Scotland rain turned to snow in places. (Kew Gardens 11.1C, Braemar 3.2C maximum, Loch Glascarnoch -0.3C minimum, Kielder Castle 25.2 mm, Manston 9.0 h.)

Rain spread E'wards across S England and into East Anglia before dawn on the 2nd. This fell as sleet and snow in parts of S Wales at first and there was also some overnight sleet and snow in parts of N Scotland where there were overnight showers. Away from S England there was a widespread inland air frost. There were showers during the day across Ireland, N England and Scotland in particular which were wintry in places. Most areas had sunny spells during the day, especially over England and Wales. (St James Park 10.9C, Spadeadam 3.7C maximum, Coningsby -3.1C minimum, Kinlochewe 18.4 mm, Aberdaron 9.2 h.)

Low pressure (centred over NW Scotland at 979 mb at 0000 GMT on the 3rd) remained close to N Scotland, and led to a W'ly flow during the day. Showery rain affected most areas at times, especially over N and E areas. There was a slight air frost in some E areas of England and Scotland, and as temperatures fell again in the evening there was some snow in parts of Scotland. There were sunny spells in most areas during the day. (Cardiff Bute Park 11.7C, Leek 5.6C maximum, Shoreham -2.5C minimum, Loch Glascarnoch 11.2 mm, Aberdaron 9.1 h.)

Many areas of N Ireland, Scotland, N and E England had an air frost on the 4th but there was some rain over S Ireland, S Wales and SW England by dawn. This rain spread E'wards across S England, much of the Midlands, East Anglia and Wales, followed by drier conditions. Ahead of the rain there was some sunshine, particularly across Scotland while much of Ireland had a very sunny day. There were some showers in W Scotland and daytime temperatures were mostly near or rather below normal. (Plymouth 11.8C, Lake Vyrnwy 2.7C maximum, Aboyne -4.7C minimum, Plymouth 10.4 mm, Aldergrove 9.7 h.)

An area of low pressure moved E'wards across the Channel Islands on the 5th, leading to a rather wet day in S areas of Britain and the Channel Islands. Many areas of Scotland, N England and N and Cent Ireland had an overnight air frost followed by a mainly dry day with sunny spells. There were some showers across NW Scotland, while further frontal rain pushed across many areas of Ireland in the afternoon and evening. It gradually became drier from the W across S England after prolonged rainfall in places. In places, some of this rain was reported falling as sleet over high ground. (Jersey St Helier 11.5C, Okehampton 3.2C maximum, Katesbridge -5.9C minimum, Herstmonceux 36.2 mm, Leeming 8.9 h.)

Many areas, except across much of Ireland and W Scotland, had an air frost into the 6th. Low pressure to the W of the British Isles gave some rain across Ireland and in W Britain overnight. During the day rain and showers in these W areas diminished; there were spells of sunshine in most W areas during the day while in the E there was prolonged sunshine in many places. (Nantwich 11.2C, Tulloch Bridge 3.7C maximum, Altnaharra -7.3C minimum, Culdrose 7.4 mm, Morecambe 9.6 h.)

A warm front pushed NE'wards across all areas on the 7th, preceded in some E areas of the UK by an overnight air frost. The front gave little rain away from Scotland; much of this rain was associated with a cold front that slowly spread SE'wards across Scotland and Ireland in the evening. It was mild during the day in all areas, but rather cloudy away from some E parts of the UK. Parts of NW Scotland were very wet during the day. River levels in a flood-hit Shropshire town have halved from what they were last week, the Environment Agency said. Flood barriers which buckled in Ironbridge, causing numerous evacuations, were also being removed. The Association of British Insurers said an average of £32,000 will be paid out per household for flood claims after storms Dennis and Ciara. (Kinloss 13.9C, Eskdalemuir 7.3C maximum, Santon Downham -3.1C minimum, Achnagart 75.0 mm, Shoeburyness 3.9 h.)

Overnight and during the early morning of the 8th a cold front cleared away E'wards over the British Isles, giving some rain to most areas. Some places in NW Ireland, behind the front, had a touch of ground frost by dawn. A showery day followed, particularly over Ireland and W areas of the UK. There were sunny spells in most areas, resulting in a mild day in many places. (Heathrow 14.3C, Dalwhinnie 5.0C maximum, Dalwhinnie 1.7C minimum, Capel Curig 35.4 mm, Lyneham 7.1 h.)

Overnight into the 9th there was some rain in parts of Ireland and Scotland, before an area of more widespread frontal rain spread into W Ireland by dawn; early air frost was largely confined to parts of E Scotland. This spread E'wards across all areas of the British Isles by the evening, with the best of any sunshine being in the E extremities of the UK. Wind speeds increased during the day, and by early evening MSL pressure had fallen to 984 mb in the Western Isles. By 2100 GMT temperatures had risen to 11C across much of Ireland under a warm sector. 24 mm of rain fell in the 12 hours ending 1800 GMT at Shannon Airport. (Murlough 12.3C, Dalwhinnie 5.4C maximum, Aboyne -3.1C minimum, Derrylin Cornahoule 27.6 mm, Kirkwall 6.5 h.)

The 10th was a rather cloudy day, especially across S and Cent parts of England and Wales. There was widespread frontal ran overnight, which was heavy and persistent across parts of Wales and the Midlands. Further rain fell here, and across NW England during the day, before clearing away E'wards and being followed by showers. Despite the breezy conditions, it was a mild day everywhere. Two people were rescued from cars after heavy rain brought flooding to parts of Wales. The River Ely burst its banks at Peterston-super-Ely in Vale of Glamorgan, where members of the public rescued someone from their car, while there was a second car rescue on the A458 in Cyfronydd, Powys. Rail services were disrupted, with trains between Cardiff and Bridgend cancelled due to flooding and bus replacement services operating. (Monks Wood 16.5C, Loch Glascarnoch 6.7C maximum, Aboyne -0.9C minimum, Sennybridge 26.0 mm, Dyce 5.8 h.)

It was a mild night across S England into the 11th with overnight minimum temperatures above 10C, before a cold front cleared away SE'wards. There were some showers overnight across Scotland and Ireland, that also spread into Wales and N England during the day. It was cooler in this showery airflow, and the showers turned wintry across parts of Scotland, Ireland and N England into the evening. The best of the sunshine was to be found across East Anglia and in other E areas of the UK. Flooding closed railways lines and roads in parts of Wales, with a number of flood warnings remaining in place. All lines between Llandudno Junction in Conwy and Blaenau Ffestiniog in Gwynedd were blocked. In Powys, the A458 between Cyfronydd and Llanfair Caereinion was closed along with the A490 between Cilcewydd and Coed-y-Dinas past Mid Wales Airport. (Heathrow 15.4C, Loch Glascarnoch 4.0C maximum, Dyce -0.9C minimum, Shap 23.2 mm, Dyce 8.5 h.)

The 12th was a cold, showery and blustery day as an area of low pressure pushed E'wards across Scotland (with two centres of 984 mb and 985 mb close to the Western Isles at 1200 GMT). By dawn wintry showers had fallen over parts of W Scotland, Ireland, N England and Wales and these continued over high ground in Scotland until the evening. Rain and showers were widespread overnight but during the day much of E England was generally dry with the best of the sunshine being found here. Most other areas of England and Wales also had some long, sunny spells. (Coningsby 12.0C, Loch Glascarnoch 2.0C maximum, Dalwhinnie -1.5C minimum, Tulloch Bridge 29.4 mm, Shoeburyness 9.7 h.)

A weak ridge of high pressure on the 13th led to sunny spells in the E and N of the British Isles, but it was cloudier elsewhere due to low pressure centred just W of Ireland. Parts of N Ireland and Scotland had a slight air frost at first, while many areas (away from Cent, E and S England) had some overnight showers. During the day there were a few showers in the NW, and a narrow band of showers drifted NE'wards over N Wales, the Midlands and N England. An area of frontal rain associated with the low pressure moved into S Ireland, Wales and S England. Many places were rather cold, but it was milder in the S. (Pershore College 13.4C, Dalwhinnie 3.4C maximum, Katesbridge -2.4C minimum, Camborne 11.0 mm, Loch Glascarnoch 8.6 h.)

The 14th was a mainly cloudy day as frontal rain and showers spread E'wards across many areas. S and Cent England turned generally drier as the day developed. After little overnight air frost across the UK, temperatures rose to 12C in parts of S and Cent England, although over high ground in Scotland the rain turned to snow in places. Into the evening pressure fell and winds increased over Ireland and Scotland. (Northolt 13.9C, Dalwhinnie 5.2C maximum, Kinlochewe -1.2C minimum, Capel Curig 23.2 mm, Altnaharra 3.2 h.)

An area of low pressure moved across Scotland on the 15th (centre 982 mb over the Western Isles at 0600 GMT), driving a narrowing belt of rain SE'wards, reaching SE England late in the day. Showers and sunshine followed this rain with temperatures reaching 10C in places as far N as E Scotland. The best of the sunshine was across Ireland as a ridge of high pressure developed from the SW. (Gosport Fleetlands 13.0C, Blencathra 6.3C maximum, Cassley 1.1C minimum, Capel Curig 38.0 mm, Shannon Airport 8.5 h.)

A ridge of high pressure into the 16th led to an air frost in many areas of Scotland, and in some inland areas of Ireland, Wales and England. A sunny day followed in much of S England and the Channel Islands. However, by dawn a frontal system had produced cloudy skies across W Scotland and this cloud then spread E'wards, with rain falling over Ireland and Scotland, and in parts of N England, by mid-evening. (Frittenden 13.8C, Dalwhinnie 6.0C maximum, Aboyne -7.6C minimum, Achnagart 22.8 mm, Guernsey Airport 11.0 h.)

A front moved S'wards on the 17th across N areas, becoming almost stationary across Cent areas of the British Isles. Much of S England, East Anglia and the Midlands remained largely dry; it was sunny in the Channel Islands but rather cloudy elsewhere. Other areas remained rather cloudy with some rain and showers falls were especially heavy over parts of S Scotland, and in N and W Ireland. It was quite breezy over parts of N Scotland. S and Cent areas of Ireland, Wales and England were quite mild. (Santon Downham 15.9C, Resallach 5.9C maximum, Alice Holt Lodge 0.4C minimum, Eskdalemuir 27.2 mm, Jersey Airport 10.2 h.)

A slow-moving cold front on the 18th marked the boundary of cool air to the N of, and milder air to the S of, a line Cardiff-Lincoln. Breezy conditions in the N help prevent an air frost in most places, but there were some showers here that turned wintry over the mountains of Scotland. It was cloudy over most of England and Wales, although parts of the SE had sunny spells. Rain moved slowly across, chiefly, Wales and the Midlands. It was locally very cold in some of the wetter areas. (St James Park 16.0C, Pennerley 4.7C maximum, Fyvie Castle -0.5C minimum, Capel Curig 21.6 mm, Jersey Airport 11.7 h.)

On the 19th Scotland, Ireland and much of N England had sunny spells, with a few showers - chiefly in NW parts of Scotland and Ireland. After overnight frost, temperatures mostly rose to near normal although some of the showers were wintry early and late in the day over N Scotland. Wales and remaining areas of England were dull and cold with spells of rain or drizzle, especially from S Wales to the Midlands. Temperatures were higher towards the south coast - but it was very cold, and often foggy, over the moors of SW England (around 4-5C). (St Helier 13.9C, Liscombe 3.8C maximum, Katesbridge -5.0C minimum, Mumbles Head 9.6 mm, Prestwick 9.0 h.)

High pressure to the N on the 20th (centred 1038 mb over Shetland at 1800 GMT) drew an E'ly flow across all areas, leading to a rather cool day. Ireland, Scotland and N England had a widespread air frost followed by a sunny day in many areas. Frontal cloud and some light rain in S England and along the English Channel coast led to a dull, cool day here with temperatures below 9C in places. (Crosby 11.7C, Baltasound 4.3C maximum, Braemar -7.5C minimum, Bedford 1.8 mm, Tiree and Glasgow 11.5 h.)

A E'ly flow continued across the British Isles on the 21st. A few areas of NE Scotland and NE England had an air frost and there was some light snow over high ground in E Scotland and N England as showers moved inland. Ireland and some W areas of UK had a cloudy day as did the E coast of Scotland. There was rain across W Ireland 4 mm fell during 0600-1800 GMT at Shannon Airport. It was a cool day in W Ireland and in other dull areas. It was very sunny in SE England and East Anglia, and the dew point fell to -10C in places here in the afternoon as very dry air affected the surface for a time. (Otterbourne Water Works 12.7C, Loch Glascarnoch 4.9C maximum, Aviemore -6.7C minimum, Kielder Castle 1.4 mm, East Malling 11.4 h.)

High pressure over Scandinavia continued to maintain an E'ly flow in E areas of the U on the 22nd while there was overnight rain in W Ireland and Scotland that had mainly cleared from NE Scotland by mid-morning. There was an early air frost in S Scotland, N England, N Wales and the N Midlands then a very sunny day in all areas followed except in parts of N Scotland. The Channel Islands had a grey, chilly day with showers in the evening. Temperatures then widely dipped in the evening. 9 mm of rain fell at Valentia in the 12 hours ending 0600 GMT. (Porthmadog 14.3C, Fylingdales 6.5C maximum, Eskdalemuir -3.5C minimum, South Uist 2.8 mm, East Malling 12.2 h (suspiciously high.))

Pressure remained generally high on the 23rd although frontal cloud and rain, initially over W Ireland before dawn, spread across W Ireland, W and N Scotland by late evening. There were some heavy falls in W Scotland. SE Scotland, N Wales and much of N and Cent as far SE as the Home Counties had an air frost at first, as did parts of E Ireland. Away from the W and N Ireland, and W and N and Cent Scotland, it was a sunny day under almost clear skies especially in E and S England with temperatures reaching 14C in parts of mid-Wales. (Trawsgoed 15.7C, Baltasound 7.2C maximum, Topcliffe -6.0C minimum, Harris Quidnish 20.0 mm, East Malling 12.3 h (suspiciously high.))

While pressure remained high to the E on the 24th, frontal cloud and rain affected W Ireland and W and N Scotland. This rain was heavy in W Scotland, as it slowly moved N'wards and turned wintry over high ground in places. There was an air frost under clear skies in inland areas of England, but a mild day followed away from the coast over much of England and Wales with 15C being widely reached. Much of S and E England were especially sunny and temperatures only fell slowly across N England under cloudy skies in the evening. There were some very low dew points in places under the high pressure. Sligachan (an Isle of Skye sea-level site) recorded 219 mm in 48 hours 23rd-24th. (Rhyl 19.4C, Tyndrum 8.5C maximum, Santon Downham -4.0C minimum, Harris Quidnish 41.0 mm, East Malling 12.3 h (suspiciously high.))

A slow-moving front gave some rain on the 25th across W Ireland and in N, W and Cent Scotland, with snow over high ground. Clear skies under high pressure led to an air frost in Cent areas of England and in nearby counties. Scotland had a rather cloudy and mild night. With little cloud during the day, England, Wales and parts of E Ireland had another very sunny day; elsewhere it was generally dull. England, Wales and E Ireland had a mild day, although some E coast areas of England remained cool. Relative humidity was as low as 20% in parts of S England in the afternoon. (Bala 18.2C, Loch Glascarnoch 7.5C, Santon Downham -4.3C minimum, Achnagart 16.0 mm, Jersey Airport 12.2 h.)

The 26th was another very sunny day across England and Wales, although much of N Ireland and S and Cent Scotland remained rather dull. This dullness was due to a slow-moving front that marked the S limit of cooler conditions. Scotland and Ireland had some scattered light rain and drizzle overnight that moved slowly S'wards into parts of N England during the day. Under clear skies there was an air frost in most areas of England at first while temperatures of 13-15C were recorded in many areas of England and Wales due to the sunshine. (Levens Hall 18.0C, Salsburgh 6.6C maximum, South Newington -5.3C minimum, Derrylin Cornahoule 3.4 mm, Aberporth 12.1 h.)

Pressure rose during the 27th across Scotland, reaching 1937 mb at Stornoway by late evening. Inland areas of England, Wales and parts of N Scotland had an early air frost followed by a sunny day, especially across England and Wales. W Ireland was also very sunny much of England, Wales and W Ireland were cloudless all day and daytime temperatures reached 14 C and above in places. Cloud skies gave some light rain and drizzle in E and S Scotland at times. (Porthmadog 16.2C, Salsburgh 5.8C maximum, Bala -4.8C minimum, Edinburgh Botanic Gardens 2.6 mm, Aberporth 12.2 h.)

There was little air frost over the British Isles on the 28th due to brisk winds and/or cloud cover. There was some light rain overnight across N Scotland as pressure continued to rise and cold fronts edged S'wards over N areas of Britain. The day was fairly cloudy and chilly with a fresh NE'ly wind, and a few mostly light showers in the north and east. It was sunnier and warmer towards the south coast of England. By 1900 GMT MSL pressure had risen to 1048.2 mb at Stornoway; prior to this, the MSL pressure on 3 March 1990 at St Mary's Airport, Isles of Scilly of 1047.9 mb was the highest UK air pressure in March. (Hurn 13.8C, Lerwick 3.9C maximum, Bala -3.1C minimum, Resallach 2.4 mm, Camborne 11.5 h.)

Air pressure continued to rise a little further in NW areas on the 29th; Malin Head peaked at 1051.3mb at 1100 GMT, the highest British Isles air pressure on record. As a result, an unusually strong N/NE'ly wind blew across the British Isles. There was some sunshine, especially in the W where temperatures were locally not far from normal, but most places were cold and it was rather showery in the E and SE; some of the showers were heavy over East Anglia and Kent, with hail, snow - and even a sferic northeast of Lewes (with pressure 1035 mb at the time). Any early air frost was mainly confined to parts of N Ireland and S Scotland. (Usk No.2 10.1C, Bainbridge 4.3C maximum, Castlederg -2.5C minimum, Resallach 4.2 mm, Camborne 11.2 h.)

Pressure remained high on the 30th with a large centre over the Atlantic. Patchy overnight cloud led to an air frost mainly across parts of Ireland and W areas of Britain. Areas close to the E coast had overnight showers and these spread further W'wards during the day. Most areas, however, had some sunny spells. (Glasgow 13.5C, Lake Vyrnwy 6.2C maximum, Trawsgoed -4.0C minimum, Resallach 7.4 mm, Boulmer 10.7 h.)

The 31st was a rather cloudy day and there was little air frost overnight. The E half of England had some overnight rain showers while during the day showers were confined to some N and E areas of Scotland. It was a cool day close to the E coast under the onshore winds. (Porthmadog 13.0C, Pennerley 6.2C maximum, Katesbridge -2.9C minimum, Resallach 4.6 mm, Shoeburyness 11.7 h.)

British Isles weather, April 2020

A weak ridge of high pressure extending from the W gave most areas a dry day on the 1st - although it was rather cloudy away from the Channel Islands due to a weak front moving S'wards across Scotland. Ahead of this cloud there was an early air frost across the Midlands, S England and parts of S Wales, and in East Anglia. The rain was generally patchy, over Scotland and N Ireland overnight, later spreading as far S as N England and N Wales. It was mostly rather cold - and cold over a large central area of England, especially where the cloud arrived soon after the frost. (Leuchars 12.9C, Pennerley 5.8C maximum, South Farnborough -5.2C minimum, Resallach 9.8 mm, Jersey Airport 12.2 h.)

Pressure fell over Scandinavia on the 2nd and a series of fronts pushed S'wards across much of the British Isles, introducing colder air from the N. There was an isolated air frost in parts of E England overnight, with most of the overnight rain being across N Scotland. As the wind speeds increased, especially in N areas, there were peak gusts of 65 mph at Leeds Bradford Airport and 67 mph at Emley Moor. During the day N Scotland was showery, and there was some patchy rain elsewhere, especially in the W mostly as far S as S Ireland and the Midlands by early evening. Across N Scotland and over high ground in Cent Scotland the precipitation fell as snow at times. The best of the sunshine was to be found over N and E Scotland. (Gosport Fleetlands 15.1C, Loch Glascarnoch 4.5C maximum, Santon Downham -1.8C minimum, Resallach 13.2 mm, Leuchars 8.0 h.)

Pressure was high to the S on the 3rd (1020 mb over SW Cornwall at 1200 GMT). E and Cent areas of Scotland had an air frost at first, and this was followed by outbreaks of rain spreading from the W, whilst there were further wintry showers in N Scotland in the morning. Light rain also fell as far S as Cent Ireland and N England although the S half of Britain remained largely dry with some sunshine. It was a cold day across Scotland. (Cardiff Bute Park 14.9C, Baltasound 3.7C maximum, Tulloch Bridge -4.3C minimum, Resallach 10.4 mm, Jersey Airport 9.0 h.)

A S'ly flow affected most areas on the 4th with air frost largely confined to parts of NE Scotland ahead of the advancing warm front. There were a few mist and fog arches across S England and S Wales around dawn, but these soon cleared and a mainly dry day followed - except over N Scotland at times. It was sunny and warm over S England and East Anglia, while Ireland, N England and Scotland had a rather cloudy day. (St James Park 17.3C, Lerwick 7.2C maximum, Baltasound -3.5C minimum, Baltasound 11.0 mm, Jersey Airport 12.4 h.)

A brisk S'ly flow was maintained on the 5th although many areas of Cent England and E Scotland had an early ground frost. There was a little frontal rain in SW Ireland by dawn this spread across much of Ireland and W and N Scotland by the evening. SE Scotland and much of England (especially E areas) had a warm and sunny day; it was also warm in Wales. (Porthmadog 22.2C, Inverbervie 8.4C maximum, Santon Downham -1.4C minimum, Cardinham 4.8 mm, Shoeburyness 12.6 h.)

Cold fronts crossed all areas on the 6th, followed by a rise in pressure (close to 1025 mb on the Channel Islands by 1800 GMT). Rain fell in most paces although falls in E England were mainly slight. Overnight minimum temperatures remained above 10C in the E half of England. Showers followed the rain (mainly in N areas) while daytime temperatures were generally above normal with most places having sunny spells, and it was warm over eastern England. (Frittenden 18.8C, Dalwhinnie 8.5C maximum, Okehampton 5.3C minimum, Tyndrum 16.0 mm, Aberdaron 12.3 h.)

High pressure (1030 mb over East Anglia around dawn) on the 7th led to a slight air frost overnight in a few sheltered areas of the British Isles. There were also a few mist of fog patches in some places before sunny conditions followed in most areas. However, it turned cloudier in many places - from the NW over Scotland and Ireland, with some rain in the far N, and from the SW over England and Wales with light showers in SW England. (Northolt 20.4C, Harris Quidnish 9.4C maximum, Sennybridge -3.1C minimum, Baltasound 2.6 mm, Aberdaron 12.5 h.)

Pressure remained high on the 8th but a slow-moving cold front moved S'wards across Scotland giving some patchy rain here and in N Ireland at times. There was a slight air frost in parts of SE Scotland and NE England but most of England, Wales, the Channel Islands and S Ireland had a sunny day with varying amounts of cloud. It was also warm across much of England, Wales and the Channel Islands. The cold front brought a marked-temperature fall in places as it moved S: at Aboyne the temperature was 15.5C at 1500 GMT and 5.7C at 1800 GMT. (Herstmonceux 23.9C, Loch Glascarnoch 6.6C maximum, Kielder Castle -0.5C minimum, Lentran 8.4 mm, Guernsey Airport and Morpeth Cockle Park 12.0 h.)

There was an air frost in N Scotland on the 9th with mist and fog patches under clear skies across parts of England, Wales and Ireland. Despite prevailing high pressure, a slow-moving front led to cloudy skies across N England and Cent and S Scotland during the day. Elsewhere, it was a largely sunny day and quite warm in places over the S half of Britain. (Wiggonholt 24.4C, Baltasound 7.0C maximum, Kinbrace -6.7C minimum, Glasgow 2.6 mm, Jersey Airport 12.3 h.)

There was some light rain overnight into the 10th across N Scotland; elsewhere the day dawned with scattered patches of mist or fog. A sunny day followed over S and Cent areas of England and Wales but with cloudier skies due to fronts across Ireland and Scotland. England and Wales had a warm day inland. Showery outbreaks drifted NNE across W and N Wales, and parts of NW England, Scotland and Northern Ireland during the afternoon and evening; there was thunder in a few districts, especially over N Wales and Lancashire. Jersey Airport 25.2C, Lerwick 7.3C maximum, Loch Glascarnoch 1.9C minimum, Thomastown 7.6 mm, Manston and Shoeburyness 12.6 h.)

Many areas dawned with mist or fog patches on the 11th, with some patchy rain across Scotland. England, Wales and S Ireland had a mainly sunny day, but further N there were areas of cloud that gave some light rain in parts of Scotland and N Ireland. The sunshine triggered a few sharp showers, with thunder briefly on Dartmoor in the early afternoon. It was rather cold over N Scotland, but quite warm in inland areas of S England. (St James Park 25.5C, Fair Isle 8.8C maximum, Santon Downham 2.1C minimum, Baltasound 6.4 mm, Aberporth and Camborne 12.3 h.)

A N'ly flow led to cold conditions slowly pushing S'wards across Scotland on the 12th behind a cold front that gave some rain in N areas of the UK. Heavier rain fell during the day over parts of S Ireland; 18 mm fell in the 12 hours ending 1800 GMT at Cork Airport. Some showers occurred in warmer air further S, with thundery activity during the afternoon and early evening over East Anglia and the E and N Midlands. The best of the warm and sunshine was to be found in these thundery areas and in Cent S and SE England. (St James Park 25.0C, Lerwick 5.8C maximum, Dalwhinnie 1.0C minimum, Hawarden 10.2 mm, Reading University 11.4 h.)

High pressure built from the W during the 13th (centre 1032 mb over the S Western Isles at 1800 GMT), pushing the cold N'ly surface flow partially away to the E. Parts of N England and Scotland had a slight air frost, while there were outbreaks of rain overnight over Cent and E England as cold air pushed S'wards across the country. The day was mainly dry and sunny; it was particularly sunny across Wales and Ireland although parts of E England remained dull. (Valentia 16.1C, Lerwick 4.0C maximum, Dalwhinnie -0.7C minimum, Pennerley 19.4 mm, Rostherne 12.9 h.)

High pressure dominated weather over the British Isles on the 14th. Away from coastal areas and E England, there was a widespread air frost which was unseasonably sharp in parts of Scotland. A sunny day then followed, except across N and Cent Scotland where there was more extensive cloud and some rain. Some areas, however, had a relatively cool day although parts of N Wales, NE England, E Scotland and Cent and Northern Ireland became warm. At Aboyne, the temperature rose from -6.3C to 16.1C. (Helens Bay 16.8C, Lerwick 7.6C maximum, Redesdale Camp -6.7C minimum, Baltasound 3.2 mm, Aberporth 13.1 h.)

High pressure on the 15th led to a widespread air frost at first, although it was relatively mild under cloudy skies across N Scotland. The day brought prolonged sunshine in most areas, although not across N and W Scotland. It was warm in parts of E Scotland and NE England, while places in N Scotland had some light rainfall. (Durham 21.2C, Fair Isle 8.8C maximum, Katesbridge -4.2C minimum, Cassley 1.4 mm, Eskdalemuir 13.3 h.)

Pressure remained high on the 16th, but cloud bands reduced the sunshine totals across Scotland and some SW areas of the British Isles. Overnight there was some slight rainfall across N Scotland and a few pockets of air frost in sheltered places across the UK and E Ireland. Much of England, Wales and Cent and E Ireland had a sunny day. Patchy light rain moved NE'wards across southern England, and thunderstorms drifted N'wards across the eastern English Channel in the evening with rain reaching the Isle of Wight. (St Helier 22.5C, Lerwick 8.4C maximum, Santon Downham -2.1C minimum, Resallach 1.0 mm, Morecambe 13.1 h.)

On the 17th many Cent and N districts were quite sunny, although areas of low cloud did drift in from the North Sea to some areas, especially across southern Scotland. Parts of N and E Scotland had an air frost, but over S England, Wales and S Ireland the night was mild. Wales, the W half of England and parts of Ireland were rather cloudy during the day. This cloud tended to spread NE'wards southern Britain with outbreaks of rain, some of them heavy, slowly following; there was thunder later in the Channel Islands and a fairly extensive thundery outbreak moved north into the eastern English Channel. Porthmadog 18.1C, Kielder Castle 8.6C maximum, Aboyne -5.4C minimum, Thorney Island 20.6 mm, Stornoway 13.6 h.)

Low pressure and frontal cloud led to a rather cloudy day on the 18th in many areas, although it was generally a sunny day across Scotland and parts of Northern Ireland after an early air frost in parts of N Scotland. Overnight there was rain across Wales and the S half of Ireland and England; this made little further progress N'wards during the day; there was some heavy rain at first, with thunder briefly over NE Kent, but the rain slowly died out. Aviemore was both the coldest (by night) and the warmest (by day) place. (Aviemore 16.5C, Lake Vyrnwy 5.2C maximum, Aviemore -5.4C minimum, Lyneham 25.6 mm, Kinloss and Stornoway 13.7 h.)

High pressure prevailed in all areas on the 19th (1028 mb on Shetland at 1200 GMT). Many inland areas of Scotland had an air frost before much of the UK had a sunny day with over 12 h of bright sunshine in many areas. An exception to this was a cloudier SW England, while Ireland was rather dull with some light rain in places. (Kinlochewe 19.7C, Fair Isle 9.1C maximum, Aboyne -6.9C minimum, Katesbridge 0.6 mm, Stornoway 13.9 h.)

Parts of N England, N and E Scotland had an air frost into the 20th. A largely sunny day followed in most areas with 12-13 h of sunshine being widely reported. An exception was part of SW England; here it clouded over and there was rain over the Channel Islands in the evening. (Cardiff Bute Park 19.1C, Inverbervie 10.0C maximum, Braemar -5.7C minimum, Baltasound 0.4 mm, Kinloss 14.2 h.)

There was some rain overnight into the 21st in the Channel Islands and parts of SW England with an air frost in parts of Cent Scotland. Much of the UK then had a sunny day with 10-13 h of bright sunshine, although parts of SW England and S Ireland were dull with an area of rain moving NW'wards here. It was warm in parts of Wales and S England but cooler near the E coast of the UK due to an E'ly wind around an area of high pressure. (Porthmadog 20.9C, Fair Isle 10.7C maximum, Braemar -5.9C minimum, Isles of Scilly 2.6 mm, Kinloss 14.2 h.)

The UK and NE parts of Ireland had a sunny day on the 22nd after an air frost in Cent Scotland. Ireland was cloudier due to a weak front offshore to the SW. Away from the North Sea many areas had a warm day due to the prolonged sunshine. (Hurn 22.6C, Baltasound 10.2C maximum, Braemar -4.8C minimum, St James Park 0.2 mm, Kirkwall 13.8 h.)

Weak pressure gradients on the 23rd resulted in a sunny day in S England and the N half of mainland Scotland, following an air frost in some N and E areas of Scotland overnight. It was dry across the British Isles and quite mild in most areas away from the E coast of the UK once some early mist had cleared from parts of Ireland, Wales and England. (Herstmonceux 24.3C, Fair Isle 8.5C maximum, Altnaharra -4.1C maximum, Houghton Hall 0.2 mm, Kinloss and Stornoway 14.2 h.)

The 24th was a mainly dry day following some overnight air frost in parts of Scotland and N England. There were some early mist and few fog patches across the S half of England, Wales and Ireland before dawn. During the day, away from Shetland, W Ireland and the Channel Islands there was widespread, prolonged sunshine with over 12 h of bright sunshine in many areas of England, E and N Scotland. Away from coastal influences, many of these sunny areas were quite mild. (Porthmadog 23.2C, Wick Airport 8.7C maximum, Kinbrace -5.0C minimum, Aberporth 0.4 mm, Altnaharra 14.1 h.)

Winds were mainly light under slack pressure gradients on the 25th. After a slight air frost in parts of N and E Scotland the day was generally dry everywhere although misty at times in parts of SW England and S Ireland. Away from W Ireland and SW England, mainland areas of the British Isles were quite sunny. A few light showers developed over mid-Wales. (Aviemore 20.7C, Inverbervie 8.0C maximum, Altnaharra -2.3C minimum, Trawsgoed 0.4 mm, Dundrennan 13.6 h.)

During the 26th patchy areas of rain initially across NW Scotland spread SE'wards during the day, but gave only light falls in most areas away from N Scotland. Much of England, Wales and S Ireland had a misty start to the day. Bands of showery rain affected W and N Wales, the N Midlands and N England (with a sferic near Oswestry in the early afternoon). Areas SE of a line The Wash-Exeter had a very sunny day as did parts of S Scotland; however, much of Ireland was rather dull. The best of the warmth was to be found in and around East Anglia (triggering some heavy rainfall in places), while areas of W Scotland and Cent Ireland were quite cool. (Holbeach 22.4C, Baltasound 8.0C maximum, Santon Downham -1.7C minimum, Normanby Hall 8.2 mm, Wattisham 13.5 h.)

S'ward moving fronts led to a rather cloudy day in many areas on the 27th, although parts of E Ireland, W and S Scotland and parts of N England were quite sunny. Many places across N Ireland, S and Cent Scotland had an early air frost across N Scotland, N England and S Ireland there was some overnight rain. During the day, the heaviest falls were mainly confined to parts of N and W Scotland. (Frittenden 20.6C, Lerwick 8.4C maximum, Katesbridge -3.4C minimum, Glasgow 7.0 mm, Morecambe 13.9 h.)

The 28th was a cloudy day in many areas sunless across most of England and Wales but with some long spells of sunshine in parts of E and W Scotland close to the coasts. This dullness was the result of a shallow low pressure system (centre 1002 mb at 1200 GMT over SE Devon) that pushed frontal rain N'wards across most of England and Wales by late evening. In places this rain was heavy and prolonged. Parts of Scotland and N Ireland had an overnight air frost and a cooler day than of late followed in many areas with many areas of Cent England failing to reach 8C during the day. (Claremorris 15.9C, Lake Vyrnwy 5.9C maximum, Braemar -6.0C minimum, Middle Wallop 23.6 mm, Stornoway 13.4 h.)

Bands of rain moved NE'wards across the country on the 29th, with drier, brighter intervals between them. It was mostly rather cool, after some overnight air frost in N, E and Cent Scotland. (Yeovilton 15.4C, Spadeadam 7.0C maximum, Braemar -5.2C minimum, Mumbles Head 22.6 mm, Stornoway 11.4 h.)

Low pressure, centre 987 mb over the Isle of Man at 1200 GMT, dominated the weather on the 30th. It was very showery over most areas, especially England and Wales, with limited sunshine. There was thunder in a few districts, chiefly over E and S England. It was generally chilly and, in the south, breezy. (Kinlochewe 16.0C, Lerwick 7.5C maximum, Shap 0.9C minimum, Capel Curig 33.8 mm, Manston 8.9 h.)

British Isles weather, May 2020

Low pressure to the E of the British Isles on the 1st drew a showery, N'ly flow across most areas. There was an early air frost in parts of Northern Ireland and Cent and S Scotland. Away from a rather cloudy N half of Scotland, most places had some sunny spells especially in Ireland and some W areas of England and Wales. Hail fell in places and there was mostly isolated thunder, although with more pronounced thundery activity over East Sussex in the afternoon. (Edinburgh Botanic Gardens 16.1C, Fair Isle 8.0C maximum, Katesbridge -2.1C minimum, Myerscough 12.0 mm, Shannon Airport 11.9 h.)

After overnight showers in various districts on the 2nd, showers during the day were largely confined to N and E areas of Scotland. Elsewhere, away from some North Sea coastal areas, it was a sunny day. Frontal rain spread into parts of S Ireland, SW England and the Channel Islands in the evening after a mild day in many places. (Kew Gardens and St James' Park 18.0C, Fair Isle 9.5C maximum, Katesbridge -0.4C minimum, Scarborough 4.8 mm, Prestwick 13.9 h.)

Fronts led to a cloudy day on the 3rd in much of S and Cent England and also in a few E areas of the UK. W Scotland and E areas of Ireland had a sunny day. It was showery across the cloudier areas of Scotland and in N England; some of these were heavy and thunder occurred locally over NE England. Parts of N and E Scotland and Northern Ireland had an early air frost, but it was a warm day across SW Scotland, N and Cent Ireland and in parts of N England. (Carlisle 17.7C, Loch Glascarnoch 9.2C maximum, Kinbrace -6.6C minimum, Pateley Bridge Ravens Nest 14.6 mm, Ronaldsway 14.2 h.)

Pressure rose on the 4th, with a centre just NW of Orkney at 1027 mb by 1800 GMT. Parts of Scotland, N England and Northern Ireland had a slight air frost at first. There was some patchy rain overnight (mainly slight) in many areas, but during the day this was largely confined to parts of NE England and E Scotland. Parts of SW Ireland and SW England were affected by another area of rain in the evening. Much of Ireland and W Britain, away from the SW) had a very sunny day. (Porthmadog 20.1C, Baltasound 8.0C maximum, Kinbrace -3.0C minimum, Aviemore 8.2 mm, Ronaldsway and Tiree 14.3 h.)

Despite high pressure prevailing generally on the 5th, an area of heavy rain moved NW'wards across SW England overnight, weakening during the day but still affecting parts of S Wales, SW England and S Ireland at times. Parts of E and Cent Scotland, and a few places in N England, had an overnight air frost before most places (away from the rain area) had a very sunny day. (Porthmadog 18.6C, Fylingdales 9.9C maximum, Kinbrace -3.9C minimum, Culdrose 33.6 mm, Dundrennan 14.3 h.)

After some overnight air frost on the 6th as far south as Norfolk (with ground frost as far S as Hampshire), it was sunny nearly everywhere, and warmer especially over Scotland. Cornwall and the Northern Isles were cloudier, as was S Ireland where 12 mm fell at Cork Airport in the 12 hours ending 0600 GMT. (Aviemore 21.0C, Fair Isle 9.3C maximum, Kinbrace -4.3C minimum, Wych Cross 0.2 mm, Altnaharra 14.9 h.)

After overnight frost over parts of Scotland and northern England on the 7th, it was mostly sunny and warm, but a few showery outbreaks moved NE'wards across Ireland and through N and W districts of the UK, with isolated thunder over N Wales in the afternoon. 5 mm of rain fell a Valentia in the 12 hours ending 1800 GMT. (Kew Gardens 23.2C, Fair Isle 10.4C maximum, Kinbrace -2.8C minimum, Lough Fea 4.0 mm, Weybourne 14.2 h.)

Pressure gradients were slack into the 8th and widespread patches of cloud led to a night that was free of air frost at low levels only the second nationally frost-free night in the last three weeks. It was a rather cloudy day across mainland Scotland and SW England, with varying amounts of sunshine elsewhere. It was a mainly warm day, with some showers and some isolated thunder over S Wales and the Midlands. Cool air, preceded by some heavy bursts of rain, edged S'wards into N Scotland. (Kew Gardens" 24.5C, Fair Isle 10.2C maximum, Katesbridge 3.4C minimum, Drumnadrochit 20.2 mm, Hurn 13.4 h.)

During the 9th cold, wet weather continued to drift S'wards over N Scotland, but it was still mostly warm, locally very warm, and quite sunny elsewhere. A large area of showers, with some thunder, developed over Wales in the afternoon, and moved across Staffordshire with some vigour in the evening. There were a few other heavy showers over the Midlands and N England, with thunder around the Tees Estuary. Properties were flooded after thunderstorms hit parts of south and west Wales. Four houses were damaged in Carmarthen while fire crews were called to flash flooding in Gorseinon, Swansea. (Northolt 24.9C, Fair Isle 6.9C maximum, Shap 2.0C minimum, Keele 19.8 mm, Valley 14.4 h.)

A large anticyclone to the W of Scotland drew cold air S'wards across E areas of the UK on the 10th as a cold front pushed S'wards. There were outbreaks of rain overnight over Cent and N districts with a little thunder over NE England. Where skies were clearer in parts of N Scotland there was a slight frost. Cold, blustery weather continued to extend southwards during the day, after a warm start in the south; it reached the far SW in the late afternoon. There were showery outbreaks in various districts, with snow in Scotland - which also had the best of the sunshine. It was very cold over much of northern England and Scotland; maxima were around 14 degC lower than 24 bours earlier in parts of the Lake District and N Yorkshire. (Plymouth 23.0C, Fair Isle 4.9C maximum, Lerwick -1.6C minimum, Coningsby 10.4 mm, Tiree 13.7 h.)

The 11th was a cool day due to the continuing N/NE'ly anticyclonic surface flow. Air frost occurred in places as far S as Cent Ireland and S Wales but during the day there were sunny spells, especially across parts of Wales, SW Scotland and over Ireland. There were also some light showers, some of them wintry, in N and E areas of the UK. (Hurn 14.2C, Fylingdales 7.2C maximum, Tulloch Bridge -5.2C minimum, Resallach 2.6 mm, Dundrennan 14.7 h.)

An air frost was widespread on the 12th across England, Wales and parts of E Ireland with minimum temperatures falling below -3C in places. There was also a widespread ground frost outside of Scotland. During the day a cold front moved S'wards across Scotland and into N Ireland and N England later, giving cloud and outbreaks of rain. Colder air followed the rain, with some wintry falls in N Scotland. Further S, it was a mainly sunny day after a few early showers in parts of Kent. (St James Park 16.3C, Lerwick 5.5C maximum, Sennybridge -4.7C minimum, Fair Isle 8.8 mm, Bude 14.3 h.)

There was an air frost in parts of Scotland, Wales and N England on the 13th - with a widespread inland ground frost in most inland areas of the British Isles. A weakening cold front pushed S'wards across England, Wales and Ireland, but it gave little precipitation. The day was mostly quite cold and rather breezy with some sunshine and a few more mostly light, but occasionally wintry, showers in N Scotland. (Porthmadog 15.0C, Braemar 5.4C maximum, Tulloch Bridge -5.0C minimum, Killylane 2.4 mm, Valley 13.5 h.)

High pressure and a flow from the N on the 14th led to a widespread air frost across the British Isles, except in some S areas of England and Ireland. There were showers across N and Cent Scotland, in particular, during the day but across most of England, Wales and Ireland it was very sunny. (Leeming 16.7C, Fair Isle 9.2C maximum, Katesbridge -6.1C minimum, Loch Glascarnoch 4.2 mm, Aberdaron 15.0 h.)

The 15th dawned after an air frost in parts of England and Wales; a very sunny day followed across most of England (except for some N areas). Elsewhere it was a cloudier day with some showers over Scotland and N Ireland. E and S areas of England had a warm day but it was cooler across N and W areas of the British Isles. (Heathrow 19.6C, Baltasound 8.3C maximum, Santon Downham -3.4C minimum, Altnaharra 5.2 mm, Shoeburyness 14.9 h.)

While high pressure dominated conditions across S areas of the British Isles on the 16th, there were outbreaks of light rain and showers across areas of Scotland and Ireland. There were sunny spells over England and Wales, after an early ground frost in many parts of England, but patchy cloud meant the best of the sunshine was confined to parts of Cornwall and the Channel Islands. (Pershore 19.2C, Baltasound 5.7C maximum, South Newington 1.1C minimum, Achnagart 6.6 mm, Jersey Airport 12.2 h.)

Parts of Cent England had a ground frost into the 17th, but in W Ireland overnight minimum air temperatures were around 10-11C. Scotland, Ireland and parts of N England had a cloudy day with some rain. There were sunny spells in S England where it was also a warm day. (Heathrow and Holbeach 21.1C, Kirkwall 8.6C maximum, South Newington 1.3C minimum, Dunstaffnage 15.4 mm, Guernsey Airport 13.3 h.)

Cloudy skies across the British Isles led to a mainly mild night into the 18th, except in the Northern Isles. There was patchy rain across Scotland, Ireland and N England overnight and during the day but S England and the Channel Islands had a mainly sunny day. It was generally warm in the E and S (very warm in parts of SE England and East Anglia), but rather chilly in the west and north. (Cavendish 24.6C, Lerwick 7.9C maximum, Baltasound -1.0C minimum, Achnagart 24.8 mm, Guernsey Airport 14.0 h.)

It was mild, wet night into the 19th from Cent Scotland to the Midlands. It was a cool night across N Scotland, but generally mild elsewhere. N Ireland, N England and Scotland had a rather cloudy day with light rain during the day in some of these areas although the rain gradually became confined mostly to N Scotland. It was mostly sunny over SE areas of Britain. It was chilly in N Scotland, but mostly warm elsewhere away from windward coasts in the S and W. (St James Park 26.2C, Baltasound 8.8C maximum, Altnaharra 1.8C minimum, Blencathra 19.0 mm, Wellesbourne 13.4 h.)

The British Isles lay under the warm S'ly flow of a warm sector on the 20th. After a mild night (minimum temperatures remained above 12C overnight in parts of N Scotland) the day was generally very sunny; it was, however, cloudier across N Scotland with some light rain in places here. It was foggy around Shetland, and at first in parts of Cornwall. It was very warm or hot, except in the more exposed W or N areas. (Santon Downham 28.2C, Baltasound 9.8C maximum, Shap 4.2C minimum, Dunstaffnage 1.6 mm, Morecambe 15.1 h.)

A cold front pushed E'wards across all areas of the British Isles on the 21st, although there was little rainfall as a result across England and Wales. There was a ground frost in parts of E Scotland, but in general both the night and the day were warm. there was thunder in the early hours in parts of Cornwall, southernmost and northernmost Wales, and in the morning around parts of the East Anglian coast. E and S England had a sunny day, but there was a little more cloud in W areas of the British Isles once the cold front had passed. Temperatures widely reached 25C in East Anglia and Cent S and SE England. (Manston 27.8C, Baltasound 12.4C maximum, Eskdalemuir 1.4C minimum, Stornoway 7.4 mm, Reading University 11.8 h.)

A deep area of low pressure close to Scotland on the 22nd (MSL pressure down to 984 mb on the Isle of Lewis at 1800 GMT) gave some heavy rain across Scotland and Ireland overnight and into the morning, followed by showery conditions here and over N England. It was a very warm night in many parts of East Anglia, N Kent, the London area and the Thames Valley where overnight minimum temperatures remained above 15C in many places. E and S Ireland, and many areas of England and Wales, had a sunny day, although cloud amounts were variable and reduced the sunshine in places. Rain moved northeast across most of the country, but there was little or none over most of SE Britain. W Scotland remained rather dull, and the best of the warmth was to be found in E Britain. It was very windy in Scotland. (Heathrow 23.2C, Dalwhinnie 10.8C maximum, Kinbrace 6.3C minimum, Achnagart 73.4 mm, Aberdaron 13.8 h.)

Low pressure close to Scotland on the 23rd led to a windy day in all areas. Scotland and Ireland had spells of rain and showers, with some of these showers affecting parts of England and Wales although many areas saw no more than a trace of rain. S England and S Ireland had a mainly sunny day; elsewhere it was rather cloudy. S Britain had sunny spells and a scattering of showers, with thunderstorms towards the SE coast in the early afternoon. Strong winds were still helping spread a forest fire which has been burning for six days in Dorset. More than 150 firefighters remain at Wareham Forest dealing with hotspots and flare-ups. About 200 hectares have so far been damaged. A helicopter was brought in to "water bomb" the area as smoke drifted as far as Bournemouth. Dorset and Wiltshire Fire and Rescue Service said winds of up to 45 mph were proving a "huge risk". (Weybourne 20.1C, Drumalbin 9.1C maximum, Dalwhinnie 4.9C minimum, Achnagart 68.2 mm, Jersey Airport 12.7 h.)

High pressure on the 24th (centre 1036 mb near Scilly at 1200 GMT) gave a more settled day's weather today. The day dawned after a mild night that brought some rain to parts of Scotland, Ireland and N England. The day was mainly dry, except across N and Cent Scotland as a warm front pushed N'wards here. S Ireland, much of Wales and S England and the Channel Islands had a sunny day. (Teddington Bushy Park 23.5C, Fair Isle 9.9C maximum, Aviemore 7.1C minimum, Keswick 8.8 mm, Cork Airport 13.7 h.)

The 25th was a warm day in many areas, and a very sunny day over England and Wales. Overnight, there was a slight ground frost in parts of the UK and NE Ireland. Cloud, followed by frontal rain, spread from the W as the day developed, with rain falling across Ireland and Scotland later in the day. Temperatures rose above 25C in parts of the London area and East Anglia. (Teddington Bushy Park 26.6C, Harris Quidnish 12.4C maximum, Aboyne 0.0C minimum, Harris Quidnish 2.6 mm, Shawbury 15.0 h.)

Pressure remained high on the 26th (close to 1038mb in W Ireland at 1800 GMT); a weak front gave some light rain overnight across Ireland, S Scotland and N England, but this mostly died out by late morning. A mild night was followed by a warm day, with temperatures reaching 25C in parts of Cent S England and the London area. It was especially sunny in S England, N Ireland and in many areas of Scotland. (Kew Gardens 26.9C, Fair Isle 11.9C maximum, Tulloch Bridge 4.0C minimum, Tyndrum 1.6 mm, Guernsey Airport 14.8 h.)

High pressure on the 27th (centre 1038 mb over the Isle of Man at 1200 GMT) led to a generally dry and warm day. A weak front did, however, give some light rain in parts of W Scotland and N Ireland. It was a sunny day in much of England, Wales, E and S Ireland and in E Scotland while daytime temperatures reached 25C in parts of S England. (Heathrow 26.3C, Fair Isle 11.3C maximum, Shap 1.0C minimum, Stornoway 2.4 mm, Guernsey Airport 14.8 h.)

High pressure on the 28th led to a sunny day across S Scotland, Ireland, Wales and England, although frontal cloud produced some E'ward-moving rainfall across N Scotland overnight and into the morning. Away from the coasts, it was a very warm day in places, particularly in parts of E Scotland. The Northern Isles, however, remained rather dull and cool all day with some mist and fog. (Leuchars 25.7C, Lerwick 10.0C maximum, Ravensworth 2.3C minimum, Resallach 17.8 mm, Weybourne 15.1 h.)

The 29th dawned following a warm night across Ireland (overnight minimum temperatures remained above 15C in parts of W Ireland) but it was noticeably cooler in E areas of the UK close to the North Sea. Pressure remained high but an onshore breeze kept it cooler in these E areas during the day (maxima below 18C in places) than further inland. Much of England, Wales, E Ireland and many areas of Scotland had largely unbroken sunshine during the day but on Shetland there was some cloud, light drizzle, mist or fog at times and it was a dull day as result. It was warm over most of the country, and hot in parts of the west and north. (Kinlochewe 28.0C, Lerwick 11.3C, Santon Downham 2.9C minimum, East Malling 0.2 mm, Morecambe 15.5 h.)

The 30th dawned after a generally mild night, especially in parts of W Scotland and W Ireland. However, it was cooler in some E areas with a ground frost in parts of NE England. The day brought widespread, prolonged sunshine to all areas. It was warm or very warm, but locally hot with maximum temperatures above 25C in some areas. Lowest temperatures during the day were along North Sea coasts in an onshore wind. (Kinlochewe 27.5C, Fair Isle 12.3C maximum, South Newington 2.6C minimum, a trace in a few places, Morecambe 15.7 h.)

The 31st dawned after a slight air frost in parts of E Scotland. Elsewhere it was a generally mild night, while the day was again warm or very warm in all areas, but cooler along the North Sea coast. There was widespread prolonged sunshine with little cloud across the British Isles; temperatures reached 25C in parts of Ireland, Wales and England. (Porthmadog 28.0C, Fair Isle 13.2C maximum, Braemar -1.3C minimum, a trace in a few places, Kirkwall 16.6 h.)

British Isles weather, June 2020

Slack pressure gradients under high pressure on the 1st led to a warm and sunny day in most places, after a slight ground frost in some sheltered parts of N England and E Scotland. There was over 10 h of bright sunshine almost everywhere. (Porthmadog 27.6C, Fair Isle 12.5C maximum, Aboyne 1.1C minimum, High Mowthorpe 0.2 mm, Waddington 15.6 h.)

A cold front spread cloud SE'wards across Scotland and Ireland on the 2nd, giving some rain that spread S'wards into parts of N England and S Ireland by the evening. Sunny conditions across S Ireland, Wales, Cent and S England led to a warm day here. (Gosport Fleetlands 26.9C, Fair Isle 9.6C maximum, Ravensworth 2.9C minimum, Strathallan 13.4 mm, Guernsey Airport 15.0 h.)

The cold front continued to move S'wards on the 3rd but by midday was semi-stationary across Cent areas of England. Minimum temperatures remained above 14C in parts of S England overnight but away from W Ireland and SW Scotland there was little sunshine during the day. Falls of rain were heavy across Wales and N England and temperatures were close to normal in S England. (Cavendish 20.9C, Craibstone 9.8C maximum, Altnaharra 4.9C minimum, Shap 19.2 mm, Magilligan 11.5 h.)

A N'ly airflow on the 4th led to a mainly cloudy and cool day. Overnight rain cleared SE England before dawn and the day was then one of SE'ward-moving showers. Much of S England and S Ireland remained dry during the day but the best of the sunshine was mainly to be found across N Scotland. (Murlough 18.6C, Balmoral 9.8C maximum, Aboyne 1.3C minimum, Drumalbin 17.0 mm, Kirkwall 6.1 h.)

Pressure remained low to the E of Scotland on the 5th (with a centre down to 975 mb on the Greenwich meridian to the E of Aberdeen at 1800 GMT). Outbreaks of rain spread SE'wards overnight in many areas, with a showery day following. Across N areas of Scotland the rain was more extensive and slow-moving towards the S during the day. There was thunder in parts of England and Wales; a house was set on fire by lightning at Gowerton in Swansea around 1700 GMT. Away from N Scotland most places had some sunny spells but except in Cent S England it was a cool day. (Hurn 19.2C, Braemar 7.9C maximum, Redesdale Camp 2.0C minimum, Hull East Park 24.4 mm, Ronaldsway 12.2 h.)

Overnight rain across Scotland and N England early on the 6th moved slowly S'wards during the day, becoming more showery as it did so. The frontal band curved back over W and N regions to give light rain over Ireland, before returning S'wards to bring heavier rain across Scotland during the afternoon and evening. Thundery activity with hail in places affected the east and south Midlands, Norfolk, Suffolk and eventually the London area during the afternoon and early evening. N and W Scotland, and much of W Wales and Ireland had a rather dull day. It was cold in the wetter areas, and mostly rather cool elsewhere. (Pershore 19.3C, Banagher Caugh Hill 8.9C maximum, Libanus 3.8C minimum, Drumnadrochit 42.6 mm, Hawarden 8.9 h.)

A N'ly flow with several fronts continued to give unsettled weather on the 7th. There were spells of sunshine from SW Scotland through Wales to SE England, but it was rather dull elsewhere. Rain moved S'wards during the day, mainly in the E half of the UK, turning lighter as it did so. In SE England the rain turned showery; some of them were heavy with some thunder towards the SE coast. It was generally chilly, except in some of the brighter areas. (Wiggonholt 20.5C, Fair Isle 8.4C maximum, Shobdon 3.4C minimum, Fylingdales 16.4 mm, Guernsey Airport 11.8 h.)

The 8th dawned after a cool night in many parts of Scotland, with an air frost in parts of E and Cent Scotland. There was a little rain overnight in parts of England and Wales that moved away to the SE and most parts of the British Isles then had a dry day although there were some showers later in SW England, some of them heavy. E Ireland, W Wales and areas of N and E Scotland had a sunny day; elsewhere it was quite cloudy. (Hereford 20.0C, Fair Isle 9.5C maximum, Tulloch Bridge -1.9C minimum, Cardinham 17.4 mm, Stornoway 15.1 h.)

Although pressure remained generally high on the 9th, a warm sector spread across Ireland later in the day with rain spreading across here and Scotland into N England. Ahead of the associated cloud and rain, there was a ground frost in parts of E Britain, Wales and Northern Ireland. It was a sunny day in East Anglia, Kent and on Shetland. (Wisley 20.8C, Harris Quidnish 10.2C maximum, Redesdale Camp -0.5C minimum, Lough Fea 7.2 mm, Lerwick 15.9 h.)

The 10th was a rather cloudy day as rain spread slowly across all areas from the W. The best of the sunshine was to be found across N and W Scotland, with most other places remaining sunless during the day. Late in the afternoon and into the evening there was some heavy rain over S Wales, while a funnel cloud was spotted in the skies over Coventry, shortly before 1300 GMT. Following a night with minimum temperatures around 10C across much of Ireland, Wales and England, many places here struggled to reach 14-15C during the day. (Manston 17.5C, Inverbervie 10.0C maximum, Castlederg 5.6C minimum, Mumbles Head 49.0mm, Tiree 5.6 h.)

Low pressure centred close to Cornwall (centre 1005 mb) at 0000 GMT on the 11th moved slowly SE'wards during the morning, after giving a wet night across S Wales and SW England; 55 mm fell in the 12 hours ending 0600 GMT at Cardinham. Away from N and W Scotland, many places saw overnight rain, although during the day rainfall was generally confined to England and Wales and was light in most areas. It was a sunny day in Northern Ireland and W Scotland, but rather cloudy elsewhere feeling cool in an onshore wind in E Britain. Some rain moved W during the day across Norfolk, the N Midlands, N Wales and S Scotland from late morning, some of it getting into Northern Ireland in the evening. There was some thunder in along the coast in Cent S England in afternoon that moved W into SW England later. (Hurn 21.5C, Loftus 10.1C maximum, Fyvie Castle 3.5C minimum, Cardinham 49.8 mm, Tiree 12.5 h.)

Low pressure over Biscay on the 12th drew an E'ly flow across much of the British Isles. There was rain across N and Cent England overnight, with some heavy falls in E Yorkshire before dawn, with lesser falls over E Ireland and NW Scotland. During the afternoon and evening another band of rain spread N'wards across S and Cent England and into N England. With one or two exceptions (notably parts of W and NW Scotland), it was a generally cloudy day in all areas. Daytime temperatures in places N of The Wash overlooking the North Sea failed to reach 15C in the cool onshore wind. (Tyndrum 23.2C, Wick Airport 10.6C maximum, Braemar 2.4C minimum, Loftus 41.6 mm, Loch Glascarnoch 12.2 h.)

Low pressure centred close to, or over, the English Channel on the 13th continued to give an E'ly flow across most areas. Rain overnight in N England and S Ireland tended to move away N/NW-wards, with falls also in E Scotland. During the day the greatest falls, albeit mainly slight, tended to be across S and E Scotland as this rain area pushed away N'wards. The day was warm and humid, away from North Sea coastlines, and there were thundery outbreaks over the Channel Islands in the early afternoon, with further thunder in Kent by late afternoon. Further outbreaks then affected S Ireland, S Wales, the Midlands, SE England and N England, the storms tending to move W or NW and generally clearing by midnight - except over S Ireland where they persisted. The best of the sunshine tended to be in E England, to the S of the Humber. Further N, the E coast of Britain remained cloudy with mist and sea fog coming onshore. (Porthmadog 25.5C, Edinburgh Botanic Gardens 12.4C maximum, Exeter Airport 7.7C minimum, Chillingham Barns 14.0 mm, Wattisham 13.6 h.)

An E'ly flow on the 14th around an area of ow pressure close to Scilly (centre 1012 to the S of Ireland at 1200 GMT) produced bands of showers across England and Wales, with more general rain later moving off the North Sea into E Scotland. Many places, though, were dry with sunny spells. It was mostly quite warm, but some coastal areas were chilly, especially in parts of N Scotland, especially Shetland, where there was patchy sea fog. Away from Kent and East Anglia, it was quite dull close to the North Sea. (Santon Downham 25.5C, Loftus 13.3C maximum, Okehampton 6.9C minimum, Shawbury 31.0 mm, Stornoway 15.8 h.)

Low centres persisted over S areas of the British Isles on the 15th; resulting light winds overnight led to widespread patches of mist and fog by dawn over the British Isles. A few areas had showers overnight - notably from the SW Midlands into Wales. There were then sunny spells, but showers and thunderstorms developed over various parts of England, Wales and Ireland, and patchy rain moved across Scotland. It was quite warm, except near some coasts. A shop owner was left "devastated" by flooding on his first full day of trading after lockdown restrictions were eased. Dale Street in Milnrow, Rochdale was "completely flooded" when the River Beal rose rapidly in the evening. It was a dull day along the E coast of Scotland (away from the NE) and in NE England along the North Sea coast. A short funnel cloud was seen over Reading at 1729 GMT. (Astwood Bank 25.4C, Leuchars 13.2C maximum, Okehampton 6.3C minimum, Castlederg 48.2 mm, Lerwick 14.6 h.)

Overnight there was widespread patchy mist and fog into the 16th that soon cleared, except around some northern coasts. There were sunny intervals in most areas (away some parts of the E coast of Scotland and NE coast of England) but it was a showery day, and thunderstorms became rather widespread during the afternoon and well into the evening, especially over England (except the NE and Wales. There was flooding and lightning damage in various districts. Tornadoes were spotted across two counties - as parts of Wales were hit by thunderstorms. Eyewitnesses glimpsed the first just five miles north of Brecon in Powys late in the afternoon. Then 60 km away at Bont Goch, east of Talybont in Ceredigion, another twister was caught on camera. A house was set alight when it was struck by lightning as storms hit Sheffield; six people fled the three-storey building in Millhouses Lane as fire took hold in the roof in the evening. A house in Sutton Coldfield was set on fire at 1947 GMT after being struck by a lightning bolt as a storm battered the Midlands. The M6 northbound slip road at junction 10 for Walsall had to be closed. A number of roads in Birmingham and the Black Country became submerged in water including Percy Road in Sparkhill, the busy Washwood Heath Road in Ward End and the A449 in Dudley heading towards Kidderminster. Walsall Manor Hospital also suffered "severe flooding" in the heavy rain. Officials warned patients and staff that disruption would continue on Wednesday and urged them to take care when arriving at the building. (Heathrow 24.9C, Donna Nook 13.5C maximum, Whitechurch 7.0 mm, Market Bosworth 49.6 mm, Lerwick 13.1 h.)

In many places in the W half of the British Isles the 17th was a rather dull day. Much of England, Wales and S Scotland had some mist and fog patches before dawn, and this persisted during the day in some coastal areas. Many areas of England and Wales had NW'ward-moving thunderstorms from late morning onwards, that gave intense rainfall and flooding in places. Showers, with local thunder, also affected some W and NW areas, but much of NE England and Scotland had a dry day. A number of households have been forced to flee their homes after being flooded for the third time this year. Rhondda Cynon Taf council said there had been significant flooding to almost 200 properties in the borough after thunderstorms swept across Wales. South Wales Fire and Rescue Service said it spent five hours pumping water out of homes in Pentre, near Treorchy in the Rhondda valley. (Writtle 24.8C, Fair Isle 13.6C maximum, Lerwick 7.3C minimum, Sutton Bonington 40.6 mm, Morecambe 9.8 h.)

On the 18th a large area of often heavy rain moved west across England and Wales overnight and during the morning; there was thunder briefly over S Essex at the start and in the Southampton area around midday. The rain area was associated with a shallow low pressure system that lay across Cent Wales (1009 mb) by 1800 GMT. Mostly dry and quite sunny weather spread slowly from the SE from late morning; there were a few showers in places. By the evening, the rain was confined to S Scotland, Wales, Ireland and SW England. It was mostly rather cool, and decidedly chilly in the persistently wet areas. Much of Scotland had a sunny day, away from the NE and along the E coast. (Achnagart 24.5C, Pateley Bridge Ravens Nest 11.6C maximum, Aboyne 4.9C minimum, St Athan 50.0 mm, Altnaharra 13.4 h.)

There was a shallow low pressure area centred close to the Irish Sea for much of the 19th, which led to a rather cloudy and showery day over the British Isles. The best of any sunshine was to be found over parts of mainland N Scotland, where it was a warm day (following a cool night), and in parts of East Anglia and SE England. The largest rainfall totals overnight and during the day were over E Ireland and in W areas of England and Wales. (Altnaharra 22.2C, Lake Vyrnwy 12.0C maximum, Altnaharra 7.6C minimum, Salsburgh 26.6 mm, Manston 9.4 h.)

Low pressure to the W of Ireland on the 20th drew a mild, S'ly flow across most areas during the day. In any areas the overnight minimum temperatures were in the range 10-13C. There were some spells of rain and showers across parts of Scotland, in particular, overnight and during the morning. During the afternoon widespread rain and windy conditions spread across Ireland from the W, reaching the Midlands and extending over most W areas of the UK by midnight. Ahead of the rain many places had a sunny day - especially in East Anglia and in parts of Wales, E Scotland and SE England. (Heathrow 23.0C, Fair Isle 12.3C maximum, Katesbridge 5.2C minimum, Kinlochewe 21.2 mm, Shoeburyness 12.1 h.)

An area of frontal rain spread E'wards across all areas during the morning of the 21st, to be followed by showery conditions across Scotland and N England. It was a mild night in most areas, with the SE corner of England having a warm day and the best of the sunshine was to be found in S areas of the British Isles, particularly in the Channel Islands and S Ireland. Some of the showers turned thundery during the afternoon across S Scotland and NE Ireland, but more notably over parts of the NE Midlands and NE England in the later afternoon and evening, before they moved away to the E. (Heathrow 23.9C, Fair Isle 12.3C maximum, Aboyne 7.4C minimum, Whitechurch 23.4 mm, Guernsey Airport 13.2 h.)

While pressure remained high to the SE of the UK on the 22nd, a warm sector spread NE'wards over W areas to give some rainfall across Scotland, but mostly over Ireland. 17 mm fell at Valentia in the 12 hours ending 0600 GMT, and 17 mm of rain fell at Claremorris in the 12 hours ending 1800 GMT. By late evening there was rain falling in parts of N Scotland and N England. While many W and N areas of the British Isles had a cloudy day, it was very sunny over much of the Midlands, East Anglia, SE and Cent S England and the Channel Islands. (Heathrow 23.9C, Eskdalemuir 13.4C maximum, Aboyne 2.3C minimum, Eskdalemuir 17.2 mm, Shoeburyness 15.5 h.)

Frontal cloud gave an area of slow-moving rain across Ireland and Scotland for much of the 23rd, while most of England and wales remained largely dry. S of a line Shropshire-Humberside it was a sunny day, with daytime temperatures widely reaching 25C and above E of a line York-Exeter. The S'ly airflow also helped temperatures reach 20C as far N as N Scotland although parts of W Ireland failed to reach 15C. (Heathrow 28.6C, Fair Isle 13.3C maximum, Kinbrace 7.7C minimum, Eskdalemuir 22.8 mm, Wattisham 15.4 h.)

A slow-moving cold front gave falls on rain in N and W Scotland and across Ireland overnight into the 24th; these falls were heavy in parts of N Ireland. During the day there were further falls in places here but these were mainly sporadic and slight. To the E of this rain the day dawned after a mild night with overnight minimum temperatures above 15C in many places. During the day, England, Wales and SE Scotland had a sunny day with little cloud; most inland areas of England and Wales reached 25C, with 30C being reached in parts of Cent and S England. (Heathrow 32.6C, Harris Quidnish 14.5C maximum, Redesdale Camp 8.1C minimum, Port Ellen 15.2 mm, Morecambe 15.4 h.)

Away from W Scotland the 25th dawned after a mild night especially so over many parts of England and Wales where minimum temperatures remained above 15C; at St Catherine's Point the overnight minimum was 19.9C. A warm day followed in NE Ireland, Cent and E Scotland and across most of England and Wales. Temperatures inland reached 30C in many places as far N and SW Scotland. These warm areas were also, generally, sunny. Further W the day was cloudier. Thunderstorms over N Ireland around dawn spread N'wards into SW Scotland, and these then continued to move N'wards, with further outbreaks in W Scotland in the morning and afternoon. The later afternoon and evening brought more thundery outbreaks over the Channel Islands, SW England, Wales, SE Ireland and W Scotland. Heavy rain during thunderstorms caused damage in parts of the Highlands and Western Isles. The West Highland Line was closed between Fort William and Mallaig after a landslip under the track near Lochailort. On the Isle of Harris, a section of the Rhenigidale road was washed away near the Maaruig village junction. A lightning strike also caused damage to a road in Stornoway on the Isle of Lewis. (Heathrow 33.4C, Stornoway 14.7C maximum, Loch Glascarnoch 6.2C minimum, Port Ellen 20.6 mm, Wattisham 15.9 h.)

Overnight into the 26th thunderstorms moved N'wards across Ireland and in areas around the Irish Sea, with a separate outbreak affecting Kent and parts of Essex around dawn. During the afternoon there were further outbreaks over N Ireland and the Midlands, that moved N'wards the latter outbreak into SE Scotland after giving some falls of hail in Yorkshire. Parts of Yorkshire were pelted with hailstones 3-4 cm in diameter during thunderstorms. Photographs posted on social media showed people in Leeds and Sheffield cradling handfuls of the icy precipitation. Many areas had a mild night with overnight minimum temperatures remaining above 18C in parts of Cent England (18.5C in Pershore). However, away from East Anglia and SE England it was a rather cloudy day as fronts spread from the W, leading to instability and the thunderstorms. Many inland areas of England, way from the SW, again reached 25C or higher; 30C was reached in places around London and in East Anglia while parts of W Ireland struggled to attain 15C. (Kew Gardens 31.2C, Aberdaron 14.9C maximum, Braemar 7.4C minimum, Castlederg 40.6 mm, Reading University 14.1 h.)

Low pressure close to, or over, Ireland on the 27th (centre 993 mb near Malin Head at 1200 GMT) pushed a sequence of fronts across much of Ireland, Wales and England overnight and then over Scotland during the day. The rain tended to turn showery during the day and were rather sparse across parts of E England and N Scotland. Away from S Britain the showers turned thundery in laces. Much of the British Isles was generally rather cloudy except across parts of mainland N Scotland. As a result, the warmest conditions during the day occurred across parts of N Scotland. (Kinloss 26.5C, Capel Curig 14.6C maximum, Redesdale Camp 8.9C minimum, Sennybridge 24.0 mm, Stornoway 8.5 h.)

The 28th was generally chilly, blustery and showery, due to a slow-moving low centred just to the W of Scotland during the day. As a result, it was noticeably cold and wet over much of NW England, Ireland, SW and NW Scotland. Parts of S England and the Channel Islands had sunny spells. Honister Pass in the Lake District gave one of the wettest June days in the UK record for daily June rainfall - 212.8 mm of rain fell in the 24 hours from 0900 GMT; the heaviest known June fall in the UK was 243 mm at Bruton, Somerset on 28 June 1917. (Heathrow 22.0C, Blencathra 10.8C maximum, Okehampton 8.9C minimum, Kielder Castle 48.0 mm, Guernsey Airport 12.6 h.)

An area of low pressure pushed slowly E'wards across Scotland on the 29th, and numerous fronts associated with it meant that it continued chilly, blustery and showery, with further long outbreaks of rain overnight and at first over Scotland, N England, N Wales and the N half of Ireland in particular. There was some local thunder in the afternoon over E Scotland. The SE corner of England remained largely dry, although it was a cloudy day in all areas of the British Isles, with very few exceptions. (Heathrow 21.7C, Lake Vyrnwy 10.7C maximum, Dalwhinnie 8.4C minimum, Capel Curig 34.6 mm, Manston 8.7 h.)

While pressure rose slowly across Scotland on the 30th, by 1200 GMT another low centre was located close to Valentia, centred at 1003 mb. Fronts led to a day that was dull and cold, with widespread patchy rain and drizzle. There was widespread cloud, although it was brighter at times in isolated parts of SW and Cent Scotland. (Weybourne 21.9C, Ballypatrick Forest 13.1C maximum, Exeter Airport 9.5C, Ballypatrick Forest 9.8 mm, Tiree 10.5 h.)

British Isles weather, July 2020

A slow-moving area of low pressure, along with several fronts across the British Isles on the 1st, resulted in a rather cloudy and showery day. The best of the sunshine was to be found across W Scotland although in other areas the day was sunless in places. N Scotland and SW Britain were mostly dry in places. (Manston 22.8C, Dalwhinnie 10.3C maximum, Lerwick 6.7C minimum, Tyndrum 13.0 mm, Stornoway and Tiree 9.7 h.)

Overnight rain across N England into the 2nd turned showery and showers also affected most other areas of England during the day. There was some thunder over, chiefly, Essex and E Kent in the afternoon, whilst heavy showers continued to stream from the SE Midlands across London and N Kent into the evening; showers also affected Cent Scotland, while a further area of frontal rain spread across Ireland by mid-evening. There were sunny periods in most areas, but it was a rather dull day across much of NE England where it was also rather cool. (Heathrow 22.5C, Fylingdales 11.6C maximum, Altnaharra 0.3C minimum, Hull East Park 29.6 mm, Tiree 9.1 h.)

Areas of rain, heavy in places, swept across all areas from the W during the 3rd, although not until the evening did the rain reach Kent. There was a little sunshine across N Scotland while SE England was the sunniest area during the day; most areas were dull in the blustery conditions. Parts of N Wales were especially wet. (Heathrow 22.5C, Dalwhinnie 11.3C maximum, Braemar 6.3C minimum, Capel Curig 83.6 mm, Manston 10.4 h.)

The 4th was a generally cloudy day with areas of mainly light rain affecting most areas from time to time. It was a mainly cool day and windy in S Britain. Low pressure approaching W Ireland in the evening pushed an area of heavier rain into Ireland and Scotland as the low headed towards W Scotland. (Charsfield 21.7C, Tulloch Bridge 12.1C maximum, Braemar 3.0C minimum, Stonyhurst 29.8 mm, Bala 4.2 h.)

Low pressure pushed rain across many areas overnight into the 5th; there were some heavy falls across Scotland but amounts decreased as the rain spread S'wards. Much of E and Cent England had a mild night with overnight minimum temperatures above 17C in parts of East Anglia. It was mainly sunny in E areas of mainland UK, and across S England, with showers towards the W. There were some thundery outbreaks over N England in the afternoon. An historic hotel is counting the cost after being hit by floods as warnings were around Wales; by the Ty'n y Cornel Hotel, by Tal-y-llyn lake in Gwynedd, floodwaters were knee-deep on the road. (Manston 24.4C, Dalwhinnie 11.2C maximum, Loch Glascarnoch 8.0C minimum, Eskdalemuir 32.8 mm, Shoeburyness 12.3 h.)

The NW'ly surface airflow weakened as the 6th developed, but the flow direction meant a rather cool day. There were showers overnight across the N half of the British Isles, but these weakened and were less widespread during the day. In many areas it was a rather cloudy day. (Pershore 22.3C, Lerwick 11.1C maximum, Braemar 7.5C minimum, Myerscough 11.8 mm, Guernsey Airport 13.9 h.)

Overnight rain across parts of W Ireland and N and W Scotland into the 7th spread across much of S Scotland, N and Cent England and Wales during the day. S England remained largely dry with some sunshine, and there were also sunny intervals over many areas of Scotland once the rain had cleared away to showers. Later in the day a low pressure centre moved across Ireland and into N Wales. (Heathrow 22.6C, Fair Isle 11.5C maximum, Wick Airport 5.4C minimum, Gogerddan 21.6 mm, Jersey Airport 14.2 h.)

Frontal bands straddled many cent areas of the British Isles on the 8th. Low pressure centred over N Wales at 0000 GMT moved E'wards across the N Midlands towards the North Sea before midday while another low centre moved E'wards across Ireland in the evening to reach N wales by 2400 GMT. Rain spread across much of Wales and England overnight, and across Northern Ireland, Wales and England again during the afternoon and evening, with drizzly spells in between. There was little rainfall across N and Cent Scotland, nor across parts of the extreme S of England. The best of any sunshine was to be found in parts of Scotland with much of England, Wales and Ireland remaining dull. The hosepipe ban on the Isle of Man was lifted after days of heavy rain; the ban was introduced on 5 June following the driest spring on the island for 35 years. (Exeter Airport 20.8C, Emley Moor 12.5C maximum, Kinbrace -0.6C minimum, St Athan 32.8 mm, Tiree 11.7 h.)

A wave depression with several associated fronts affected much of England and Wales on the 9th. Across S England the day dawned after a warm night. It was rather dull across England and Wales as a result of the frontal cloud, but there were sunny spells across much of Ireland and Scotland after a cool night in parts of N and Cent Scotland. (South Farnborough and Writtle 20.8C, Emley Moor 11.0C maximum, Achnagart 2.9C minimum, Emley Moor 33.0 mm, Boulmer 11.3 h.)

The 10th was another cool day for some, with a NW'ly surface flow despite pressure rising to about 1026 mb over SW Ireland by mid-evening. There were falls of rain across Scotland, N England and E areas of the UK overnight, while there were further showers in these areas during the day, with local thunder over E England (especially Lincolnshire) in the afternoon. Most places had sunny spells during the day, especially over S Ireland, SW England, Wales and the Channel Islands. (Shoreham 21.2C, Dalwhinnie 12.8C maximum, Kinbrace 4.2C minimum, Spadeadam 16.8 mm, Guernsey Airport 14.4 h.)

High pressure on the 11th, initially centred S of Ireland and later S of Cornwall (1029 mb at 1800 GMT) drew a N'ly flow across most areas but led to a largely dry day. grass minimum temperatures fell to just above 0C across many parts of S and Cent England. There were a few showers across Scotland overnight and during the day, while it was a very sunny day across S Ireland, Wales and SW England. (Gosport Fleetlands 23.1C, Fair Isle 12.7C maximum, Benson 3.8C minimum, Loch Glascarnoch 4.0 mm, Aberdaron 14.6 h.)

Pressure remained largely high on the 12th but frontal cloud and rain spread across Ireland and W Scotland later in the day. It was mainly dry overnight with a ground frost in parts of Cent England; but, there was some light rain across N Scotland with also falls across many parts of Ireland by midday. Ich of England had a sunny day and it was warm in the London area. However, in W Ireland daytime maximum temperatures failed to reach 15C in places as 5 mm of rain fell at Belmullet in the 12 hours ending 1800 GMT. (Heathrow 25.2C, Fair Isle 13.4C maximum, Sennybridge 1.3C minimum, Harris Quidnish 5.4 mm, Guernsey Airport and Shoeburyness 14.9 h.)

Low pressure, moving E towards the Northern Isles on the 13th, pushed areas of frontal rain across all areas during the day. Ahead of the rain it was warm and sunny in S and SE areas of the UK minimum temperatures overnight were around 14-15C in a cloudy S Wales. Brighter, but showery conditions, followed the rain from the W. 17 mm of rain fell at Valentia in the 12 hours ending 0600 MT. (Shoeburyness 26.4C, Fair Isle 13.2C maximum, Goudhurst 6.5C minimum, Scolton Country Park 17.0 mm, Jersey Airport 13.0h.)

The 14th was a rather cloudy day. An area of rain cleared East Anglia and SE England before dawn, by which time a new area of rain had spread across W Ireland. This spread into Wales, W England and W Scotland by mid-evening and the cloudy skies led to rather cool conditions during the day maximum temperatures across much of Ireland failed to reach 15C by 1800 GMT. (Heathrow 23.1C, Banagher Caugh Hill 12.3C maximum, Topcliffe 7.4C minimum, Altnahinch Filters 124 mm, Leuchars 7.9 h.)

E'ward-moving fronts were slow-moving on the 15th, giving spells of mainly light rain to most areas. E areas of England were mainly dry before dawn, and there was only slight rain in S England during the day. Shetland, and parts of Kent and East Anglia had a little sunshine, but elsewhere it was mostly dull and cool. (Leuchars 21.0C, Giants Causeway 13.2C maximum, Houghton Hall 7.1C minimum, Altnahinch Filters 10.0mm, Manston 6.5 h.)

A ridge of high pressure covered the British Isles on the 16th, although the day was rather cloudy with frontal rain falling over parts of Ireland and Scotland. The day dawned after a warm night everywhere, with minimum temperatures above 15C overnight in Cent S and SE England. Despite the widespread cloud, it was a warm day in parts of England with maximum temperatures above 25C in parts of the Midlands and Cent S England. (Gosport Fleetlands 26.1C, Fair Isle 14.2C maximum, Threave 10.8C minimum, Achnagart 8.0 mm, Guernsey Airport 9.1 h.)

Ireland and S Scotland, in particular, had a dull day on the 17th as spells of rain moved E'wards across Scotland, Ireland and into N England. Following another mild night with overnight minimum temperatures remaining above 15C in places as far N as E Scotland, it was a warm day over East Anglia, the Midlands and Cent S and SE England. It was cooler across W Ireland and in N and W Scotland to the rear of the frontal rain. (Heathrow 28.5C, Ballypatrick Forest 13.7C maximum, Okehampton 9.0C minimum, Killylane 14.6 mm, Hurn 12.1 h.)

An area of rain pushed slowly SE'wards during the 18th, reaching the London area by the evening. England and Wales had a warm night with minimum temperatures widely exceeding 15C. Scotland, Ireland and the extreme N of England were sunny once the rain had cleared, although some showers followed the rain across NW Scotland. It was sunny and warm in SE England ahead of the rain. (Charlwood 26.4C, Dalwhinnie 14.3C maximum, Aboyne 3.8C minimum, Spadeadam 20.6 mm, East Malling 12.9 h.)

It was a wet night into the 19th over SW England, the Midlands and E England. Lighter rain and drizzle moved on into SE England during the morning and was slow to clear Kent. Pressure rose behind the rain (to 1023 mb in SW Ireland at 1800 GMT) although there were some showers in parts of Scotland. It was a sunny day in Ireland, Wales and W areas of England. (Pershore 22.3C, Dalwhinnie 13.6C maximum, Katesbridge 1.4C minimum, Holbeach 19.0 mm, Morecambe 14.6 h.)

High pressure centred to the SW of Ireland on the 20th led to a mainly dry day, except across N areas of Scotland where there were some showery falls. Many areas of N Ireland, N England and Scotland (except Shetland) were rather cloudy. (Gosport Fleetlands 24.4C, Wick Airport 13.4C, Sennybridge 2.3C minimum, Achnagart 11.2 mm, Guernsey Airport 15.0 h.)

High pressure led to a largely dry and sunny day in many areas especially in the S half of the British Isles on the 21st. Clear skies led to some early ground frost in parts of the Midlands. There was some overnight rain across N areas of Scotland that continued to fall in places during the day. Later in the afternoon a more general area of rain pushed into W Scotland and N Ireland. (Gosport Fleetlands 24.7C, Fair Isle 13.8C maximum, Sennybridge 2.2C minimum, Wick Airport 8.0 mm, Guernsey Airport 14.8 h.)

The 22nd was a sunny day on Shetland and in S England, but rather dull in Cent and S Scotland, N Ireland and N England as areas of rain spread across these areas and other parts of Ireland. The rain was followed by showery conditions. Daytime temperatures reached 25C in the Greater London area. (Heathrow 26.3C, Inverbervie 12.1C maximum, Aboyne 3.9C minimum, Dunstaffnage 28.2 mm, Lerwick 15.0 h.)

A low pressure system that moved E'wards across N Scotland on the 23rd, and associated fronts that slowly moved SE'wards, brought widespread rainfall across Ireland, S Scotland, N Wales and N England overnight. Associated and widespread cloud let to a mostly mild night across the British Isles. The day was a mainly cloudy one although SE England and parts of East Anglia remained largely dry and had the best of the sunshine, as did areas of S Ireland. Despite the increasing cloud, it was a warm day in parts of East Anglia and SE England. (Northolt 26.6C, Ballypatrick Forest 14.0C maximum, Frittenden 8.6C minimum, Dundrennan 40.4 mm, Cork Airport 10.9 h.)

The 24th dawned after a cloudy night across England and Wales that led to some light falls of rain here; elsewhere the night was largely dry. Another area of rain associated with an arriving warm sector cross Ireland and spread into W and S Scotland and the W half of England by late evening. As a result of the approaching rain the best of the sunshine was to be found in E areas of the UK while the warmest air was to be found in E England. (Kew Gardens 25.9C, Tiree 14.3C maximum, Braemar 4.0C minimum, Port Ellen 13.6 mm, Lerwick 10.3 h.)

The warm sector moved away from E England later on the 25th, after a generally cloudy day and one that gave spells of rain to most areas. It was a mild night in all areas ahead of the clearing cold front. These spells were thundery at times moving in a NE'ly direction associated with troughs behind a cold front that led to the earlier rain. These were most notable over the Midlands after about 1700 h these storms headed towards Lincolnshire by about 2000 GMT. A tornado caused damage at Northampton. In parts of the Midlands and S England there were localised, heavy showers in the evening. (Coningsby 25.6C, Fair Isle 13.1C maximum, Baltasound 10.6C minimum, Craibstone 35.6 mm, Leuchars 5.6 h.)

The 26th was a day with sunny spells in most areas. A low pressure area close to NW Scotland pushed some rain into W Scotland and W Ireland around dawn and this moved E'wards, weakening in intensity as the day developed.

(Teddington Bushy Park 24.2C, Harris Quidnish 14.0C maximum, Katesbridge 7.8C minimum, Harris Quidnish 10.6 mm, Tiree 9.6 h.)

An area of low pressure moved NE'wards from SW Ireland to NE Scotland during the 27th. Areas of rain were widespread (from S Scotland S'wards) before dawn and steadily moved away to the NE, becoming confined to N and Cent Scotland by the evening. The day dawned after a warm night across England and Wales with minimum temperatures above 15C in parts of E and S England. S Scotland and S England remained mostly cloudy during the day; elsewhere there were some sunny intervals after the rain cleared away, while N Scotland had some sunshine ahead of the rain. (Pershore 22.9C, Dalwhinnie 10.7C maximum, Fyvie Castle 4.1C minimum, Shap 35.8 mm, Cork Airport 7.3 h.)

Weather on the 28th was dominated by NW'ly winds due to a slow-moving area of low pressure to the E of Scotland. The day followed a mild night in S England; rain affected mainly Scotland overnight but there were some light falls in East Anglia, N England and in parts of Ireland. Overnight rain in the Northern Isles was heavy at times. It was rather cloudy at times in many areas, and quite dull over the Northern Isles; during the day there were light falls of rain across Scotland, N Ireland and N England. (Shoreham 23.0C, Loch Glascarnoch 11.5C maximum, Killylane 7.9C minimum, Fair Isle 24.0 mm, Guernsey Airport 13.4 h.)

Frontal cloud and some rain affected N Scotland overnight into the 29th while an advancing depression pushed some rain NE'wards into SW Ireland by dawn.

(Heathrow 24.5C, Lerwick 10.7C maximum, Exeter Airport 4.5C minimum, Resallach 10.0 mm, Jersey Airport 13.8 h.)

A warm S'ly flow from the near-continent on the 30th led to a hot day over most if England (but not N England) and E Wales, where it was also very sunny with little cloud in much of S England. An area of low pressure to the W of Ireland spread rain across Ireland, S Scotland, N Wales and N England before dawn this rain pushed N'wards into N Scotland during the day. 44 mm of rain fell in Valentia in the 12 hours ending 0600 GMT. (St Helier, Jersey 29.9C, Lerwick 12.3C maximum, Tulloch Bridge 2.0C minimum, Dundrennan 17.4 mm, Wattisham 14.9 h.)

They were above 17C in parts of S England and 19.5C at Guernsey Airport and Jersey Airport with 20.7 at Jersey St Helier. It was a dry night except in W Ireland where a cold front spread rain from the W across W Ireland by dawn. During the day E and Cent districts of the UK were mostly sunny and very hot, but also increasingly windy, before cloud and patchy rain spread across from the W during the afternoon and evening. Thunderstorms affected Northern Ireland briefly in the early afternoon, SW Scotland in the late afternoon and early evening, and the NE Midlands and Yorkshire in the evening. Clearer, much cooler weather spread to much of the west and south by the evening. (Heathrow 37.8C, Fair Isle 14.6C maximum, Shobdon 8.3C minimum, Ryhill 10.8 mm, Weybourne 13.5 h.)

It was a mild night everywhere with minimum temperatures of 15C as far N as the Grampians and of 20C in Cent S and SE England (21.7C at Heathrow). The storms cleared E Scotland by mid-morning, while in the afternoon there were further thundery outbreaks over Wales, Cumbria and Cent S England this latter area of storms moved towards Wales and then N'wards. It was a hot day across the UK with 25C as far N as Cent Scotland and 33C widely reported over the Midlands, East Anglia and Cent S and SE England. Most places had a mix of cloud and sunny spells but it was rather cloudy over SW England, E Ireland, the Channel Islands and N Scotland. Emergency services said 28 people were rescued after a landslide at Pettycur Bay Holiday Park. A number of homes were also flooded and many schools in the area closed as a result. Stonehaven in Aberdeenshire was affected by flooding after the storms. A major incident was declared in Fife after torrential rain and thunderstorms affected many parts of Cent and E Scotland; three died when a passenger train derailed after hitting a landslip near Stonehaven. The incident sparked a major response from emergency services, with about 30 vehicles - including air ambulance support - called to the scene at 0843 GMT. Later in the day lightning struck a house in Wrexham, blowing out power sockets and setting fire to a curtain. Heavy rain also caused flooding in Rhayader, Powys. Torrential rain and thunderstorms also created a 30 metre-wide hole in the Union canal. Aerial images show part of the canal's embankment near Polmont was washed away severe weather. The breach has flooded Scotland's busiest railway line - between Edinburgh and Glasgow - resulting in its closure. There was a big hailstorm in SW London, hitting areas like Richmond, Twickenham and Mortlake it brought hailstones the size of ice cubes down. Today saw the UK having its longest stretch (six says) of temperatures exceeding 34C since such records began in the 1960s. However, the 16-day heatwave from 23 June to 8 July 1976 saw temperatures reach 30C or more somewhere each day. (Heathrow 35.4C, Giants Causeway 13.8C maximum, Magilligan 10.7C minimum, Inverbervie 54.6 mm, Hurn 13.0 h.)

The 13th dawned after a mild to very warm night everywhere. Overnight minimum temperatures included 21.3C at Heathrow, 20.1C at Middle Wallop while minima of 17-20C were reported across many areas of England and Wales; the coldest place (Harris Quidnish) had a minimum temperature of 11.2C. Thundery showers slowly died away overnight, although there was still patchy rain, especially in the S half of England and Wales. Patches of mist and fog were widespread across Ireland, E Scotland and England by dawn; it was persistent through the day along stretches of the North Yorkshire coast. Places from N Wales to SW Scotland had a sunny day, but elsewhere it was rather cloudy. Numerous thundery showers affected the S Britain, with violent storms, torrential rain and hail in various districts, especially Cambridgeshire, the SW moors and the North Downs. The M25 was partially closed in both directions around 1600 GMT between J7 and J8 near Reigate due to flooding caused by a sudden heavy downpour. (Porthmadog 29.8C, Lerwick 14.1C maximum, Harris Quidnish 11.2C minimum, Newport (Salop) 38.8 mm, Morecambe 12.7 h.)

Into the 14th minimum temperatures were widely above 15C across England (except in NW England), Wales and the Republic of Ireland. There was rain in places overnight across S areas of England, Wales and Ireland that was thundery in places. During the day further falls of rain were largely confined to counties in NE, E and S England. There was an outbreak of heavy rain over parts of North Yorkshire in the morning. Much of the rain was light, but there were some heavier bursts - and there was thunder in a few districts, especially over East Anglia in the morning and mid-afternoon. The wet areas were generally dull throughout the day, with the best of the sunshine being across SW Scotland, NW England and in parts of Northern Ireland. (Coton-In-The-Elms 26.5C, Lerwick 13.0C maximum, Lerwick 9.7C minimum, Cavendish 49.2 mm, Ronaldsway 13.1 h.)

Many areas of E, S and Cent England, Wales and S Ireland had a warm night with overnight minimum temperatures above 15C on the 15th. There was some overnight rain across parts of S England, with thundery showers in SW Ireland before dawn; 27 mm of rain fell at Valentia in the 12 hours ending 0600 GMT. Further thunderstorms affected Cent and SW Ireland late in the afternoon. Most of Scotland, Cent and N Ireland and NW England were dry with sunny spells, although it was cloudy near many E coasts. Most of England and Wales was dull and there were areas of rain and drizzle. Heavy rain fell in places, especially as a cold front edged NE'wards over N Kent, London and Essex; in particular, a thunderstorm gave 40 mm of rain during 1500-1600 GMT at Writtle, whilst there was a narrow zone of very heavy rain from SW Essex into Cent London after sunset. Two kayakers were able to paddle their way down a street in Chelmsford after heavy rainfall caused flash flooding in the late afternoon; Essex Police said it was called to a small number of flooding incidents. (Porthmadog 25.3C, Fylingdales 14.5C maximum, Stornoway 6.3C minimum, Writtle 53.6 mm, Valley 12.1 h.)

On the 16th most places in England, Wales and S Ireland dawned after a mild night, with overnight minimum temperatures of 19.0C in Shoeburyness and 18.9C at Northolt. Over Scotland, Northern Ireland and northern England the day was mainly cloudy with a few showery outbreaks with the sunniest places being in mainland N Scotland. An area of occasionally heavy, cold-frontal, rain moved slowly north over S England, with local thunder in Kent in the early afternoon. It weakened as it moved N'wards, in the wake of widespread heavy showers that developed over E and Cent England across to S Wales; there were violent thunderstorms in the afternoon and evening across East Anglia, Lincolnshire, the E and S Midlands and S Wales. Thundery showers also occurred from SE Wales to London in the evening (12.6 mm fell at St James's Park in one hour). An impressive waterspout was spotted in the Bristol Channel in the afternoon, which could be seen from over a large area. Roads turned into rivers in a Northamptonshire town after it was struck by heavy rain; videos shared on social media showed cars struggling through deep water in Wellingborough while Northamptonshire Fire and Rescue Service received more than 60 calls in connection with flooding in the county. A couple had to evacuate their home in Watton (Norfolk) and dozens more were affected by flooding as heavy rain caused havoc around Norfolk; Norfolk Fire and Rescue were inundated with calls in Watton and villages nearby, with 27 callouts between 1400 GMT and 1830 GMT. Earlier in the day, torrential rain hit Sheringham resulting in homes being flooded and main roads closed. Norfolk Fire and Rescue also responded to six callouts around Harling, six in Saham Toney and two in Great Hocking. (Cavendish 25.9C, Lerwick 13.7C maximum, Kinbrace 5.0C minimum, Cranwell 42.0 mm, Altnaharra 11.2 h.)

Overnight into the 17th a large area of rain emanating from Sunday's storms drifted slowly NW'wards across Wales, SE Ireland, N England, Northern Ireland and Scotland. It slowly weakened in N areas during the day, but there was heavy rain as it wound its way back over Ireland and Wales into SW England. Elsewhere, after patchy fog, showers around the Isle of Wight early in the day moved inland and showers and thunderstorms became widespread across many areas of England from late morning until early evening. The best of the sunshine was to be found in East Anglia, SE England and the Channel Islands many areas remained cloudy all day. Heavy rain during late morning in Loughton, Essex, led to flooded roads here. (Heathrow 25.1C, Altnahinch Filters 13.5C maximum, Aboyne 8.0C minimum, Wellesbourne 49.0 mm, Guernsey Airport 9.8 h.)

A low pressure centre over the Irish Sea on the 18th (centre 1003 mb at 0000 GMT) filled but an unsettled, showery day followed in all areas. Rain over Cent Ireland and Wales at first then moved towards SW Scotland. There was some thunder in S England in the morning, and then during the afternoon in other S and Cent areas of England, and in N Scotland. After a generally warm night in all areas, daytime temperatures reached 23C as far N as mainland N Scotland although it was a dull day across many areas of Scotland due to the advancing rain, while fog was persistent around the Northern Isles. (Manston 25.6C, Fair Isle 15.0C maximum, Bainbridge 9.9C minimum, Porthmadog 25.4 mm, Shoeburyness 11.8 h.)

Storm Ellen was the driver of the weather on the later on the 19th. Rain spread across Ireland, Wales, England and S Scotland; there was some heavy rain, especially in the S, but wherever there were drier interludes it was quite warm. Most of Scotland, and for much of the day northernmost England, was dry and, locally, warm with some sunshine. Athenry, Co Galway recorded a MSL Pressure of 966.4 mb at 2400 GMT; this is the lowest MSL pressure on record for Ireland in August. The previous record was 967.8 mb at Belmullet on the 14 August 1959. A combination of storm surge, spring tides and onshore winds caused some coastal flooding particularly along the south coast of Ireland. SE'ly strong gale force 9 to storm force 10 winds occasionally reached violent storm force 11 as the storm centre approached the south coast of Ireland. The combination of unseasonal heavy rainfall and strong winds coinciding with trees in full leaf and the peak holiday season resulted in impacts more associated with late autumn or winter. Roches Point (Cork) reported a mean wind speed of 60 kn at 2200 GMT, the highest on record there for August. The maximum gust of 77 kn at Roches point was the second highest on record in Ireland in August (after 78 kn at Claremorris on 11 August 1999). Several parts of Cork saw flooding, including Skibbereen, Kinsale, Middleton and Bantry, while waves spilled over the seafront wall at Youghal. Skibbereen experienced heavy flooding in the town centre after intense rainfall. The Republic of Ireland's electricity operator, ESB Networks, said gale force winds had caused significant and widespread damage to the electricity network, "affecting more than 194,000 homes, farms and businesses". (Achnagart 24.7C, Wick Airport 16.2C maximum, Braemar 6.6C minimum, Hurn 35.8 mm, Stornoway 10.0 h.)

Pressure remained very low to the W of Ireland on the 20th. Rain cleared E'wards overnight; for a time, temperatures were higher than during the day in parts of the southeast - it was 21.2C at St James's Park at 0100 GMT. It was a sunny day in the E half of England and the Channel Islands with the heaviest rain falling further to the W during the day. There was some thunder over Ireland and parts of S England in the morning and across parts of Northern Ireland and SW Scotland in the late afternoon and evening. Further thunder occurred in S Ireland, SW England and S Wales in the evening. Northern Ireland escaped the worst of storm Ellen, but high winds and heavy rain caused damage in southern parts of the island. Several roads across Northern Ireland were blocked by fallen trees, with 99 households affected by power cuts as of 2000 GMT, TrafficwatchNI reported fallen trees in all six counties in Northern Ireland, with County Fermanagh worst affected. Southern, western and midland counties in the Republic of Ireland bore the brunt of the storm, but County Cork saw the strongest winds and coastal flooding. In County Fermanagh, six people were rescued from two boats at Devenish Island when the vessels began breaking their moorings in the early hours of the morning. (Weybourne 27.3C, Killylane 16.7C maximum, Westonbirt 10.8C minimum, Thomastown 30.6 mm, Waddington 12.8 h.)

The effects of storm Ellen continued to be felt on the 21st as the low centre moved from near Belmullet (975 mb at 0600 GMT) to Orkney (985 mb at 1800 GMT). The day followed a warm night everywhere with minimum temperatures around 17C in parts of East Anglia and S England. The NE corner of Scotland along with East Anglia and SE England avoided rainfall overnight, which was heavy in parts of Wales. The day was rather cloudy for many with further widespread falls of rain and showers, although the SE corner of England largely avoided the precipitation. In the evening and overnight, a line of iconic beach huts were swept out to sea as storm Ellen battered the Welsh coastline. Gales brought by storm Ellen led to the cancellation of ferry crossings between the Isle of Man and England during the day. Huge waves, driven by 70mph winds, hit the Llyn Peninsula. Hundreds of homes were left without power in south Wales, seven flood warnings were issued and there was significant disruption to travel. Gusts of up to 95 mph forced the closure of the M48 Severn Bridge, and a 30mph speed limit was in place on the A55 Britannia Bridge. Western Power Distribution said it had reconnected homes in Caerphilly county, Monmouthshire and Vale of Glamorgan after power cuts on Friday. Rail services on the Cambrian line between Pwllheli and Machynlleth have been affected and replacement buses were being arranged. Earlier, trains between Holyhead and Bangor were running at reduced speed due to "severe weather". Ferry services between Holyhead and Dublin, and Fishguard and Rosslare were cancelled or delayed. (Weybourne 24.8C, Eskdalemuir 15.4C maximum, Aberporth 11.1C minimum, Bala 38.2 mm, Weybourne 9.3 h.)

Low pressure centres over Ireland and to the N of Scotland continued to dominate the weather on the 22nd. Windy conditions helped to produce another mild night in all areas and there were widespread outbreaks of rain and showers overnight. Further falls continued during the day, especially across N England, S Scotland and N Ireland. Most places had some sunny spells, especially East Anglia and S England. In a few places in S and E England the showers turned thundery. (Heathrow 24.4C, Fair Isle 12.8C maximum, Aboyne 10.4C minimum, Stonyhurst 43.6 mm, Wattisham 9.6 h.)

Winds continued to ease on the 23rd as a weak NW'ly flow became established. Parts of England and Wales had another warm night with minimum temperatures above 15C in places, although many areas of the British Isles had some light to moderate showery falls. A rather cloudy day followed with further widespread showers; these were heaviest across N Ireland, N England and S Scotland. There was thunder over the NE Midlands and Lincolnshire in the afternoon. (Heathrow 23.6C, Loch Glascarnoch 11.4C maximum, Drumnadrochit 7.6C minimum, Carlisle 28.0 mm, Jersey Airport 8.3 h.)

A rather cloudy, weak ridge of high pressure affected most areas on the 24th. It was a cold night in mainland N Scotland with a slight air frost and a widespread ground frost here. Overnight rain over N England moved away NE'wards in S Scotland and over the North Sea, while another area of rain spread NE'wards across SW England and into the S Midlands. This latter area gave some rain across S areas of England and Wales before weakening and there was also some light rain across N Scotland during the day. Many parts of N England, S Scotland and NE Scotland had a sunny day; elsewhere there were cloudy skies and sunny periods. In the evening rain spread across Ireland and into Wales and SW England, ahead of a deepening area of low pressure. (Manston 24.1C, Lerwick 13.5C maximum, Loch Glascarnoch -0.4C minimum, St Catherines' Point 31.4 mm, Morecambe 12.6 h.)

The centre of storm Francis moved slowly NE'wards across Ireland and N England on the 25th, centred at 979 mb over W Ireland at 0600 GMT and N of Dublin at 1200 GMT. Overnight and during the day a large area of, at times heavy, rain moved from Ireland and SW Britain into N Ireland and Scotland, with showers following to the south of the main rain area. After a mild night over Ireland, Wales and much of England it was a windy day at times in all areas. It was also rather dull and cloudy in most places. As of 1200 GMT, wind gusts of 78 mph had been recorded at the Needles and 63 mph at Mumbles. Several places in England and Wales have provisionally recorded their highest ever gusts of wind in August - including 68 mph at Pembrey Sands, 52 mph at Shobdon and 49 mph at Pershore. Homes have been flooded, campers rescued, and road and rail travel disrupted amid the severe weather. Plymouth, on the south Devon coast, also recorded gusts of 53 mph in the morning. An Environment Agency recording taken overnight on Tuesday logged 65.8 mm of rainfall at White Barrow in Devon. There was flooding in parts of Wales early on Tuesday. Fire crews rescued nine people and two dogs from a flooded campsite in St Clears, Carmarthenshire, after river levels rose. A number of homes in Neath, Whitland, Tonyrefail and Llanelli were hit by flooding, while flash floods submerged roads across the country. Heavy downpours have also caused disruption across Northern Ireland, where motorists were urged to seek alternative routes after the Shimna River burst its banks in County Down. Network Rail said speed restrictions were in place on several rail routes across the UK. Avanti West Coast, Northern, TransPennine Express and Transport for Wales are currently disrupted due to weather related issues, it said. The M48 Severn Bridge was closed in both directions between junctions 1 and 2 due to strong winds in the area. Elsewhere, the Highways Agency reported a fallen tree temporarily blocking the A30 in Cornwall, while another toppled tree brought disruption by blocking the rail line between Gunnislake in Cornwall and Plymouth in Devon, before being cleared. Bantry in west Cork saw up to 50 businesses incurred flood damage overnight. The local main drainage scheme was unable to cope with up to 25 mm of rain falling in a two hour period. Flooding also occurred at Dunmanway, Rosscarbery, Connonagh, Clonakilty, Drimoleague, Leap, Ballydehob, Passage West and Youghal. Fallen trees and local flooding blocked roads in counties Clare, Kerry, Wexford, Cork, Kilkenny, Laois, Tipperary and Meath. Electricity outages left hundreds of premises without power, with Cork, Limerick, Tipperary and Galway worst affected. Natural Resources Wales' Beddgelert monitoring station showed the River Glaslyn was at its highest level ever recorded on Tuesday. (Heathrow 22.4C, Dalwhinnie 11.8C maximum, Altnaharra 4.1C minimum, Lake Vyrnwy 68.4 mm, Lerwick 10.0 h.)

The winds eased from the W during the morning as Storm Francis continued to move E'wards on the 26th, and pressure rose from the SW. Rain across Scotland and N England moved slowly away E'wards during the day, following a wet night across N Ireland, S Scotland and N England. Most places had a mild night with minimum temperatures around 16C in arts of S England. Rainfall figures between 2200 GMT/24th 0500 GMT today show that 95.2 mm fell at Middlefell Farm in Mickleden (Cumbria). In the same period Bethesda Quarry in N Wales recorded 104 mm. During the day there were showers in places, but much of Cent and S Ireland, Wales and Cent and S England remained dry. It was rather cloudy in many areas, but there were long, sunny spells in parts of S England. Dozens of people were evacuated from their homes overnight and there was widespread travel disruption after Wales was hit by storm Francis. In total, there were 80 evacuations and rescues across north Wales overnight. A number of rivers burst their banks, requiring evacuation of properties in the Bethesda and Beddgelert areas. A landslip closed the A5 between Bethesda and Betws y Coed. In Bethesda about 40 people were rescued from chalets and homes and taken to the local leisure centre. About five Beddgelert householders were also rescued by boat, the fire and rescue service said. (Heathrow 23.6C, Fair Isle 11.6C maximum, Kinbrace 7.2C minimum, Leek 19.6 mm, Camborne 11.0 h.)

A complex area of low pressure (centres at 1200 GMT of 1005 mb over S Ireland and 1005 mb just S of Cornwall) on the 27th led to an unsettled day in many areas. Overnight, areas of rain spread over Ireland and into Cornwall and W and S Scotland. During the day the rain spread across most areas with heavy, thundery falls across S England and S Ireland in the afternoon. There were also thundery outbreaks earlier over parts of N England and S Scotland. The Northern Isles remained largely dry during the day, with the best of any sunshine here and on the Channel Islands. Emergency crews were called out to rescue people from their homes in Broxburn after severe flooding in West Lothian. Firefighters used boats to take people out of flooded houses. Many cars in the town were also stranded up to their roofs in water. ScotRail warned that services across the country would be delayed or cancelled due to "extremely heavy rain flooding". Floodwater also closed some roads in the east end of Glasgow. A landslip blocked the railway line between Micheldever and Winchester in Hampshire after heavy rainfall here. Flooding caused damage to shops and pavements as Winchester was deluged by heavy rain. Trains between Winchester and Micheldever have been diverted after a landslip blocked all rail lines. Heavy rainfall caused widespread flooding across Devon and Cornwall. Plymouth Highways was forced to close multiple roads because of flash flooding, caused by rain described as "biblical" by the city's council. In Cornwall, floods forced road and railway closures, traffic jams and delays on train services. Devon and Somerset Fire Service said it had received reports of flooded properties in Devon, with most calls in Torquay and Paignton. (Manston 21.7C, Lake Vyrnwy 11.5C maximum, Kinlochewe 4.6C minimum, Camborne 36.8 mm, Kirkwall 4.2 h.)

Pressure slowly rose on the 28th as storm Francis and associated fronts moved away E'wards from the UK. Overnight there was some heavy rain across S Scotland, N England and N Wales with falls in many other areas. Further showers affected many areas of Ireland, Wales and England during the day, with falls also in E Scotland. These showers turned thundery across parts of S England, S Wales and East Anglia in the afternoon. It was cloudy in most areas with the best of the sunshine being in W areas of Ireland and Scotland. In many areas across the British Isles daytime temperatures failed to reach 17C. (Frittenden 21.0C, Fylingdales 11.6C maximum, Kinbrace 5.0C minimum, Scarborough 49.0 mm, Tiree 9.9 h.)

On the 29th much of eastern Britain was cold, grey and breezy with rain or drizzle, especially over E England from where it later extended further to the W and S after a bright start here. The cold conditions were, at least in part, due to the N'ly wind that prevailed. Most western regions had sunny spells. It was chilly nearly everywhere, and decidedly cold in some eastern districts where it was the locally the coldest August day in the last 100 years. (Gosport Fleetlands 18.9C, Balmoral 10.4C, maximum, Swyddffynnon 3.4C minimum, Tibenham Airfield 17.2 mm, St Athan 9.8 h.)

Pressure rose from the W during the day, with rising above 1020 mb in most places by late evening on the 30th. As a result, most places were dry during the day, after some overnight rain in parts of E Britain and East Anglia edged away E'wards. Most places were cool and rather cloudy with the best of the sunshine across Wales and S England. (Plymouth 19.5C, Fair Isle 12.5C maximum, Katesbridge -0.1C minimum, Monks Wood 4.6 mm, Bude 11.8 h.)

High pressure led to a generally dry day on the 31st, after a cool start across parts of N Scotland, SE Scotland and N England. The best of the sunshine was to be found around SW England and Wales, and also in the Northern Isles. However, many areas had a cloudy day and it was also rather cool. (Cardiff Bute Park 19.9C, Dalwhinnie 13.1C maximum, Altnaharra 0.2C minimum, Market Bosworth 0.6 mm, Lerwick 13.1 h.)

British Isles weather, September 2020

Despite high pressure over E areas of the UK on the 1st, frontal cloud gave rain to parts of W Ireland and W Scotland before dawn, with further falls across W Scotland and many areas of Ireland during the day. After some early mist in parts of S England and a slight ground in parts of N and E Scotland, most of Wales, England and E Scotland had a sunny day. (Kinlochewe 21.6C, Harris Quidnish 13.6C maximum, Braemar 0.2C minimum, South Uist 10.2 mm, Guernsey Airport 12.6 h.)

Frontal rain spread E'wards across all areas on the 2nd. There was a bright start to the day across E, and parts of Cent, areas of England, before the rain arrived. The rain was heavy over parts of Wales, Ireland, NW England and S Scotland and many of these areas were also rather cool. (Cambridge NIAB and St Helier 21.7C, Inverbervie 13.4C maximum, Santon Downham 3.6C minimum, Dundrennan 49.4 mm, Jersey Airport 9.4 h.)

The 3rd dawned after a warm night with minimum temperatures remaining above 15C overnight in many parts of Wales, the Midlands and S England. Much of S England and the S half of East Anglia remained dull as patchy rain spread E'wards. There were also showery falls across many parts of Scotland, Ireland and N England during the day. (Manston 23.2C, Fair Isle 14.3C maximum, Aboyne 7.4C minimum, Sennybridge 21.4 mm, Kinloss 9.3 h.)

An area of low pressure to the N of Scotland on the 4th produced bands of rain and showers that spread S'wards at times during the day. SW England and S Wales had a rather dull day elsewhere there were some sunny intervals. By early evening a line of rain, heavy in the SW, had formed from Cornwall to Norfolk. (Manston 22.0C, Dalwhinnie 12.9C maximum, Eskdalemuir 7.8C minimum, Achnagart 29.0 mm, Leuchars 9.5 h.)

A weak ridge on the 5th led to sunny spells in many areas, especially across S England. However, it was a dull day across N Ireland and SW Scotland. Rain cleared SE England early in the morning, while there were showers across Scotland and Ireland, and in parts of N England. It was generally a cool day. (Frittenden 20.8C, Lerwick 10.9C maximum, Exeter Airport 5.4C minimum, Keswick 11.6 mm, Guernsey Airport 10.8 h.)

It was a warm night across Ireland, SW Scotland and the W extraneities of England and Wales into the 6th. During the day across England and Wales there was some sunshine but also showers, although the SE stayed dry. After a bright start, cloud spread across Scotland and Ireland, with some rain later. Temperatures were near or rather below normal. (Cavendish 20.8C, Lerwick 11.2C maximum, Kinbrace 0.8C minimum, Blencathra 12.6 mm, Shoeburyness 8.0 h.)

An Icelandic low pressure system pushed fronts across much of the British isles on the 7th. By dawn there was widespread mist over much of England, with some fog patches, but widespread rain across Ireland and Scotland. There was some sunshine at first across S England ahead of the frontal cloud; elsewhere it was a mainly cloudy day with spells of rain mainly in the N and W. (Heathrow 21,9C, Lerwick 13.2C maximum, Sennybridge 5.9C minimum, Tiree 31.8 mm, Jersey Airport 8.0 h.)

The 8th followed a mild night everywhere, with overnight minimum temperatures remaining above 15C widely across England, Wales and Ireland. The heaviest overnight rain was mainly confined to Ireland and Wales, spreading into Scotland during the day. There was another area of heavy rain that affected N areas of Scotland into the evening. The best of the sunshine was to be found in some E areas of Scotland and in parts of NE England and also in parts of S England. It was very warm in East Anglia and in parts of SE England. (Cavendish 26.1C, Lerwick 13.1C maximum, Tain Range 9.8C minimum, Achnagart 23.0 mm, Jersey Airport 11.0 h.)

A cold front pushed SE'wards across all areas on the 9th, clearing SE England in the evening. England and Wales had a warm night with minimum temperatures widely above 15C, while it was cooler with some rain further W and N. As the front brought patchy rain to most areas of England and Wales the temperature fell; there were longer periods of sunshine to the rear of the front along with some showers over N and W Scotland. (Frittenden 25.0C, Lerwick 12.5C maximum, Katesbridge 5.8C minimum, Kirkwall 12.0 mm, Leeming 10.4 h.)

It was a mild night into the 10th over Ireland and Wales, but cool across Scotland with a ground frost in places. E, S and Cent England had a sunny day under high pressure. Elsewhere, it clouded over from the NW, with rain later over parts of Ireland, W and N Scotland. (Herstmonceux 21.4C, Dalwhinnie 10.7C maximum, Aboyne 0.3C minimum, Kinlochewe 6.4 mm, Wattisham 10.4 h.)

Low pressure to the S of Iceland pushed areas of frontal rain across W and N Scotland overnight into the 11th and across much of Scotland, Ireland and parts of N England during the day. The rain weakened as it pushed SE'wards. After a mild night across much of Scotland and Ireland, there were showers here during the day once the rain had cleared, while much of S Britain was dry - with sunny spells away from SW England. (Frittenden 20.7C, Spadeadam 13.3C maximum, Santon Downham 3.6C minimum, Achnagart 51.6 mm, Shoeburyness 8.2 h.)

After a sunny start in E and N areas on the 12th, rain spread across much of Scotland, N Ireland and eventually N England - although some eastern districts, notably Aberdeenshire, were in a rain-shadow. S Britain was mostly sunny, while temperatures were near or rather below normal in most places. (Heathrow 22.7C, Loch Glascarnoch 12.1C maximum, Drumnadrochit 5.5C minimum, Achnagart 37.4 mm, Waddington 10.9 h.)

N and Cent areas of the British Isles were blustery on the 13th due to a wave depression that pushed rapidly across Cent Scotland, ahead of rising pressure from the S. Overnight there was widespread rain across Scotland, N Ireland and N England that was especially heavy in parts of Scotland. Much of England, Wales and Ireland had a mild night with minimum temperatures remaining above 15C in a few places. Rainfall during the day was mostly confined to N and Cent Scotland with much of Cent and S England, S Wales and S Ireland having a warm and sunny day; maximum temperatures rose above 25C in parts of E England and the London area. The early windy conditions led to a closure of the railway line between Fort William and Crianlarich. Further south, the A83 at Rest and Be Thankful was closed following a "significant landslide"; around 80 mm of rain fell in 24 hours, causing 1,000 tonnes of material to slide down the hillside and close the road for the second time in six weeks. (Kew Gardens 25.9C, Lerwick 12.1C maximum, Exeter Airport 6.5C minimum, Achnagart 120.2 mm, Jersey Airport and Shoeburyness 11.8 h.)

Low pressure persisted throughout the 14th over N and W Scotland, but pressure was high elsewhere with a mainly S'ly flow. This led to a mild night across parts of S England, the Channel Islands and S Ireland and a very warm day over most of England and Wales away from the coasts. It was rather cloudy across most of Ireland and Scotland but sunny elsewhere. It was a wet day over N Scotland, with some rain later in W Ireland. (Jersey Airport 30.8C, Lerwick 14.0C maximum, South Newington 5.8C minimum, Lerwick 17.4 mm, Jersey Airport and Leconfield 11.9 h.)

The 15th brought some more very warm or hot and sunny weather, but two cold fronts did introduce rather more cloud; the hottest weather was in the extreme southeast, where the sunshine was unbroken. Rain from the original cold front in the north became much lighter and more patchy as it edged southwards over Scotland, whilst the 'inner' cold front drifting eastwards across Wales and England brought a fair amount of cloud and a few patches of light rain. There was some coastal fog in the southwest and far north - and also a few fog patches inland in the south at first. Daytime temperatures were widely above 25C, away from the SW and coastal areas. (Frittenden 31.3C maximum, Baltasound 13.2C maximum, Topcliffe 6.5C minimum, Tyndrum 17.8 mm, Manston 10.6 h.)

High pressure prevailed on the 16th, but slow-moving fronts led to rather cloudy skies across much of S and Cent Scotland, N England and N Ireland. There were some fog patches in some S parts of the UK, especially near SW coasts, where it stayed foggy all day in places. The day followed a warm night across many areas of Ireland, Wales and England with minimum temperatures remaining above 15C overnight. There was a little light rain overnight in places but the day was mainly dry (if rather cloudy in places) with temperatures reaching 25C in parts of Cent S England. (Hurn 26.8C, Lerwick 11.4C maximum, Resallach 3.5C minimum, Aviemore 1.6 mm, Lyneham 10.7 h.)

High pressure continued to dominate the weather on the 17th, although frontal cloud affected N Scotland and W Ireland although precipitation amounts were slight. S England and the Channel Islands had a mild night, while during the day many areas across the British Isles saw temperatures reaching 17-20C, except on the Northern Isles. (Porthmadog 23.1C, Fair Isle 12.7C maximum, Shap 2.8C minimum, Lerwick 0.6 mm, Bude 11.3 h.)

High pressure resulted in an E'ly flow across many S areas of the British Isles on the 18th. The day followed a cool night in some areas, with a ground frost in parts of N England. Most places were dry during the day, although there was some rain across the Northern Isles. Away from N Scotland there were long, sunny spells in most areas with temperatures reaching 20C in most areas away from the coasts. (Tyndrum 22.8C, Fair Isle 13.8C maximum, Shap 0.7C minimum, Fair Isle 1.0 mm, Tiree 11.6 h.)

High pressure on the 19th led to a mainly dry day across the British Isles with a mainly sunny day away from the extreme N and S locations. The day followed a cool night in parts of S Scotland, N England and N Ireland, although in parts of S England and the Channel Islands overnight minimum temperatures remained above 15C. It was a warm day in many places with temperatures as high as 20-23C in parts of N Scotland. A frontal system over N France led to some rain in the Channel Islands and Cornwall later in the day; Jersey Airport reported 4 mm in the 12 hours ending 1800 GMT. (Heathrow and St James's Park 25.2C, Fair Isle 13.1C maximum, Newton Rigg 1.9C minimum, Chillingham Barns 0.4 mm, Morecambe 11.5 h.)

Pressure remained generally high on the 20th. Overnight it was again warm in parts of S England and the Channel Islands with minimum temperatures above 15C in a few places. N and E Scotland and parts of NE England had a few light showers overnight with a few further falls during the day in SE Scotland and NE England. N Scotland, SE Scotland and NE England were dull in places with some fog over Shetland; most other areas saw sunny spells at times during the day, which was warm the time of year in inland areas of Cent S England. (Kew Gardens and St James's Park 25.6C, Lerwick 12.4C maximum, Magilligan 1.2C minimum, Loftus 3.2 mm, Aberdaron 11.1 h.)

The 21st was a mainly dry day, except across N and NW Scotland where a frontal system brought rain from the NW later in the day. England, Wales and Ireland started rather misty in many areas, with some fog patches there was a cool start to the day in parts of N Ireland, S Scotland and N England with a ground frost in places. Away from N and W Scotland and N Ireland most places had a sunny day and daytime temperatures reached 24-26C in parts of Cent S England. (Yeovilton 26.0C, Lerwick 12.2C maximum, Ravensworth 1.1C minimum, Harris Quidnish 8.8mm, Leconfield 11.0 h.)

A frontal wave developed on the 22nd along a cold front initially lying over N Scotland. There was rain across N Scotland overnight while mist and fog patches formed across many parts of England and Wales before dawn. Once the mist and fog cleared it was a sunny day in East Anglia, but rather cloudy elsewhere, especially over Ireland and Scotland where there was SE'ward-moving rainfall during the day. By late evening the rain had spread into parts of N England, Wales and SW England. Daytime temperatures reached 25-26C in parts of East Anglia and SE England. (Santon Downham 26.0C, Dalwhinnie 11.8C maximum, Aboyne 5.1C minimum, Achnagart 40.4 mm, Waddington 10.5 h.)

Bands of frontal rain crossed many areas in an E'wards direction on the 23rd, but became slow-moving in the evening over E areas of England as a wave depressions formed on the front over Lincolnshire. To the rear of the fronts there was an early ground frost in N and Cent Scotland although S England had a mild night with minimum temperatures above 15C in places. During the day there were some heavy falls of rain in parts of E England with showers following the rain over Scotland and Ireland. England and Wales remained rather cloudy, but there were sunny periods over Ireland and Scotland during the day. (Manston 20.6C, Shap 9.6C maximum, Aboyne 0.0C minimum, Cambridge NIAB 34.4 mm, Kinloss 10.0 h.)

Areas of low pressure persisted close to, or over, the British Isle son the 24th; at the surface there was an inflow of air from the N. The UK had its coldest September night in 23 years after -5.0C was recorded in Altnaharra in the Highlands. The same temperature was recorded previously on the night of 19-20 September 1997 at Corgarff and Boultenstone in Aberdeenshire. The record coldest September night was in 1942 at Dalwhinnie with -6.7C. Rain fell overnight across many areas of England, Wales and Ireland. The day was rather cloudy everywhere, although N and Cent Scotland remained dry for much of the day with the best of the sunshine. Elsewhere, there were spells of rain and showers. Thunderstorms and thundery showers moved NE'wards across areas of Ireland, Wales and England from mid-morning onwards, with some heavy outbreaks over Yorkshire in the late afternoon and evening. A supercell storm of heavy showers, hail and thunder left parts of West Yorkshire under a thick blanket of hailstones in the evening. The storms, which began at about 1500 GMT, battered much of the region with lightning continuing for several hours. Hail was reportedly up to 2.5 cm in diameter in places. People living in Baildon, Guiseley, Otley and Menston, shared images on social media of the flash storms leaving them in several centimetres of hail. About an hour after the hailstorm, a small tornado was spotted swirling towards Ilkley Moor. The tornado was relatively small and did not cause any damage. (Manston 18.2C, Bainbridge 8.5C maximum, Altnaharra -5.0C minimum, Killowen 24.6 mm, Tiree 8.8 h.)

By midday on the 25th there as a deep area of low pressure (centre 985 mb) over the S North Sea, drawing a cool N'ly flow across the British Isles. There was a slight ground frost in some sheltered inland areas from N Scotland to SE Ireland and Cent S England, while some heavy rain fell before dawn across parts of E England and East Anglia. The day was blustery with the rain in the E being slow to clear and with showers in many other areas. In between the showers there were sunny periods in all areas, although it remained dull in East Anglia. Parts of N Norfolk reportedly had their wettest September day for more than 30 years, while Weybourne in Norfolk recorded a wind gust of 67 mph. There was flooding in parts of Norfolk and Suffolk. Gales also caused damage across Norfolk; hundreds of trees and branches were blown down blocking roads according to Norfolk police. Thousands of homes were without electricity. Trains were suspended between Ipswich and Felixstowe in Suffolk because of a fallen tree. The Tropical House at Amazona Zoo in Cromer was damaged by the storm. Weybourne had 44 mm of rain in the 24 hours from 0900 GMT 9am which made it the wettest September day there since records began in 1989. (Hurn 16.4C, Braemar 9.0C maximum, Tyndrum -1.5C minimum, Houghton Hall 66.6 mm, Ronaldsway 10.1 h.)

Pressure remained low over the North Sea on the 26th and many places continued to have a brisk N'ly flow as pressure built towards the NW of the British Isles. Overnight rain continued over parts of E England, while there were further outbreaks for a time in SW England, SW Ireland along with some showers in other areas. The recent winds led to a clean-up operation after a seaside village became covered in sand blown off a beach in high winds. Cars, gardens and roads in Walcott, Norfolk, were left concealed by the storm on Friday and Saturday. The rain in E England gradually turned showery with most other areas remaining dry with long, sunny spells, before turning cool in the evening across N Ireland and N Scotland. (Prestwick 15.2C, Fylingdales 9.5C maximum, Katesbridge -1.5C minimum, Tibenham Airfield 11.2 mm, Dundrennan and Glasgow 11.0 h.)

There was a widespread air frost across many inland areas of Scotland and N Ireland into the 27th with a ground frost as far S as S Ireland and S Wales. Cloud and some light rain affected E areas of England overnight. Overnight saw the coldest September night on record for Northern Ireland, as Katesbridge reported a minimum temperature of -3.7C. It was also the coldest September night on record across the whole island according to Met Eireann; the Republic of Ireland's previous coldest September night on record was in 1972 when -3.5C was recorded at Clonsast in County Offaly. At Braemar the minimum of -5.0C equalled to recently recorded minimum at Altnaharra on the 24th. It remained cloudy with some light rain in E England during the day, but elsewhere in E Ireland, Wales and England it was a sunny day. Cloud and rain spread into W Ireland later in the day. (Cardiff Bute Park 18.8C, Loch Glascarnoch 9.5C maximum, Braemar -5.0C minimum, Brooms Barn 5.0 mm, Exeter Airport 11.2 h.)

Fronts spread rain and showers across Ireland and W Scotland overnight into the 28th; clearer skies led to an overnight air frost in parts of E Scotland, NE England and the Midlands. During the day the cloud and rain spread E'wards, reaching the Midlands around midday and East Anglia in the early evening although the bulk of the rain was confined to Wales, W and N England, Ireland and Scotland by late afternoon. It turned sunnier as the rain cleared from W Scotland and Ireland turning cool in these areas in the evening. (Ravensworth 19.0C, Eskdalemuir 11.8C maximum, Ravensworth -1.3C minimum, Chivenor 6.8 mm, Shannon Airport 7.9 h.)

An area of mainly light rain cleared E'wards from E areas of England during the morning of the 29th. Clearing skies then led to a cold night in some parts of Scotland, N England and N Ireland. Skies then partially cleared in most places (except in and around East Anglia) for a while, helping to give a mild day in parts of S England. There were a few showers in places ahead of another area of more general rain that affected much of Ireland by mid-evening. (Manston 21.2C, Dalwhinnie 11.9C maximum, Katesbridge -1.4C minimum, Bedford 9.8 mm, Leeming 10.1 h.)

There was some early mist in places from Yorkshire to Hampshire before dawn on the 30th - by which time had spread across Ireland and into many parts of Wales and Scotland. In the 12 hours ending 0600 GMT Valentia reported a fall of 27 mm, although in this period there was a slight ground frost in parts of E Scotland. During the day the rain spread E'wards with some showers following in the W behind the rain. It was a cloudy day in all areas with temperatures falling as the rain cleared. (Manston 19.1C, Dalwhinnie 10.6C maximum, Redesdale Camp 1.6C minimum, Whitechurch 33.4 mm, Wattisham 2.9 h.)

British Isles weather, October 2020

Low pressure centres close to the British Isles during the 1st led to an unsettled day in many areas. Overnight falls of rain were widespread, although these were mainly light over Ireland and W Scotland. There was some air first across Northern Ireland, with a ground frost in areas of E Ireland. Rain fell for much of the day across N and NE Scotland, and another area of rain spread across Ireland and into S Wales, SW and Cent S England by mid-evening. It was cloudy day across N and Cent Scotland, with varying amounts of sunshine elsewhere. (Frittenden 16.8C, Dalwhinnie 7.9C maximum, Katesbridge -1.4C minimum, Lerwick 33.0 mm, Dundrennan 10.7 h.)

The centre of storm Alex remained close to Brittany during the 2nd, giving gales across coastal areas of S England and rain across S Wales and S England that moved N'wards to affect parts of N England in the evening. Overnight rain across N Scotland cleared away in the morning; during the day the sunniest spots were across Scotland (except the Shetland) and E Ireland with most of England remaining dull. Gale-force winds reached 71 mph at Berry Head (Devon) during the day. Following an overnight air frost in parts of N Ireland, S Scotland and N England, it was a cool day over England, Wales and Ireland with temperatures failing to reach 13C in many places. (Auchincruive 16.2C, Pennerley 9.6C maximum, Shap -2.4C minimum, Liscombe 65.0 mm, Kinloss 10.5 h.)

As Alex moved away SE'wards on the 3rd, another low centre formed over E England (982 mb over Lincolnshire at 1800 GMT). Overnight there was rain across N and E Scotland, and widespread rain across England and Wales during the day rain was widespread over the UK with lesser falls over Ireland. Away from W Ireland it was a dull day as a result, and much of the UK was also cold. Following widespread, heavy rain, police warned motorists to take care, while in Essex, firefighters rescued a family of four when their car became trapped in floodwater. By early evening, 84 mm of rain had been recorded in 36 hours in Liscombe and 74.4 mm recorded in Brendon Hill in Devon. At Oxford Radcliffe Observatory 60 mm of rain fell in the 24 hours beginning 0900 GMT, an October record there (records go back to 1827); the previous day's rainfall (2nd) was 37.6 mm, so the two-day rain total was just 0.5 mm below the all-time record from 9-10 July 1968. However, the total rainfall during 1-3 October was 104.8 mm, the wettest three-day spell in the record. Bournemouth has just had its first hat-trick of days with over one inch (25.4 mm) of rain since records began in 1879. The individual totals were 34.8 mm on the 1st, 27.5 mm on the 2nd and 25.6 mm on the 3rd. According to the Met Office, today was the wettest day across the UK as a whole since records began in 1891; an average of 31.7 mm of rain across the entire UK. The previous record wettest day was 29 August 1986. (Wiggonholt 16.6C, Dalwhinnie 6.7C maximum, Machrihanish 0.9C minimum, Craibstone 66.0 mm, Shannon Airport 8.7 h.)

Low pressure was slow-moving across England on the 4th - centred over the Midlands with a pressure of 980 mb at 1200 GMT. Rain was widespread overnight, but became increasingly restricted during the day to a semi-circle around the depression over Cent England - mainly affecting N Scotland, N and E Ireland, S England and East Anglia, and eventually easing from many of these areas. Elsewhere there were a few showers with some sunshine over S Scotland and N England. It was cold and blustery in many of the wetter areas. More than a dozen gardens in a street have been filled with raw sewage after drains overflowed during heavy rainfall in Oxford; residents of Campbell Road, Oxford, had floods 60 cm deep in their gardens. Parts of Somerset and Hampshire saw a month's worth of rainfall in 42 hours, while homes were flooded in Hemel Hempstead. The River Coquet burst its banks at Rothbury in Northumberland. Safety checks were carried out on rail lines and bridges following heavy rain overnight in parts of Scotland. Train passengers were warned to expect disruption after Network Rail inspectors discovered flooding on lines in Fife, Aberdeenshire and Angus. Homes in Abergwyngregyn in Gwynedd have been flooded for the second time in six weeks after a river burst its banks. (Auchincruive 18.0C, Okehampton 9.4C maximum, Okehampton 6.1C minimum, Swyddffynnon 48.2 mm. Dundrennan and Morecambe 6.0 h.)

The low pressure centre remained close to the E coast of the UK on the 5th. Areas of rain and showers affected most areas of the British Isles overnight and during the day but there were sunny spells over N Scotland and SE England in particular. Temperatures were locally warm in the brighter areas in the south, whilst some of the wetter areas were cool. (Heathrow 18.5C maximum, Okehampton 11.0C maximum, Loch Glascarnoch 4.6C minimum, Altnahinch Filters 21.0 mm, Lerwick 8.6 h.)

On the 6th the low pressure centre remained close to N Scotland. Overnight it was mild for the time of year over the Northern Isles, and also S of a line Belmullet-Isle of Wight. There were spells of rain and showers over most areas and away from S districts it was cool in places. Some of the showers were heavy, and there was thunder in the afternoon over parts of the N and E Midlands and East Anglia. Many areas also had sunny intervals. (Heathrow 17.4C, Sennybridge 11.1C maximum, Katesbridge 3.5C minimum, Rochdale 43.2 mm, Cork Airport 6.8h.)

Low pressure to the N led to a mainly W'ly flow during the 7th, although during the evening a shallow depression moved E'wards across Cent Ireland. There was some rain overnight across areas of Scotland and N England. During the day there were sunny spells, with a few showers in the N. Rain spread from W Ireland across Wales and much of England into the evening. Temperatures were near or rather below normal. 11 mm of rain fell at Valentia in the 12 hours ending 1800 GMT. (Teddington Bushy Park 17.4C, Dalwhinnie 9.9C maximum, Aboyne 3.6C minimum, Resallach 35.8 mm, Wattisham 7.9 h.)

On the 8th outbreaks of rain and blustery winds around a cold front cleared slowly to the southeast, leaving SE Kent in mid-afternoon but lingering over the Channel Islands. It was rather warm just ahead of the cold front (with overnight minimum temperatures around 14C in Cornwall), otherwise most places had quite a chilly day with some sunshine, and showers in the north. A longer spell of rain moved into western Scotland in the evening. (Writtle 19.1C, Tulloch Bridge 9.2C maximum, Kinbrace -0.1C minimum, Capel Curig 37.4 mm, Dundrennan 8.5 h.)

An area of low pressure oved E'wards just N of Scotland on the 9th pushing a cold front SE'wards across all areas during the day. The day was mostly fairly cloudy, chilly and showery, with some sunshine. Towards the SE England coast, it was sunny until mid-afternoon, with seasonable temperatures. (Swanage 15.9C, Loch Glascarnoch 7.2C maximum, Kielder Castle 1.1C minimum, Achnagart 21.2 mm, Jersey Airport 7.3 h.)

Overnight rain into the 10th across W Scotland, and later N England, gradually spread to other areas during the day but it turned showery. There was an early ground frost in parts of Cent Scotland, E Wales and the Midlands. It was especially showery during the day across N and E areas of the UK, where there were some longer spells of rain. There was isolated thunder in E England, but also some sunshine - especially in the S Ireland, SW England and the Channel Islands. (Armagh 15.5C, Balmoral 9.2C maximum, Dalwhinnie -0.1C minimum, Resallach 22.8 mm, Dublin Airport 8.2h.)

A weak ridge of high pressure brought a drier day on the 11th. Most places were dry with sunny spells, although it was cloudier near E (and at first some W) coasts of the UK with some showers. Cloudier weather spread from the NW across most areas during the afternoon and evening, with rain following into W areas of Scotland and Ireland. (Cardiff Bute Park 16.3C, Loch Glascarnoch 9.0C maximum, Shap 0.9C minimum, Capel Curig 9.4 mm, Rostherne 7.9 h.)

Overnight into the 12th frontal rain spread across Ireland and into Cornwall and W and N areas of Scotland. It was a mild night in W Ireland where overnight minimum temperatures remained above 10C. Much of England and Wales had a cloudy day as the rain and drizzle spread from the W on a cool day. It became drier and brighter in W areas of the British Isles as the day progressed. (Plymouth 15.7C, Lerwick 8.4C maximum, Exeter Airport 2.9C minimum, Kinlochewe 21.6 mm, Cork Airport 6.2 h.)

A shallow area of low pressure moved S'wards over the North Sea close to the E coast of England during the 13th. A N'ly flow led to a cool day; there was a slight air frost before dawn over parts of S Scotland and adjacent areas of N England. Areas of rain and showers affected many area of the British Isles. There was some sunshine, but it remained rather cloudy in many parts of E England. (Usk No.2 14.6C, Dalwhinnie 8.4C maximum, Eskdalemuir -0.8C minimum, Capel Curig 21.8 mm, Tiree 9.0 h.)

As pressure rose over N Scotland on the 14th an E'ly flow became established across the British Isles. It was a rather cloudy day in many places; elsewhere there were sunny spells, but there were also showers - especially over SE Scotland, E and Cent England. Many places were quite cool, but it was locally on the warm side in the brighter parts of the S and W. (Armagh 17.2C, Lerwick 9.0C maximum, Kinlochewe 1.4C minimum, Chillingham Barns 15.0 mm, Ronaldsway 9.6 h.)

High pressure prevailed across the British Isles on the 15th - MSL pressure generally above 1032 mb over the Northern Isles and this helped to produce an early air frost in parts of Cent Scotland with a ground frost in a few places as far S as SW Ireland, the Midlands and Norfolk. Much of Scotland and NE England was cloudy; elsewhere there were sunny spells. A few showers affected Cent and E England. It was mostly rather cold away from W and S Ireland and some S areas of England. (Valentia 15.7C, Dalwhinnie 6.9C maximum, Tyndrum -3.3C minimum, Manston 7.4 mm, Aberporth 9.8 h.)

Away from NE Scotland and parts of E England, in most areas the 16th was a mainly dry day. There was a slight air frost in a few sheltered parts of NW England, but for most places the day was rather cloudy with some patchy drizzle or rain. The best of the sunshine was to be found in parts of Cornwall, W Wales and W Scotland. It was a cool day in all areas. (Gosport Fleetlands 15.4C maximum, Pennerley 8.4C maximum, Shap -1.6C minimum, Wittering 3.8 mm, Camborne 8.6 h.)

There was a slight ground frost in some places into the 17th where cloud cleared for a time overnight, but in general the skies remained rather cloudy all day. A few parts of SW England and N wales saw some sunny spells, elsewhere there were a few patches of mostly light rain or drizzle although one or two heavier bursts of rain affected some E coastal districts. A depression pushed some rain into SW Ireland in the late afternoon and mist formed in parts of Cent England in the evening. (Bridlington 14.7C, Lerwick 7.8C maximum, Loch Glascarnoch -1.3C minimum, Kinloss 5.4 mm, Aberdaron 8.0 h.)

Low pressure SW of Ireland and S'ward-moving fronts over the UK on the 18th led to another cool and cloudy day. Little rain fell from any of these systems, but the day was generally rather cloudy and cold with an early air frost in parts of Cent Scotland. (Killowen 15.3C, Loch Glascarnoch 7.0C maximum, Resallach -1.6C minimum, Loftus 4.4 mm, Bude 5.3 h.)

Low pressure to the W on the 19th drew a S'ly flow across most areas. Overnight, spells of rain were widespread across Scotland and Ireland. This became heavier in W Scotland and W Ireland during the day and the rain spread into W and N areas of England and Wales. Parts of E and S England had some sunny periods; it was mostly rather cool and became increasingly windy. (Kew Gardens 16.3C, Lerwick 7.2C maximum, Shobdon 2.0C minimum, Tiree 72.8 mm, East Malling 5.2 h.)

Low pressure moved slowly N'wards over W Ireland on the 20th; central pressure 982 mb near Belmullet at 1800 GMT. After overnight rain, there were sunny spells over England and Wales, but also some showers (away from the southeast). Further rain spread across much of Ireland and Scotland. Except in the wetter areas, many places became rather warm, but it was breezy. (Kew Gardens 19.0C, Lerwick 7.9C maximum, Lerwick 6.3C minimum, Harris Quidnish 51.2 mm, Guernsey Airport 6.7h.)

Areas of low pressure and associated frontal systems over the British Isles on the 21st led to a generally unsettled day. There were a few hours of rain over SE areas of England. It was rather more showery elsewhere, and parts of E Scotland were quite sunny. The far NW of Scotland had some more persistent rain. It was chilly over N Scotland and Ireland, but milder in most other areas. (Edinburgh Botanic Gardens 17.3C, Lerwick 7.8C maximum, Lerwick 7.2C minimum, Altnaharra 27.0mm, Dyce 5.1 h.)

The was a slight ground in places into the 22nd in S Ireland, although it was milder elsewhere overnight but wet in parts of Cent and E Scotland. During the day it was fairly cloudy and showery day over much of the British Isles, especially over S Scotland and N England. It was quite sunny in places in E and S England and in S Ireland. It was mostly rather cold, but locally on the warm side in SE England and parts of East Anglia. Emergency services were called out to rescue people stranded by overnight flooding in the north east of Scotland. Residents were evacuated from flooded properties in Ellon, and cars were stranded in water in Angus following heavy rain in the area. The heavy rain forced the closure of the train line between Inverness and Aberdeen on Thursday afternoon. The Scottish Fire and Rescue Service said it was called to reports of flooding in Ellon, Aberdeenshire, from about 0350 GMT. Residents were rescued from six properties. (Teddington Bushy Park 18.3C, Lerwick 7.7C maximum, Scolton Country Park 4.2C minimum, Craibstone 35.8 mm, Guernsey Airport 8.9 h.)

There was a sunny start to the 23rd in SE England with some mist and fog patches, but a rather cloudy day with showery rain affected most areas eventually during the day as early frontal rain spread E'wards from Ireland. Once the front had cleared it turned generally drier, and rather brighter, from the W during the day. After an early ground frost in parts of the Midlands and NE England, and across the Northern Isles, temperatures were mostly rather below normal in the N and W, and rather above in the SE. Strong winds over the Irish Sea led to the cancellation of ferry services between the Isle of Man and Lancashire. (Shoeburyness 17.0C, Dalwhinnie 8.1C maximum, Baltasound -0.7C minimum, Bridgefoot 16.8 mm, Shannon Airport 6.7 h.)

A deep low to the W of N Scotland on the 24th led to a windy day in many areas at times, with spells of rain and showers as associated fronts crossed the British Isles. It was wet overnight in Ireland and W Scotland; rain then spread slowly across all areas, with rather brighter, showery weather (with isolated thunder) following in N and W Scotland. Many parts of England and Wales were wet for much of the day, although much of East Anglia and Kent only had a little rain until the evening. It was rather cool in the N and W, but quite mild in SE areas. England, Wales and S Scotland remained dull all day. (Jersey Airport 16.9C, Lentran 8.4C maximum, Fyvie Castle 0.6C minimum, Capel Curig 34.0 mm, Magilligan 6.8 h.)

Low pressure remained centred close to W Scotland on the 25th, which was generally showery, with thunder in a few places. There was some sunshine, and there were very few showers generally in the east. It was mostly rather cool, and blustery in the N and W. (St Helier 14.7C, Dalwhinnie 6.7C maximum, Drumnadrochit -0.1C minimum, Tredegar Bryn Bach 32.2 mm, Dublin Airport 8.0 h.)

An area of low pressure moved across Scotland from the W on the 26th (centre 976 mb at 0000 GMT near Stornoway). It was cool overnight across England with a touch of ground in a few areas around the Midlands. Ireland and W areas of the UK had overnight precipitation while during the day sunny spells and showers were widespread, especially over N England. There was thunder along the north Norfolk coast in the afternoon. (Herstmonceux 15.0C, Spadeadam 8.5C maximum, Shobdon 0.1C minimum, Achnagart 34.0 mm, Manston 7.1 h.)

The remains of hurricane Epsilon produced a deep area of low pressure to the S of Iceland that pushed frontal bands across the British Isles on the 27th. Overnight, rain fell across Ireland, W Wales and SW England. It was dry for some time over NE Scotland, but rain and drizzle spread NE across the UK across the country - followed by brighter/clearer weather in the S and W during the afternoon and evening; there were still showers, and isolated thunder, in SW England. It was chilly and blustery in the rain, but became relatively mild in the S later. (Yeovilton 15.9C, Dalwhinnie 7.4C maximum, Aboyne 0.3C, Capel Curig 16.4 mm, Cork Airport 6.7 h.)

On the 28th there was some sunshine, but generally it was fairly cloudy (especially across S England and Cent Scotland) and showery. Some of the showers were heavy, and there was hail and thunder in parts of S Wales and S England; hailstones around 25 mm in diameter fell in the Cirencester area. The Irish Marine Data Buoy Observation Network recorded 'Phenomenal' seas off the west coast today; a Phenomenal sea is classified as having a significant wave height of 14.0 m or more and this was recorded at both M6 and M3 buoys. The depression responsible for these waves was ex-hurricane Epsilon. The M3, M4 and M6 have recorded significant wave heights continually greater than 9 m, which are categorized as 'Very High' seas since Tuesday evening. Individual waves of 20.04 m, 16.9 m and 21.7 m have also been recorded at these buoys, respectively. A house in Carmarthenshire was severely damaged after being hit by lightning; the property in Rhosnewydd, Tumble, was hit shortly before 0700 GMT. A spokeswoman for Mid and West Wales Fire and Rescue Service said the lightning strike had caused "severe damage throughout the property". She added another property had suffered minor damage. (Frittenden 14.4C, Dalwhinnie 6.9C maximum, Lossiemouth 0.8C minimum, Achnagart 49.4 mm, Weybourne 5.5 h.)

Rain and drizzle moved NE'wards across the British Isles on the 29th, after a bright start in NE-most districts. It became drier in the S later, and quite mild behind the warm front; the northeast was chilly after an early ground frost in parts of NE Scotland. It was blustery in the west with some very heavy falls f rain in parts of NW England and N Wales. Strong winds and low pressure linked to ex-hurricane Epsilon in the North Atlantic created huge waves off the coast of Cornwall, attracting daredevil surfers and body boarders. The RNLI warned of a "colossal swell" and "extremely dangerous conditions", advising people to stay out of the water. (Jersey Airport 15.8C, Braemar 7.9C maximum, Fyvie Castle -0.8C minimum, Capel Curig 74.0 mm, Lerwick 5.1 h.)

The 30th was a mild day in Cent and E England, with near-normal temperatures elsewhere. NW England and N Wales were wet overnight with further rain in Wales during the day. Elsewhere, S Britain was cloudy with patchy rain or drizzle, especially in the SW. After overnight rain, Cent and N districts brightened up, but it was showery in NW Scotland. Scotland and Ireland had a sunny day, elsewhere it was rather cloudy. (Hereford 17.6C, Dalwhinnie 8.4C maximum, Castlederg 5.5C minimum, Capel Curig 23.0 mm, Leuchars 6.7 h.)

A deep area of low pressure moved from W of Ireland towards NW Scotland on the 31st; this was storm Aiden, centre 968 mb to the W of Stornoway at 1200 GMT. Rain spread across the British Isles, followed by brighter weather in S Britain, but only short drier intervals in Scotland. It was windy in the W and N, with gales in the more exposed regions; there were gusts of up to 80 mph in the Scottish islands. Temperatures were mostly above normal in a S'ly flow. Many ferry sailing around Scotland were cancelled due to the wind and sea conditions. (Kinloss 16.5C, Lerwick 11.2C maximum, Redesdale Camp -0.9C minimum, Achnagart 60.8 mm, Casement Aerodrome 4.4 h.)

British Isles weather, November 2020

An area of low pressure to the W of Scotland on the 1st led to a cloudy and windy day. A warm sector to the S of a frontal wave led to a mild day across the S half of Britain. Outbreaks of rain and drizzle were widespread and there as little sunshine away from NE Scotland. The evening was exceptionally mild, and windy, over much of England and Wales. Cromer recorded 18.3C, the highest November temperature there since 1946, while Weybourne also had its highest ever November temperature with 18.1C (records started there 1986). (Hawarden 18.4C, Dalwhinnie 7.7C maximum, Kinbrace 3.4C minimum, Capel Curig 56.2 mm, Leeming 3.5 h.)

Many places SE of a line The Wash-Exeter had 1800-0600 GMT minimum temperatures of 15-16C, but by 0900 GMT on the 2nd an occluded front was pushing colder air across parts of London. Ahead of the rain in the SE this was a record mild night for November. There was heavy rain overnight across N Wales and N England with further falls here during the day. Most other areas of England, S Wales and S Ireland had sunny spells during the day while much of Scotland remained rather cloudy. Heavy rain led to rivers in Yorkshire bursting their banks, leaving roads closed and motorists stranded. Nine people were rescued by fire crews using boats on the River Ure in Appersett, North Yorkshire, when they became stuck in floodwater. (Charsfield 18.0C, Spadeadam 7.2C maximum, Drumnadrochit 4.1 mm, Capel Curig 57.0 mm, Yeovilton 6.0 h.)

Pressure rose from the SW during the 3rd, reaching 1026 mb in SW Ireland by 1800 GMT. The day dawned after a cool night with a shallow low bringing rain across much of S Wales and S England by dawn with other systems gave rain overnight across N Ireland, S Scotland and N England in particular. There were further spells of rain or showers in most places during the day although many areas also had sunny spells at times. It was a cool day in many areas, especially in N Ireland and N England. (Jersey Airport 12.4C, Spadeadam 5.4C maximum, Aboyne -1.4C minimum, Dunstaffnage 21.2 mm, Cork Airport 6.8 h.)

High pressure built on the 4th from the SW (MSL pressure 1040.3 mb at Valentia at 1800 GMT), giving much of the British Isles a dry day. There was a little rain overnight in parts of Wales, N Scotland and NW England in particular, while falls later in the day were largely confined to N Scotland. There was an overnight air frost in parts of Cent Ireland, Wales, Cent and S England with mist and fog lingering by dawn over parts of Ireland, Wales and England. Away from N and Cent Scotland most places had sunny spells at times. (Scolton Country Park 13.4C, Dalwhinnie 7.6C maximum, Benson -3.6C minimum, Achnagart 8.4 mm, Shoeburyness 8.7 h.)

High pressure continued to dominate conditions across S areas of the 5th, although the centred migrated into Europe. A few areas in S England and S Wales had an air frost while by 0900 GMT mist and fog was still widespread across Cent, S and E England with a few fog patches elsewhere. There was rain overnight across N Scotland by the day was generally dry across the British Isles. Much of Ireland, NW England and SW Scotland had a cloudy day but there were sunny spells elsewhere.

Mist or fog was widespread over Ireland, Wales, England and E Scotland by dawn; the fog was slow to clear in places and many areas remained misty all day. Frontal rain spread into S Ireland by midday, later affecting much of Ireland and SW England; mist returned widely over the UK in the evening. The best of the sunshine during the day was to be found across East Anglia while it was a warm day in many parts of S England and Wales. (Trawsgoed 17.4C, Strathallan 3.6C maximum, Tulloch Bridge -3.3C minimum, Culdrose 7.8 mm, Weybourne 7.4 h.)

Low pressure to the SW of the British Isles on the 8th pushed frontal rain across all areas during the day. Ahead of the rain there was some mist and fog across Scotland and England, and air frost in Cent Scotland, and also some sunshine in East Anglia and Kent. Away from these areas, and also parts of E Ireland, it was a dull day although temperatures rose above 15C in parts of Ireland, S England and East Anglia. (Trawsgoed 17.1C, Lentran 7.2C maximum, Aviemore -2.9C minimum, Derrylin Cornahoule 15.8 mm, Casement Aerodrome 6.1 h.)

There were some mostly coastal showers in the S and W. (Wisley 16.8C, Cassley 9.3C maximum, Altnaharra -0.3C minimum, South Farnborough 7.2 mm, Kinloss 5.5 h.)

A S'ly flow ahead of a low pressure system to the NW of Ireland at 1200 GMT on the 11th led to a mainly mild day. Overnight rain affected Ireland and parts of W and Cent Scotland with Valentia reporting 24 mm in the 12 hours ending 0600 GMT. Overnight minimum temperatures at Scilly and in SW Ireland remained above 12C. The rain spread across Scotland and parts of N England in the morning, and across Wales in the afternoon, with falls elsewhere over England later.

There was also overnight rain in Scotland, Wales and Ireland with further widespread falls during the day as fronts spread E'wards across many areas. Some of these falls ere heavy over parts of S England. It was a mild day in all areas. (Gogerddan 16.0C, Cassley 8.5C maximum, Cassley 4.1C minimum, Otterbourne Water Works 31.4 mm, Casement Aerodrome 2.4 h.)

An area of low pressure moved across Scotland from the W during the 15th (centre 979 mb near Arran at 1200 GMT) with associated fronts and a W'ly airflow giving spells of rain and showers to most areas during the day. The best of any sunshine was across England and Wales. Showers across S Wales and S England were thundery in places during the afternoon. (Sutton Bonington 13.1C, Okehampton 7.3C maximum, Drumnadrochit 3.3C minimum, Wych Cross 34.6 mm, Hawarden 5.4 h.)

Rain and showers were widespread into the 16th across Scotland, N Ireland, N England and N Wales. The day was rather cloudy with further frontal rain across Ireland and Wales later spreading across England. The best of any sunshine was across E Scotland although by late evening rain had also spread across many areas of Scotland from the W. (Hereford 14.2C, Dalwhinnie 7.1C maximum, Altnahinch Filters 4.0C minimum, Capel Curig 28.2 mm, Kinloss 3.3 h.)

A SW'ly flow under a warm sector meant a mild day for most of the British Isles on the 17th. Overnight minimum temperatures were widely above 10C across Ireland, Wales, W and S England. It was a wet day across much of W and N Scotland and a generally cloudy one in all areas with other areas of rain particularly across Wales, Ireland and some W areas of England. Maximum temperatures rose to 15C in places as far N as E Scotland. (Hawarden 16.3C, Baltasound 9.0C maximum, Loch Glascarnoch 6.1C minimum, Tyndrum 81.0 mm, Shoeburyness 2.6 h.)

A cold front crossed all areas from the W during the 18th, with a N'ly flow becoming established across N Scotland by the evening, around a low centre located to the E of Shetland. Overnight it was mild (minimum temperatures above 10C in most areas away from Cent and N Scotland) with rainfall across Ireland and Scotland. There was further widespread rain across Ireland and Scotland during the day with lesser falls from a cold front for a while across Wales and England. It was a mild and rather cloudy day ahead of the front, but sunnier to the rear across Ireland with some showery falls.

Many Cent and E areas of England and Scotland had a slight air frost into the 20th, ahead of areas of rain that spread across Ireland and into W Britain before dawn. The rain then spread E'wards during the day, ahead milder conditions. There was some sunshine in East Anglia and Kent ahead of the rain elsewhere it was a dull day. (Cassley 14.0C, Okehampton 8.3C maximum, Aboyne -5.3C minimum, Capel Curig 20.0 mm, Manston 4.0 h.)

It was a mild night into the 21st in most areas being generally cloudy and with rain across many areas of Ireland and Scotland. This rain, along a cold front, made slow progress SE'wards during the day with much of S England and East Anglia remaining dry by mid-evening. It was a cloudy day ahead of the rain, but it brightened up as the rain passed and temperatures fell. There were widespread showers across Scotland following the frontal passage. (Hawarden 13.8C, Loch Glascarnoch 6.4C maximum, Balmoral 2.9C minimum, Achnagart 25.6 mm, Dyce 5.7 h.)

The cold front became slow-moving over, or close to, S England on the 22nd. Overnight temperatures close to the English Channel remained generally above 10C. Rainfall amounts from the front were slight, while there were areas of showers at times across N Ireland, W and N Scotland at times overnight and during the day.

(Gosport Fleetlands 12.5C, Dalwhinnie 4.4C maximum, Katesbridge 0.1C minimum, Achnagart 14.2 mm, Dublin Airport 6.6 h.)

A weak ridge of high pressure brought mostly dry conditions, away from parts of N Scotland, overnight into the 23rd - with a slight air frost in parts of England and Wales. E and Cent England had sunny intervals in places, but cloud spread from the W bringing rain across much of Ireland and Scotland by evening with falls later across parts of N England and Wales. It became warm across much of Ireland by mid-evening with Valentia reporting 12C at 2100 GMT. (Killowen 13.3C, Fylingdales 6.8C maximum, Santon Downham -3.4C minimum, Achnagart 44.6 mm, Weybourne 6.3 h.)

Rain affected most areas of Scotland and Ireland into the 24th and also during the day, with lesser falls across parts of Wales and N England.

A cold front made slow progress E'wards across England and Wales on the 25th, bringing a light fall of rain and a fall in temperature. To the rear of the front there was a slight air frost in parts of Scotland, and a ground frost in places here and also in Ireland. Ahead of the front it was a cloudy day but sunny periods were widespread once any rain had cleared. There was some mist and fog at first across parts of Ireland, with mist in parts of England in the evening under clearing skies. (Wisley 14.9C, Spadeadam 6.1C maximum, Aboyne -1.2C minimum, Okehampton 13.2 mm, Cork Airport 7.6 h.)

The 26th dawned with mist and fog across much of Ireland, Wales and England, this being slow to clear across parts of E Wales and the Midlands. It was fairly cloudy in many areas, and there were a few showers or patches of light rain, mainly near coasts. There were brighter areas, especially in the SW and parts of the Midlands. The fog returned rather more widely during the evening. Away from the fog, daytime temperatures were mostly not far from normal, with local air frost early and late. (Jersey 12.7C, Llysdinam 1.4C maximum, South Newington -3.1C minimum, Aultbea 5.6 mm, Bude 7.3 h.)

Fog was again widespread overnight into the 27th across Ireland, Wales and England; thick fog over parts of Cent and E England was slow to clear, and a few patches persisted all day. Otherwise it was mostly cloudy, although there were a few sunnier areas over England and Wales, and in SE Ireland. There was rain during the morning in the more SE'ly regions, with a little rain or drizzle at times during the day towards S coasts in the UK, light showers near some coasts elsewhere and more persistent light rain over parts of Northern Ireland and W Scotland. A few heavier outbreaks of rain edged into the southwest in the evening, with thunder near Scilly. Away from the foggy areas (where, as in E Scotland, there was also some overnight frost), temperatures were not far from normal. (Guernsey Airport 11.8C, Libanus 1.6C maximum, Aboyne -4.6C minimum, Aultbea 8.8 mm, Leconfield 6.6 h.)

On the 28th Most of Scotland and Northern Ireland was dry with sunny spells, although there were one or two persistent fog patches. Outbreaks of rain moved N'wards across much of England and Wales overnight and during the morning; there was very little rain in the SE and it slowly petered out late in the day over N England (having not reached Cumbria). It stayed mostly cloudy, and there were a few very misty and murky areas, but there was sunshine in the extreme SE. After overnight frost, away from the more S'ly and NW'ly regions, maximum temperatures were very variable - with some S and SW areas becoming very mild, whilst the wetter and foggy areas were rather cold. (Jersey Airport 15.5C, Strathallan 3.0C maximum, Ravensworth -5.0C minimum, St Athan 13.6 mm, Jersey Airport 7.3 h.)

The 29th was mostly dull and rather cold, although SW areas of the UK were quite mild. There were a few patches of rain or drizzle, mainly in the N and E, and sunnier interludes in the most NE'ly and SW'ly regions. Many E and Cent areas of Scotland had overnight air frost, and there were fog patches - which persisted all day in parts of Cent England and Wales. (Tredegar Bryn Bach Park 14.6C, Fyvie Castle 2.5C maximum, Aboyne -6.1C minimum, Boulmer 2.8 mm, Guernsey Airport 7.8 h.)

The 30th brought a foggy start in many Cent and S areas of England districts, whilst rain spread SE'wards across other areas. The fog cleared as the patchy rain arrived during the morning and early afternoon whilst brighter weather with some showers followed across N and Cent districts. Temperatures were mostly above normal for a time, but it turned colder from the N later. (Guernsey Airport 12.2C, Lerwick 6.3C maximum, Aboyne -1.4C minimum, Resallach 29.6 mm, Leuchars and Stornoway 2.5 h.)

British Isles weather, December 2020

Areas SE of a line Durham-Bournemouth had a sunny day on the 1st but rather large areas of cloud drifted SE'wards across other districts giving a cloudy day to much of Ireland and W Britain. There were showers near some N-facing coasts. After overnight air frost in a few places, daytime temperatures were mostly not far from normal. (Sherkin Island 12.3C, Spadeadam 3.5C maximum, Shap -4.2C minimum, Bridlington 1.8 mm, Wellesbourne 6.4 h.)

A narrow warm sector crossed all areas on the 2nd, leading to rain spreading from the NW. A few areas ahead of the warm front had an air frost overnight in E and Cent England. Brighter weather followed, although it turned very showery, with some hail, snow and isolated thunder, in the NW parts of Britain. (Isles of Scilly 11.8C, Dalwhinnie 3.8C maximum, Benson -2.7C minimum, Achnagart 20.2 mm, Dundrennan 5.1 h.)

Low pressure developed over the British Isles on the 3rd - following a fall of 50 mb in 4 in 48 hours over S England. There was an overnight air frost in N and Cent Scotland and a ground frost in many parts of England overnight. A mainly cold day followed. N Scotland had some coastal wintry showers and some inland areas of Scotland were very cold with persistent frost. Rain spread across most of Ireland, England and Wales, with a drier interval following from the S later in the day. Snow fell on northern hills in England while most of England and Wales was sunless. (St Helier 9.2C, Cassley -2.2C maximum, Kinbrace -5.9C minimum, Scolton Country Park 36.0 mm, Kinloss 5.5 h.)

Bands of rain moved N'wards on the 4th. Ahead of them, NW Scotland was showery, and another showery area moved in to a gap in the rain bands across N England. S England became dry, apart from a few coastal showers, with a little sunshine before the rain returned southwards to the SW in the evening - when the showery area extended into SE Scotland and Wales. There was local thunder early and late in the day in E Scotland, and at first in Cornwall. It was generally cold; there was snow over parts of Lincolnshire, East Anglia and Kent during the morning (e.g. at midday, Marham had moderate snow and a temperature of 0.3C), and on higher ground in some central and northern regions. Police Scotland reassured residents in Edinburgh after hundreds of people reported being woken by the sound of explosions just before 0500 GMT. However, police said that what people were actually hearing was the phenomenon known as "thundersnow". The snowfall also caused issues on the area's roads, with the Queensferry Crossing closed for several hours in both directions in the morning because of falling ice and snow. In the Highlands several schools were closed for the day, affecting almost 2,000 pupils. A small number of schools in Aberdeenshire, Moray and Dumfries and Galloway were closed due to the adverse weather. (Magilligan 9.0C, Leek 1.6C maximum, Altnaharra -9.6C minimum, Chillingham Barns 42.8 mm, Cork Airport 4.8 h.)

On the 5th after overnight rain and showers, with some snow mainly on northern hills and local thunder in E Scotland, most places became dry with sunny spells. There were, however, still some coastal showers, and more persistent rain edged E'wards across southern coastal counties of England. Heavy rainfall overnight caused extensive flooding in parts of Scotland, with train and tram lines being engulfed by water; services between Aberdeen and Inverness were suspended after a landslip near Huntly. Train services were also affected by flooding on the line at Livingston and at Hartwood in North Lanarkshire. Tram lines in Edinburgh were swamped with water near Edinburgh Airport and between the Gyle Centre and Edinburgh Gateway. (Bridlington 10.2C, Braemar 1.6C maximum, East Malling -1.6C minimum, Hurn 34.4 mm, Shoeburyness 5.9 h.)

Overnight into the 6th rain (with a little snow in places) moved S from E Scotland and NE England into the Midlands, with a separate rain area over SE England. Much of the rain died out during the morning, although there were still coastal showers. Away from the rain, there was some frost and a few fog patches at first, and the fog persisted all day in parts of the Midlands, SW Scotland and Northern Ireland. There were some brighter areas, but it was mostly rather cold. In foggy areas in Northern Ireland temperatures remained below 0C during the day. (Scolton Country Park 10.8C, Castlederg -1.3C maximum, Tyndrum -4.9C minimum, Chillingham Barns 17.8 mm, Tiree 6.1h.)

on the 7th there was widespread fog, freezing in places, at first over Cent and E England, with a few patches elsewhere. The fog thinned only very slowly, leaving a very cold, dark day. Temperatures were nearer normal elsewhere, under mostly cloudy skies, although there was some sunshine, mainly in W Scotland and NE Ireland. Showers affected some coastal areas, and moved inland across SE England during the afternoon and evening, whilst an area of rain moved W'wards into Scotland and NE England. (Isles of Scilly 9.7C, Santon Downham -0.7C maximum, Tulloch Bridge -5.4C maximum, Fyvie Castle 14.2 mm, Morecambe 6.4 h.)

Low pressure was centred over or close to N Scotland throughout the 8th. Rain affected Scotland in particular overnight, whilst there were showers near some other coasts. Much of Cent and E England became foggy again, with a slight frost in many places. There was also an air frost across much of Cent Ireland. One or two fog patches persisted all day, chiefly over Norfolk and Suffolk, but it mostly cleared to allow some sunshine. Meanwhile, the rain area traversed much of England and Wales, except the more S'ly areas, by late evening. Showery weather followed in the north. Fog and frost returned to SE England and East Anglia for a time ahead of the rain. (Isles of Scilly 9.7C, Houghton Hall 0.4C maximum, Little Rissington -4.3C minimum, Aviemore 27.0 mm, Weybourne 6.5 h.)

A few places in the SE corner of England and in E Ireland had an air frost into the 9th although most areas were cloudy overnight and during the day. Overnight rain cleared E'wards from E England, and there were a few fog patches at first in the E. The day brought a few coastal showers in the E, and rain moved across Ireland, Wales and into the W half of England and Scotland by mid-evening. 24 mm of rain fell at Valentia in the period 0600-1800 GMT. (Isles of Scilly 11.8C, Lake Vyrnwy 3.5C maximum, Frittenden -2.5C minimum, Camborne 20.4 mm, Kinloss 2.2 h.)

The 10th was a generally cloudy day with areas of light rain and drizzle. A further area of rain spread across from W Ireland and through to E England and E Scotland by late evening; this rain was heavy in places. (Isles of Scilly 12.0C, Dalwhinnie 4.0C maximum, Eskdalemuir 0.5C minimum, Cardinham 20.2 mm, Yeovilton 2.6 h.)

Low pressure centred to the W of Scotland on the 11th pushed areas f frontal rain across all areas overnight and into the morning, with the rain being followed by showers in most W areas. The day was mainly cloudy, away from a few areas of S England, the Midlands and S Ireland. Patches of mist and fog formed in parts of England and Wales in the evening. (Swanage 12.6C, Salsburgh 5.2C maximum, Fylingdales 3.3C minimum, Craibstone 33.6 mm, Cork Airport 2.4 h.)

There were further outbreaks of rain and showers into the 12th across the British Isles, although falls across most of England tended to be slight away from W areas. Much of Scotland (away from the SW) and E England had a cloudy day but it was quite sunny in parts of S Ireland. Areas of rain moved E'wards across Scotland and N England, clearing most areas in the evening. Further cloud and rain spread into W areas of Ireland in the evening. (Swanage 10.7C, Dalwhinnie 4.9C maximum, Katesbridge -0.9C minimum, Redesdale Camp 13.6 mm, Casement Aerodrome 7.0 h.)

There was a slight inland air frost in parts of England into the 13th, but it was cloudy overnight further W. Rain across Ireland overnight spread to all areas of the British Isles during the day. It slowly became milder from the SW, with the rain turning showery from the SW later, with isolated thunder near W coasts of England and Wales during the evening and night, when it was also windy in these areas.

The Needles, on the Isle of Wight, saw gusts that reached 106 mph. Train operators reported delays across S England; South Western Railway said heavy rain had "flooded the railway" between Bournemouth and Southampton, meaning cancellations and delays are expected all day. South Western, Southeastern Railway and the London Overground all reported fallen trees and other debris blocking lines and causing disruption in various locations. The ports of Dover and Calais warned Channel crossings had also been affected by the weather, with strong winds and poor visibility leading to a "risk of delays". In Wales, Western Power said the storm had caused power cuts to around 21,000 homes. Sporting events also experienced disruption, with the Welsh Grand National at Chepstow being called off due to a waterlogged course. At 1500 GMT snow lay 11 cm deep at Tulloch Bridge. (Guernsey Airport 10.0C, Braemar 0.7C maximum, Aboyne -2.9C minimum, Herstmonceux 34.2 mm, Lyneham 5.8 h.)

The 28th dawned after a frosty night, although this was mixed with wintry showers in places, especially the W and extreme SE; there was thunder over Cornwall and the Channel Islands. Freezing fog patches formed over parts of Cent and N England and N Wales, and proved quite persistent in places - as did frost in various Scottish glens. A more organised area of wet snow moved SE'wards into the W Midlands towards Cent S England early in the day, with several centimetres of snow in places, especially over north Staffordshire and parts of the Cotswolds; it slowly weakened, and turned to rain and sleet, as it headed towards the English Channel during the day. Otherwise, it was a cold, fairly cloudy day for most with further, mainly coastal, showers. Heavy snow in the Midlands led to police warning drivers they should only take to the roads for essential trips. Cars were abandoned and roads shut in Stoke-on-Trent after up 8 cm of snow fell. Rail services were also disrupted. Authorities in Staffordshire and Gloucestershire urged people not to travel unless absolutely necessary. There were reports of delays, stranded motorists and abandoned cars on the A53 at Etruria and in Hanley, in Stoke on Trent, with more issues on the A34, in Stone, and on the A500.

On the 29th, as well as the continuing coastal showers, an area of snow, turning later mostly to rain, moved SW from NE England across Manchester and Liverpool, much of Wales, the western Midlands, Somerset and Dorset from early morning to early evening. Most other areas were dry and quite cold, after a frosty start for many; there were some brighter intervals, and it was quite sunny over southern Scotland. Freezing fog formed over the snow over N Staffordshire and N Cheshire in the evening; it largely dispersed during the night. Heavy snowfall across parts of Yorkshire led to motorists being urged to avoid unnecessary travel. The A169 between Whitby and Pickering was closed due to snow and officers in North Yorkshire said driving conditions were "treacherous". Snowfall across Yorkshire also affected public transport in some areas. (Isles of Scilly and Valentia 7.8C, Drumalbin 0.9C maximum, Tulloch Bridge -7.7C minimum, Fylingdales 20.8 mm, Leuchars 5.2 h.)

There were further wintry showers, especially over Scotland where several centimetres of snow accumulated in places. An area of rain moved SE across SW Britain, the Isle of Wight and Channel Islands, and the extreme SW was quite mild. Otherwise, it was dry with some sunshine. At 1800 GMT the snow depth at Loch Glascarnoch was 22 cm. (Isles of Scilly 10.3C, Carlisle -2.2C maximum, Dalwhinnie -10.2C minimum, Kinlochewe 15.8 mm, Boulmer 6.1 h.)

On the 31st there were showers in the SW and N, and a longer period of rain or sleet, with hill snow, moved slowly SW across much of Scotland and Northern Ireland, reaching N England in much weaker form in the evening. After a frosty start over much of the country, maximum temperatures were very variable: quite large areas of England and Wales were very cold, even with a persistent frost and isolated persistent freezing fog patches, under a very low inversion and stratus. Some places, though, especially in the Midlands and Cent S England, were quite sunny and rather less cold - as it mostly was in the cloudy north and far southwest. Many of the previously sunny areas became foggy in the evening e.g. Brize Norton maximum temperature 4.7C, but by 1800 GMT the temperature was down to -2.6C under thick fog. At 0300 GMT the snow depth at Loch Glascarnoch was 21 cm. (Valentia 7.5C, Wainfleet -0.9C maximum, Topcliffe -7.5C minimum, Aviemore 27.0 mm, Almondsbury 7.0 h.)
