British Isles weather, January 2016

Low pressure pushed an area of wind and rain into the British Isles on the 1st as the day progressed. The day began with a widespread ground frost and with an air frost in many areas - the first air frost since November in parts of S England. There were a few showers overnight across Scotland - and in some SW parts of Ireland and the UK. Rain and drizzle spread across most areas from the SW during the day - preceded by sleet and snow in places as the rain met existing cold air. Only in parts of E England and on Shetland was there any sunshine. (Isles of Scilly 11.9C, Dalwhinnie 1.9C maximum, Shawbury -2.8C minimum, North Wyke 21.4 mm, Lerwick 3.5 h.)

A low pressure system on the 2nd (991 mb close to Bristol at 1200 GMT) drew mild air across the area from the S - but let to a day with widespread, and frequent, rain and drizzle. Falls were generally slight across N Scotland after a largely dry night here - but it was a dull day everywhere. (Trawscoed 12.8C, Balmoral 5.9C maximum, Dalwhinnie 1.4C minimum, Craibstone 29.0 mm, St Athan 0.6 h.)

A new area of low pressure (centre 971 mb close to W Ireland at 2400 GMT) brought further spells of rain to all areas on the 3rd. Falls were heavy in parts of E Scotland and S England and the rain was followed by showers and brighter conditions from the SW later in the afternoon and evening. Away from these showery areas it was generally dull day. (Isles of Scilly 11.6C, Lerwick 3.8C maximum, Upper Lambourn 2.5C minimum, Aboyne 37.2 mm, Casement Aerodrome 2.3 h.)

Low pressure remained slow-moving over central parts of the British Isles on the 4th, leading to another cloudy day. MSL pressure was down to 977 mb at 2400 GMT off Anglesey. Early mist and fog patches in parts of E and NE England soon cleared - overnight rain fell in E and S Scotland and in some W areas of the UK. Showery conditions affected many areas during the day - with more persistent rain in E areas of Scotland. After a mild night in all areas the temperature rose to 11C in parts of S England - but it felt cooler in N Scotland in a brisk E'ly wind. (St James Park 11.1C, Braemar 3.2C maximum, South Newington -0.3C minimum, Aboyne 42.6 mm, Heathrow 3.2 h.)

A slack area of low pressure remained centred over the British Isles on the 5th. Overnight it remained frost-free at low-levels with spells of rain or drizzle in many areas; fog and mist formed in parts of S England and the S Midlands. During the day some heavy rain fell in parts of E Scotland and NE England - with falls also across S Scotland and N Ireland. It was cool in an E'ly flow across N Scotland but mild in S districts. The best of any sunshine was to be found in S parts of England and Ireland - elsewhere it was a dull day. (Swanage, St Helier 11.2C, Braemar 2.2C maximum, Balmoral 1.1C minimum, Kielder Castle 48.4 mm, Odiham 3.2 h.)

Low pressure over the British Isles moved away to the E early on the 6th, but by 2400 GMT a new centre - 974 mb - was located over W Ireland. Mist and fog became widespread across E and Cent England before dawn - while other areas saw some falls of rain, notably locations in E Scotland and NE England. There were further falls here during the day - mainly light - while further frontal rain spread into W Ireland in the afternoon. Valentia reported 13 mm in the 12 hours ending 1800 GMT. Mist reformed widely across England in the evening - after another mostly dull day. (Isles of Scilly and Langdon Bay 11.3C, Balmoral 2.8C maximum, Derrylin Cornahoule -0.6C minimum, Chillingham Barns 21.2 mm, Yeovilton 4.0 h.)

As a depression moved E'wards across central areas of the British Isles on the 7th a W'ly flow was introduced in the S from the W. Across N Scotland a cooler E'ly flow persisted during the day. Rain moved NE'wards across all but N Scotland by dawn, with heavy falls in parts of Ireland overnight; 40 mm fell in 12 hours ending 0600 GMT at Ballypatrick Forest while 68 mm fell in 24 hours ending the same time at Dyce. Rain turned to snow over high ground in Scotland close to the E'ly flow of cold air, while the rain was followed by cooler, showers conditions from the W; many E parts of England remained dry once the early rain had cleared. The best of the sunshine was to be found across Ireland and in S and W parts of Wales and England in the showery airstream. (Manston 11.5C, Baltasound 3.2C maximum, Baltasound 0.7C minimum, Fyvie Castle 53.4 mm, Hurn 4.9 h.)

Following a widespread ground frost and an air frost in some inland areas of the UK, further areas of rain moved NE'wards during the 8th - this turning to snow in parts of Scotland where it was a cold day in many places. The rain was heavy overnight in parts of Wales and SE Ireland - with further heavy falls during the day in N Wales and SW Scotland. Two of Scotland's five mountain snowsports centres opened some runs following snowfalls and freezing temperatures. CairnGorm Mountain and the Lecht in Aberdeenshire have made runs available to skiers and snowboarders. Glencoe Mountain said it has plenty of snow for sledging, but needs more before it could open fully to snowsports enthusiasts. Nevis Range and Glenshee also require further snowfalls to open fully. Water levels on the River Don in north east Scotland reached their highest levels in 45 years during a night of severe floods caused by heavy rain. Almost 70 properties were evacuated, including the 86 residents of three care homes in Aberdeen. The River Ythan also burst its banks, with flow levels breaking previous records at Ellon. On Thursday night, Aberdeenshire Council said it was dealing with an escalating emergency response as the rivers Dee and Ythan burst their banks. Some 38 properties in Port Elphinstone, near Inverurie, and 18 homes in Ellon were evacuated. By this afternoon, Aberdeen City Council said it had switched its anti-flooding efforts to Culter, where the burn burst its banks and 12 residents from the Millside were evacuated from their homes. Un places roads were also blocked by snow. (Plymouth 11.6C, Dalwhinnie -0.8C maximum, Tyndrum -4.0C minimum, Capel Curig 56.4 mm, Manston and Casement Aerodrome 5.5 h.)

The 9th was a generally dull day. After a widespread ground frost - with an air frost in many parts of Scotland and N Ireland further areas of rain spread NE'wards, especially over England, Wales and Ireland. Across Cent Scotland the rain turned to snow in places when it reached here - and with MSL pressure down to 969 mb close to Anglesey at 2400 GMT it was a windy day in many places. (Swanage 12.0C, Balmoral -0.7C maximum, Braemar -7.7C minimum, Libanus 28.0 mm, Dublin Airport and Casement Aerodrome 0.9 h.)                                

Air pressure remained low during the 10th with rain affecting most areas of the UK overnight and a persistent line of rain across N Scotland for much of the day. Elsewhere, rainfall occurred in bands that generally migrated N'wards - with some heavy falls in S Scotland. It was a windy day with gusts over 50 mph in places. Snow fell in places from N England to Cent Scotland. Once the overnight rain had cleared parts of Ireland and Cent England had a sunny day - but much of Scotland remained dull. (Isle of Portland 10.6C, Salsburgh 2.6C maximum, Balmoral -0.9C minimum, Wick Airport 49.8 mm, Waddington 6.3 h.)

During the 11th low pressure gradually moved away to the E from the UK, introducing a N'ly flow from the W. Many places had a ground frost overnight - although there was some rain in S and E England that turned heavy in places for a while. This rain gave way to mist that the lingered for much of the day. Most places were cloudy, except in and close to SE Scotland, and there were widespread showers across Ireland, and across W and Cent Scotland that fell as snow in places. It was a cool day in many N areas. (Isles of Scilly 10.0C, Durham 1.3C maximum, Redesdale Camp -2.7C minimum, Tyndrum 26.6 mm, Boulmer 5.6 h.)

A showery, N'ly airflow persisted during the 12th. Many places had an overnight ground frost and there was an air frost in NE England. While S areas remained largely dry and generally had the best of the sunshine, further N showers fell more widely, turning to snow over high ground in Scotland. Heavy falls in Wales were accompanied by hail and thunder in places. (St Helier 9.3C, Shap 2.8C maximum, Topcliffe -2.3C minimum, Capel Curig 24.6 mm, Shannon Airport 6.0 h.)

A shallow low pressure system crossed Ireland on the 13th; after some overnight air frost in N areas and showery outbreaks further S, outbreaks of rain spread E'wards during the afternoon and evening. This rain turned to snow in places on its leading edge as it met cold air over high ground in Scotland and N England. It was a cloudy day across Ireland, but brighter further E ahead of the rain. (Plymouth 10.0C, Balmoral 0.6C maximum, Tulloch Bridge -4.8C minimum, Capel Curig 19.2 mm, Dyce 4.3 h.)

There was a widespread ground frost on the 14th as a N'ly flow set in from the N - and parts of N and Cent Scotland had a severe air frost as a result. Further S, rain, sleet and some snow cleared E'wards overnight. A showery day followed, with sleet and snow falling in places as far S as Dublin, S Wales and Suffolk. Snow showers continued into the evening in parts of Ireland and Wales - it was a blustery day in all areas at times, especially in the E. There were gusts to 67 mph at Weybourne and snow lay 16 cm deep at Spadeadam. (St Helier 8.8C, Redesdale Camp -0.3C maximum, Aviemore -7.2C minimum, Loftus 20.6 mm, Glasgow 6.0 h.)

Pressure rose from the SW on the 15th (1032 mb at Valentia by 2400 GMT) - with a N'ly flow across all areas as a result. Many areas had an early air frost with overnight showers in the W close to seaward-facing coasts. Further showers continued in these areas during the day, while a more general area of rain, with snow over N Ireland, moved towards Wales and the Midlands. 6 cm of lying snow was reported at Lough Fea. Daytime temperatures were below 5C in many areas - but rose in SW Ireland later in the day due to an approaching warm front. The first real cold snap of the winter has caused problems on the roads and led to the closure of two schools in Northern Ireland. Overnight snowfalls and freezing conditions meant people living on higher ground and in more isolated areas of Ireland were worst hit, particularly in County Tyrone and across the NW of Ireland. (Valentia 8.7C, Carterhouse 0.7C maximum, Kinbrace -6.0C minimum, Ballypatrick Forest 22.6 mm, Wittering, Shoeburyness and Manston 7.3 h.)

High pressure (1024-1028 mb in many places for much of the day) on the 16th resulted in a widespread inland air frost (sharp in Cent and N Scotland) early in the day. A weak front brought an area of rain - and for many, snow - SE'wards from Scotland to NW England and into parts of SE England before midnight. It persisted for some time, especially close to high ground, giving measureable depths in many places. 10 cm of snow was reported lying at Eskdalemuir. There were snow showers during the day in N Scotland with some rain and drizzle in parts of Ireland. Fog patches were also a problem at times in Ireland. Away from W and S Ireland, and SW England and S Wales, it was a cold day; it was a sunny day in E and S England ahead of any rain or snow. (Isles of Scilly 9.9C, Kinbrace -3.3C maximum, Kinbrace -9.9C minimum, Altnahinch Filters 15.0 mm, Wattisham 6.6 h.)

Snow moved SE'wards over the Midlands and SE England until mid-morning on the 17th; there was an air frost in Scotland and E England but the night was milder further W. SW Britain had a mild day with some outbreaks of rain; it was a mild day across Ireland but cold elsewhere. Snow depths in the snowy areas were sometimes as much as 5 cm - but in SE England 1-2 cm was more common where the event was the first snowfall of the winter for some. The mild air spread slowly E'wards during the day, ahead of a low centre off S Ireland (998 mb at 2400 GMT). Away from NE Scotland and parts of E England it was a dull day. The weather caused flight delays at Manchester and Gatwick airports, while police warned drivers to take care in the icy and snowy conditions. (Isles of Scilly 10.6C, Resallach -0.7C maximum, Kinbrace -11.8C minimum, Dundrennan 7.4 mm, Wattisham 4.8 h.)

Shallow low centres close to SW England on the 18th led to mild weather here and in S Ireland; the Channel Islands were about 6 degC cooler, however. There was an early air frost across many parts of Scotland - elsewhere it was cloudier with spells of rainfall overnight. During the day many regions - except parts of the E - had spells of rain with some snow in places, particularly over high ground in Scotland. Away from E England and N Scotland it was a dull day. (Isles of Scilly 11.6C, Kinbrace -0.9C maximum, Kinbrace -7.3C minimum, Plymouth 23.8 mm, Lerwick 4.6 h.)

Mist and a few fog patches were widespread by dawn on the 19th - which began with a widespread air frost in N and E Scotland, and in East Anglia, the Midlands and much of S England away from the SW. In both N Scotland and Cent S England the frost was sharp in many places. The mist and fog persisted all day in places, keeping temperatures on the low side. High pressure meant little precipitation except for some wintry showers close to N and E coasts. Once early mist or fog had cleared much of S England, but not the SW, had a sunny day. (Isles of Scilly 9.0C, Aviemore -0.9C maximum, Kinbrace -12.4C minimum, Spadeadam 12.8 mm*, Filton and Yeovilton 6.8 h.) * - probably due to melting snow.

High pressure early on the 20th led to widespread mist and fog across England, Wales and S Scotland by dawn. There was a widespread air frost in NE Scotland and across many parts of Cent and S England and S Wales - severe in places. It remained misty all day with fog persisting in places during daylight hours - leading to sub-zero maximum temperatures in these spots. Sherkin Island reported 8 mm of rain in the 12 hours ending 1800 GMT as warm fronts spread rain into Ireland in the afternoon; elsewhere the day was mainly dry apart from some light showers that fell in a few coastal areas. (Valentia 10.9C, Hereford -2.2C maximum, Kinbrace -11.6C minimum, Kinbrace 3.8 mm*, Yeovilton 7.7 h.) * - possibly due to melting snow.

Ground frost was widespread across England, Wales and Ireland into the 21st, as were misty conditions. E and Cent parts of the UK had a widespread air frost - Ireland was cloudier overnight with rain and drizzle as warmer air spread E'wards here - and later into W parts of the UK. Mist in the E was slow to clear - but cloud spread from the W during the day and by midnight rain and drizzle had fallen in many parts of mainland Scotland, Wales and W England. It was a mostly dull day except in SE England. (Shannon Airport 12.6C, Redesdale Camp 1.4C maximum, Loch Glascarnoch -8.2C minimum, Murlough 22.0 mm, Manston 4.3 h.)

Cloud and rain spread from the W during the 22nd, bringing milder air from the W - the overnight minimum temperature at Finner was 11.7C. Brighter and showery weather followed the rain and daytime temperatures reached 10-12C in many areas of the British Isles. In the evening another area of rain affected parts of N Ireland and W Scotland. Flood warnings were in place across parts of Tayside as persistent and heavy rain swept across the region. The River Nith had flooded into part of the West Car Park at Whitesands in Dumfries. River levels around Crieff and Bridge of Earn were expected to peak between 1100 and 1500 GMT, but Sepa said that melting snow would keep them high. (Exeter Airport 13.9C, Fylingdales 6.7C maximum, Kinloss 0.8C minimum, Capel Curig 32.8 mm, Dublin Airport 5.3 h.)

The 23rd brought a mild flow from the SW to all areas - there was a misty start to the day in S and Cent England but no overnight air frost in most areas. Rain cleared N Ireland and NW Scotland in the morning, but further rain moved E'wards across much of the British Isles during the afternoon and evening. Away from E areas of the UK it was a dull day. (Bude 13.2C, Dalwhinnie 6.9C maximum, Frittenden -1.0C minimum, Loch Glascarnoch 20.8 mm, Kinloss 4.3 h.)

The 24th dawned after a mild night with minimum temperatures above 11C in SW Ireland and S Cornwall. Rain and drizzle was widespread overnight as a warm sector pushed N'wards. Maximum temperatures were as high as 13C in much of Scotland and above 14C in many parts of S England - despite it being a dull day in most areas. 15.9 C at Keswick and Oxford and similar temperatures elsewhere (15.8C at Prestatyn and 16.5C at Achnagart) were among some of the highest January temperatures on record at these places. (Achnagart 16.5C, Fair Isle 9.3C maximum, Cassley 1.1C minimum, Capel Curig 25.4 mm, Shoeburyness 1.6 h.)

A mild S'ly warm sector led to a mild night into the 25th (minimum temperatures overnight included 13.8C at Kinloss, 13.6C at Carlisle and 13.3C at Magilligan. A cold front spread rain across all areas during the day and introduced slightly cooler air - but not until the temperature had again reached 13-15C in places. (Lossiemouth 15.6C, Fair Isle 9.9C maximum, East Malling 5.9C minimum, Cluanie Inn 25.8 mm, Shoeburyness 4.8 h.)

In most places the 26th was a dull day. A rapidly-moving and deepening area of low pressure (MSL pressure around 976 mb on Uist at 1200 GMT) brought an area of rain and windy conditions from the SW during the day; later the trailing cold front and associated rain moved S'wards as a wave development spread towards W Ireland (centre 993 off Belmullet by 2400 GMT). To the south of this rain it was a mild day and remained windy. Falls were heavy over many areas of high ground in Scotland and Wales. There was a gust of 71 mph at Loftus with one of 83 mph at Capel Curig while mover high ground in N Scotland there was snow for a time after the onset of rain. Flooding at Kirkconnel in Dumfries and Galloway affected trains running between Glasgow and Carlisle. Strong winds at high tide led to some localised flooding and the closure of a number of promenades on the Isle of Man. Debris was thrown by waves on to many promenades, including at Douglas, and a number of trees were uprooted. Earlier, ferries to and from Lancashire and a number of flights were cancelled as winds of 75 mph hit the island. (Murlough 14.8C, Lerwick 8.7C maximum, Kinbrace 1.6C minimum, Capel Curig 67.8 mm, Kinloss 4.3 h.)

Fronts were slow to clear the UK on the 27th as a deepening wave depression ran along one of them, leading to a wet spells during the day in many areas. However, parts of E England and East Anglia remained dry - and temperatures reached 14-15C here for a time after there had been overnight minima of 10-12C in parts of England and Wales. In the colder air behind the fronts there were falls of snow in parts of Scotland later in the day; maximum temperatures here were closer to 3-5C in places. It was dull over Cent and S England and in Wales - but sunny spells developed elsewhere after the rain cleared. A driver stuck in flood water has been rescued by firefighters after Storm Jonas brought heavy rain to parts of Wales. Crews freed the car on the A4069 between Llangadog and Llandovery, Carmarthenshire, after the River Bran burst its banks. In mid Wales, the Dyfi River has burst its banks near Machynlleth, Powys. (Coningsby 15.1C, Balmoral 2.5C maximum, Loch Glascarnoch 0.1C minimum, Threave 40.0 mm, Morpeth Cockle Park 3.1 h.)

Showers moved across W areas of Scotland and in N Ireland early on the 28th - with falls of snow over high ground. There was a touch of air frost in a few places before dawn before an area of rain spread from the SW during the day across many areas - giving heavy falls over hills and introducing milder air in a warm sector across Ireland by midnight. Much of England and Wales, and e Scotland, had sunny spells before the frontal cloud arrived - elsewhere it was a cloudy day. (Cork Airport, Valentia and Isles of Scilly 11.1C, Dalwhinnie 5.6C maximum, Charlwood -1.5C minimum, Capel Curig 38.8 mm, Shoeburyness 7.4 h.)

Overnight into the 29th rainfall was largely confined to Ireland, Scotland and Wales. During the day Wales, S and Cent England and East Anglia saw further light rain and drizzle; elsewhere it was mild with some showers. Later in the day a cold front spread SE'wards across Scotland and through Ireland bringing a fall in temperature accompanied by snow over high ground in Scotland and showery conditions. Parts of N Scotland had isolated thunder, while gusts of 105 mph occurred at Lerwick while gales brought disruption to N Britain. At 1200 GMT MSL pressure was down to 964-968 mb over Shetland. The system responsible was named Storm Gertrude - it resulted in a gust of 80 mph at High Bradfield, 85 mph at Orlock Head and 78 mph at Lake Vyrnwy. Up to 15cm of snow was recorded in places above 300 m. The weather led to schools being shut, power cuts, bridges closing and delays across Scotland's transport network. (Donna Nook 13.9C, Dalwhinnie 4.9C maximum, Dalwhinnie 3.0C minimum, Kinlochewe 70.8 mm, Dyce 5.6 h.)

The 30th dawned with a ground frost across much of Scotland and Northern Ireland - with an air frost in places and with falls of sleet and snow here. A brisk W'ly flow dominated the weather across the British Isles; a clearing cold front gave a wet night across England and Wales and a cold, showery day then followed in most areas - particularly across Scotland and Ireland. Showers fell as hail, snow and also gave some thunder, together with squally winds. Most places had some sunny intervals. There were further gales in the Northern Isles, and a snow depth of 6 cm was measured at Aviemore. The police said driving conditions are hazardous on many roads across Northern Ireland. (Swanage 9.3C, Braemar 0.8C maximum, Braemar -2.3C minimum, Cassley 21.6 mm, Leeming 5.6 h.)

Snow showers continued overnight into the 31st across Scotland, where there was an air frost in places. Further S, rain and drizzle edged N'wards across Ireland, Wales and England before dawn - later spreading N'wards into Scotland, although it was a cold day here in N areas with the snow turning to rain later in the evening in Cent areas. Sunny intervals developed in S England later once early rain had cleared. (Pershore 14.2C, Kinbrace 0.6C maximum, Kinbrace -2.8C minimum, Port Ellen 19.6 mm, Lerwick 3.0 h.)

British Isles weather, February 2016

N England, N Ireland and Scotland had overnight falls of rain overnight into the 1st; further S there was a dry start to the day with overnight minimum temperatures remaining above 11C in parts of S Ireland, Wales, the Midlands and S England. Further rain fell during the day in the northern areas with some wintry falls later in the day over the Scottish mountains. Storm Henry gave windy conditions with gusts over 80 mph across Scotland later. Storm Henry's high winds blew off part of the roof from a block of flats in Broughty Ferry, Dundee. Elsewhere, schools closed and transport was disrupted across Scotland. Trees were brought down by the winds in parts of N England. (Hull East Park 15.1C, Kinbrace 6.3C maximum, Kinbrace -0.3C minimum, Cassley 62.0 mm, Leeming 5.5 h.)

Winds from Storm Henry prevented an air frost on the 2nd. It was wet across N Scotland and N Ireland - where snow fell at high levels, and later at lower levels in the evening. Elsewhere there were showers and sunny periods during the day with the wind and temperatures falling later in the day as Henry eventually moved away and the winds turned N'ly. Traffic Scotland said fallen trees had shut roads, and trains and ferry routes had been hit by wind and heavy rain. More than 3,000 households, mostly in the Highlands, were left without electricity overnight. Railway travel across Scotland was disrupted due to the weather. The Tay Road Bridge was closed after a gust of 91 mph was recorded, but later reopened to cars and single deck buses. In parts of Scotland and N England nacreous clouds were sighted; cold air which usually circulates around polar regions in the stratosphere (the stratospheric polar vortex) has been displaced from its usual position over the north pole to be over the UK. Found in the lower stratosphere, these clouds are mainly seen over polar regions in winter, where very cold air - at 80C and lower - condenses the small amount of water vapour present into tenuous clouds. These clouds are normally found at altitudes of around 20 km. (St Helier, Swanage 11.0C, Braemar 3.8C maximum, Drumalbin 1.0C minimum, Kinlochewe 95.2 mm, Wellesbourne 6.6 h.)

Overnight into the 3rd wintry showers fell across N Scotland over high ground in N England - by latemorning falls had occurred as far S as East Anglia although falls then became restricted mostly to N Scotland later in the day. Showers during the day were largely confined to Wales, and W parts of Scotland and Ireland - in the evening rain spread from the W across Ireland into Scotland and into W parts of the UK. Ahead of the rain there were sunny spells. (Swanage 10.5C, Loch Glascarnoch 2.1C maximum, Drumnadrochit -1.0C minimum, Lough Fea 12.6 mm, Charterhall 7.3 h.)

There were a few snow showers across N Scotland before dawn on the 4th as rain and drizzle moved E'wards across N and Cent parts of the British Isles. S parts of England remained generally dry during the day after mostly light rain and drizzle overnight. It was mostly cloudy across Ireland and Scotland - but there were a few sunny intervals later in the day in England with temperatures reaching 12C in parts of S England. (Usk No.2 15.1C, Balmoral 3.5C maximum, Fyvie Castle -1.3C minimum, Capel Curig 21.4 mm, Leconfield 3.4 h.)

The 5th was a rather cloudy day as the UK lay under a warm sector at the start of the day. During the day a cold front crossed most areas (except the SE parts of the England) from the W bringing a spell of heavy rain in places, while there were spells of light rain and drizzle in S England ahead of this front. W Ireland had some later sunshine once the rain had cleared. (Hereford 12.1C, Stornoway 6.0C maximum, Balmoral 2.8C minimum, Achnagart 35.2 mm, Connaught Airport 1.1 h.)

There was a brisk SW/W flow on the 6th ahead of another low that resulted in MSL pressure down to 966 mb over the Western Isles by 2400 GMT. There was rain in many areas overnight and rain continued to be widespread during the day with some heavy falls in parts of the Midlands, S Wales and SW England. It was a dull day except over parts of N Scotland where there were few sunny intervals. Showers followed the rain from the W in W areas later. It was a mild day in S England with temperatures reaching 1112C in places. (Heathrow and St James Park 12.6C, Dalwhinnie 3.3C maximum, Drumnadrochit -0.9C minimum, Okehampton 57.8 mm, Kirkwall 1.7 h.)

The 7th was an unsettled and windy day. Most areas had some overnight rain or showers and the night was free from frost at low levels. Rain spread E'wards across the British Isles later in the day and there was some heavy rain in S E England in the evening, along with some hail and thunder in places. W Ireland and much of Scotland were rather cloudy - elsewhere there were a few sunny intervals. (Isles of Scilly 11.7C, Carterhouse 3.9C maximum, Lake Vyrnwy 0.3C minimum, Tyndrum 40.6 mm, Manston 5.7 h.)

By 2400 GMT the MSL pressure was down to 970 mb over Shetland on the 8th as Storm Imogen crossed N areas and brought very strong winds across S areas of the UK. Sunny periods were combined with showers and spells of rain in most areas, while thunder was heard from the S Pennines to Norfolk. Rainfall was particularly heavy at times during the day in N Wales. Winds gusted to 96 mph at Needles Old Battery, 83 mph at Pembrey Sands and 82 mph at Mumbles Head. These winds brought large waves to SW coastal areas leading to hazardous conditions around these coasts. SW England and S and Cent Wales bore the brunt of the storm, with rail and ferry services disrupted and some schools closed. Waves of up to 19.1m were measured off the Cornish coast. Several homes in Cornwall were left without power including some in Sennan Cove, which was hit by large waves. At one point, about 19,000 homes were without power on Monday. Two young children were badly injured when part of a garden wall was brought down on top of them as they walked to school in Worcestershire. A special bridge to help dormice safely cross the Church Village bypass near Pontypridd collapsed and hit the windscreen of a car, causing traffic congestion. There was disruption to a number of train lines, including the cancellation of all services in and out of Cornwall after a tree fell across the tracks near Bodmin while a number of schools in Cornwall were closed because of power cuts and storm damage; several parts of Bridgend town centre were shut because of falling roof tiles. (Manston 10.5C, Spadeadam 5.1C maximum, Aboyne 2.2C minimum, Lake Vyrnwy 47.2 mm, Tiree 5.3 h.)

Winds eased on the 9th and a S'ward moving front introduced a cooler N'ly from the N as it headed S over Scotland and England during the day. Away from E England and S parts of England and Ireland it was a rather cloudy day. Some sleet fell in parts of Ireland during the day as an area of rain moved S and there were also falls later for a while in parts of Wales. It was a wet day in the Channel Islands; in the 24 hours ending 2400 GMT 21 mm of rain fell at Guernsey Airport. (Holbeach 8.7C, Carterhouse 2.8C maximum, Kinbrace -3.1C minimum, Keswick 18.8 mm, Waddington 6.4 h.)

Pressure remained low during the 10th. There was a widespread ground frost away from S parts of Ireland, Wales and England by dawn, and a sunny day then followed - although these S areas tended to remain rather dull for much of the day. Wales and W parts of Ireland were wet in places overnight; SW England, in particular, saw showery outbreaks during the day - due to a lingering weak front that was slow to move. (Swanage 10.3C, Dalwhinnie 3.3C maximum, Spadeadam -2.0C minimum, Liscombe 17.4 mm, Dublin Airport and Leeming 8.3 h.)

There was a widespread, although generally light, air frost on the 11th and the day dawned with mist or fog patches in a few places. With mostly light winds, a sunny day followed in many areas although there were snow showers during the day across N Scotland. (Gravesend 10.9C, Tulloch Bridge 1.3C maximum, Benson -5.8C minimum, Kinloss 13.8 mm, Morpeth Cockle Park 8.5 h.)

The 12th dawned in N and E England, Scotland and areas of Ireland with an air frost while central areas of Ireland and England had a few mist or fog patches. After overnight showers in some W areas there were further outbreaks of rain in N Ireland and in parts of NE Scotland - while a front introduced rain and showers into SW and later Cent S England. It was a cloudy day in most areas - but Shetland and S Scotland were generally sunny. Showers were wintry over N Scotland at times. (Isles of Scilly 10.8C, Balmoral 0.6C maximum, Dalwhinnie -10.7C minimum, Helens Bay 31.0 mm, Lerwick 7.3 h.)

There was a slight air frost in Cent and S Scotland and in E England early on the 13th while E parts of England and Scotland had outbreaks of rain overnight, as did Ireland and SW areas of England and Ireland. It was a cloudy day away from Scotland and Anglesey - while it was wet over S England, the S Midlands and East Anglia. It was a wet day in W Ireland while there were showers in NE England and SE Scotland. Across N England, the southern upland and in N England the showers fell as snow in many places. (Guernsey Airport 10.1C, Balmoral -0.1C maximum, Aboyne-6.3C minimum, Chillingham Barns 19.0 mm, Kinloss 8.4 h.)

A frontal system over S England overnight moved away to the S, after giving some rain in S England early on the 14th. There was an air frost at first across Scotland, N England and parts of the Midlands; pressure then rose during the day as a N'ly flow developed across all areas. This flow fed troughs S'wards that led to wintry showers in N Scotland and in places close to E coast areas, while a few showers followed the clearance of the front in SW England. Some snow also fell in parts of Ireland and over some high ground in N England and S Scotland. (Isles of Scilly 9.1C, Carterhouse -0.1C maximum, Braemar -14.1C minimum , Kinloss 7.4 mm, Morecambe 8.6 h.)

The 15th dawned with a N'ly flow and a widespread inland air frost. Overnight showery precipitation was largely confined to the E coast of the UK and to N and Cent Scotland - with falls of snow in both areas. Wintry falls in these places continued for a while during the day but increasing frontal cloud from the W brought rain to the Western isles by midnight. Away from E areas of the UK it was a sunny day. Snow lay 10 cm deep at Aviemore at 1800 GMT. (Killowen 9.3C, Balmoral 1.6C maximum, Katesbridge -5.2C minimum, Fylingdales 6.8 mm, St Athan 9.3 h.)

Frontal systems gradually affected the UK from the W during the 16th. Away from Ireland and W Scotland there was a widespread inland air frost with a sharp ground frost in parts of S and Cent England. Rainfall overnight in W parts of Scotland and Ireland moved E across Scotland, Ireland and into Wales and N England by midnight - there were heavy falls in places along with some wintry falls as the rain met the colder air in the E. The best of the sunshine was to be found in E and Cent England - after some early mist had cleared from E England. Scotland and Ireland were generally dull. (Kinlochewe 10.0C, Carterhouse 2.5C maximum, Braemar -8.3C minimum, Cluanie Inn 43.6 mm, Shoeburyness 8.3 h.)

An area of frontal rain moved slowly E'wards during the 17th, clearing from the W but with rain still falling in E areas of England by 2400 GMT. East Anglia had a widespread early ground frost - then remained largely dry until the evening. Brighter conditions followed the rain with a few showers, some of them wintry; the best of the sunshine was to be found across Ireland and W Scotland - and in Kent ahead of the frontal cloud. Mist formed in the evening across parts of W and N England. (Isles of Scilly 8.5C, Drumalbin 2.0C maximum, Santon Downham -1.6C minimum, St Bees Head 50.6 mm, Shannon Airport 6.2 h.)

Overnight rain and drizzle did not clear parts of SE England until midday on the 18th. Elsewhere, away from S parts of Ireland and England, there was a widespread air frost with mist or fog patches in many parts of England. Bands of showers fell in some areas - mainly in the W of the British Isles - during the day, although most places had long sunny spells. In Cent and NW areas of Scotland the showers were wintry. (Plymouth 9.5C, Salsburgh 2.5C maximum, Aboyne -6.0C minimum, Dunstaffnage 24.2 mm, Morpeth Cockle Park 8.8 h.)

After a bright start to the 19th over E and cent parts of England - along with an air frost in E Scotland and in many inland areas of England, cloud and frontal rain spread from the W to affect all areas. Initially the rain was slight but turned heavier and was then followed by showers in a brisk W'ly surface flow. There was some wintry precipitation across NW and Cent Scotland early in the day. (Isles of Scilly 11.0C, Dalwhinnie 5.3C maximum, Aboyne -5.6C minimum, Cluanie Inn 19.2 mm, Wattisham 7.3 h.)

A brisk W'ly flow persisted throughout the 20th with fronts become aligned over S parts of England, Wales and Ireland. The result was a mild but cloudy day to the S of Scotland - with showers 9some of them wintry) over N Ireland and Scotland and with more general spells of rain further S. Across N Scotland many of the showers fell as sleet or snow, with some hail or thunder in a few places. (Exeter Airport 13.2C, Dalwhinnie 2.3C maximum, Dalwhinnie 0.0C minimum, Sennybridge 25.0 mm, Dyce 6.5 h.)

The 21st dawned after a mild night across S and cent parts of Ireland, Wales and England with overnight minimum temperatures of 10-11C widely across S England. This area lay to the S of a slow-moving cold front; to the N of the front a brisk NW'ly flow developed once a wave depression had moved along the front over S Scotland. N Scotland has a showery day with further outbreaks of snow, thunder and hail. The extreme S of England remained largely dry but cloudy while other parts had spells of frontal rain and drizzle - especially over N Ireland, N England and S Scotland. It was a mild day over much of England - although NW England was much cooler. It turned windy over N Scotland. (Exeter Airport 16.0C, Dalwhinnie 2.1C maximum, Loch Glascarnoch 0.3C minimum, Capel Curig 32.8 mm, Hawarden 4.2 h.)

The 22nd dawned mild in S England with overnight minimum temperatures around 10C here in places. A cloudy day with rain and drizzle followed here as a cold front made slow progress towards the S. Elsewhere it was a bright day with sunny spells and some showers - these turned wintry over N Scotland in the evening. Despite a generally N'ly flow it was not a cold day. (St Helier 11.1C, Dalwhinnie 3.8C maximum, Dalwhinnie -1.0C minimum, Cluanie Inn 15.6 mm, Dublin Airport 8.6 h.)

A cool flow from the N on the 23rd led to a widespread early ground frost and an air frost in many places. Showers fell overnight over N parts of Scotland and Ireland in particular - with some snow over N Scotland. Further showers followed here during the day - with frequent falls of snow over N and Cent Scotland. A trough brought some showers to SE England later, but it was a day with sunny spells in all areas. (Plymouth 12.3C, Loch Glascarnoch 1.8C maximum, Carterhouse -4.6C minimum, Gogerddan 8.2 mm, Shannon Airport 9.3 h.)

Most places had an air frost early on the 24th, notable exceptions being Cornwall and parts of S Ireland. There were also some falls of snow across N Scotland overnight with some mist and fog in places in parts of England. High pressure to the W led to a N'ly flow which fed showers (frequently of snow) into Scotland and in N parts of England and Ireland. But, away from the Channel Islands, it was a sunny day. A snow depth of 5 cm was reported at Sule Skerry at 1200 GMT. (Plymouth 9.6C, Loch Glascarnoch 0.9C maximum, Topcliffe -7.0C minimum, Resallach 8.6 mm, Lyneham 9.3 h.)

A ridge of high pressure moved E'wards during the 25th - after giving a widespread air frost to all areas by dawn. Overnight there were falls of snow over N and cent Scotland - and also over high ground as far S as the Chilterns. Further showers, some of snow, continued to affect N Scotland and N Ireland during the day while a frontal system brought rain from the W into W Ireland in the later afternoon. Ireland and W Scotland had a rather cloudy day - but there were sunny spells at first further to the E. (Milford Haven 9.8C, Spadeadam 1.4C maximum, Shap -7.6C minimum, Baltasound 7.4 mm, Wellesbourne 8.3 h.)

An area of low pressure moved SE'wards towards Biscay on the 26th while fronts remained located over W and Sw parts of the British Isles. E Scotland and parts of S and Cent England had an air frost overnight - most other areas were cloudy with rain across W Ireland; there was also some heavy rainfall overnight in Cornwall. Away from N Scotland it was a rather cloudy day with further rain in SW England and across Ireland - and showers in N Britain that gave some falls of snow in S Scotland. (Isles of Scilly 10.5C, Resallach 2.3C maximum, Dalwhinnie -5.4C minimum, Camborne 18 mm, Lerwick 8.3 h.)

Low pressure to the S on the 27th produced a mainly E'ly flow across S Britain, but a N'ly one over Scotland. There was a widespread air frost across Scotland which was followed by a sunny day. Elsewhere the day was cloudier; there was widespread rain across W and S Ireland, and also Cornwall, overnight which tended to clear during the late morning. Later in the day there were a few showers in the Northern Isles. It felt cool everywhere. (Porthmadoc 8.4C, Shap 3.1C maximum, Loch Glascarnoch -9.8C minimum, Culdrose 3.0 mm, Stornoway 9.3 h.)

The 28th dawned with an air frost over Scotland, N Ireland and N England - and with a ground frost in most other areas. In N Scotland the air frost was a sharp one. Under high pressure (MSL pressure 1026 mb over Cent Scotland at 0600 GMT) there was little precipitation except in the Northern Isles; it was sunny day generally but it felt cool in the warmer S due to a brisk E'ly wind. (Aboyne 9.3C, Dalwhinnie 4.0C maximum, Loch Glascarnoch -10.3C minimum, Kirkwall 7.2 mm, Dyce 9.6 h.)

There was a widespread air frost in the UK on the 29th - although the Northern Isles, W Scotland and much of Ireland remained above 0C overnight. Frontal cloud gave overnight rain over Ireland - and this spread into W areas of Scotland and Wales during the day. After a misty start in E England there was some sunshine in parts of E and Cent England ahead of the approaching frontal cloud - which gave rain in N England, the Midlands and Cent S England in the evening. (Hampton Water Works 10.4C, Blencathra 2.9C maximum, Sennybridge -6.5C minimum, Lough Fea 19.0 mm, Shoeburyness 8.1 h.)

British Isles weather, March 2016

The 1st was a rather blustery day with spells of rain or showers in all areas - especially overnight when there were some heavy falls over the hills of Wales and W Scotland in particular. Most places remained rather cloudy after the main rain area had cleared to the SE during the morning. As it turned cooler in the evening many of the showers fell as snow over high ground in N and Cent Scotland - and to Northern Ireland just before midnight. (Pershore College 15.6C, Dalwhinnie 5.7C maximum, Pateley Bridge Ravens Nest 1.2C minimum, Capel Curig 56.8 mm, Cork Airport 5.3 h.)

Areas of low pressure developed to the E of the British Isles on the 2nd, introducing a N'ly flow to most areas during the day. There was an air frost in E and Cent areas of Scotland before dawn - while spells of rain or showers were widespread overnight, falling as snow as far S as S Wales, Cent Ireland and N England. Precipitation was widespread during the day - much of it associated with a frontal system associated with the low pressure. It was a cool day, with showers falling as hail and snow as far S as S England - there was also some thunder in places. Heavier falls of hill snow affected some northern and western districts. (Isles of Scilly 10.4C, Dalwhinnie 2.9C maximum, Altnaharra -4.5C minimum, Cluanie Inn 31.0 mm, Lerwick 7.2 h.)

A N'ly flow early on the 3rd gradually turned cyclonic as a low pressure centre headed towards Scotland from the W; centre 989 mb over SW Scotland at 2400 GMT. There was an air frost overnight from E Scotland to the N Midlands with most other areas remaining cloudy with some falls of rain or snow. The low brought rain and drizzle from the W during the day - it was relatively dry in E England until the evening. (Plymouth 11.5C, Dalwhinnie 3.6C maximum, Topcliffe -5.7C minimum, Capel Curig 21.2 mm, Herstmonceux 7.9 h.)

Low pressure to the south on the 4th drew flow from the E then N across Scotland, with a more W'ly flow in the S then giving way the a N'ly one. There was a slight air frost at first in many areas as far S as S Ireland and the day was then generally cool. N and Cent Scotland had a mostly showery day with falls of hail and snow in places. Further S there was rain overnight with some snow in places from the Midlands N'wards. Showers followed the rain from the W - with further falls of snow as far S as the Midlands in the evening. It was a sunny day, once early rain had cleared, in SE England. Heavy snow and icy conditions caused problems across the north of the UK on Thursday night and Friday morning. Snowfalls of up to 10 cm on higher ground forced schools to shut in parts of Yorkshire and Lancashire, while in Northern Ireland Ulsterbus was forced to cancel services. Leeds Bradford airport closed briefly on in the morning when 5 cm of snow had to be cleared from the runway. (Gravesend 9.8C, Leek 0.5C maximum, Altnaharra -3.4C minimum, Pateley Bridge Ravens Nest 44.4 mm, Herstmonceux 8.9 h.)

A mainly N'ly flow persisted on the 5th. Ground frost was widespread overnight across the British Isles although air frost was largely confined to places SE of a line from Hull to Exeter. Mist and fog patches formed in this latter region - further W it was a showery overnight. Showers affected many places during the day with some hail and snow as far S as S England. Ireland and W areas of the UK had the sunniest conditions. (Usk No.2 9.8C, Carterhouse 1.6C maximum, Little Rissington -4.2C minimum, Carterhouse 16.6 mm, Glasgow 9.5 h.)

A weak ridge of high pressure on the 6th led to a widespread air frost by dawn away from coastal areas. There were further showers in many places during the day - with snow over high ground, particularly in N and Cent Scotland. In the evening, a weak front gave some rain and drizzle in W Ireland after a rather cloudy day here. The best of the sunshine was generally to be found in E areas during the day. (Swanage 9.5C, Balmoral 1.9C maximum, Tulloch Bridge -6.0C minimum, Fyvie Castle 10.4 mm, Dyce 8.9 h.)

Away from W Ireland there was a widespread air frost into the 7th. Ireland and W areas of Britain had some cloud and outbreaks of rain at times - further E, although not on some coasts, it was a drier and sunnier day. There was some snow across N Scotland and also in some E coast areas as far S as East Anglia during the day. (Scilly and Sherkin Island 9.8C, Fylingdales 2.9C maximum, Tulloch Bridge -6.8C minimum, Marham 8.2 mm, Wellesbourne 10.8 h.)

Away from Ireland and the extreme W parts of Britain the 8th dawned with a widespread air frost. Frontal cloud soon spread from the W and a small wave-depression formed as fronts arrived from the W - centre 992 mb off N Cornwall at 2400 GMT. It was a generally cloudy day with spells of rain and drizzle in most areas - with some snow across Scotland in the morning. (Isles of Scilly 11.3C, Fylingdales 4.0C maximum, Benson -7.1C minimum, Achnagart 10.6 mm, Dyce 4.5 h.)

Low pressure over SW England overnight into the 9th pushed an area of rain across England, Wales and Ireland - with many places having heavy falls. Weaker fronts gave some rain across Scotland, with snow over high ground. It became brighter during the day over Ireland and Scotland, with further daytime falls here being of a more showery nature. Across England and Wales the rain continued, gradually moving E'wards. As a result it was a cloudy day for most of England and Wales, and it was also rather cloudy in E Scotland. Western parts of Scotland, and much of Ireland, had a sunny day, however. In parts of N and Cent England temperatures failed to reach 5C during the day - while in SW areas it was windy at first during the day. Severe flooding caused widespread disruption across parts of central England, with rail passengers stranded and many schools shut. British Transport Police formed human barriers in front of the main concourse at London Euston after trains between Rugby and Milton Keynes were cancelled. Passengers were warned people could be killed as some had fallen from earlier trains on Wednesday. A total of 46 flood warnings were in place across England and Wales. Train operator London Midland said the severe flooding in several areas had caused problems with signalling and electrical equipment, leaving it unable to run trains between Rugby and Milton Keynes. A London Midland spokesman said: "Once the floodwater subsides we are still faced with trains and train crew out of place across the network." Network Rail said flooding on train lines around Daventry, Rugby and Wolverton had delayed services between Birmingham New Street and London Euston. Trains on the West Coast Mainline were also running at reduced speeds due to heavy flooding. Fourteen schools were closed in Warwickshire and a number of people were rescued from trapped cars by firefighters due to rising floodwater. Firefighters rescued drivers from stranded vehicles in Great Alne, Wolston, Baginton and Princethorpe. There were also reports of cars stuck in Kenilworth Ford. (Stormont Castle 11.1C, Carterhouse 3.6C maximum, Kinbrace -2.2C minimum, Bedford 39.8 mm, Stornoway 9.9 h.)

Scotland, Wales and parts of NW England had an air frost on the 10th with temperatures falling below -5C across parts of NW and Cent Scotland. Light rain and drizzle continued to fall during the night from a front over E England, with misty conditions here by dawn. This rain had largely faded by dawn and a hazy day followed over much of England - with mist and fog forming in the evening. Much of E Scotland and Cent and N England had a cloudy day under low cloud - elsewhere, except in W Ireland, it was a sunny day. (Mumbles Head 13.2C, Pennerley 4.8C maximum, Altnaharra -8.1C minimum, Durham 5.2 mm, Ronaldsway 10.9 h.)

Away from Ireland and N and W areas of Scotland there was a widespread ground frost early on the 11th - with an air frost in places. Frontal cloud gave some rain in W areas of Ireland and Scotland before dawn - while mist and fog were widespread across England, Wales and S Scotland overnight. During the day the rain spread across N Ireland and much of Scotland - pushing into N England in the evening. E England remained hazy all day - but it was a sunny day across much of England and Wales ahead of advancing cloud from the W later in the day. (Plymouth 13.0C, Salsburgh 5.6C maximum, Shawbury -4.7C minimum, South Uist 21.4 mm, Shoeburyness 9.1 h.)

The 12th dawned with widespread mist and fog across England and Wales - thick enough to give some snow gains in cooler spots; there was a slight air frost in parts of Cent S England and the W Midlands. Frontal rain fell, mostly, over Scotland and N Ireland overnight - this slowly retreated N'wards during the day as pressure rose. MSL pressure exceeded 1032 mb across most of England by midnight. Despite the high pressure sunshine totals were generally on the low side due to haze and some cloud. (Giants Causeway 15.0C, Eskdalemuir 6.5C maximum, South Newington -3.0C minimum, Lusa 49.0 mm, St Athan 8.3 h.)

High pressure on the 13th (MSL pressure greater than 1036 mb by midnight across most of Scotland, N England and the N Midlands) led to a largely dry day. Places SE of a line from The Wash to Exeter had a slight air frost before dawn while there were falls of rain across the Northern Isles and a few places in N Scotland. By dawn mist and fog was widespread across England and S Scotland - leading to snow grains falling in a few places. It remained hazy here for much of the day; the rain in the Northern isles soon cleared and much of England then had a sunny day; elsewhere cloud cover was more extensive and sunshine totals were lower. (Porthmadog 16.2C, Manston 6.7C maximum, Marham -3.7C minimum, Lerwick 4.0 mm, Bude 10.4 h.)

Continuing high pressure led to another mainly day on the 14th. There was a widespread ground frost over the British Isles early in the day with mist and fog being widespread across Ireland and in the UK from S Scotland S'wards at dawn. Once the visibility improved a sunny day followed in all areas except N Scotland - although a weak front gave a few spots of rain in places. (Auchincruive 16.1C, Wych Cross 6.6C maximum, Shap -3.7C minimum, Ravensworth 0.2 mm, Tiree 11.2 h.)

Pressure rose close to 1040 mb near Shetland later on the 15th; over NE Scotland and in much of S, Cent and E areas of England there were patches of mist and fog by dawn, while Cent and E Scotland had an early air frost. An E'ly wind brought some light rain and drizzle to places close to the coast of NE and E England - and most of the E coast of the UK had a rather cloudy day even where it remained dry. Sunshine amounts tended to increase towards the W of the British Isles - and these places tended to be the warmest during the day. (Dunstaffnage 15.9C, Fylingdales 5.7C maximum, Braemar -4.3C minimum, Loftus 2.6 mm, Stornoway 11.1 h.)

There was widespread mist and fog across the British Isles by dawn on the 16th as high pressure continued to prevail. Parts of Scotland and Ireland had a ground frost overnight while some light rain and drizzle fell in parts of E England and SE Scotland before dawn. During the frontal cloud moved E'wards and there were falls of rain and drizzle in a few places as a result. Most areas, however, remained mainly dry - if rather cloudy, with the best of the sunshine in W Scotland and NW Ireland. (Tulloch Bridge 16.1C, Lentran 5.0C maximum, Shap -2.3C minimum, Wisley 3.0 mm, Stornoway 11.0 h.)

Many areas of England, Wales and Scotland woke to a misty/hazy start to the 17th under a large area of high pressure. Once this, and a widespread ground frost across the British Isles, cleared the day was a mainly sunny in most areas - although low cloud with some mist and fog patches affected many coastal areas of Scotland and NE England - giving a dull day here. Where the low cloud and mist prevailed it was a cold day. (Braemar 18.7C, Inverbervie 4.7C maximum, Shap -3.7C minimum, Morpeth Cockle Park 0.4 mm, Morecambe 11.3 h.)

Mist and fog was widespread across the British Isles by dawn on the 18th, along with an air frost in W and Cent areas of England and in much of Ireland. A little rain and drizzle fell in some E areas of the UK overnight - and again here during the day. Wales and S and cent areas of Ireland had a sunny day - elsewhere it was rather dull, and cool. (Porthmadog 14.1C, Pennerley 3.0C maximum, Katesbridge -5.6C minimum, Loftus 1.4 mm, Connaught Airport 11.1 h.)

Slow-moving fronts on the 19th made for a rather cloudy day, despite the presence of high pressure. There was mist across Ireland around dawn while light rain and drizzle affected E parts of Ireland overnight. E and S England had some further light falls during the day, before it turned drier into the evening; except for NE Ireland and S Scotland the day was a mainly dull one. (Tyndrum 12.8C, Okehampton 4.5C maximum, Tulloch Bridge -5.8C minimum, Baltasound 1.4 mm, Edinburgh Gogarbank 8.2 h.)

Parts of Scotland had an air frost into the 20th while rain fell across the Northern Isles. Further rain continued here during the day - which was generally cloud apart from parts of N Ireland, S Scotland and N England. Some light rain also affected SE counties at times. Under the cloud it was a cold day. (Strathallan 14.1C, Okehampton 3.7C maximum, Tulloch Bridge -5.5C minimum, Kirkwall 3.0 mm, Glasgow 10.5 h.)

There was light rain and drizzle at times across Scotland on the 21st - earlier, during breaks in the cloud there was a widespread air frost across Wales and in parts of E Ireland and SW England. However, away from NE and SW parts of England, a mainly cloudy day ensued due to slow-moving fronts within high pressure. (Cardiff Bute Park 13.9C, Pennerley 6.6C maximum, Sennybridge -3.5C minimum, Cluanie Inn 10.2 mm, St Athan 11.4 h.)

Many areas of England dawned misty on the 22nd - and there was a slight air frost in some places here. Light rain and drizzle continued overnight across the Northern Isles, persisting for much of the day. Away from E areas of England and Scotland it was a cloudy day - in E Scotland it was a warm day in places. (Aboyne 15.4C, Capel Curig 6.9C maximum, Benson -3.9C minimum, Baltasound 5.0 mm, Odiham 11.1 h.)

The 23rd was rather cloudy in all areas (excepting the Channel Islands) with some patchy rain that spread from the W during the day across Ireland and W Scotland. In the evening widespread mist and haze formed across England. (Otterbourne Water Works 13.9C, Lake Vyrnwy 5.6C maximum, Yeovilton -3.0C minimum, Lusa 5.4 mm, Yeovilton 4.7 h.)

Frontal rain spread from the W across Ireland and W Scotland by dawn on the 24th, then gradually remaining areas of the UK by midnight. England had dawned with widespread mist or haze - while the best of the sunshine was to be found over N and Cent areas of Scotland. It turned drier from the W in the late afternoon and evening. (Aboyne 12.9C, Liscombe 6.9C maximum, Topcliffe 0.4C minimum, Capel Curig 23.6 mm, Aviemore 3.8 h.)

The rain area cleared SE England by mid-morning on the 25th, while there were a few showers in W areas overnight. After a sunny start, N and W areas clouded over and the SW'ly wind increased in speed; fronts gave rain in W parts of Scotland and Ireland later in the day and into the evening. (St James Park 15.6C, Fair Isle 7.9C maximum, Katesbridge -0.8C minimum, Harris Quidnish 14.0 mm, Bude 11.7 h.)

The 26th was a cloudy day in all areas. Rain spread E to affect all areas as low pressure developed to the W of the British Isles. MSL pressure fell to about 966 mb over the Outer Hebrides by midnight - resulting in a windy day in all areas. The rain turned to showers from the W later in the day. (Nantwich 14.7C, Inverbervie 7.1C maximum, Santon Downham 2.8C minimum, Cluanie Inn 46.4 mm, Shannon Airport 1.2 h.)

A low pressure centre (Storm Katie) to the W of Ireland at 0000 GMT moved to Cornwall (centre 971 mb) by 2400 GMT on the 27th. As a result the day was rather cold, blustery and showery; these included occurrences of hail and thunder in places, and snow later over the Scottish mountains. Gusts of 70-80mph were recorded in the far north at first as low pressure here slowly moved away to the N. In the evening the advancing low centre brought rain across S England. (Hull East Park 12.8C, Cluanie Inn 6.3C maximum, Tulloch Bridge 0.7C minimum, Cluanie Inn 31.0 mm, Boulmer 7.6 h.)

Storm Katie moved rapidly NE'wards from Cornwall to Humberside during the morning of the 28th, taking an area of heavy rain and strong winds NE'wards with it. By dawn parts of Scotland had recorded a slight air frost, and there was some snow over high ground across Scotland and N England. Gales to severe gale force SW'ly winds affected S and SE England. As the storm passed the winds eased and most places had sunny spells - although there were some showers in W areas, which fell as hail and snow in places. . There were pressure rises of up to 14 mb in 3 hours in the wake of the depression. Storm Katie led to flights bound for Gatwick and Heathrow being diverted to other airports and dozens were cancelled as gusts of up to 106 mph hit the south of the country. More than 200,000 homes were without power at the height of the winds, with thousands still awaiting reconnection. A kayaker was feared dead after he capsized in the River Wey, Surrey. The Environment Agency issued 20 flood warnings and about 120 alerts across England in response to what it said were "rapidly rising" river levels in the wake of the storm. Travel disruption included the closure of Dartford River Crossing and M48 Severn Bridge and delays to several train routes because of trees blown on to tracks. Planes diverted from Gatwick, which had all been due to land after midnight, were also sent to Liverpool, Manchester, Stansted and East Midlands. A gust of wind dumped a stable into the front of a house in Alderney, while scaffolding collapsed following strong winds in Woodley, Reading. Trees fell on power lines in Fernhurst, West Sussex and London Fire Brigade said it had dealt with more than 110 incidents caused by the high winds. In Sussex, police say they received about 600 weather-related calls between midnight and 0830 GMT. A landslip in Templecombe shut the railway line between Salisbury and Exeter St Davids while cross-Channel and Isle of Wight ferry services were subject to delays and temporary sailing restrictions were put in place at the Port of Dover. Part of the M6 between junctions 13 and 14 was closed because of flooding. (St James Park 13.3C, Lake Vyrnwy 5.9C maximum, Drumnadrochit -2.1C minimum, Leek 37.0 mm, Aberporth 8.8 h.)

A W'ly flow on the 29th brought mainly cloud and showers conditions to the British Isles. Parts of Scotland and N Ireland had a touch of air frost before dawn while showers fell overnight in W areas of Ireland, Wales and Scotland in particular. During the day these made progress inland - becoming widespread - but all areas also had sunny intervals. Some hail and thunder occurred in a few showers, while snow fell over high ground in Scotland and N England. (Gravesend 13.8C, Lake Vyrnwy 5.4C maximum, Katesbridge -2.8C minimum, Lake Vyrnwy 20.4 mm, Boulmer 9.3 h.)

There was a widespread ground frost on the 30th with an air frost in much of N, E and Cent Scotland. There were further showers during overnight and during the day - although rainfall amounts were much reduced across England and Wales. Across Scotland showers were often wintry, while thunder occurred in the evening in parts of S England. Again, between the showers, all areas had sunny intervals. (Writtle 13.6C, Lerwick 6.7C maximum, Kinbrace -5.2C minimum, Threave 13.8 mm, Shawbury 10.3 h.)

A ridge of high pressure brought generally settled conditions on the 31st. There was a widespread earl ground frost and many areas, away from the coasts, had an air frost with places in N and cent Scotland being particularly cold at first. There were some coastal showers over Scotland - further showers during the day included thundery outbreaks in parts of East Anglia, where there was also isolated thunder. (Langdon Bay 14.7C, Fair Isle 7.1C maximum, Altnaharra -7.8C minimum, Drumalbin 7.2 mm, Bude 12.3 h.)

British Isles weather, April 2016

High pressure gave way to a frontal system from the W during the 1st. After early mist and fog in some E and Cent areas of England, and a widespread air and ground frost over most of the UK, rain spread from the W to most areas by midnight. It remained generally dry in the SE corner of England, despite clouding skies, into the evening; elsewhere it was a dull day. (Gravesend 14.1C, Carterhouse 5.5C maximum, Santon Downham -3.1C minimum, Glasgow 31.6 mm, Shoeburyness 9.8 h.)

Places SE of a line from The Wash to Dorset remained generally dry at first on the 2nd. The rain across Wales and N England overnight moved W'wards towards Scotland and Ireland. After a bright start over N Scotland it turned cloudy later with the rain returning to Cent Scotland by midnight. It was also bright in SE parts of England at first, but cloud and rain spread from the SE to affect much of the E half of England by midnight. (Holbeach 15.8C, St Bees Head 7.8C maximum, Aboyne -0.5C minimum, Whitechurch 33.8 mm, Lerwick 10.3 h.)

The 3rd was an unsettled and cloudy day in many parts of the British Isles. Rain moved N'wards overnight in E parts of the UK - followed by sunny spells here for a while. Rain also affected Scotland and Ireland overnight, while further outbreaks of rain moved NE'wards across much of the British Isles during the afternoon and evening, with thunder in SE England in the evening. As the rain cleared across Scotland and Ireland into the evening it turned rather misty in places here. (Gravesend 17.2C, Inverbervie 6.0C maximum, Baltasound -0.1C minimum, Derrylin Cornahoule 19.6 mm, Shoeburyness 8.8 h.)

Low pressure on the 4th (centres at 1200 GMT of 998 mb over SW Scotland and 999 mb off S Devon) led to a generally unsettled day. There was overnight rain and/or mist in many areas with further rain and showers during the day. In the S of Ireland and the UK precipitation amounts decreased during the day as pressure rose a little. Thundery showers occurred from the N Midlands to Humberside in the afternoon with some sunshine in these S areas. Much of Scotland remained cloudy throughout the day. (Winterbourne No.2 15.2C, Braemar 6.2C maximum, Kinbrace -0.8C minimum, Logan Botanic Garden 27.6 mm, Guernsey Airport 7.1 h.)

Overnight rain into the 5th over N Wales, N England and Scotland cleared slowly towards the E during the morning and early afternoon; elsewhere in England there was widespread mist by dawn. N Scotland remained largely dull during the day with the best of the sunshine being found across S areas of England and Wales. There were a few thundery showers in SE England later in the afternoon, while frontal rain spread across Ireland and into W Scotland and W Wales during the afternoon and evening. (Writtle 16.0C, Loch Glascarnoch 7.2C maximum, Katesbridge 0.7C minimum, Blencathra 18.2 mm, Aberporth 11.8 h.)

There was a slight ground frost in some E areas of the UK before dawn on the 6th - ahead of frontal rain that spread E'wards across the UK in the morning. The rain was followed by sunny intervals and showers in a W'ly airflow - these falling as hail and with thunder in places, and with some snow over high ground in the N. (Writtle 14.5C, Blencathra 5.3C maximum, Aboyne -2.2C minimum, Cluanie Inn 31.6 mm, Shobdon 8.8 h.)

Into the 7th rain affected much of Ireland, Scotland and Wales overnight. This rain moved SE'wards during the day, clearing SE England into the afternoon and evening. Further areas of rain and showers followed in the N and W of the British Isles, with some hail - and also thundery outbreaks in parts of N and E England in the afternoon. Snow was reported over some high ground areas in Scotland. (Carlisle 14.1C, Okehampton 7.1C maximum, Fylingdales 1.1C minimum, Capel Curig 28.4 mm, Morecambe 9.6 h.)

Mist and fog was widespread across many parts of England early on the 8th and many parts of the Uk had an early, slight, ground frost. Showers from E Scotland to N England an Cent S England slowly weakened as an area of more general rain spread from the W across Ireland and into the W half of the UK in the afternoon and evening. Skies cleared in much of Ireland in the evening behind this rain area. (Hampton Water Works 15.0C, Lough Fea 6.3C maximum, Loch Glascarnoch -2.2C minimum, Harris Quidnish 9.4 mm, Shoeburyness 7.5 h.)

Fronts crossed the UK overnight and during the morning of the 9th, while during the day winds turned to an E'ly direction around an area of low pressure to the S. Clearing skies behind the rain led to a widespread ground frost across Ireland and Wales, with an air frost in many parts of Ireland, by dawn. The rain persisted across N Scotland throughout the day but, away from here, most places had sunny spells during the day, until another band of rain moved slowly NE'wards across S and Cent area of Britain during the day; this was followed by more showery conditions to the W. Some hill snow fell in parts of Scotland. (Holbeach 12.9C, Bala 5.2C maximum, Katesbridge -4.0C minimum, Dunstaffnage 14.6 mm, Tiree 10.5 h.)

Away from N Scotland, where rain continued to fall overnight into the 10th, there was a widespread ground frost and an air frost in many inland locations. The rain in N Scotland largely cleared during the day but an area of heavy rain affected S Ireland, Wales, Cent and SW England from before dawn. 40 mm of rain fell in 12 hours ending 1800 GMT on Scilly and windy conditions in the SW led to some damage in places. The rain was thundery in the extreme SW of England. It felt cool as the wind speed increased from the S across England, Ireland and Wales. (Porthmadog 14.6C, Killylane 7.2C maximum, Shap -4.2C minimum, Isles of Scilly 54.0 mm, Magilligan 12.3 h.)

Rain in S parts of the UK overnight into the 11th moved slowly N'wards during the day, leading to drier - but misty - conditions in S England, S Wales and S Ireland by midnight. To the N of the rain it was largely dry (after a cool start) in an E'ly airflow, although winds became more variable as a shallow low formed over the N Midlands later (centre 1006 mb here at 2400 GMT). Scotland and E parts of England had the best of the sunshine - further W many areas were dull all day. (Blackpool 16.7C, Braemar 6.6C maximum, Baltasound -1.7C minimum, Lake Vyrnwy 23.8 mm, Stornoway 11.3 h.)

During the 12th frontal ran moved slowly N'wards across N England and S and cent parts of Scotland, with fall in NE Scotland in the evening. To the S of rain it dawned misty/foggy - although with long sunny spells once the visibility had improved temperatures reached 16C in parts of S England. Some thundery showers developed later in the day from Devon to East Anglia. It was also a sunny day in N Scotland ahead of the advancing rain area. (Writtle 18.1C, Salsburgh 5.3C maximum, Whitechurch -0.1C minimum, Hull East Park 41.2 mm, Guernsey Airport 12.3 h.)

Patchy mist and fog was widespread before dawn on the 13th across Ireland, Wales and England - with a touch of ground frost in m nay places here also. Overnight rain across S and E Scotland was slow-moving during the day - with falls also during the day in parts of N England. The extreme N of Scotland was generally sunny, as were much of Ireland, Wales and England - although Ireland and England clouded over later from the SW as frontal rain spread NE in the afternoon and evening in S areas. Some E parts of England had isolated thundery outbreaks in afternoon showers. (Heathrow 18.6C, Carterhouse 5.8C maximum, Sennybridge -1.8C minimum, Levens Hall 19.6 mm, Hurn 11.6 h.)

Patchy rain into the 14th fell in many areas from C Scotland S'wards and the day that followed was a mainly cloudy one. There was some early ground frost in N Scotland. Away from S England the rainfall eased off during the day - but in S and Cent areas of England, after a misty beginning, there were showery outbreaks that turned thundery in places. More extensive frontal rain spread N'wards into S England in the evening. (Gravesend 18.1C, Carterhouse 6.0C maximum, Kinlochewe -1.2C minimum, Pershore College 29.4 mm, Tiree 11.7 h.)

The 15th was a cloudy day for much of England and Wales due to widespread frontal rainfall here. Cold fronts across Scotland pushed S'wards during the day, introducing a N'ly flow in their wake. This led to falls of sleet and snow over high ground in Scotland and N England - while parts of N Scotland had an air frost early in the morning. (Plymouth 14.5C, Braemar 4.2C maximum, Braemar -0.8C minimum, Hampstead 23.4 mm, Tiree 8.4 h.)

Air frost was widespread on the 16th across Scotland and N Ireland; there was some rain across these areas before dawn that turned to snow over high ground. S England had spells of rain overnight that continued during the day - with snow in places, notably over Norfolk and Lincolnshire in the morning. Pressure rose during the day and it turned brighter in the S from the W. With winds from the N, it was a cool day. (St Helier 11.9C, Balmoral 4.4C maximum, Spadeadam -2.4C minimum, Cromer 16.6 mm, Bude 10.7 h.)

High pressure early on the 17th gave way to frontal cloud and rain from the NW as the day developed. There was a widespread early air frost and a sunny day followed across England, Wales and Ireland. It turned cloudier across Scotland with rain in the N and W here, and in N parts of Ireland, by late evening. (Killowen 13.6C, Cluanie Inn 7.4C maximum, Eskdalemuir -5.1C minimum, Cluanie Inn 6.8 mm, St Athan 12.8 h.)

Cloudy frontal conditions spread SE'wards across all areas during the 18th - but rising pressure meant that precipitation amounts were mostly slight and largely confined to N Britain. As the fronts moved S'wards sunny conditions developed to the N. MSL pressure reached 1028 mb over the Channel Islands by 2400 GMT. (Newport (Salop) 13.8C, Okehampton 7.5C maximum, Frittenden -1.1C minimum, Kinlochewe 10.0 mm, Guernsey Airport 13.2 h.)

High pressure on the 19th (MSL pressure 1033 mb at 2400 GMT close to the mouth of the River Humber) resulted in a bright and sunny day in most areas. Parts of N and Cent Scotland had an early ground frost and there was a little rain overnight in the Northern Isles. NW Scotland turned cloudier with a little rain in places later in the day. (Chivenor 16.4C, Lerwick 7.3C maximum, Dalwhinnie -2.2C minimum, Fair Isle 1.4 mm, Camborne 13.5 h.)

High pressure on the 20th resulted in a widespread ground frost and an air frost in places from N Wales N'wards. Frontal cloud led to cloudy skies across N Scotland and some light rain here in places. SW England also turned cloudy with some light rain in the evening. An E'ly wind meant it felt cool in S England, despite the prolonged sunshine here. (Porthmadog 19.2C, Fair Isle 9.4C maximum, Braemar -4.1C minimum, Lerwick 1.2 mm, Tiree 14.0 h.)

There was a misty start to the 21st in E England, with a few fog patches. Away from S England, where it was cloudy overnight with some rain in the SW and in the Channel Islands, there was a widespread ground frost. Cent Scotland and some N areas of Wales, England and Ireland also had an air frost. It remained rather cloudy in S Ireland and S England and there was some cloud and the occasional fall of rain during the day in N Scotland. Elsewhere, the day was a sunny one. (Porthmadog 20.3C, Lerwick 8.9C maximum, Tulloch Bridge -4.6C minimum, Cardinham 1.2 mm, Edinburgh Gogarbank 13.7 h.)

Pressure remained high to the W of the British Isles on the 22nd. Frontal rain moved N'wards into S England in the morning and then slowly spread into S parts of the Midlands, East Anglia, Wales and Ireland. After a cool start with an air frost in cent areas of Scotland and N Ireland, places to the N of the rain area had a day with sunny spells and a few light showers - the latter mainly in N and E Scotland. There were also a few outbreaks of rain in SW Scotland and NE England - close to the North Sea. (Porthmadog 17.4C, Okehampton 5.7C maximum, Kinbrace -5.4C minimum, Yeovilton 12.8 mm, Tiree 13.4 h.)

A cold N'ly flow on the 23rd brought an early air frost across parts of Wales, E Ireland, Scotland and parts of N England. Overnight rain in S England soon cleared away to the S while fronts moving S'wards in N areas led to falls of snow over high ground. There were long sunny spells in many areas. (Plymouth 13.5C, Balmoral 4.4C maximum, Tulloch Bridge -5.3C minimum, Fyvie Castle 3.2 mm, Bude and Shannon Airport 13.2 h.)

A widespread ground frost on the 24th was followed by a cold day in most areas. A N'ly flow was accompanied by some light outbreaks of precipitation - and a mixture of cloud and sunny intervals across the British Isles. Over high ground in Scotland there were some wintry falls. (Cardiff Bute Park 14.9C, Fylingdales 5.7C maximum, Wick Airport -3.2C minimum, Rostherne 6.6 mm, Bude 11.6 h.)

Low pressure to the E of the UK on the 25th drew flow from the N across all areas during the day. Fronts and troughs gave spells of rain to most areas at sometime during the day; after an overnight ground frost across Scotland and E England some of this precipitation turned to snow over high ground in Scotland. Many other areas also had lesser falls of hail and/or sleet/snow. (Pershore 13.9C, Loch Glascarnoch 3.8C maximum, Tyndrum -1.7C minimum, Baltasound 7.4 mm, Cork Airport 11.1 h.)

Sunny spells and showers were widespread on the 26th. Some inland areas of the UK had a slight air frost before dawn, and ground frost was widespread. Showers were generally short-lived, but the precipitation was of hail and sleet/snow in many areas - with some thundery outbreaks also. In onshore winds in the NE some of the falls of snow/sleet were long-lived. (Pershore 12.2C, Dalwhinnie 3.6C maximum, Sennybridge -3.4C minimum, Aboyne 14.8 mm, Casement Aerodrome 11.5 h.)

The 27th was another day of sunny spells and showers in a N'ly airstream, some of them wintry. Air frost was widespread early in the day while mist patches formed widely in the evening over E parts of England. (Kew Gardens 12.5C, Loch Glascarnoch 4.8C maximum, Tulloch Bridge -3.7C minimum, Weybourne 10.0 mm, Glasgow 11.0 h.)

There was a widespread air frost on the 28th, with temperatures down to -5C in parts of N Scotland. Grass minimum temperatures dropped below -10C in places here. Sunshine gave way to cloud in many areas as a low pressure centre crossed S Scotland during the second half of the day. This led to outbreaks of rain, which spread from the W; there was some heavy rain and thunder in places - and snow, heavy in places, fell over the higher ground of N England, N Ireland and Scotland. In places, snow depths reached several centimetres over parts of the Pennines and S Scotland. (Exeter Airport 13.5C, Blencathra 2.9C maximum, Kinbrace -5.6C minimum, Tiree 25.4 mm, Kirkwall 12.2 h.)

Low pressure close to E Scotland on the 29th led to a resumption of the N'ly flow - with a ground frost in parts of Scotland and N England, N Wales and N Ireland. Showers, some of them wintry, affected most areas with longer spells of rain or snow over parts of E and S Scotland and NE England. Thunder was also reported in places, notably over London in the afternoon. In between the showers most areas had sunny spells. (Writtle 12.8C, Carterhouse 3.1C maximum, Altnaharra -4.5C minimum, Redesdale Camp 19.0 mm, Tiree 12.6 h.)

There was another widespread ground frost across the British Isles on the 30th with an air frost in many inland parts of the UK. Pressure rose from the SW and the winds turned to more of a W'ly direction during the day, leading to a slightly warmer day for many areas. Further showers fell during the day; again, some were heavy with hail or thunder in places. A few snow showers were also reported. (Gravesend 14.8C, Lake Vyrnwy 7.9C maximum, Dalwhinnie -3.8C minimum, Newport (Salop) 8.6 mm, Guernsey Airport 13.9 h.)

British Isles weather, May 2016

Under high pressure, much of England had a ground frost on the 1st with an air frost in many areas. However, cloud and frontal rain soon spread to most areas from the W, although amounts tended to decrease as the rain reached E England with East Anglia and the extreme SE part of England remaining sunny for much of the day. (Gravesend 17.5C, Eskdalemuir 8.8X maximum, Santon Downham -3.3C minimum, Lusa 25.0 mm, Shoeburyness 12.0 h.)

The 2nd dawned with many areas under a warm sector, but during the day the trailing cold front crossed most areas to give a spell of rain. Minimum temperatures remained above 10C overnight in many parts of England and Wales ahead of the rain - and as the rain cleared it introduced sunny spells from the W as pressure rose. MSL pressure reached about 1026 mb on Scilly by 2400 GMT. Colder weather and some showers also followed the front; there was also some hail, snow and isolated thunder in the north. (Santon Downham 18.7C, Dalwhinnie 7.9C maximum, Loch Glascarnoch 4.5C minimum, Achnagart 52.8 mm, Shannon Airport 11.8 h.)

Parts of England and E Scotland had a slight ground frost on the 3rd. Despite high pressure (MSL pressure close to 1030 mb on the Channel Islands at 2400 GMT) troughs brought spells of rain and showers across Scotland, N Ireland and parts of N England during the day. However, there were sunny spells everywhere, although frontal rain began falling in the extreme W of Scotland later in the evening. (Frittenden 17.0C, Dalwhinnie 9.1C maximum, Exeter Airport -0.3 C minimum, Loch Glascarnoch 22.2 mm, St Athan and Jersey Airport 13.3 h.)

Much of England again dawned with an air frost on the 4th, with a dry and very sunny day the following in most places here. Outbreaks of rain affected Scotland and N and W parts of Ireland at times during the day - and a broisk S'ly flow developed here during the day. (Gravesend 18.9C, Eskdalemuir 9.0C maximum, Santon Downham -1.0C minimum, South Uist 13.6 mm, Lyneham and Wellesbourne 14.1 h.)

After a widespread ground frost in the Midlands and parts of S England on the 5th it turned quite warm here during the day - with long sunny spells for much of England and Wales. Elsewhere, parts of Ireland and Scotland had a cloudy day with some rain at times - although places from Malin Head to Inverness were largely sunny. (Northolt 21.5C, Dundrennan 9.9C maximum, South Newington -0.5C minimum, Achnagart 5.4 mm, Guernsey Airport 14.0 h.)

With light winds into the 6th, there was a widespread ground frost across the British Isles. After a misty start in places, a warm day across the S half of England followed as an E'ly flow became established around low pressure to the S. Despite extensive high cloud it was a sunny day in most areas with a few showers in parts of W Scotland. Rain spread by the low to the S of England pushed into the Channel Islands and SW England in the evening. (Northolt 23.8C, Ballypatrick Forest 10.9C maximum, Castlederg -0.6C minimum, Resallach 2.4 mm, Magilligan 13.4 h.)

There was a ground frost across parts of N Scotland on the 7th with a slight air frost in places. Many parts of England and Wales had overnight air minimum temperature of 8-12C, with a warm day then following. But, initially there were misty conditions across England and Wales with some light rain spreading N'wards across Wales, Ireland and parts of W England. A cloudy day followed across Ireland and much of Scotland with light rain. It remained misty for much of the day over England and Wales but showers over parts of southern England in the early afternoon developed into thunderstorms that moved NW'wards across the Midlands and Wales during the afternoon and early evening. (Marham 24.9C, Carterhouse 7.5C maximum, Altnaharra -1.7C minimum, Coleshill 16.0 mm, Wattisham 11.3 h.)

Mist and fog in E Scotland and NE England cleared during the morning of the 8th and a warm and sunny day then followed in most places in an E'ly airflow. Rain overnight across Wales soon cleared although there were further showers in the afternoon in some W parts of Britain and in W Ireland. Misty conditions reformed in E Scotland in the evening. (Northolt 27.1C, Fair Isle 10.0C maximum, Redesdale Camp 5.3C minimum, Sennybridge 12.8 mm, Waddington 13.9 h.)

After a mild night (minimum temperatures were in the range 10-16C overnight in much of Wales, Ireland and England - except in NE England) much of the UK was sunny and very warm on the 9th. Rain in SW England and S Ireland before dawn slowly spread N and E so that S and Cent Ireland, SW and Cent S England and S wales were rather cloudy - while it was cool near E-facing coasts. (Lusa 26.7C, Fair Isle 11.5C maximum, Braemar 0.7C minimum, Whitechurch 20.2 mm, Dyce 14.8 h.)

Frontal cloud affected much of S Ireland, England and Wales on the 10th. There was widespread in these areas overnight, which turned heavier during the day. SW England had mist and fog for much of the day and it turned generally misty across England and Wales into the evening. Scotland and the extreme N of Ireland had a warm and sunny day, while E coast areas again remained cooler in the E'ly surface flow. (Lusa 25.6C, Baltasound 9.3C maximum, Braemar 1.8C minimum, Wittering 27.0 mm, Kinloss 15.1 h.)

The 11th dawned after a mostly mild night from S Scotland S'wards, but a warm, sunny day then followed across Scotland. Elsewhere, mist, rain and drizzle cleared from Ireland during the day but lingered in other areas. There were heavy downpours in some southern counties, especially from N Surrey across into Berkshire, Oxfordshire and Wiltshire to Somerset, and over south Wales. Mist and coastal fog formed in the evening in NE Scotland. (West Freugh 23.9C, Fair Isle 10.2C maximum, Braemar 0.0C minimum, Cardiff Bute Park 39.8 mm, Lerwick 15.4 h.)

There was some rain overnight into the 12th in S Ireland and S England - along with widespread mist and fog across much of E Scotland, England and Wales. Away from S Ireland, the Channel Islands and the extreme SW corner of England a sunny day followed. Heavy showers and thunderstorms moved SW'wards across parts of Cent S and SW England during the late afternoon and evening. It was chilly near northern and eastern coasts, and sea fog affected parts of northeast England. (Porthmadog 24.7C, Baltasound 9.3C maximum, Altnaharra -1.2C minimum, Hurn 10.0 mm, Tiree 14.2 h.)

The flow turned to N'ly behind cold fronts that pushed S'wards across N areas during the 13th. Many areas of England had a hazy start to the day with sunny conditions across S areas of Ireland, Wales and England ahead of these fronts - which gave only slight falls of rain or drizzle. However, two small areas had a thundery deluge: Purbeck around the middle of the day, and the Carmarthen to Swansea area in the late afternoon. A few light showers fell from the N'ly fflow on to the E coast of the UK. (Porthmadog 22.4C, Fylingdales 7.7C maximum, Shap 0.8C minimum, Mumbles Head 1.0 mm, Valley 14.4 h.)

Many places in Scotland had an air frost (sharp in places) early on the 14th and ground frost was widespread from N parts of England and Ireland N'wards. Pressure rose from the W during the day to 1025-1026 mb over W Ireland by 2400 GMT. There were a few showers close to the E coast of the UK during the day, which was otherwise generally dry with sunny spells in most areas. (Thomastown 16.7C, Lerwick 7.2C maximum, Tulloch Bridge -5.7C minimum, Fylingdales 1.0 mm, Tiree 14.8 h.)

With continuing high pressure, the 15th was another mostly dry day. There was a little light rain and drizzle in N Scotland and some showers close to the E coast of the UK. Parts of Cent Scotland and Wales had an early air frost while an inland ground frost was widespread (except in SW Ireland). Away from W Scotland and some E coast areas of the UK it was a sunny day. (Exeter Airport 18.4C, Loch Glascarnoch 8.9C maximum, Tulloch Bridge -4.4C minimum, Loch Glascarnoch 2.4 mm, Prestwick 15.1 h.)

Although pressure remained mainly high on the 16th, N Scotland continued to be affected by low cloud and some outbreaks of rain and drizzle. There were air frosts in parts of S Scotland and N Ireland - with a slight ground frost in many other inland areas. Except across the N half of Scotland a mostly sunny day then followed. (Pershore 19.4C, Fair Isle 8.9C maximum, Katesbridge -3.2C minimum, Harris Quidnish 1.4 mm, Thomastown 14.2 h.)

A cold front continued to give outbreaks of rain and drizzle across N Scotland on the 17th; it was cold day on the Northern Isles. There was an early ground frost in many N areas, while light frontal rain reached W Ireland by dawn; much of E Ireland and S England and S Wales was misty/foggy at this time. During the day this latter area of frontal rain and drizzle moved steadily E'wards although much of E England and the extreme SE of England had a sunny day before the cloud arrived. (Writtle 19.9C, Baltasound 6.3C maximum, Redesdale Camp -0.5C minimum, Katesbridge 17.2 mm, Herstmonceux 10.0 h.)

A series of fronts associated with a low pressure centre that crossed Scotland on the 18th brought widespread rain and showers across the British Isles from the W, with rain also moving S'wards across N Scotland. The cloud meant a mainly mild night across the UK and it then turned brighter from the W as the day developed. Much of E England remained cloudy until the evening. (Edinburgh Gogarbank 17.6C, Fair Isle 7.9C maximum, Katesbridge 4.2C minimum, Drumalbin 25.4 mm, Bude 8.6 h.)

E England had a misty start to the 19th with fog in parts of NE England. However by dawn another area of rain was affecting the W half of Ireland and this then moved E'wards to affect all areas of the British Isles. Showers followed the rain - some of these were thundery close to SW Scotland. It was a rather dull day across Scotland; elsewhere there were some sunny periods once the early rain had cleared to the E. (St James Park 19.1C, Fair Isle 6.8C maximum, Baltasound 1.4C minimum, Lusa 17.4 mm, Lyneham 7.6 h.)

The 20th was a day of showers and sunny intervals, initially in the E, with further rain areas following from the W during the day. Most falls, however, were slight but it was a cool day in W areas. (Wisley 20.3C, Fair Isle 11.3C maximum, Fyvie Castle 4.4C minimum, Lough Fea 13.6 mm, Morpeth Cockle Park 8.2 h.)

Falls of rain and drizzle were widespread overnight into the 21st, gradually clearing from the W. In places, there were some heavy falls, and the rain was followed by showers from the W - mainly across Ireland. It was cloudy across much of England during the day as a frontal wave drove the rain N'wards in E areas here before it finally cleared the E coast. (Santon Downham 20.0C, Lerwick 9.3C maximum, Lerwick 4.9C minimum, Rochdale 40.4 mm, Shannon Airport 11.6 h.)

The 22nd was a sunny day in many areas - after a misty start to the day in some parts of England. It was cloudier in S and SE parts of England where there was intermittent rain and drizzle that moved E'wards, and NW Scotland was also rather cloudy. Showers developed widely during the day with some thundery outbreaks. (Gravesend 20.0C, Wick Airport 11.8C maximum, Katesbridge 1.3C minimum, Aboyne 20.6 mm, Ronaldsway 12.7 h.)

Although pressure remained generally high on the 23rd, troughs led to a few areas of rain or showers - after an early, scattered, ground frost. There were also a few early morning mist and fog patches in parts of Cent England and E Scotland. A few showers were heavy with thunder in the E Midlands, East Anglia and SE England - but there were long spells of sunshine in most areas away from N Scotland. (Wiggonholt 20.6C, Banagher Caugh Hill 11.6C maximum, Braemar -0.6C minimum, Wattisham 18.0 mm, Prestwick 14.3 h.)

High pressure persisted on the 24th (MSL pressure 1028 mb and higher over N Scotland and the Northern Isles at 2400 GMT). Sheltered areas across the British isles had a touch of early ground frost - while during the day there was cloud close to the North Sea coasts of the UK. After a misty start in parts of the UK and Ireland most areas away from the North Sea had a sunny day - although under the cloudier skies in the E there was some light rain. (Porthmadog 21.0C, Lerwick 9.1C maximum, Katesbridge -1.1C minimum, Dalwhinnie 5.6 mm, Cork Airport 15.0 h.)

Despite pressure remaining generally high on the 25th, a N to NE'ly flow led to a cool day with an area of low pressure close to NE England pushing rain and drizzle W'wards over East Anglia parts of the Midlands and later N England and S Scotland. The day began with a ground frost in places after a mostly dry night. W Scotland and parts of Ireland had a sunny day - most of England was cloudy. (Tyndrum 16.6C, Fylingdales 8.0C maximum, Shap -0.7C minimum, Loftus 13.0 mm, Tiree 15.1 h.)

Overnight into the 26th there was widespread mist (and a few fog patches across England) with light rain and drizzle in N England and N Wales, S Scotland and N Ireland. Clearer skies in S England gave a touch of ground frost here. The rain area moved little during the day, with another area of rain affecting parts of S England and the Channel Islands (with thunder on Jersey) later in the day. Over much of S Wales, S England and the S Midlands, and East Anglia it was quite sunny and warm; W Scotland was also sunny but other areas were rather dull. (Hampton Water Works 21.9C, Drumalbin 8.1C maximum, Yeovilton 1.5C minimum, Chillingham Barns 13.8 mm, Shoeburyness 13.9 h.)

Rainfall overnight into the 27th was largely confined to S England, S Wales and the Channel Islands. The frontal rain from N Ireland the SE Scotland and N England weakened. By dawn mist or fog patches were widespread in Cent and N England - these soon cleared while the rain in the S affected mainly S Wales during the day (becoming thundery here and over Somerset in the late afternoon and evening). An E'ly flow led to a cool day close to E coasts - but except in N England, S Scotland and on Shetland most places had sunny periods during the day. (Hampton Water Works 22.7C, Salsburgh 9.4C maximum, Altnaharra 0.9C minimum, Mumbles Head 15.0 mm, Stornoway 15.9 h.)

by dawn on the 28th mist and fog patches were widespread across the British Isles. There was some rain early in the day over parts of S England and Cent areas of Scotland but falls were light once the thunderstorms in the SW had ended. A few thundery, downpours developed after dawn in the SE but these soon cleared away; during the afternoon and evening more storms developed over W and S Wales and SW England - with thundery rain also in NW Scotland. Sunshine amounts were variable across the British Isles. (Otterbourne Water Works 21.9C, Fair Isle 8.8C maximum, Altnaharra 1.1C minimum, Swyddffynnon 31.2 mm, Kirkwall 14.4 h.)

A NE'ly flow slowly developed on the 29th in most areas. Mist and fog patches were again widespread across the British Isles by dawn. Away from NW Scotland it was a mostly dry day; thundery showers formed here in the afternoon. It was a cool day in N and E areas and a few places close to the North Sea were sunless. It was warm in W areas of the UK and over much of inland Ireland. (Porthmadog 22.2C, Inverbervie 9.5C maximum, Aboyne 0.1C minimum, Altnaharra 15.0 mm, Magilligan 14.0 h.)

A N'ly flow with frontal cloud close to North Sea coastal areas on the 30th led to a cool day here, but with warmer and sunnier conditions further W. Mist and fog patches were again widespread by dawn and the frontal cloud gave some light rain and drizzle in the E. (Porthmadog 22.5C, Loftus 10.0C maximum, Shap 1.1C minimum, Prestwick 2.4 mm, Tiree 15.8 h.)

The frontal cloud in the E pushed further W'wards on the 31st. Overnight there was some rain in East Anglia and Kent - with some heavy thunderstorms during the early hours over Norfolk and Suffolk. During the day advancing rain affected much of E England, reaching SW England and Wales in the evening. Parts of NW Scotland also had some light falls of rain and drizzle later while outbreaks of heavy rain also affected parts of SE England during the day. E England was dull and cool under the cloud and rain. (Glasgow 24.2C, Fylingdales 9.0C maximum, Braemar 2.0C minimum, Wattisham 53.4 mm, Leuchars 16.0 h.)

British Isles weather, June 2016

Central areas of Scotland had an early ground frost in a few places at first on the 1st, then became one of the areas of the UK during the day. E areas of Britain had a rather cloudy day with rain during the night and day in some E areas of England. Cent and S England were also rather cloudy while W areas of the British Isles had long sunny spells - except across NW Scotland. (Derrylin Cornahoule 23.2C, Fylingdales 9.0C maximum, Loch Glascarnoch 2.1C minimum, Stowe 10.2 mm, Tiree 15.9 h.)

There was an early ground frost in parts of S and Cent Scotland on the 2nd; elsewhere it remained cloudy overnight and during the day in E Britain where there was also some light rain at times in places. Cent Scotland and much of inland Ireland had a warm day - as did parts of SW England - but it was cooler in the cloudier E areas, turning cloudier with mist and rain over N Scotland later. Precipitation amounts were generally slight - and it was a sunny day except across the N half of Scotland and E areas of the UK. (Shannon Airport 22.8C, Fylingdales 8.9C maximum, Resallach -0.1C minimum, Baltasound 2.8 mm, Dublin Airport 15.6 h.)

N parts of mainland Scotland and E areas of the UK were again rather cloudy on the 3rd; but the Northern Isles and W parts of the British Isles again had long sunny spells. In the cloudier areas it was again rather cool with rain at times - while there was heavier, thundery rain over parts of Cent Scotland later in the day. (Tyndrum 23.3C, Fylingdales 10.6C maximum, Kielder Castle 1.1C minimum, Fyvie Castle 12.6 mm, Valley 15.5 h.)

A front initially over N Scotland and E parts of the UK moved slowly W'wards on the 4th. There was widespread mist and haze across England and S parts of Ireland and Wales at dawn - with some fog and light drizzle further E in England. During the day some light rain and drizzle continued to affect parts of E England at times; it remained rather cloudy over England and S Wales. Elsewhere, away from NE Scotland, it was a sunny day until the front advanced from the E. Mist and haze again became widespread across England, Wales and E Ireland by midnight. Thundery showers affected west Cheshire and Merseyside in the early evening. (Rostherne 24.0C, Fair Isle 10.3C maximum, Katesbridge 3.1C minimum, Nantwich 1.8 mm, Cork Airport 15.5 h.)

The 5th dawned misty over much of England and parts of Wales and Ireland. This soon cleared and it was then a warm and sunny day across the British Isles, although it was cloudy from S Ireland to the Channel Islands. (Porthmadog 27.8C, Fair Isle 11.2C maximum, Aboyne 2.7C minimum, Newton Rigg 8.2 mm, Lerwick 16.7 h.)

Mist, haze and fog were widespread by dawn on the 6th across much of Ireland, Wales and England as a slack area of high pressure persisted across the British Isles. These soon cleared and warm and sunny day then followed. However, it was cooler along many E coast areas and also rather cloudy in W Ireland and SW parts of England. Thunderstorms affected parts of the west and northwest and mist and fog patches reformed in the evening in S Ireland and SW parts of England and Wales. (Porthmadog 27.6C, Inverbervie 10.4C maximum, Aboyne 2.4C minimum, Newton Rigg 11.4 mm, Lerwick 15.3 h.)

A ridge of high pressure running N-S persisted on the 7th. Ireland, S Wales and SW England had early mist and fog - with fog patches in several other areas of the UK. There was overnight rain in N Ireland and Wales, some of it thundery. During the day further showers and thunderstorms formed quite widely with some torrential downpours and flooding. It was again a cool day close to some North Sea coasts and mist reformed again, widely, in the evening. A house in Mayfield, Midlothian, was struck by lightning and several others flooded during torrential downpours in parts of Scotland. A band of heavy rain also caused travel problems, flooding a number of routes in the Scottish Borders. A 37-year-old man and his five-year-old son were left in a critical condition after they were struck by lightning in Lisburn, County Antrim. (Hull East Park 26.3C, Fair Isle 10.8C maximum, Kinbrace 4.6C minimum, Kenley 48.2 mm, Leconfield 11.7 h.)

After a mild night the 8th was a warm day generally - but with cooler conditions close to the E coast of Britain. E areas of Scotland were rather cloudy while elsewhere sunshine totals varied quite a lot with parts of S England also being rather cloudy. Mist and fog patches were widespread at first across the British Isles; these cleared but showers and thundery downpours again developed in various districts from Cent Scotland to SE and Cent S England. (Pershore 26.3C, Wick Airport 10.7C maximum, Inverbervie 7.7C minimum, Winterbourne No.2 32.6 mm, Cork Airport 14.8 h.)

Mist and fog patches were widespread across Ireland, Wales and some W and cent parts of England by dawn on the 9th. These soon cleared and the warmest conditions then developed in parts of W and NE Ireland and Britain. Showery conditions affected parts of Wales, N England and S and Cent Scotland later in the day. Cloud was fairly extensive except in parts of W Scotland. (Shannon Airport 24.9C, Fair Isle 10.7C maximum, Baltasound 2.7C minimum, Rhyl 9.8 mm, Tiree 14.0 h.)

Weak pressure gradients and a series of weak fronts led to a rather cloud day on the 10th - although it was a little sunnier on the Northern Isles. Mist and fog patches were widespread by dawn - following a night with light falls of rain and drizzle in many places from Cent Scotland S'wards. There was some heavy rain early in the day in parts of E and NE England, with thundery downpours in Cent and N Ireland in the late morning and early afternoon; later parts of Wales and counties close to the north Midlands were also affected. Further thundery outbreaks occurred from the SW Midlands towards the London area during the later afternoon and evening. (St James Park 24.6C, Fair Isle 11.3C maximum, Baltasound 5.2C minimum, Warcop 31.2 mm, Lerwick 7.4 h.)

The 11th was another mostly cloudy day - with the best of the sunshine across the Northern Isles again. Patches of mist or fog again formed widely overnight and many places across the British Isles had outbreaks of rain overnight. These falls continued during the day with some thunderstorms in the afternoon and evening over Northern Ireland and in East Anglia in particular. (Shoreham 23.8C, Inverbervie 9.8C maximum, Kirkwall 4.9C minimum, Wattisham 39.0 mm, Lerwick 11.0 h.)

A sequence of fronts moved slowly NE'wards across many areas on the 12th - with a wave depression forming over East Anglia by midnight. The result of this were widespread falls of rain across the British Isles with some heavy falls in places. There were some heavy, thundery showers over E and N England early on, while a funnel cloud lifted an inflatable slide into the air at the Friskney Show, near Skegness, in the early afternoon. Sunnier conditions followed the rain from the SW later while Shetland had almost unbroken sunshine during the day. Later in the afternoon and into the evening heavy showers and thunderstorms moved from the Midlands towards Essex. (Hereford 22.2C, Inverbervie 11.3C maximum, Baltasound 7.1C minimum, Newton Rigg 40.8 mm, Lerwick 15.7 h.)

Frontal systems and shallow low pressure areas led to further unsettled conditions on the 13th - with rather cloudy skies except over the Northern Isles where sunshine was almost unbroken. Rain and showers affected these cloudy areas with some heavy falls over parts of the Midlands and Cumbria. There were also mist and fog patches in places both early and late in the day - especially in E areas of the UK. (Writtle 20.1C, Morpeth Cockle Park 12.3C maximum, Altnaharra 9.1C minimum, Santon Downham 40.0 mm, Lerwick 16.2 h.)

A shallow area of low pressure remained over cent areas of the UK during the 14th. Visibility was poor both early and late in the day in many E areas of the UK; an exception was NE Scotland with the Northern Isles, and also W Scotland, then having a sunny day. There was a touch of ground frost early in the day in parts of the Highlands - in W Scotland and in many parts of Ireland, Wales and England there were falls of rain overnight. During the day Ireland and N England had some showery falls; further south it was also showery with some heavy, thundery showers over N Wales, the Midlands and East Anglia. (Santon Downham 20.5C, Inverbervie 11.5C maximum, Braemar 2.2C minimum, Market Bosworth 43.0 mm, Lerwick 14.7 h.)

Low pressure remained centred over S parts of the UK on the 15th with a front over N and W areas drawing colder air across Scotland under cloudy skies. E Scotland had extensive rain during the day with heavy falls at times in Aberdeenshire. With one or two localised exceptions the day was generally cloudy with showers in many areas - particularly over Wales and W areas of the UK; it was also a thundery day in many areas. (Cambridge NIAB 21.2C, Aviemore 10.7C maximum, Katesbridge 5.8C minimum, Aboyne 62.0 mm, Valley 14.2 h.)

Overnight into the 16th it was cloudy with rain and drizzle across much of Scotland and N Ireland, but rather misty elsewhere. Across Scotland these conditions continued during the day, leading to a cold and dull day. Parts of coastal NE England had cool and foggy conditions for much of the day; elsewhere the weather consisted of sunshine and showers - with the best of the sunshine around the Thames Estuary. Some of the showers were, again, heavy and thundery - while mist reformed widely in the evening across the E half of England. A lightning strike ignited methane gas at a food waste plant sending a huge fireball into the sky. The Agrivert site at Benson, near Wallingford, Oxfordshire, was struck at about 1620 GMT. Lightning ignited gas stored in a waste digester, causing a fire which burned for 20 minutes and destroyed the roof. A flight from Manchester to Agadir was forced to carry out an unexpected landing at Gatwick after being struck by lightning. (Exeter Airport 21.7C, Loch Glascarnoch 9.4C maximum, Santon Downham 6.6C minimum, Winterbourne No.2 50.4 mm, Shoeburyness 11.7 h.)

A cloudy, N'ly flow affected the British Isles on the 17th. After a misty start across England and Wales many areas in E Scotland and N England had outbreaks of rain at times during the day. Falls were heavier, showery and thundery across the S half of England and Wales during the day, although it turned gradually drier in many W parts of the British Isles as the day developed. (Pershore 21.2C, Dalwhinnie 9.1C maximum, Port Ellen 6.3C minimum, Mumbles Head 28.0 mm, Tiree 12.4 h.)

The N'ly flow gradually retreated E'wards during the 18th - which was another cloudy day over much of England. Rain in E England generally cleared by midday and it then turned sunnier from the W - but an advancing frontal system brought cloud into Ireland in the afternoon, and this then affected most of Ireland by midnight. (Hereford 20.3C, Loftus 11.6C maximum, Tyndrum 2.3C minimum, Northolt 11.4 mm, Tiree 12.5 h.)

A low centred to the W of Scotland drove fronts across most of the British Isles during the 19th. E England and E Scotland had a sunny start to the day, with some mist patches in parts of S England. The overnight rain across Ireland then spread E'wards, giving cloudy skies later across all areas and bringing rain to E parts of England and Scotland by early evening. (Writtle 21.9, Fair Isle 12.1C maximum, Ravensworth 4.2C minimum, Capel Curig 39.0 mm, Shoeburyness 7.7 h.)

The 20th dawned rather cloudy and mild following widespread rainfall overnight. Breaks in the cloud spread SE'wards as the day developed and the rain moved away to the E. However, it was slow to clear the extreme SE of England and there were some heavy, thundery showers, in a line of rainfall that crossed the N Midlands and into East Anglia in the afternoon. (Heathrow 22.7C, Fair Isle 13.4C maximum, Lerwick 10.4C minimum, Brooms Barn 27.2 mm, Morecambe 9.4 h.)

The British Isles was affected by frontal cloud in N and W areas and also in S and SE parts on the 21st - and was consequently rather cloudy, especially in the W. Falls of rain were mostly slight - and very little fell in S districts, falls being more widespread across N Ireland and W Scotland. (Writtle 23.3C, Harris Quidnish 13.3C maximum, Redesdale Camp 5.6C, Harris Quidnish 5.4 mm, Valley 10.2 h.)

Generally cloudy conditions persisted on the 22nd as the two frontal areas remained slow-moving. Rain and drizzle affected the SW England and later the Midlands before dawn, with falls of rain and drizzle also across W Scotland and N parts of Ireland and England. During the day showery outbreaks affected many areas, while thunderstorms moved NE'wards into SE England during the evening. (St Helier 25.1C, Harris Quidnish 14.0C maximum, Kielder Castle 8.3C minimum, Achnagart 17.8 mm, Valley 14.1 h.)

By dawn on the 23rd there had been some severe thunderstorms with torrential rain in SE England and in parts of CS England and East Anglia. A mostly cloudy day followed in the E half of England, with more thundery rain in places here in the afternoon and early evening; the two outbreaks led to serious travel disruption due to flooding and lightning damage. According to Bob Prichard, rainfall totals for the day included 89 mm at Balham, 78 mm at Chessington, 77 mm at Tooting with 65-75 mm over much of the area from Claygate SE London. N Scotland and N and W parts of Ireland were rather cloudy during the day with some rain and showers here. Elsewhere, conditions were largely sunny and warm - after a mild night with minimum temperatures of 15-17C E of a line from Hull to Exeter. Thousands of commuters were stuck at London's Waterloo station as trains were either delayed or cancelled because of flooding, with several people tweeting that they would miss the 10pm deadline to cast their referendum ballot. The Rail Delivery Group, which represents train operating companies and Network Rail, blamed the delays at Waterloo on a flood in the Wimbledon area, adding that torrential rain and lightning damage had caused disruption across the south-east. Services at London Cannon Street, another main station, were closed because of signalling failures. ?Torrential rain and lightning damage have caused disruption to the railway across the south-east of England today with delays and cancellations on many routes into London,? said RDG. (Manston 25.2C, Fair Isle 14.7C maximum, Katesbridge 3.0C minimum, South Farnborough 54.6 mm, Valley 14.0 h.)

The 24th dawned after spells of rain and drizzle across Ireland and Scotland during the early hours. This frontal precipitation moved E'wards during the day with some thunder in a few N and E areas. Falls were heavy in parts of Scotland and E Ireland. On the Northern Isles the visibility remained poor all day - with some thick fog at times. However, away from the Northern Isles most areas saw spells of sunshine - especially places close to the Thames Estuary. (Weybourne 23.2C, Baltasound 13.0C maximum, Hurn 7.2C minimum, Cassley 37.8 mm, Shoeburyness 13.5 h.)

Frontal cloud and rain affected N and W Ireland and Shetland on the 25th with little sunshine here as a result. Elsewhere, precipitation was more showery and there were sunny intervals; these showers were thundery over Cent and E England. These showers were widespread across England and S Scotland - while towards midnight more general frontal rain moved E'wards into W Ireland. Two people were rescued from a car in Kent after it became submerged up to the windows in heavy flooding. A man required medical help having suffered the effects of being in cold water in the car in Kemsing in the evening. Heavy rain caused problems across the county with a brook bursting its banks and flooding 17 homes in Ightham. An elderly couple were also rescued after their car became stuck in flood water in Halstead. Highways England was eventually forced to close the M26 motorway and work through the night to clear floodwater. (Topcliffe 20.9C, Altnahinch Filters 11.6C maximum, Shap 2.3C minimum, Inverbervie 50.6 mm, Jersey Airport 13.1 h.)

Frontal cloud and rain spread from Ireland to all areas on the 26th. Falls were generally light to moderate and much of the UK (except for Northern Ireland and the extreme W of Britain) had some sunshine before the cloud arrived. (Writtle 21.8C, Lerwick 12.8C maximum, Loch Glascarnoch 4.6C minimum, Porthmadog 16.2 mm, Dyce 7.7 h.)

Overnight rain across England cleared the SE by mid-morning on the 27th, to give a W'ly flow to all areas. It turned showery in the W of Scotland later, but most places across the British Isles also had plenty of sunny periods. (Frittenden 23.6C, Cluanie Inn 12.0C maximum, Loch Glascarnoch 8.3C minimum, Cluanie Inn 14.2 mm, Sheffield 11.3 h.)

After a cool start to the day in NE England and E and S Scotland, frontal cloud spread from the W during the 28th across many areas, while a shallow low pushed E'wards across S and Cent England later in the day. After overnight rain in W parts of Scotland and Ireland, all areas had some rainfall during the day as a result. Sunshine amounts were slight away from S England - and there were thundery showers in parts of NE Scotland, N England and SW Wales. Arriva Trains Wales said there were delays of up to 25 minutes on the lines from Whitland to Pembroke Dock, Fishguard Harbour and Carmarthen for a time after lightning damaged signalling equipment. (Gravesend 22.0C, Dalwhinnie 12.3C maximum, Kielder Castle 2.9C minimum, Pembrey Sands 20.0 mm, Yeovilton 7.6 h.)

Low pressure on the 29th (centre 996 mb at 1200 GMT over the Isle of Man) brought frontal rain to much of England, Wales and Ireland during the day. Further N, in lighter winds, precipitation was more showery in nature - but most places remained on the cloudy side. (Shoeburyness 18.9C, Spadeadam 11.4C maximum, Katesbridge 6.6C minimum, Capel Curig 29.6 mm, Kirkwall 5.9 h.)

The 30th was an unsettled day with overnight rain in S England and W Scotland in particular overnight - while W areas of the British Isles had further rainfall during the day. By the evening rainfall was quite widespread across England, after a day with rather cloudy skies in all areas.(Writtle 21.8C, Tulloch Bridge 12.0C maximum, Aboyne 3.4C minimum, Cluanie Inn 23.0 mm, Nottingham 7.2 h.)
