British Isles weather, January 2018

The 1st was a rather showery day in most areas, with some longer spells of rain over S England earlier in the day. Parts of N and E Scotland had a ground frost overnight - with air frost in N Scotland. Some thunder was heard in the W, with showers turning to snow over high ground in Scotland and over parts of the Pennines. It was rather dull over N Ireland and W and N areas of Scotland. (Isles of Scilly 10.8C, Tyndrum 1.7C maximum, Loch Glascarnoch -6.0C minimum, Tyndrum 17.8mm, Charterhall 5.5 h.)

Bands of rain crossed the British Isles on the 2nd and pressure fell as a low centre moved to SW Scotland by 2400 GMT - central pressure 966 mb (storm Eleanor). It was a sunless day in most areas and cold across N and Cent Scotland, after an early air frost here; ground was widespread before dawn across the British Isles. Snow fell in parts of Scotland and winds increased to gale force as the day progressed. Connaught Airport recorded a gust of 97 mph during the day. At least 50,000 ESB customers in the W and NW of Ireland were without power due to Storm Eleanor, the worst-affected counties being Mayo, Galway and Leitrim. In the evening there was extensive disruption around Galway city centre, after high tides caused extensive flooding. A number of cars were swept away by flash floods in Oranmore, Co Galway in the evening. (Isles of Scilly 13.2C, Strathallan 2.1C maximum, Aboyne -4.4C minimum, Capel Curig 39.6 mm, Lerwick 1.9 h.)

Storm Eleanor brought a windy day to all areas on the 3rd, but especially over Ireland, Wales and England. It was cold but largely dry across N and Cent Scotland - although there were some wintry showers. Elsewhere, rain followed by showers crossed the British Isles; there was thunder in places, especially over the Midlands, East Anglia and SW England. During the day some showers merged into longer periods of rain. The Met Office recorded gusts reaching 100 mph overnight and falling trees caused minor injuries to a man in Worcestershire as well as to a man in Wales after one fell on his car. There were numerous road closures and delays on public transport. Over 30,000 homes lost power at some point. Gusts reached 100 mph in Great Dun Fell and 77 mph in High Bradfield. Several major bridges were closed due to high winds and there were numerous reports of fallen trees blocking roads, including the M25. Overturned vehicles led to closures on the A1M, M6 and M5. The Thames Barrier closed at 1015 GMT to protect London from flooding. There were numerous train delays, with National Rail reporting disruption in many parts of the country, including between Worcester and Oxford, between Birmingham and Kings Norton and between Brighton and Haywards Heath in West Sussex. Police on the Isle of Man said a number of roads were closed due to fallen trees, flooding and debris from damaged buildings. The Severn Crossing between Gloucestershire and Monmouthshire and the Orwell Bridge near Ipswich also closed overnight due to the high winds. (Isles of Scilly 11.4C, Altnaharra 0.9C maximum, Altnaharra -5.5C minimum, Eskdalemuir 26.6 mm, Ronaldsway 3.6 h.)

On the 4th another depression crossed Ireland (centred 982 mb over the Isle of Man at 1200 GMT) and N England. The low spread rain NE'wards to the S of it, with windy conditions in S parts of England. To the N of the low it remained mainly dry for most of the time after an early air frost in many places here. It was a cold day to the N of the low - and most places remained rather dull. (Yeovilton 13.2C, Fyvie Castle 0.2C maximum, Altnaharra -6.9C minimum, Plymouth 24.0 mm, Shobdon 2.6 h.)

The 5th was a rather cloudy and showery day as a complex area of low pressure remained slow-moving over the British Isles. Away from S England there was a widespread ground frost over the UK, with a slight air frost in parts of Scotland and N Ireland. Showers fell as snow across Scotland - and in parts of the Midlands early in the day. It was cold in N areas in the N to NE'ly flow there. (Guernsey Airport 10.1C, Dalwhinnie 1.0C maximum, Katesbridge -2.9C minimum, Port Ellen 23.0 mm, Hurn 4.8 h.)

High pressure became established over N areas on the 6th (centre 1031 mb over Cent Scotland by 2400 GMT), leading to a cool NE'ly flow over the S half of the British Isles. There was frost and some showers overnight, with some fog patches by dawn in S England. Further showers occurred during the day - with some wintry falls over areas of Scotland. (St Helier 8.7C, Dalwhinnie -0.2C maximum, South Newington -4.7C minimum, Bainbridge 5.4 mm, Aldergrove 6.3 h.)

Pressure remained generally high on the 7th - above 1032 mb in some areas for a large part of the day. It was a cold, sunny and generally dry day due to the NE'ly wind. Across parts of N and Cent Scotland temperatures remained below freezing and there was some light snowfall in parts of N Scotland. W and N Scotland remained rather cloudy. A few areas close to the North Sea had a light shower or two. (Guernsey Airport 7.3C, Dalwhinnie -2.2C maximum, Dalwhinnie -9.8C minimum, Loftus 2.2 mm, Camborne 7.5 h.)

Ground frost was widespread into the 8th except in a few coastal locations, notably in S parts of England and Ireland. Most areas had an air frost - which was sharp in parts of Scotland and N England. High pressure continued to exert an influence, but a weak front spreading N across S Britain and Ireland later led to a cloudy day in S parts of England, Wales and Ireland. Elsewhere it was a sunny day. Police dealt with 25 road crashes in just one hour as freezing conditions were felt across much of Scotland in the morning. The cold weather also led to disruption on rail services with trains unable to stop at Johnstone in Renfrewshire due to icicles on the overhead lines. Several schools in Scotland were closed to pupils because of heating or water problems. (Isles of Scilly 9.5C, Strathallan -1.4C maximum, Strathallan -9.8C minimum, Stowe 0.4 mm, Aberdaron 6.9 h.)

The 9th was a rather cloudy day except across NW Scotland where the day began with sunny spells. Scotland, N Ireland, N Wales and N England had an air frost in places at first - and there was some fog in parts of England and Wales. Frontal rain spread across Ireland and into Wales and SW England. At Valentia 17 mm fell in the 12 hours ending 1800 GMT. (Isles of Scilly 10.6C, Spadeadam 1.3C maximum, Bridgefoot -4.9C minimum, Camborne 13.0 mm, Aviemore 5.1 h.)

Rain fell across W areas of the British Isles overnight into the 10th, and affected E Britain (mainly England) as it moved NE'wards during the day. Another area of rain affected SW Ireland later in the day (14 mm fell at Sherkin Island in the 12 hours ending 1800 GMT). As the rain moved E early in the day it led to some early fog in places - but most of E Ireland, Wales and S England then had a sunny day. The fog persisted locally, especially over Northern Ireland, and returned to some places in the evening. (Yeovilton 12.1C, Lough Fea 1.8C maximum, Shobdon -1.1C minimum, Cardiff Bute Park 9.2 mm, Yeovilton 7.1 h.)

A mainly mild S'ly flow affected much of the British Isles on the 11th. There was rain at times overnight in W Ireland before dawn (with falls of over 10 mm in the places in the 12 hours ending 0600 GMT). Most inland areas had a ground frost before dawn, with an air frost in places as far S as Hampshire. It was dull, misty and damp over E and SE England; elsewhere there were sunny spells (except in E England and E Scotland) . It remained cold in some areas of high ground (in fog) and in the Scottish glens. (Isles of Scilly 10.1C, Lentran 0.2C maximum, Altnaharra -6.0C minimum, Charsfield 10.2 mm, Camborne 7.0 h.)

There was some fog at first on the 12th with an air frost in E Ireland, Wales and inland areas of Scotland; most inland areas away from E England had a ground frost. Fog was rather persistent in parts of the W Midlands and E Wales. Rain spread into Ireland and W Britain in the evening. Most of Cent and E Britain was dull with a (mainly light) rain or drizzle in places and even in the brighter areas sunshine amounts were small. (Isles of Scilly 10.5C, Llysdinam 2.1Cmaximum, Tain Range -6.9C minimum, Banagher Caugh Hill 3.8 mm, Bala 2.6 h.)

Slow-moving frosts, especially over the W half of the British Isles, led to a mostly cloudy day on the 13th. It was wet in these frontal areas, with heavy falls in places that tended to become light into the evening. Low pressure towards the W of Scotland led to windy conditions in NW Scotland - while high pressure maintained control in E areas. A S#ly flow meant a mainly mild day. (Isles of Scilly 9.8C, Carterhouse 3.4C maximum, Eskdalemuir -0.3C minimum, Camborne 36.2 mm, Kirkwall 0.6 h.)

The 14th was a cloudy day in most areas due (at least in the W) to frontal systems - that brought heavy rain across W and N Scotland and much of Ireland later in the day. A deep low far to the NW led to a windy day in W and N areas with some severe gales later over N Scotland. Areas of Wales, SW England, E Ireland and the extreme SE corner of England had a few sunny spells. (Isles of Scilly 10.9C, Leek 1.8C maximum, Exeter Airport -0.7C minimum, Cluanie Inn 32.0 mm, Bude 5.4 h.)

Fronts crossed all areas on the 15th, introducing a brisk W'ly flow across the British Isles. It was cloudy with rain and strong winds overnight (and no ground frost at low levels), followed by showers weather from the W. It remained rather cloudy and dull in E areas of England with the rain not clearing from here until the afternoon, but Ireland and W areas of England and Wales had some sunny intervals during the day. There was some thunder towards the W during the late afternoon and evening, and mild before a cold front passed. Later the showers turned to snow over high ground in Scotland. (Hurn 12.5C, Dalwhinnie 3.3C maximum, Fylingdales 0.6C minimum, Capel Curig 44.8 mm, Dundrennan 3.6 h.)

Storm Fionn was named on the 16th due to a period of strong winds (not an identifiable low centre) that affected Eire. The strongest gusts there included 137 km/h at Mace Head and 117 km/h at Shannon Airport and Sherkin Island. MSL pressure fell to around 969 ,mb on N Shetland at 1200 GMT in this W'ly flow. After an air frost in E Scotland and widespread overnight showers, the day continued generally showery - but with some sunny spells across England. The showers were mostly of snow or hail (and with local thunder) across Scotland, N England and in N and W Ireland - although snow also fell in Wales and in parts of SW England. Motorists were warned to drive with caution as snow and ice affected large parts of Scotland. Dozens of schools were closed in the Highlands and Dumfries and Galloway, after overnight snowfall. Police reported dealing with jack-knifed lorries on the A9 at Dalwhinnie, and on the M74 between Lockerbie and Moffat. Wintry conditions forced Inverness airport to close for a time. Flights in and out of Aberdeen Airport were also affected and Glasgow Airport was closed for a while as the runway, taxi and passenger routes were cleared. Reported snow depths included 17 cm at Sule Skerry and 28 cm at Drumalbin at 2100 GMT, and 7 cm at Great Dun Fell at 1200 GMT. (Isles of Scilly 9.5C, Dalwhinnie -0.7C maximum, Braemar -2.1C minimum, Sheffield 17.0 mm, Wattisham 6.4 h.)

A W to NW'ly flow dominated the weather for much of the 17th, although by late evening a deepening depression had crossed Ireland it then lay centred, N or Anglesey, at 981 mb at 2400 GMT. There was an air frost across Scotland, N Ireland and N England by dawn, with pockets of frost also as far S as the S Midlands. Hundreds of drivers spent the night in their cars after becoming stranded due to heavy snow. Mountain rescue teams were sent to help those stuck on the M74 in Dumfries and Galloway after severe weather led to closures at Millbank and Beattock. Public transport was disrupted and schools remained closed in parts of Scotland and Northern Ireland. Disruption was also reported on the M62 trans-Pennine motorway, although by Wednesday morning traffic was able to move. Except in W parts of Scotland and Ireland it was a sunny day - with showers (many of them wintry) over Ireland and W Britain overnight, these then spreading across much of Wales and N England during the day. Rain spread quickly NE'wards during the evening, turning to snow away from southern counties. Reported snow depths included 10 cm at Great Dun Fell at 1500 GMT and 39 cm at Eskdalemuir at 1200 GMT. (Isles of Scilly 10.8C, Carterhouse 0.8C maximum, Drumnadrochit -5.0C minimum, Glenanne 20.6 mm, Wattisham 6.5 h.)

The depression crossed N England quickly E'wards during the morning of the 18th. To its N there was a widespread ground frost with overnight snow in Scotland and N England and a sharp air frost in parts of Cent Scotland. The low brought a spell of heavy rain in places, and severe gales caused disruption to much of the UK - with gusts of up to 70 mph. Police in several areas, including Lincolnshire, Norfolk and Gloucestershire, reported fallen trees on or near roads. Damage to overhead electric wires caused problems for train services in the Midlands, and in Scotland, police urged motorists to drive with "extreme caution" in the wintry conditions; drivers in Scotland and N England were being warned not to travel at all until after 0500 GMT, the first such warning issued since high winds in January 2013. Rail commuters faced delays in London, Norfolk, Suffolk, Cambridgeshire, Buckinghamshire, Surrey, Sussex and Hampshire. In Sydenham, south east London, a train hit a tree. Scottish Borders Council said no schools would open today, affecting 15,000 pupils. It was a mild night in S England with overnight minimum temperatures around 8C in places. A blustery day followed in all areas with S England remaining mild but with wintry showers across N Ireland, N England and Scotland. Reported snow depths at 1800 GMT included 15 cm at South Uist Range, 26 cm at West Freugh and 13 cm at Keswick. There was thunder in parts of the southeast in the afternoon and also near a few W and NW coasts. (Swanage 10.5C, Drumnadrochit -0.5C maximum, Loch Glascarnoch -7.7C minimum, Rochdale 20.8 mm, Hurn 5.2 h.)

There was widespread ground frost into the 19th with many inland parts of Britain having a slight air frost. Wintry weather again affected Scotland, N Ireland and N England overnight. Some communities in Scotland remained cut-off and the wintry weather continued during the day in these N areas. Further S it was drier and sunnier. Reported snow depths at 2100 GMT included 13 cm at South Uist Range and 12 cm at Glenanne. Frontal rain spread into SW Ireland later in the day. (Isles of Scilly 8.9C, Dalwhinnie -0.6C maximum, Drumnadrochit -6.8C minimum, Machrihanish 14.8 mm, Lyneham 6.6 h.)

Much of Scotland was very cold on the 20th, with persistent frost in places over a snow cover; many places were sunny, but there were isolated freezing fog patches, and snow showers around northern coasts. It was mostly overcast over Northern Ireland, England and Wales, and except in the S and SW it was also cold. Snow showers also affected N Ireland, N England, N Wales and N parts of the Midlands. Fronts brought rain across much of the S half of England and Wales and it was mild in parts of S wales and SW England. Snow depths at 1200 GMT included 5 cm at Lerwick, 28 cm at Eskdalemuir, 7 cm at Carlisle and 3 cm at Connaught Airport. (Exeter Airport 12.4C, Kinbrace -3.6C maximum, Dalwhinnie -10.4C minimum, Culdrose 19.2 mm, Kinloss 6.4 h.)

Fronts crossed the British Isles from the SW on the 21st, bringing a spell or rain which fell as snow over higher ground and in the colder areas; it was a dull day as a result. There was a widespread frost overnight away from S Britain and S Ireland, and the frost was notably severe in parts of Scotland. The day became very wet everywhere, with rain, preceded by snow which lasted for several hours over much of eastern and northern Britain. There was flooding in Devon and Cornwall. Much milder, drier weather pushed steadily across from the W during the afternoon and evening. By early evening falling snow was largely confined to N Scotland. Motorists in Scotland were urged to exercise caution as the band of snow moved across the country. Earlier drivers in the south-west were urged to "avoid unnecessary journeys" following a spate of road accidents. Police said heavy snowfall across Dumfries and Galloway caused problems on roads including the A75, which was blocked just outside Dumfries for a time. Glasgow Airport was closed for a short time while the runway was cleared of snow. In north Devon, several homes were evacuated after "widespread flooding" sparked by heavy rain; by mid-afternoon the Environment Agency had five flood warnings in place for south-west England and 18 flood alerts while there were 17 flood alerts in Wales. Snow affected driving conditions on the A470 between Betws-y-coed and Blaenau Ffestiniog. In SW England the A399 at Combe Martin was closed following a landslide, while the A361 was also shut near Landkey in Barnstaple. (Exeter Airport 13.3C, Fylingdales -0.1C maximum, Kinbrace -13.7C minimum, Gogerddan 46.4 mm, Lerwick 0.8 h.)

Minimum temperatures across S Ireland, S Wales and S England into the 22nd were around 7-9C while parts of E Scotland had a slight air frost. Temperatures rose to around 12C in the early ours in S England in places before a cold front cleared from the NW. There was overnight rain in SW England (25 mm fell in places) and parts of S England with places elsewhere reporting slight showers during the day. E England was generally the sunniest area while much of W Britain and N Ireland remaining rather dull. (St Helier 11.8C. Carterhouse 4.2C maximum, Aboyne -3.0C minimum, Tyndrum 35.2 mm (possibly melting snow in the gauge), Jersey Airport 4.9 h.)

The 23rd was a mild day with temperatures reaching 10C in E Scotland and 13C in many parts of England. This followed a mild night in S districts - the minimum temperature at Valentia in the 12 hours ending 0600 GMT was 10.3C. There was light rain and drizzle in most areas as fronts passed overhead while heavy rain fell across N Wales, N England and W Scotland in places. The best of the sunshine was to be found across Ireland, following the passage of the rain areas - although the extreme E coast of England and Scotland was also sunny for a time. (Exeter Airport 14.6C, Dalwhinnie 6.5C maximum, Santon Downham 0.1C minimum, Achnagart 37.4 mm (possibly some melting of snow), Morpeth Cockle Park 4.1 h.)

A deepening low, storm Georgina, moved from NW Ireland towards the Northern Isles on the 24th (centre 963 mb at 1200 GMT over Orkney) bringing rain to all areas as its associated fronts moved NE'wards over the British Isles. Much of England remained cloudy but further W there were clearances and sunny spells following the frontal rain. It was mostly rather mild over Scotland and Northern Ireland, and mild or very mild over England and Wales, although it turned rather colder behind the cold front. There were some gusts of around 80 mph in the most exposed W and N areas in the morning and some of the precipitation fell as snow at times across N Scotland. (Santon Downham 14.3C, Aviemore 4.8C maximum, Fyvie Castle 1.3C minimum, Loch Glascarnoch 45.2 mm, Dyce 6.1 h.)

Low pressure was slow-moving over N Ireland and N England on the 25th and the resulting flow from the SW led to a mainly mild day. It was colder in Cent Scotland with some falls of snow here - while the depression brought a spell of frontal rain to Ireland and W Britain - falls in E England were mainly light. There was hail in places in the W, with isolated thunder. Away from W Scotland and N Ireland most places had sunny spells during the day. (Wisley 11.1C, Loch Glascarnoch 1.5C maximum, Fyvie Castle -2.2C minimum, Kinlochewe 21.4 mm, Tibenham Airfield 6.7 h.)

A weak ridge of high pressure on the 26th led to a day with sunny periods after some overnight air frost. Later in the day more general cloud and then rain spread from the W into W Scotland and across Ireland. (Pembrey Sands 10.3C, Baltasound 2.6C maximum, Strathallan -3.5C minimum, Whitechurch 6.2 mm, Morecambe 6.6 h.)

During the 27th a depression moved steadily NE'wards towards Shetland (pressure on N Shetland was about 988 mb at 2400 GMT). After early frost in places, frontal cloud spread rapidly across all areas with rain and drizzle, and a rise in temperature behind a warm front. A following cold front cleared to give showery outbreaks from the W - and the winds increased in speed in N Scotland especially, with gusts of 70-80 mph in the Western and Northern Isles later in the day. (Hawarden and Keswick 13.6C, Lerwick 7.2C maximum, Shoreham -3.1C minimum, Eskdalemuir 24.0 mm, Dyce 2.7 h.)

A shallow frontal wave depression formed to the W and affected much of Scotland on the 28th, giving a wet day here. It was blustery on the S aside of the low (centre 1002 mb N of Peterhead at 2400 GMT) with some light rain and drizzle in places. Under a warm sector it was mainly mild to the S of the low - with some sunny spells in places. (Monks Wood 15.1C, Loch Glascarnoch 6.7C maximum, Balmoral 2.9C minimum, Achnagart 31.8 mm, Wittering 5.6 h.)

A weakening cold front drew rain across the British Isles from the NW during the 29th. Pressure rose behind the front - to pass 1032 mb over much of S England, S wales and S Ireland by late evening) - brining clearer weather with it. After a mild night over England (overnight minimum temperatures of 10-11C in places), showers developed across Scotland, becoming wintry places. It was a blustery day until pressure began to rise. (Heathrow 13.5C, Dalwhinnie 3.0C maximum, Loch Glascarnoch 0.9C minimum, Tyndrum 27.8 mm, Thomastown 6.3 h.)

The 30th saw a widespread air frost before dawn in places as S as SE England, along with some fog patches. Rain affected N Scotland at first. During the day much of Cent and E England was sunny, but frontal rain spread across Ireland and into W Scotland associated with low pressure to the W of Shetland. Another area of rain also affected SW and Cent S England. (Isles of Scilly 11.0C, Pennerley 3.8C maximum, Benson -5.6C minimum, Achnagart 72.0 mm (suspect?), Wellesbourne 6.9 h.)

Outbreaks of rain spread SE'wards during the 31st, with brighter skies following to most districts. The wind turned to a NW'ly direction and there were frequent showers in the N and W. Ahead of the rain it was mild in S England, but temperatures fell behind the (cold front) rainfall. Snow fell over Scotland and N Ireland by dawn, with falls in N England by midday and in the Midlands in the afternoon. There was also some hail and isolated thunder. (Swanage 10.6C, Salsburgh 0.4C maximum, Altnahinch Filters -1.0C minimum, Cassley 21.6 mm, Leeming 6.6 h.)

British Isles weather, February 2018

Low pressure towards the NE led to a cold surface flow from the N/NW on the 1st. Overnight showers fell over Ireland and W Britain with some snow falling over high ground here and in N England. Thunder occurred around the Wirral. Showers continued during the day in N Scotland and in W areas of the British Isles, while more general rain fell over parts of E England during the afternoon and early evening. (Swanage 8.9C, Dalwhinnie 2.8C maximum, Kielder Castle -1.7C minimum, Loch Glascarnoch 21.0 mm, Cork Airport 8.1 h.)

Many inland areas had a ground frost into the 2nd and showers, some of them wintry, affected N Scotland overnight. During the day it was generally cloudy with showers close to both W and E coasts. Later in the day frontal rain spread E'wards across Ireland and into some W parts of Britain. Pressure rose slightly during the day, reducing the strong winds in the E. (Cardiff Bute Park 9.7C, Dalwhinnie 3.5C maximum, Salsburgh -0.8C minimum, Bridlington 8.2 mm, Morecambe 7.2 h.)

Away from Ireland there was widespread ground frost into the 3rd before an area of rain spread from the W. Areas of E Scotland and E England also recorded an air frost ahead of the rain. It was a wet day in most areas, with some snow in the N and E - especially over higher ground - as the rain met colder air. It was a dull day in the E, but it brightened up across Ireland and W Scotland as the rain cleared. (St Helier 8.9C, Balmoral 0.9C maximum, Topcliffe -3.9C minimum, Capel Curig 15.8 mm, Shannon Airport 6.7 h.)

Away from S parts of Ireland and England a ground frost was widespread on the 4th, with an air frost in a few areas. E and SE areas of England, in particular, had some showers during the day - as did E Ireland. The best of the sunshine tended to occur in Ireland and W areas of Britain. A SE'ly flow led to a cold day in S areas - but it was milder in the N under a flow from the SW. (Belmullet 10.5C, Balmoral 2.1C maximum, Castlederg -2.1c minimum, Balmoral 6.4 mm, Tiree 7.8 h.)

Away from S Ireland and some coastal areas there was a widespread air frost on the 5th. It was cloudy in many areas during the day and, after a misty start in parts of Ireland, showers affected some areas, notably Cent and E England. There was lying snow over parts of east Kent in the morning. Police warned drivers to take extra care after wintry conditions led to a series of accidents on the M20 motorway in Kent. Later in the day more cloud and some rain spread across Ireland and into W Scotland, with the rain falling as snow on the leading edge in many areas. (Stornoway 7.3C, Spadeadam 0.2C maximum, Katesbridge -6.0c minimum, Tiree 5.8 mm, Wellesbourne 7.7 h.)

Away from W Ireland and the Northern Isles a ground frost was widespread on the 6th with many inland areas having an air frost. There was overnight snow in parts of Ireland and Scotland - and many other areas had spells of sleet or snow during the day. It was a cold day - especially from N England through Wales and the W Midlands to SW England, where it was also a dull day. (Cork Airport 5.8C, Okehampton -0.9C maximum, South Newington -4.6C minimum, Camborne 10.4 mm, Cork Airport 8.5 h.)

Air frost was widespread into the 7th away from W and SW Ireland and SW England and the Channel Islands. There was some overnight snow in parts of E and SE England which slowly cleared away to the E. Frontal rain, turning later to snow as it moved E'wards, affected Ireland in the late morning and Scotland in the afternoon. Away from W Ireland it was a generally cold and cloudy day; ahead of the rain it was sunny across England and SE Scotland. (Belmullet and Valentia 8.5C, Spadeadam -1.0C maximum, Tulloch Bridge -10.1C minimum, Achnagart 10.6 mm, Odiham 7.7 h.)

Fronts were slow-moving from the W during the 8th. Cloud and rain affected Ireland, Scotland and W Britain o overnight - further E there was a widespread air frost. The rain affected Wales, W Britain, Scotland and Ireland during the day and, away from SE England and NE Scotland, it was a mainly dull day. Further outbreaks of rain moved into western and N Scotland and Northern Ireland during the late afternoon and evening. (Hawarden 10.5C, Dalwhinnie 3.8C maximum, Shoreham -6.4C minimum, Capel Curig 46.0 mm, Shoeburyness 6.8 h.)

Frontal rain crossed Britain during the morning of the 9th, with parts of Ireland and W Scotland having an air frost in the clearer air. As the rain cleared away towards the E most of the British Isles had spells of sunshine - an exception was the extreme E of East Anglia and Kent where it remained dull. After a spell of showery conditions, further frontal rain moved into Ireland and W Scotland in the afternoon and evening. (St Helier 7.8C, Dalwhinnie 1.7C maximum, Killylane -2.9C minimum, Usk No.2 12.4 mm, St Athan 8.3 h.)

Fronts pushed E'wards across all areas on the 10th, with a wave depression rapidly crossing the British Isles towards NE England (centred 983 mb at2400 GMT). Ireland, W and N Scotland were frost-free overnight with outbreaks of rain. The rain was followed by showers, but there was little sunshine away from Ireland and N areas of Scotland. Heavy rain spread across many central and northern districts during the afternoon with snow falling across parts of Scotland, N England and N Ireland in the evening. (Hawarden 12.4C, Dalwhinnie 4.8C maximum, Benson -6.5C minimum, Capel Curig 45.2 mm, Kinloss 3.9 h.)

Overnight rain fell as sleet and snow in parts of Scotland, N Ireland and N England into the 11th. As the rain and snow cleared it was followed by showers and sunny intervals from the W. These fell as snow and hail in places - with snow as far S as Cornwall. There was also some isolated thunder heard in NW England. There was an air frost in parts of the N half of the British Isles and a cold day followed everywhere. (Shoreham 8.4C, Banagher Caugh Hill 0.4C maximum, Loch Glascarnoch -4.5C minimum, West Freugh 14.4 mm, Charterhall 7.8 h.)

Air frost was widespread inland on the 12th in a NW'ly flow under a weak ridge of high pressure. Overnight showers fell in the W half of the British Isles - wintry in many parts of Scotland and N Ireland. These continued during the day - falling as rain in the S - although most areas also had long sells of sunshine. Rain moved into Ireland in the evening and also extended E'wards across S England. By 2400 GMT a shallow wave depression (centre 991 mb) was located over S Ireland. (Hurn 8.7C, Carterhouse 1.0C maximum, Drumnadrochit -7.1C minimum, Ballypatrick Forest 8.2 mm, Manston 8.5 h.)

England and E Scotland had a widespread ground frost into the 13th, ahead of rain (with snow in places away from the S) that moved E'wards across all areas overnight and into the day. Rain was still falling in East Anglia in the late evening, but away from E areas (and especially across Ireland) the rain was followed by sunny periods and a scattering of showers. These showers were wintry over N Scotland. (St Helier 8.7C, Dalwhinnie 0.8C maximum, Loch Glascarnoch -1.1C minimum, Achnagart 27.0 mm, Cork Airport 8.8 h.)

There was a widespread air frost over the UK into the 14th - with a ground across much of Ireland - ahead of rain that spread across Ireland by dawn. Parts of E England had some mist and fog patches around dawn. This rain then spread to all areas during the day, with some snow in N and Cent areas. It was a mainly cloudy day, but some sunshine occurred in parts of W Scotland and N and Cent Ireland as milder air moved NE'wards across S areas. Showers behind the main rain areas contained some thunder in the NW in the evening. (Bude 11.5C, Dalwhinnie 2.3C maximum, Topcliffe -7.6C minimum, Shap 21.6 mm, Thomastown 3.3 h.)

A deep low initially to the NW of Scotland early on the 15th led to a blustery day with showers and sunshine. These showers fell as hail and snow in places. It was a cold day across Scotland and N Ireland although, away from W Scotland, most areas had a sunny day. It was mild in SE areas of England. (Langdon Bay 11.0C, Dalwhinnie 1.9C maximum, Killylane -0.2C minimum, Achnagart 39.4 mm, Hawarden 8.3 h.)

Air and ground frosts were fairly widespread on the 16th with rain and some snow overnight across many parts of Ireland and Scotland. E Scotland and most areas of England and Wales had sunny spells for much of the day, although it clouded over from the west, with rain moving into Ireland, and into N and W areas of Britain by late evening. It wasa quite a mild day in S areas. (Plymouth 11.2C, Dalwhinnie 3.3C maximum, South Newington -4.3C minimum, Harris Quidnish 18.6 mm, Tibenham Airfield 8.8 h.)

E areas of England began the 17th with an air frost - with some mist patches - ahead of frontal rain in W areas that moved further E'wards, weakening as it did so, during the day. The rain tended to die out over the E Midlands and East Anglia in the early afternoon. Showery conditions affected W areas during the day, but most areas saw brighter weather during the day. It was mostly quite mild, especially over England and Wales. In the evening a further area of rain reached S wares of England and Ireland from the W. (Hereford 11.9C, Dalwhinnie 3.5C maximum, Odiham -3.1C minimum, Cluanie Inn 17.8 mm, Aberdaron 9.1 h.)

The day was dull in most areas, although there was some sunshine ahead of the rain in NE Scotland, E and SE England. Some coasts and hills were foggy at during the day. The day turned mild as the rain arrived. (North Wyke 12.8C, Dalwhinnie 3.5C maximum, Aboyne -4.6C minimum, Port Ellen 10.4 mm, Manston 7.7 h.)

Slow-moving fronts led to a mainly dull day on the 19th. The cloud led to a relatively mild night in most areas - Ireland was misty overnight and as early rain moved E'wards patches of mist and fog formed in W Britain. A rather misty day followed in all areas and temperatures in many areas reach 10C. The best of any sunshine was to be found in Ireland with most of the UK having a dull day. (Cardiff Bute Park 14.2C, Inverbervie 6.0C maximum, Baltasound 1.0C minimum, Harris Quidnish 10.0 mm, Cork Airport 4.2 h.)

There was some rain overnight into the 20th in E Britain as high pressure began to build in the W - centred at 1032 mb over Cent Scotland by 2400 GMT. Many districts were quite sunny, but there were some showers in the NW, and much of E and SE England was quite cloudy with patchy rain. Away from the rain most areas were mild during the day - with areas around the Irish Sea being quite sunny. (Strathallan 12.0C, Cromer 5.6C maximum, Katesbridge -0.9C minimum, Lerwick 8.8 mm, Dundrennan 8.9 h.)

The 21st dawned mist in E England, across many parts of Ireland, and in a few other areas - under high pressure that led to a widespread ground frost. Air frost was widespread over Ireland and Scotland. The day was largely dry, apart from some patchy rain in parts of E England as the high pressure moved NE'wards. Ireland, S England and much of Scotland had a sunny day, with rather cloudy conditions over Cent England and East Anglia. It was mild in places in the sunnier areas. (Bridgefoot 10.5C, High Wycombe 4.4C maximum, Tulloch Bridge -6.0C minimum, Scarborough 2.8 mm, Charterhall 8.9 h.)

The British Isles lay under a slight ridge from an area of high pressure over Scandinavia on the 22nd. There were a few patches of rain at first, mainly in E and Cent areas and in parts of Ireland. Away from Ireland there was air frost in places and a widespread ground frost - with some mist in many E and S areas of England. Most places remained dry during the day - although it was generally rather cloudy away from parts of E and S England. (Valentia 9.1C, Leek 1.6C maximum, Shap -5.4C minimum, Machrihanish 4.2 mm, Bude 9.3 h.)

There was a widespread air frost over England, Wales and E Scotland into the 23rd along with widespread mist and haze in many areas by dawn. The day was mainly dry, although there were a few showers over Ireland and W Scotland. Elsewhere, there were long sunny spells in places. (Kinlochewe 8.1C, Okehampton 1.3C maximum, South Newington -7.1C minimum, Frittenden 0.2 mm, Yeovilton 9.4 h.)

The 24th was mostly sunny, dry and cold with some places in England having one of their sunniest February days on record (in excess of 9 h of bright sunshine). Air frost was widespread over England, Wales and Scotland, while during the day parts of Ireland remained rather misty. Ireland, W and N Scotland were rather cloudy and cold. (Pembrey Sands 8.9C, Killylane 1.4C maximum, Wiggonholt -5.5C minimum, Lerwick 0.2 mm, Valley 9.7 h.)

High pressure over Scandinavia brought a brisk flow from the E across S parts of the UK on the 25th. After a widespread air frost (with some early mist over Ireland) the day was generally dry, cold and sunny. Light wintry showers began to affect eastern coastal districts during the evening. The day was, again, one of the sunniest in February on record at many locations - although parts of E and NE Scotland were rather dull. (Mona 9.4C, Lake Vyrnwy 1.6C maximum, Loch Glascarnoch -8.4C minimum, Baltasound 2.4 mm, Aberdaron, Valley 10.1 h.)

Except in some northwestern areas, it was very cold on the 26th. Air frost was widespread away from W Ireland and W Scotland. There was some sunshine, especially in the north and southwest, but also a lot of snow showers, especially over England. However, the water content of the snow was very low, with little water equivalent in raingauges, and generally a fairly rapid evaporation/sublimation of temporary snow cover. With further snow forecast, rail firms warned of disruption, with Southeastern advising passengers to complete journeys by 1800 GMT. A snow emergency was declared in Kent this afternoon. (Valentia 7.3C, Lake Vyrnwy -1.3C maximum, Aviemore -6.0C minimum, Dyce 1.8 mm, Lerwick 9.3 h.)

High pressure on the 27th continued to draw very cold air into the UK. After a widespread air frost (only a few coastal locations in W coastal areas of the UK and Ireland escaped this) it was a very cold day, exceptionally cold in much of the SE. There was some sunshine, but widespread snow showers. Longer spells of snow affected the extreme SE overnight, and also moved W'wards across much of Scotland, N England, the NW Midlands and N and W Wales overnight, with further prolonged outbreaks over much of E Scotland and NE England during the day. There was isolated thunder near the E coast. Hundreds of trains were cancelled, many schools closed with Kent, Surrey, Suffolk and Sussex among the worst-hit counties, seeing 5-10 cm of snow, while NE England received up to 8 cm as of 1000 GMT. Overnight, rail operators ran empty trains to keep tracks clear of snow, but hundreds of services were cancelled. The A19 in North Yorkshire was closed after a snow-related crash, and some lanes on motorways were blocked due to the snow. (Belmullet 7.5C. Wych Cross -2.5C maximum, South Farnborough -8.9C minimum, Morpeth Cockle Park 8.4 mm, Camborne 8.5 h.)

The 28th was exceptionally cold, with persistent frost in all except a few S and W districts and a fresh E'ly wind, bringing widespread snow showers. These were particularly heavy, and essentially persistent, off the long sea track into NE England and E Scotland; there was some thunder too, notably in the Newcastle area. Widespread disruption resulted. Away from the shower tracks it was quite sunny, chiefly in the S and W. Commuters were warned of major disruption on the road and rail networks after a second day of severe weather across the UK. There were major travel problems in Glasgow as well as many other places around the UK. The worst affected areas in England were Kent, East Anglia and NE England. Flights to and from Glasgow were cancelled while more than 100 flights at Heathrow were dropped and services at London City were also suspended. Schools in Wales were set to close until next week while more than 2,624 schools in England and 1,600 in Scotland were shut. Rural communities were warned they could be cut off by power outages and mobile phone signal failures. Most flights out of Edinburgh were cancelled. Train services impacted include c2c, Caledonian Sleeper, CrossCountry, East Midlands Trains, Grand Central, Greater Anglia, Hull Trains, London Overground, Merseyrail, Northern, ScotRail, South Western Railway, Southeastern, Stansted Express, TfL Rail, TransPennine Express, Virgin Trains and Virgin Trains East Coast. Major problems and closures on main roads across the country including various parts of the A1, and the A66 across the Pennines.

A boy in Basildon, Essex, was saved by firefighters after he got trapped in the middle of a frozen lake when the ice broke up. Police in Macclesfield said they arrested two suspected thieves after tracking their footprints through the snow. Hospitals in Glasgow, Grimsby, Scunthorpe and Goole cancelled all outpatient appointments while Harrogate hospital asked staff who can walk to work to go in to cover shifts. Chatham Ski and Snowboard Centre in Gillingham, Kent, was forced to close because of the heavy snow. (Belmullet 3.8C, Braemar -5.3C maximum, South Farnborough -11.7C minimum, Ravensworth 6.8 mm, Guernsey Airport 9.3 h.)

British Isles weather, March 2018

High pressure over Scandinavia continued to bring a cold E'ly flow across the British Isles on the 1st. Air frost was widespread and only in a few coastal areas did the air temperature rise above 0C during the day. Showers and longer spells of snowfall were widespread across the British Isles. England and Wales had a rather dull day but there were long spells of sunshine in parts of N and W Scotland, with sunny intervals across W Ireland and in many other areas of Scotland. Even the Isles of Scilly had heavy snow in the evening and in many places it was the coldest March day in over a century according to the daytime maximum temperatures. UK roads, railways and airports were severely affected by snow for a third day, with thousands of schools shut. A seven-year-old girl died after a car crashed into a house in Looe, Cornwall, while a 75-year-old woman has been found dead in a snowy street in Leeds. National Grid warned that there may not be enough gas to meet demand in the UK, leading to possible shortages for industrial users. More than 300 people were stranded on a motorway in Scotland in freezing temperatures overnight into today - some for 20 hours. The M66 between Ramsbottom and Bury was closed due to a 16-vehicle crash. In Lincolnshire, drivers were stuck overnight on the A52 between Boston and Skegness. Lincolnshire Police said all major routes in the county were blocked either by snow, HGVs or cars. Across the UK, more than 20 rail operators were running a reduced service. In London, Paddington Station was closed for nearly three hours due to severe weather conditions. National Rail was reporting mass disruption in the Scotland, NE England, SE England and SW England. Arriva Trains Wales was running amended timetables throughout Wales and all trains from Cardiff to Manchester were disrupted. Airports across Britain were being affected by the cold weather, and the knock-on effect of other terminals across the UK and Europe cancelling flights. At Glasgow Airport more than 200 passengers spent the night in the terminal. (Malin Head 2.8C, Tredegar Bryn Bach Park -5.2C maximum, Kinloss -10.3C minimum, Fyvie Castle 3.2 mm, Loch Glascarnoch 6.4 h.)

The 2nd was another cold day across the British Isles, although across much of Ireland, W Scotland, SW England and the Channel Islands the temperature did rise above 0C during the day. Parts of E England also rose above 0C despite it being a dull day almost everywhere. The E'ly winds were accompanied by gusts of 60-70 mph in some of the more exposed parts of England and Wales, although the wind did ease slowly during the day. There were further frequent snow showers over E and N Scotland, and outbreaks of snow moved north across much of England and Wales as fronts moved N'wards here. Parts of SW England had gale-driven heavy snow and parts of S England reported freezing rain for a time. The fronts bright less cold air and rain into southernmost Britain, chiefly Scilly and the Channel Islands - while the snowfall across Scotland and Ireland tended to diminish as the day progressed. Reported snow depths included Casement Aerodrome 19 cm, Carlisle 16 cm, Dublin Airport 14 cm, Emley Moor 14 cm, Lossiemouth 10 cm and Odiham 10 cm. Flights and trains were cancelled and thousands of schools were shut. Rail networks including Southeastern, South Western and ScotRail advised people not to travel on their routes. More than 13,000 customers were without power in SW England, S Wales and the Midlands. Major incidents were declared in Wiltshire, Hampshire and Avon and Somerset, as blizzards brought roads to a standstill. The M62 near Manchester was closed "indefinitely" while the military helped police free stranded motorists. Officers were loaned poles to search for vehicles buried on the A386 in Devon. The Environment Agency issued 15 flood warnings and 36 flood alerts for coastal areas in the SW England and NE England. Severe flooding was reported in Penzance, Cornwall, due to high river levels and swollen seas caused by storm Emma. There was a warning of black ice on the M6, while some of the worst problems were near Rochdale on the M62 and on the A303 near Ilminster and the A31 in the New Forest. Much of Wales was brought to a standstill, where routine operations were cancelled as health boards made a plea for staff to attend work. Travel conditions in Scotland remained treacherous. Passengers who boarded a South Western Railway train to Weymouth at 1705 GMT on Thursday were still in their carriages on Friday morning after their train broke down in the middle of the night. Across the UK, more than 20 rail operators were running a reduced service. Most airports cancelled flights and suffered delays. (St Helier 6.7C, Tredegar Bryn Bach Park -3.9C maximum, Baltasound -6.7C minimum, Isles of Scilly 33.8 mm, Kirkwall 1.8 h.)

Away from parts of W Scotland and N Ireland - and on Scilly and the Channel Islands where minimum temperatures overnight were 3-4C - the 3rd began with another widespread air frost. Temperatures then rose above 0C in most areas away from high ground. Most places were dull with mist and fog in many areas as milder air from the S met the cold, melting snow-covered surface and the snow thawed. There were further outbreaks of snow in many N areas following overnight falls in E England and parts of Ireland. By midnight falling snow was largely confined to NE Scotland with reports of light rain in many other parts of the British Isles. Snow depths this morning included St Athan 55 cm, Drumalbin 46 cm, Glasgow 40 cm, Spadeadam 36 cm, Wittering 33 cm and Hereford 27 cm. Hundreds of people remained without power, and motorists and rail passengers were told to expect continued disruption on roads and railways. The Environment Agency had 13 flood warnings in operation by midday, mainly in the south-west and north-east England. There was a warning of for much of SE England, the Midlands, Wales and Northern Ireland. In Scotland, government ministers asked for volunteers to help in clearing up local roads and pavements, and checking on vulnerable people. In Dawlish, Devon, the coastal rail line reopened after being closed on Saturday morning, due to flooding caused by high tides. The M62 in Greater Manchester reopened in the early hours of Saturday, having been shut for more than a day due to severe weather conditions. A number of football games in the Championship and the Scottish Premiership have been postponed. Across the UK, more than 20 rail operators were running a reduced service with Virgin Trains not running any services north of Newcastle on Saturday, with their route between Carlisle and Scotland closed with no replacement buses running. Arriva Trains Wales said a limited service was running and passengers have been advised only to travel if essential up until Monday morning. Glasgow Airport was open after "the worst snowfall in its history" but still warned of delays and cancellations. Other airports also reopened but with much-reduced capacity. (St Helier 9.7C, Carterhouse -1.9C maximum, Pennerley -4.5C minimum, Okehampton 31.4 mm, Morecambe 3.8 h.)

Cent areas of England and Scotland had an air frost on the 4th while a shallow area of low pressure remained slow-moving close to SE Ireland throughout the day. Away from Shetland and the S half of England and Wales it was a cloudy day. Scotland remained cold with some snowfalls, and some snow also fell in N England for a while. S Britain was milder with showers, and a longer spell of rain E of London. There was widespread mist, and some patches of fog, in many areas of Ireland, Wales and in N ad Cent England as warmer air met thawing snow. Icy roads continued to cause disruption in parts of the UK. Many rail services continued to be affected by lying snow and ice. Meanwhile, many rural communities in south-west England which had been cut off by poor conditions could now be reached. People in parts of London and SE England were being urged to only use water when it is "essential" after supplies were hit following the severe weather. On Sunday evening Devon County Council said the roads to cut-off communities such as Lynmouth and Lynton were now clear. (Chivenor 11.7C, Balmoral 0.1C maximum, Newton Rigg -2.4C minimum, Boscombe Down 62.6 mm, Hurn 6.0 h.)

Low pressure remained centred over the British Isles on the 5th leading to outbreaks of rain that moved N'wards over many areas during the day. Away from the rain it remained misty in many areas. Few places had an overnight air frost and temperatures rose during the day to above 10C in parts of S and E England. Extensive snow cover remained in parts of Wales and Cumbria, and over high ground in Scotland and many of these areas had fog patches during the day. Much of W and N England, Ireland, Wales and Scotland had a dull day with some persistent rain in places. (Weybourne 11.9C, Balmoral 1.0C maximum, Shap -3.1C minimum, Whitechurch 28.6 mm, Waddington 4.6 h.)

Pressure remained low on the 6th. Rain moved slowly N'wards across many areas overnight and during the day, with further snowfall in N and Cent Scotland. Drier weather, with brighter intervals, followed from the S - although it remained sunless in much of N Ireland, N England and Scotland. More rain moved into the Channel Islands during the afternoon and into parts of S England in the evening. It was again cold across the N half of Scotland, but mild in S England. Persistent rain and melting snow caused flooding across Scotland, and the Scottish Environment Protection Agency issued multiple alerts for E, S and west central Scotland. Police warned of severe flooding on the A92 between Dundee and Montrose. In the NE Scotland, ScotRail said flooding between Dyce and Inverurie had closed the line and meant services could not operate between Aberdeen and Inverness.

(St. James Park 11.7C, Dalwhinnie 3.4C maximum, Dalwhinnie -3.3C minimum, Aboyne 21.2 mm, Aberdaron 9.9 h.)

There was a widespread air frost into the 8th across Scotland, Ireland and N England as rain moved across England and Wales overnight; this rain fell as snow in parts of N Wales and N England. The rain gradually cleared from Cent and E areas of England and many places then had some showers and sunny spells during the day. More than 120 schools were closed and there were hazardous driving conditions after heavy snowfall early in the day over N Wales. The A470 in Conwy county was closed for a time while snow also affected the A487 in Gwynedd and the A55 from Bangor to Halkyn, Flintshire. Commuters faced delays in the morning rush hour after overnight snow brought disruption to parts of Yorkshire. Bus services were affected with some operators, including Arriva Yorkshire, suspending services in parts of the county.

Rain over England, Wales and Ireland made little progress N'wards into Scotland and N Scotland remained dry with some sunshine throughout the day. Elsewhere it was a rather dull day - SW England and few places in Cent Ireland being exceptions - with rain at times that fell as snow over higher ground in N England. The weather gradually cleared up from the SW with widespread mist and fog patches in the evening from S Scotland southwards. (Kew Gardens 15.3C, Braemar 1.8C maximum, Kinbrace -8.6C minimum, Capel Curig 29.8 mm, Camborne 6.3 h.)

The 11th dawned with widespread mist and fog from cent Scotland S'wards; further north rain moved N'wards overnight and large cleared N Scotland by midday. An area of low pressure moving N'wards (centred at 980 mb close to Jersey by 2400 GMT) spread further rain N'wards across Ireland, Wales ad England during the day - with some thundery conditions in parts of Cent S and SE England in the evening. Many areas had a rather cloudy day although it was quite warm in S England. (Wiggonholt 15.3C, Lerwick 3.4C maximum, Shobdon -0.5C minimum, Harris Quidnish 17.6 mm, Tiree 6.4 h.)

During the 17th unseasonably cold air spread SW'wards overnight, preceded by rain in parts of the south and southwest. The day brought blustery winds, widespread snow showers, with longer spells of mostly light snow in the south. There were brighter spells in the west and north, and NW Scotland was dry, quite sunny and rather less cold than elsewhere; in many other districts temperatures were below freezing all day. The heaviest snow showers affected NE England into the North Midlands, as well as parts of S England - including Hampshire, Sussex and Kent. Snow and ice has gripped parts of the UK as a result of the cold air; more than 100 flights to and from Heathrow Airport were cancelled and drivers were warned to take care. National Rail has advised passengers to check for service disruptions before travelling. The snow spread as far W as E Ireland. In North Yorkshire mountain rescue teams rescued 30 runners who were treated with hypothermia while undertaking a 55-mile ultramarathon in blizzard conditions.

There was a widespread air frost into the 18th - notably severe for the season under clear skies in the southwest, before snow arrived here, having spread westwards across England and Wales. Another unseasonably cold day, with penetrating winds, followed over most of England, Wales, Ireland and S Scotland; temperatures were below freezing throughout the 24 hours in many part of England and Wales - a very rare event for mid-March on such a widespread scale. The Channel Islands and Scilly, and some of the more N'ly areas, were rather less cold with some rain; elsewhere there were further outbreaks of snow. It was foggy at times in the snow. As the day developed the snowfall gradually eased in E areas og the UK. At least one hospital in Devon was asking for volunteer drivers to help ferry staff to and from its facilities. Some airports were shut for a while and several sporting events have been cancelled, including the Reading half-marathon, as some roads were impassable. Bristol Airport was closed temporarily due to the snowfall. Overnight on Saturday, officers from Lincolnshire Police spent seven hours digging out 35 stranded vehicles after they became stuck in snow drifts on the A158 near Edlington. There were delays on the Severn Bridge as high winds caused the closure of a lane. South Western Railway warned freezing temperatures were causing numerous points failures, including at Eastleigh and Aldershot. Cheshire Police warned there was "no route to safely cross the Pennines into Cheshire". In Cumbria, mountain rescue teams were called to help 15 people stuck in a cafe near Kirkby Stephen, and an ambulance that could not reach patients in Langdale. The City of Lincoln 10km and Shrewsbury 10km run were called off, as were half-marathons in Wigan and Wilmslow. Ice resulted in delays and 37 cancellations at Gatwick Airport on Sunday night.

There was a widespread air frost on the 19th with a severe frost under the clearer skies and lighter winds in Scotland. The exceptionally cold air and penetrating easterly wind extended southwards to the Channel Islands and Scilly, and persisted over the S and SW of England during the day under cloudy skies; there was some further snow overnight, as well as during the day over the southwest peninsula and the Channel Islands. Many other districts were sunny, with the sunny conditions gradually edging S'wards; there was a steady thaw of lying snow as a result in most places. However, another area of cloud and a few light showers moved S'wards over E Scotland and NE England later, as a N'ly flow became established over much of the UK. Much of the UK awoke to severe weather warnings of ice. A 64-mile stretch of the A30 in Devon was closed but reopened on Monday morning. Overnight dozens of vehicles stranded were on the A30 in Devon and hundreds of schools were closed in SW England and Wales the snow continued to cause disruption. A 64-mile stretch of the A30 from the M5 at Exeter to near Bodmin in Cornwall was closed by Devon and Cornwall Police to allow its officers and Highways England to clear the route. The runway at Exeter Airport closed for a while but later re-opened. (Achnagart 9.5C, Okehampton -0.5C maximum, Altnaharra -10.3C minimum, Dunkeswell 6.4 mm, Tiree 11.8 h.)

High pressure to the SW of the British Isles on the 20th resulted in a widespread air frost overnight; however, it was marginally milder overnight in parts of Cent and E England as some frontal cloud, rain and sleet moved SE'wards here. This area of cloud and some light rain then pivoted to lie from E Wales to North Yorkshire in the afternoon; most of the rain was at its eastern end. It was a sunny day across Ireland, S Scotland, W Wales and SW England - with sunny periods elsewhere at times. It turned cloudy over NW Scotland and N Ireland later in the day. It was a cold day in many areas - an exception being some of the sunnier parts of Scotland and Ireland. It was locally very cold in some of the cloudier locations and over the remaining snow cover, particularly in Devon. (Killowen 11.0C, Okehampton 4.5C maximum, Tulloch Bridge -9.5C minimum, Okehampton 4.0 mm, Aberdaron 11.6 h.)

Away from W areas of Scotland and Ireland, the Northern Isles and parts of SW England, the 21st had a widespread air frost before dawn. Cloud and rain spread SE'wards across Scotland and into N parts of Ireland, Wales and England later. Elsewhere it was a mainly sunny day, especially in SE England and East Anglia. It was mildest across Ireland and in N and E Scotland, along with the sunnier SE of England - and rather cool elsewhere. (Derrylin Cornahoule 13.3C, Okehampton 4.7C maximum, Topcliffe -6.1C minimum, Cluanie Inn 28.6 mm, Wattisham 10.1 h.)

A rather cloudy night into the 22nd meant only a slight ground frost in a few places. Overnight rain cleared E England in the morning and most E areas then had a day with sunny periods. Approaching low pressure in the W (centre 992 mb over SW Ireland by 2400 GMT) brought cloud and then rain from the W leading to a dull day in W and Cent areas of the British Isles. 15 mm of rain fell in the period 0600-1800 GMT at Valentia. It was a mild day in the sunny areas in the E, cooler elsewhere. (Fyvie Castle 15.1C, Liscombe 5.5C maximum, Exeter Airport -2.2C minimum, Killowen 7.0 mm, Dyce 6.7 h.)

Cloud and rain spread across all areas overnight into the 23rd and then cleared from N Scotland during the day. Showers and sunny intervals followed during the day. In the afternoon further rain, heaviest in SW England and S Wales, moved N'wards towards Cent Ireland and N England by the evening as a deep depression moved E'wards into Biscay. (Gravesend 14.4C, Resallach 5.4C maximum, Lough Fea 3.0C minimum, Resallach 28.6 mm, Boulmer 7.3 h.)

There was an air frost into the 24th in inland areas of Scotland and in parts of E and N Ireland. Elsewhere rain and drizzle was widespread overnight leading to some misty conditions. Scotland and Ireland had sunny spells and some showers during the day. Elsewhere was mostly dull and misty, with hill fog and patchy drizzle; there were some spells of rain from SW England to the Wash that then slowly moved away towards the SE - much of Cent, SE and S England remained misty into the evening. Away from the sunshine it was rather cold. (Killowen 13.9C, Okehampton 5.7C maximum, Castlederg -3.7C minimum, Culdrose 15.8 mm, Tiree 11.5 h.)

Away from the misty S, Cent and E areas of England there was a widespread ground frost into the 25th - with an air frost in many places. During the day SE England was mostly cloudy with isolated light showers. Most other districts were sunny, although it was cloudier with some showers in parts of Scotland and N and Cent Ireland. Some of the sunnier areas became quite mild. (Usk No.2 14.6C, Loch Glascarnoch 6.6C maximum, Katesbridge -4.8C minimum, Achnagart 7.6 mm, Morecambe 11.5 .)

Ground frost was widespread into the 26th with a widespread air frost across Scotland and N halves of Ireland and England. There was some rain across N Scotland overnight but much of the British Isles (away from W Ireland) was sunny with temperatures rising to around normal. Later in the day rain spread into S Ireland and SW England before spreading across Ireland, Wales and W England by midnight. 9 mm of rain fell at Sherkin Island during 0600-1800 GMT. (Charlwood 14.5C, Baltasound 5.4C maximum, Eskdalemuir -4.9C minimum, Culdrose 7.8 mm, Stornoway 10.0 h.)

Rain spread NE'wards overnight into the 27th and during the morning - affecting all areas of the British Isles. Ahead of the rain there was an air frost in parts of E Scotland. Brighter weather and showers followed the rain from the W. It was locally mild in the brighter areas, but mostly rather cold in the N - and windy in N Scotland. (Kew Gardens 15.9C, Craibstone 4.7C maximum, Aviemore -3.1C minimum, West Freugh 18.6 mm, Valley 5.8 h.)

On the 28th a lengthy period of rain crossed S Britain, and rain persisted in NE Scotland. Otherwise, there were bright spells and showers; these conditions spread to most southern counties during the day - which was generally quite cold. (Helens Bay 11.6C, Lerwick 3.1C maximum, Drumnadrochit -0.9C minimum, Kirkwall 20.8 mm, Tiree 8.5 h.)

Many places had a frost into the 29th, which was slight except in some northern areas. There were then sunny spells before showers and some longer spells of rain moved NE'wards across most S and Cent areas during the day. Isolated thunder occurred in S Britain. Away from some of the brighter areas, it was quite cold - very cold in N Scotland, where there was a little snowfall. (Hull East Park 12.2C, Lerwick 3.3C maximum, Dalwhinnie -7.0C minimum, Hurn 13.8 mm, Stornoway 12.2 h.)

Overnight into the 30th outbreaks of rain continued to move N'wards across northern regions overnight, turning to snow as they progressed across parts of N England and Scotland. S Britain had a mix of showers, a touch of frost overnight and a few fog patches. During the day, there was some sunshine, mainly in W areas, but further rain moved N'wards across S Britain, except Cornwall, and continued over Scotland. It was mostly cold or very cold, except locally in N England. (Levens Hall 10.6C, Balmoral 2.4C maximum, Dalwhinnie -2.3C minimum, Killowen 21.2 mm, Tiree 9.4 h.)

The 31st was mostly cold or very cold and cloudy with outbreaks of rain, and some snow in parts of Scotland. It was sunny across N Scotland. (Chertsey Abbey Mead 9.9C, Fylingdales 1.8C maximum, Baltasound -3.3C minimum, Okehampton 31.2 mm, Lerwick 11.3 h.)

British Isles weather, April 2018

Away from E England (where there was some rain and drizzle) there was a widespread ground frost into the 1st, accompanied by an air frost in many places. Some light snow fell overnight in SE Scotland. It was cloudy with further rain in E England for a while. During the day it was quite sunny in parts of Scotland but it was generally a cold day everywhere. Further snow fell in parts of Scotland during the day - which was dull in E and S England and in W Ireland. More general rain spread steadily NE'wards across England and Wales during the afternoon and evening, and this turned to snow in places away from the southernmost counties of England (Isles of Scilly 10.3C, Fylingdales 2.7C maximum, Tulloch Bridge -8.8C minimum, Isles of Scilly 22.8 mm, Tiree 12.2 h.)

An E'ly flow around low pressure to the SW of the British Isles led to an unsettled day on the 2nd. Scotland had a widespread ground frost and an inland air frost at first, followed by a mainly dry and sunny day. Elsewhere the low system brought frontal rain to most areas with snow over high ground, especially across N Wales, N England and S and Cent Scotland. It turned milder from the S. Travellers returning from bank holiday trips faced delays as heavy rain and snow closed roads. Up to 10 cm of snow covered parts of Scotland, N England and N Wales, while heavy rain in southern England led to some flood warnings. As of 1700 GMT the Environment Agency had issued 26 flood warnings and 205 flood alerts in England, and the Scottish Environment Protection Agency issued 1 flood alert and 2 flood warnings for people in Scotland; Natural Resources Wales had one flood warning and 12 flood alerts in place for Wales. Roads closed by floods and snow included the A616 in South Yorkshire in both directions between A628 (Hazelhead) and A6102 (Deepcar), the A628 Woodhead Pass in both directions due to snowy weather conditions between the A616 and A57 and four major routes in Derbyshire. (Filton 13.9C, Spadeadam 0.3C maximum, Altnaharra -6.0C minimum, Capel Curig 52.6 mm, Kirkwall 10.3 h.)

Low pressure remained centred to the SW of the British Isles on the 3rd. Parts of Cent Scotland had an air frost overnight, but across S England the night was relatively mild. Over most of Scotland, Northern Ireland and parts of N England it was very cold and wet, with snow in places - especially on the Scottish hills. Most of S Ireland, England and Wales was quite mild and showery - with sunny periods away from SE England and East Anglia; these regions remained rather dull. The showers were thundery in parts of Northern Ireland, Cent and NE England. Flood warnings were in place across the UK after the wet Easter weather caused many rivers to overflow their banks. The West Midlands, Northamptonshire, Cambridgeshire, Yorkshire and the North East were among the worst affected areas. In the morning, York's 16.5 tonne Foss Barrier was lowered in an attempt to combat the rising water level where the river joins the Ouse. The Environment Agency released a warning for properties along the Ouse, which overflowed its banks, saying flooding was expected and immediate action was required. In Wiltshire, the Avon was higher than usual and blue flood barriers were put into place along the banks. Multiple flood warnings were in place in the West Midlands along the river Severn. Three people and a dog were rescued from a car stuck in floodwater in Derbyshire, and firefighters helped residents in North Yorkshire after overnight flooding. (Hull East Park 16.2C, Salsburgh 1.1C maximum, Dalwhinnie -1.7C minimum, Salsburgh 22.0 mm, Camborne 7.6 h.)

On the 4th most places were cloudy with outbreaks of rain, and some further snowfalls in Scotland and N England. However, W and N Scotland had long sunny spells in places and W Ireland was also sunny. Later in the day, mostly dry weather extended SE'wards across Scotland and Northern Ireland, and the showers weakened in the south. It remained cold in N and Cent areas of the UK and was cool in the S. However, parts of E England turned milder. (Weybourne 15.3C, Salsburgh 0.0C maximum, Baltasound -1.1C minimum, Edinburgh Botanic Gardens 26.6 mm, Lerwick 11.6 h.)

Most inland areas away from S and E England had an air frost into the 5th as patchy rain (and snow in parts of Scotland) cleared away to the E. Most areas then had a dry and sunny day - although some showers affected the Northern Isles and cloud and rain spread into Ireland then SW Scotland later in the day. Parts of N Scotland had also had a few snow showers during the day. It remained generally cold in many areas during the day. (Gravesend 13.5C, Lerwick 4.7C maximum, Dalwhinnie -6.9C minimum, Carterhouse 10.0 mm, Altnaharra 11.9 h.)

Low pressure to the W on the 6th gradually drew air from the SE across parts of the UK during the day. There was a slight ground frost in E areas of the UK overnight with an air frost across parts of E and N Scotland. Overnight and during the day, rain across Ireland and SW Scotland spread into W Britain and across Scotland - leaving misty conditions in the evening over Ireland as it cleared away. Valentia reported 25 mm of rain in the 12 hours ending 0600 GMT. The best of the sunshine was to be found in the drier E parts of England - most notably across parts of East Anglia and Cent S and SE England, where it turned warm in places. (St Helier 17.5C, Resallach 5.4C maximum, Altnaharra -1.4C minimum, Banagher Caugh Hill 35.6 mm, Herstmonceux 10.1 h.)

Shallow areas of low pressure over and close to the British Isles led to a rather cloudy day on the 7th. Early mist and some fog was widespread across England, Wales and Ireland by dawn. Overnight, rain affected mainly NW and N Scotland and also parts of SW England and Wales. Further rain moved N'wards over W and N districts during the day, and there was also some rain in the extreme SE of England in the morning and evening. It was warm over much of E England. (Gravesend 19.4C, Pennerley 7.7C maximum, Kielder Castle 0.2C minimum, Liscombe 21.8 mm, Camborne 7.1 h.)

Mist and fog was widespread across the British Isles into the 8th with many areas of Ireland, Scotland, NW England and SE England having some rain or drizzle at times. This rainfall pattern continued during the day - although away from Ireland the SE corner of England falls were mainly light. Some of the brighter inland areas were quite warm. (Scolton Country Park 16.2C, Weybourne 7.2C maximum, Braemar -0.9C minimum, Thomastown 10.0 mm, Bude 10.6 h.)

Mist and fog were widespread by dawn on the 9th as a col brought mainly light winds to the British Isles overnight. During the day W and mainland parts of N Scotland had some sunny spells, as did N England, Wales and SW England - along with parts of E Ireland. Early rain over the SE corner of England spread NW'wards and reached most other areas of England by the evening; falls of rain also occurred over Ireland in the afternoon and evening. It was cold in the dull areas but warmer in the sunnier parts of Wales and SW England. (Porthmadog 16.2C, Lerwick 5.9C maximum, Braemar -2.5C minimum, Reading University 10.6 mm, Camborne 10.4 h.)

Frontal rain moved NW'wards during the 10th, slowly clearing away from the SE as it did so. The day was rather misty throughout and some areas, notably NE England, were rather foggy at times. Most areas had a dull day - although the Hebrides (ahead of the rain) and SE England (once the rain cleared) were notable exceptions. Under the cloudy skies the day was generally cool, although it became warmer in SE England later. (Herstmonceux 18.3C, Salsburgh 4.4C maximum, Balmoral 2.4C minimum, Bramham 25.4 mm, Stornoway 8.9 h.)

An E'ly flow on the 11th produced a cold, dull day close to E areas of the UK, although it was warmer in mainland N Scotland under sunny skies and also under sunshine close to the S coast of England. Most areas dawned rather misty with some fog in places and rain moved W'wards across S Britain overnight and during the morning, with some further rain from E Kent to the Midlands later in the day. (Plymouth 16.3C, Spadeadam 4.4C maximum, Baltasound 2.6C minimum, Odiham 14.4 mm, Herstmonceux 8.4 h.)

Mist and fog patches were widespread by dawn on the 12th following a night with some rain and drizzle across the S half of England and Wales. Rain moved N'wards across Cent and England and into S Scotland during the day, with further falls at times in S England. An area of heavy showers, briefly thundery, affected areas around Bodmin Moor and Dartmoor for much of the afternoon, and a trough brought some rain to parts of E England in the evening. It was a sunny day, warm in places, across N and Cent Scotland; elsewhere, particularly in E areas of the UK, it was cool in the surface E'ly flow. (Achnagart 16.8C, Spadeadam 3.9C maximum, Aviemore -1.2C minimum, Katesbridge 11.0 mm, Lerwick 13.0 h.)

England , Wales and Ireland were again misty around dawn on the 13th as an area of rain affected many areas overnight - although parts of S and W Ireland, SW England and W Scotland remained mainly dry. A mainly cloudy and misty day followed, with light rain in places. The day was another generally cool one. (Milford Haven 13.7C, Salsburgh 5.0C maximum, Baltasound 0.8C minimum, Sutton Bonington 18.4 mm, Shannon Airport 5.22 h.)

Widespread overnight mist and fog cleared during the morning of the 14th, except across Shetland where it remained dull all day. Other areas of N and E Scotland had spells of sunshine during the day, and parts of S England were especially sunny. It became warm inland during the afternoon, and some showers - heavy in places - affected parts of Kent, districts just to the west of London and areas of the Midlands during the late afternoon and evening. Later in the day, an area of low pressure approached SW Ireland and spread rain into W and SW Ireland in the evening. (Northolt 19.5C, Fair Isle 7.0C maximum, Frittenden 1.4C minimum, Winchcombe Sudeley Castle 3.6 mm, Charlwood 11.3 h.)

Parts of E Scotland had an air frost into the 15th while rain s[pread NE'wards across Ireland and into SW England and W Wales. Much of E Scotland, and most of England and Wales, was misty overnight with fog in E and S England for a time. During the day N and E Scotland and NE England were mostly sunny. Showery outbreaks moved NE'wards across other districts, but there were brighter intervals. Away from many coasts, it was mostly quite warm - especially in northern Scotland. Valentia had 24 mm of rain in the 24 hours ending 1800 GMT. (Kinlochewe 19.0C, Fair Isle 8.1C maximum, Altnaharra -2.6C, Liscombe 12.4 mm, Altnaharra 12.1 h.)

A deep area of low pressure drove fronts and rain across Ireland for much of the day on the 16th - MSL pressure was 993 mb in SW Ireland during late evening. Elsewhere, showery outbreaks in the west and north slowly faded, only for further thick cloud and rain to move in to these areas during the afternoon and evening; it became quite windy later rom the W. It was fairly sunny, and quite warm, over parts of E Scotland, Cent and E England. Valentia reported 28 mm of rain in the 12 hours ending 1800 GMT and much of W Ireland had a rather dull day. (Lossiemouth 17.7C, Fair Isle 6.5C maximum, Loch Glascarnoch 4.2C minimum, Eskdalemuir 9.4 mm, Herstmonceux 9.5 h.)

Low pressure persisted, but weakened, to the W of Ireland on the 17th. Outbreaks of frontal rain moved slowly E'wards across the British Isles, although E England remained largely dry until the evening. Parts of East Anglia and SE England had sunny spells ahead of advancing cloud - while much of Ireland and Scotland turned brighter and showery during the day. A S'ly flow led to some mild air reaching the E half of England, while showers in the W were thundery in places. (Santon Downham 20.9C, Lerwick 8.3C maximum, Lerwick 5.5C minimum, Cluanie Inn 31.2 mm, Guernsey Airport 10.8 h.)

A warm front moved slowly NW'wards on the 18th, giving outbreaks of (mainly) light rain and drizzle as it did so toW and N parts of the British Isles. Under thick cloud cover, it was an unseasonably warm night across much of England and Wales, away from the extreme SE parts of England, with minimum temperatures overnight above 12C in places. During the day much of the British Isles became very warm - with S and E England having 10-13 h of sunshine in most places. A five-year-old girl was killed when a "freak wave" washed her out to sea as she walked along the beach; the girl was walking with her mother and sister at Durdle Door in Dorset when she was swept into the water. (St James Park 25.3C, Fair Isle 10.7C maximum, Loch Glascarnoch 5.1C minimum, Capel Curig 9.4 mm, Shoeburyness 13.0 h.)

To the W of a cold front that pushed E'wards on the 19th it was a warm day with temperatures reaching over 25C in much of E and Cent England, away from the coasts. At Reading University a reading of 26.7C was the highest air temperature in the 110-year record for the site. 29.1C was recorded at St James's Park in central London during the afternoon, making it the hottest UK day in April since 1949. The highest recorded temperature for this month was 29.4C back in 1949 in London. Very dry air assisted the surge in temperature. The front gave little precipitation in the W and many parts of England, away from the extreme SW, had 12-13 h of bright sunshine. (St James Park 29.1C, Aberdaron 11.3C maximum, Eskdalemuir 3.7C minimum, South Uist 4.0 mm, Charterhall 13.6 h.)

Mist and some fog patches were widespread by dawn on the 20th across much of England, Wales and the S half of Ireland. A cold front gave small amounts of precipitation in some W areas overnight - these falls then also affected Scotland during the day but the front weakened as pressure - to 1025 mb over NW Wales by 2400 GMT. Most other districts were sunny and warm - temperatures reached 25C in London and SE England with much of England, Wales and S Ireland having long, sunny spells. It was cold and, at times, foggy on the windward Cornish and Devon coasts. (Frittenden 26.8C, Bude 9.0C maximum, Braemar 1.1C minimum, Kinlochewe 7.6 mm, Leconfield 13.3 h.)

Scotland along with N areas of Ireland, Wales and England had a ground frost on the 21st while mist and fog patches formed in more S'ly areas by dawn. There was some light rain and drizzle across parts of Ireland, W Wales and N Scotland overnight - and in S Ireland later in the day. Much of Ireland, Wales, W England and E Scotland had a sunny day. Some rain and drizzle fell over parts of England and Wales during the day, while in the evening areas of thunderstorms moved NE'wards into parts of Devon and Cent S England, travelling to the Midlands; another area affected Wales and later N England and S Scotland. A family had to move out of their house after lightning struck the roof setting it alight. The blaze broke out in Bembridge, on the Isle of Wight following a burst of heavy rain and lightning at about 2030 GMT. (St Helier 25.7C, Fair Isle 10.2C maximum, Aboyne -2.2C minimum, St Catherines Point 8.2 mm, Dyce 13.2 h.)

Thunderstorms, including falls of hail in places, moved NE'wards from Cent S England to the Midlands before dawn on the 22nd with another area affecting N England and S Scotland. Parts of N and Cent Scotland had a ground frost overnight, while over Ireland and W Scotland there were falls of frontal rain. These falls affected remaining areas of Scotland and also N England during the day. It was a warm day in E England ahead of the approaching cold fronts - although most areas away from Cent S and SE England, East Anglia and S Ireland were rather cloudy. This year's London Marathon was officially the hottest on record; more than 40,000 runners took part amid temperatures that rose to 24.1C in St James's Park, the Met Office said. A narrowing band of frontal rain crossed the country from the west; most of southern Britain just had a cloudier spell, but thundery showers developed at the southern end of the system over East Anglia in the afternoon. (Gravesend 25.0C, Lerwick 7.8C maximum, Drumnadrochit 0.7C minimum, Otterbourne Water Works 26.6 mm, Manston 12.0 h.)

Rainfall affected parts of Ireland, Scotland and N areas of England and Wales overnight into the 23rd. During the day most areas were cloudy, except for parts of East Anglia and SE England. Rain and drizzle became widespread across Ireland and Scotland later spread from Ireland into Wales and much of N and Cent England, with some falls in parts of SW and Cent S England later in the evening. (Heathrow 16.7C, Cluanie Inn 8.9C maximum, Charlwood 3.8C minimum, Cluanie Inn 16.6 mm, Shoeburyness 9.1 h.)

Much of N and Cent Scotland was bright with sunny periods, and some showers on the 24th. Elsewhere it was rather cloudy with widespread rain, especially heavy at times across Wales, S Ireland and Cent England. Cent S and SE England was mainly dry until late afternoon; much of S England was also misty. By late evening the rain was largely confined to E England and W parts of Scotland and Northern Ireland. (Gravesend 18.5C, Aberdaron 8.5C maximum, Aboyne 3.5C minimum, Gogerddan 25.8 mm, Tiree 10.3 h.)

Low pressure centred close to N Scotland on the 25th brought troughs with spells of rain across the British Isles. Overnight there was a ground frost in parts of E Scotland. The daytime showers were heavy with hail or thunder in places. There were sunny periods between the falls of rain - especially across S Ireland and S half of England and Wales. It was rather cool in the duller areas. (Heathrow 15.8C, Dalwhinnie 8.7C maximum, Balmoral -1.6C minimum, Coningsby 14.0 mm, Guernsey Airport 11.9 h.)

Sunny spells and showers affected most areas during the 26th, although falls were generally light across S areas of Ireland, Wales and England, with the best of the sunshine across W Wales and S England. Falls were widespread across Ireland, while during the evening rain spread from the S into S Ireland and SW England as an area of low pressure edged towards these areas from the S. (Heathrow 16.1C, Cluanie Inn 8.5C maximum, Aboyne 1.0C minimum, Cluanie Inn 32.0 mm, Aberdaron 12.0 h.)

Many parts of Scotland, N Ireland and N England had a ground frost on the 27th, with an air frost in places across N Ireland and S Scotland. During the day an area of low pressure moved E'wards across S England. Overnight rain moved NE'wards into much of Wales, S England and S Ireland; during the day this spread across most of England and Wales while Scotland and I Ireland had a showery day. It was cool across Wales and Cent England. (Frittenden 14.0C, Pennerley 5.1C maximum, Castlederg -2.2C minimum, Cardiff Bute Park 24.0 mm, Glasgow 13.5 h.)

Many northern areas had a frosty start to the28th, then most of the N half of the British Isles, along with Wales and SW England, had a cold day with sunny spells and scattered showers. Elsewhere the day was rather cloudy with some rain or drizzle. (Achnagart 14.7C, High Wycombe 7.2C maximum, Kinbrace -4.3C minimum, Weybourne 16.2 mm, Stornoway 13.0 h.)

The 29th was another generally cool day. There was an early air frost in parts of N Scotland, Cent Ireland and S Scotland while during the day the temperature failed to reach 8C in many parts of England. Patchy rain was largely confined to Ireland and Cent, E and many S areas of England during the day - these parts of England were also dull. The maximum temperature was just 7.7C at Reading University; in the past 110 years only 30 April 1939 (maximum 7.2C) and 1 May 1979 (maximum 7.2C) have been colder this late in the spring. (Kinlochewe 13.8C, High Wycombe 6.1C maximum, Kinbrace -5.0C minimum, Resallach 8.0 mm, Kinloss 14.3 h.)

Away from E England, East Anglia and SE England the 30th was a sunny day. Overnight there was an inland air frost as far S as parts of Cent Ireland and S Wales. There were isolated showers overnight and during the day in some areas; the exception to this was an area over London, and to the SE and E of London, where it was very wet, windy, cold and dull. A man died after being swept out to sea in Kent as heavy rain and winds affected the area. Two other men were taken to hospital after being washed from East Pier in Ramsgate by a large wave. Some trains in SE England were cancelled and roads were blocked by fallen trees. Also in Kent, firefighters rescued two adults and a baby from a car which was stuck in floodwater in Sutton Valence, while another man in Herne Bay was trapped when a tree fell on his car. Several flights leaving London City Airport have been delayed. A spokesman for the airport said air traffic control restricted the number of flights that could take off and land because of the poor weather conditions. (Glasgow 14.9C, Goudhurst 5.5C maximum, Kinbrace -6.0C minimum, Manston 39.4 mm, Glasgow 14.1 h.)
