British Isles weather, January 2021

There was a N'ly surface flow across most areas on the 1st. this led to a locally sharp frost from S Scotland, S'wards, and some freezing fog in the Midlands, S England and East Anglia overnight. It was sunny over much of S Scotland and parts of Ireland, as well as the Channel Islands. Most of England and Wales was dull and misty with patchy mostly light rain or snow, and N Scotland had wintry showers. It was mostly quite cold. (Isles of Scilly 8.2C, Leek 1.1C maximum, Larkhill -7.3C minimum, Fylingdales 24.2 mm, Cork Airport 6.9 h.)

A N'ly flow led to a cool day on the 2nd; there was quite a sharp frost in many places overnight, chiefly away from the more E'ly and SE'ly districts where it was cloudy with patchy drizzly rain or showers. Many places - especially S Scotland - had some sunshine during the day, but there were showery outbreaks over England and Wales and parts of E and N Scotland; It was mostly quite cold - locally very cold over a broad swathe of central Britain, with some snow. Dozens of people, including a two-year-old child, had to be rescued when they became stranded on rural roads; police and volunteers came to the aid of people whose vehicles were stuck in the Derbyshire Peak District and there were similar scenes in Cheshire where 22 people, had to be rescued from stranded cars. At around 2000 GMT Derbyshire Police reported "sudden snow" had left dozens of vehicles and their occupants stranded in the Goyt Valley. (Belmullet 8.0C, Drumalbin 0.0C maximum, Eskdalemuir -7.9C minimum, Loftus 18.0 mm, Dundrennan 6.2 H.)

There was a widespread air frost inland on the 3rd. During the day there were sunny spells, especially in the N and W, and showers - especially in the E and S of the British Isles. It was mostly rather cold (locally very cold where there was still a snow cover). (Isles of Scilly 7.3C, Pennerley 0.8C maximum, Loch Glascarnoch -9.1C minimum, Chillingham Barns 18.2 mm, Cork Airport 6.3 h.)

High pressure on the 4th over N Scotland (above 1032 mb for much of the day) led to a cold, E'ly surface flow. Air frost was widespread across Ireland, Scotland and N England at first. There was some sunshine, chiefly in the N and W of the UK and Ireland, but most places were cloudy. There were showers, wintry in places, towards the E coast of the UK, and mostly light rain in S areas of England, especially the SW. It was mostly quite cold - locally very cold in some N areas. (Isles of Scilly 7.3C, Dalwhinnie -1.8C maximum, Loch Glascarnoch -8.5C minimum, East Malling 11.4 mm, Tiree 6.0 h.)

The high pressure centre (1035 mb close to Stornoway at 0000 GMT) moved slowly SW'wards on the 5th. There was a widespread air first across N England and Scotland, with a sunny day following across many parts of Ireland and W areas of the UK. The day was cold with showers (some of them wintry) close to the E coast of the UK and more general rain and drizzle in East Anglia and SE England. A snow depth of 11 cm was reported at Loch Glascarnoch. (Magilligan 6.5C, Kinbrace -2.9C maximum, Kinbrace -7.6C minimum, Charsfield 11.0 mm, St Athan 5.7 h.)

On the 6th outbreaks of rain with some snow, mainly on high ground, over S Britain slowly gave way to brighter skies. Otherwise, there was a widespread air frost across the British Isles, this being especially severe in parts of N and Cent Scotland. There were then sunny spells across many areas of Ireland, Wales, N England and Scotland while there a few coastal showers in E parts of UK. Rain and hill snow spread into NW Scotland during the afternoon and evening. (Jersey Airport 7.1C, Drumalbin -1.9C maximum, Loch Glascarnoch -12.3C minimum, Kenley 12.6 mm, Aberdaron 7.1 h.)

Into the 7th there was a widespread sharp frost overnight (even -2.0C at Camborne). Then there were some bright spots, but outbreaks of (mostly) snow - and some rain over Ireland - extended slowly SE'wards across N and W districts, and there were a few coastal showers in eastern England. Freezing fog also affected some districts for much of the day, especially across the Midlands, the West Country and parts of Cent S England. Snow depths reported during the day include 14 cm at Loch Glascarnoch, 10 cm at Aviemore, 5 cm at Eskdalemuir and Spadeadam and 1 cm at Sennybridge. (Isles of Scilly 8.0C, Astwood Bank -2.0C maximum, Redesdale Camp -9.5C minimum, Baltasound 12.6 mm, Camborne 6.7 h.)

The cold spell continued on the 8th with mostly grey skies; there were further outbreaks of (mostly) snow over N England and Wales, which slowly died out, and some wintry showers near N-facing coasts. A few patches of persistent freezing fog affected Cent and E England. There were sunny spells over Scotland, Ireland and the extreme SE of England. Snow depths reported during the day included 13 cm at Loch Glascarnoch, 10cm at Shap Fell and Aviemore, 9 cm at Drumalbin, 8 cm at Spadeadam and 2 cm at Bingley. (St. Helier, Jersey and Isles of Scilly 6.9C, Loch Glascarnoch -3.5C maximum, Loch Glascarnoch -8.2C minimum, Loftus 24.2 mm, Cork Airport 7.5 h.)

Into the 9th there was a widespread frost overnight; it was severe over parts of Scotland and the far N of England but tended to be limited in many other districts by areas of cloud. Freezing fog affected parts of the Midlands and S England and persisted through the day in places. Many districts had some sunshine, though, whilst cloudier, milder weather spread across Scotland, with some rain. Reported snow depths included 13 cm at Loch Glascarnoch, 9 cm at Aviemore and Shap Fell, 8 cm at Eskdalemuir and Drumalbin, 7 cm at Bingley and Spadeadam, and 1 cm at Lough Fea and Dunkeswell. (Stornoway 8.5C, Brooms Barn -1.3C maximum, Eskdalemuir -11.9C minimum, Kinbrace 18.0 mm, Cork Airport and Jersey Airport 7.5 h.)

Into the 10th there was some slight frost overnight in N Scotland, as patchy rain edged away S'wards, but it was England and Wales that caught the hardest frosts (it was -4.5C at Culdrose at 0600 GMT), with areas of freezing fog. A mostly grey day followed, though there were a few brighter areas. Some rain crossed from the W, affecting particularly NW Scotland. Temperatures were mostly not far from normal in the W and N, but it stayed cold, locally very cold, over SE Britain, where a few freezing fog patches lingered into the afternoon.(Achnagart 8.7C, Wiggonholt 1.0C maximum, Okehampton -5.8C minimum, Resallach 23.8 mm, Cork Airport 4.1 h.)

On the 11th rain spread slowly SE'wards across most of the British Isles on a blustery, milder day. It was dry for most of the day over much of S and E England, and N Scotland was drier and quite cold; the colder air drifted S'wards over Scotland during the day with some falls of snow later across N Scotland and the Northern Isles. The day was cloudy everywhere, albeit with a little sunshine for a while in parts of the Northern Isles and around Fife. (Leuchars 10.9C, Kinbrace 1.0C maximum, Baltasound -4.1C minimum, Achnagart 47.2 mm, Lerwick 1.4 h.)

Mild and wet weather slowly cleared to the S and SE on the 12th, introducing a cold N'ly flow. Much of Scotland and northernmost England became frosty overnight, and the colder weather extended S'wards during the day - but SW England stayed mild, grey and damp. Elsewhere there was often quite a lot of cloud, with a few wintry showers near N coasts, but there were sunny spells in the N and E. SE England did not turn colder until the evening. It was a dull day across much of Ireland and S England. (Exeter Airport 11.1C, Lentran 0.7C maximum, Tulloch Bridge -5.9C minimum, Okehampton 25.8 mm, Boulmer 6.2 h.)

The 13th saw a warm sector spread across W areas of the British Isles from the SW. Much of the N and E of the UK had a frosty start. Mild, wet weather overnight in the SW spread slowly NE'wards across S and W regions during the day, but Scotland and NE England stayed cold with the rain turning to snow in places at it moved NE'wards. S Britain became rather drier during the day. The marked temperature contrast across the warm front ahead of the warm sector is illustrated by the 6pm temperatures of 1.6C at Watnall and 9.7C at Shawbury. The day was cloudy in all areas. (Shobdon 12.4C, Strathallan -0.1C maximum, Dalwhinnie -6.4C minimum, Ballypatrick Forest 28.4 mm, Kirkwall 1.8 h.)

On the 14th much of the N and E of the UK was cold and wet, with some snow, heavy overnight and at first during the day in parts of N England and S Scotland. It became generally drier late in the day. After overnight rain in many places, S and NW districts became drier and quite mild. Reported snow depths during the day included 11 cm at Bingley, Spadeadam and Strathallan. Away from Ireland it was a mainly cloud day. Motorists faced difficult driving conditions after heavy snow across parts of Scotland caused road closures. The A9 at Dunblane was closed for a time due to snow, while driving conditions on the M90 and M8 were reported as difficult. There were also been problems in the Scottish Borders where up to 30 cm of snow fell overnight. In the Borders several lorries got stuck on the A7 between Selkirk and Hawick, while difficult driving conditions were also reported on the A68 at the Carter Bar and Soutra. A coronavirus vaccination centre in Yorkshire has closed along with hundreds of schools as heavy snow hit the north of England; patients awaiting a jab at the Priory Campus in Lundwood, Barnsley, were urged not to travel and await new appointments. (Cardiff Bute Park 11.9C, Emley Moor -0.5C maximum, Drumnadrochit -1.0C minimum, St Bees Head 31.8 mm, Shannon Airport and Cork Airport 5.1 h.)

After a rather frosty start (although SW areas of England and Ireland remained free of air frost) into the 15th, most places were dry and cold with some sunshine. A few patches of freezing fog were slow to clear (if at all in one or two places) over Northern Ireland, Wales, the Midlands and Lincolnshire. Rain spread into Ireland and W Scotland in the evening, whilst many eastern and central districts became frosty again. Measured snow depths during the day included 11 cm at Bingley and Spadeadam and 10 cm at Strathallan. (Valentia 10.3C, Redesdale Camp -2.4C maximum, Ravensworth -11.8C minimum, Strathallan 11.8 mm, Boulmer 6.1 h.)

Into the 16th rain spread across most areas overnight, and after the earlier frost there was snow for a time in most E and NE districts of the UK (3 cm of snow lay at Wattisham at 0900 GMT). Drier, brighter and milder weather followed to most places by early afternoon. There were some showers, chiefly in the west and north, with more persistent rain in N Scotland, and also a further spell of rain over the Channel Islands. Pressure rose slowly from the SW during the day to about 1024 mb in Valentia by the evening. (Gosport Fleetlands 11.4C, Fylingdales 3.8C maximum, Redesdale Camp -5.4C minimum, Achnagart 38.2 mm, Aberdaron 5.3 h.)

The 17th was a rather cloudy with the best of any sunshine tending to be over E areas of the UK. Temperatures were close to the normal for mid-January. Outbreaks of rain, with some hill snow, spread across N areas of the UK while pressure remained high across S areas. (Isles of Scilly 9.8C, Fylingdales 3.7C maximum, Aboyne -1.4C minimum, Achnagart 15.6 mm, Shoeburyness 5.6 h.)

Overnight into the 18th there was a slight air frost in parts of S England. The day was fairly cloudy generally, with patchy rain, chiefly in the W and (with some hill snow) north, and temperatures not far from normal. There was some sunshine in NE areas of the UK. (Isles of Scilly 11.1C, Braemar 3.6C maximum, Frittenden -2.2C minimum, Achnagart 15.4 mm, Leuchars 4.3 h.)

There was an air frost in E Scotland into the 19th although elsewhere the night was quite mild in places; the overnight minimum temperature was 10.3C at Valentia. During the day the N half of Scotland was mostly dry with a little sunshine. Most other districts had spells of rain or drizzle, which was heaviest and most persistent over Wales and Cent Britain, resulting in some flooding. It was mild and windy in the south, but quite cold on the N edge of the rain band, whilst, after the overnight frost, temperatures struggled to rise further over parts of Scotland. Storm Christoph brought flooding across parts of Northern Ireland. (Charsfield 12.5C, Aboyne -0.1C maximum, Aboyne -6.5C minimum, Capel Curig 76.6 mm, Stornoway 4.2 h.)

Much of N and Cent Scotland had an air frost into the 20th, while it was a milder night elsewhere. At Scilly the overnight minimum temperature was 10.7C. The driest weather (apart from wintry showers in the N) pivoted to cover W and N Ireland and much of W Scotland. The heaviest and most persistent rain was over SE Scotland, N England and Wales, with serious flooding resulting in several districts. On the cold side of the frontal surface there was some snow, mainly on hills. Snow depths included 6 cm at Aviemore and 7 cm at Drumalbin. (Bude 12.1C, Dalwhinnie -0.2C maximum, Dalwhinnie -5.9C minimum, Capel Curig 87.8 mm, Tiree 2.8 h.)

Low pressure over the North Sea (storm Christophe; centre 967 mb near Northumberland at 0000 GMT) on the 21st moved slowly N'wards during the day (centre 950 mb near SW Norway at 1800 GMT). A few inland areas of Scotland, N England and N Ireland had a slight air frost at first as widespread rain across E areas of the UK moved into Scotland. This rain (and some snow) continued to move N'wards during the day, with a further area of rain affecting S parts of the UK later. Between the two precipitation areas there were sunny periods during the day. Heavy rain led to multiple major incidents and flood alerts being declared across England and Wales. People were evacuated from a large number of homes in South Wales, as Storm Christoph brought widespread flooding across England and Wales. About 2000 homes in the Didsbury and Northenden areas of Manchester, Ruthin and Bangor-on-Dee, North Wales, and Maghull, Merseyside, were also affected overnight. One hundred homes are also being evacuated in Skewen, near Neath, in West Glamorgan, because of flooding related to mine works. Many rivers are at "dangerously high levels", the Environment Agency said. Homes were also flooded in Cheshire following heavy rain and snow showers, with roads disrupted. Earlier in the day, Cheshire Fire and Rescue said it was in the process of rescuing 21 people by boat from Lea Court nursing home in the town of Warrington. Evacuations have taken also place in Northwich, Chester, Ellesmere Port and Tattenhall, according to Cheshire Constabulary. Natural Resources Wales has issued severe flood warnings for the River Dee at Bangor-on-Dee, Wrexham, and the Lower Dee Valley from Llangollen to Trevalyn Meadows. The East Coast Main Line was affected by floods between York and Darlington, with LNER saying all lines are blocked in the surrounding area. The weather also disrupted CrossCountry and Transport for Wales routes in Wales. (Manston 9.6C, Dalwhinnie 1.4C maximum, Tulloch Bridge -3.8C minimum, Fyvie Castle 29.4 mm, Cork Airport 6.7 h.)

A deep low to the E of Shetland drew a cool N'ly flow across the British Isles on the 22nd. There was an inland air frost in parts of England, Wales and Ireland while cloudier skies across Scotland led to rain and some snow overnight. During the day there were many showers over Ireland and the W half of the UK with further falls of snow across N Scotland. There were sunny spells in most areas, especially in E areas of England. Snow depths rose to 11 cm at Loch Glascarnoch and 4 cm at Sennybridge during the day. (Swanage 10.C, Loch Glascarnoch 1.1C maximum, Pembrey Sands -3.4C minimum, Aviemore 17.4 mm, Wattisham 7.6 h.)

There was a widespread air frost across the British Isles into the 23rd, with a few freezing fog patches during the morning over England (and all day locally in parts of Cumbria). There were falls of snow in parts of N Scotland and N Ireland overnight with mist and fog forming in Cent areas of England by dawn. The River Severn breached temporary flood barriers in Worcestershire, flooding homes; flood defences at Bewdley "failed" due to rising water levels in the early hours, the Environment Agency said. It was rather cloudy during the day across East Anglia and the East Midlands but most other areas has sunny spells. Areas of rain moved E across the Channel Islands and also E into W Ireland (with some snow here) later in the day; rain showers over W and N areas of the UK also fell as snow over N and W Scotland. It was a cool day over the N half of the British Isles. Reported snow depths included 17 cm at Loch Glascarnoch and 8 cm at Aviemore. (Isles of Scilly 7.7C, Spadeadam -0.9C maximum, Braemar -7.7C minimum, Rhyl 17.2 mm, Boulmer 7.0 h.)

There was a widespread air frost, away from SW Ireland, into the 24th. Rain, preceded by snow as the rain met cold air, pushed NE'wards across S and Cent areas of Wales and England in the early hours and during the day. Across Ireland, N England and much of Scotland there were sunny spells with some rain and snow showers across N Scotland. It was a cold day in all areas and snow lay in many areas once it had fallen; at 2100 GMT snow depths included 18 cm at Loch Glascarnoch, 2 cm at Bingley, 3 cm at Cranwell, 5 cm at Sennybridge, 9 cm at Coleshill, 17 cm at Wittering, 9 cm at Bedford, 6 cm at Liscombe and 8 cm at Ballypatrick Forest. Severe weather warnings were in place across much of the UK after large parts of the country saw heavy snowfall. Several coronavirus vaccination and testing centres were closed in England and Wales due to the conditions. Highways England warned that the snow had caused collisions on the M3, M27 and M25 in southern England, with the agency urging drivers to only travel if absolutely necessary. In Devon, a gritting lorry overturned on Dartmoor. Devon County Council urged people to avoid travel unless it was absolutely essential and not to travel to find snow. (Isles of Scilly 7.5C, Lake Vyrnwy -1.2C maximum, Dalwhinnie -11.4C minimum, Milford Haven 20.8 mm, Boulmer 7.3 h.)

On the 25th, after a sharp frost, most places were quite sunny and rather less cold, although frost returned widely in the evening. There were a few coastal showers in the N, E and SW, and a patch of rain moved into SW Scotland late in the day. (Isles of Scilly 8.1C, Sennybridge 1.4C maximum, Katesbridge -10.4C minimum, Resallach 16.2 mm, Jersey Airport 8.2 h.)

Lying snow finally melted from many S areas on the 26th. Rain and drizzle moved NE'wards across the British Isles and, except in the NE, it slowly became milder after a sharp frost in many places. There was some snow in parts of Scotland and, away from Shetland, it was a dull day. (Isles of Scilly 11.0C, Braemar -1.8C maximum, Dalwhinnie -9.5C minimum, Isles of Scilly 15.6 mm, Lerwick 6.0 h.)

On the 27th N and E areas of Scotland were quite cold with some wintry showers. Elsewhere, it was mostly mild, but cloudy with patchy drizzle and areas of fog over the higher ground. Heavier rain spread from the SW of the British Isles late in the day. Snow depths at 2100 GMT includes 15 cm at Loch Glascarnoch and 9 cm at Aviemore, but only 0.5 cm at Lerwick. (Valentia 11.9C, Dalwhinnie 1.1C maximum, Baltasound -6.6C minimum, Gt Cumbrae Millport 9.2 mm, Lerwick 4.3 h.)

Into the 28th much of the northern half of Scotland was clear and frosty overnight, while a large area of often heavy rain moved NE'wards across other areas and into W and S Scotland; there was snow in some of the more N'ly locations. A weaker area of rain and snow continued N'wards across Scotland during the day, and further areas of rain, again often heavy, followed from the SW across the rest of the British Isles during the afternoon and evening - after a little sunshine in parts of the S. It was mild in the S, but mostly rather cold in the N and E. Snow depths at 2100 GMT included 19 cm at Loch Glascarnoch and 8 cm at Aviemore. (Pershore College 14.2C, Balmoral 0.3C maximum, Braemar -6.8C minimum, Killowen 33.2 mm, Lerwick 4.1 h.)

Into the 29th rain moved northeast across most places overnight; it was heavy in places, and there was some snow in the N. It then stayed fairly cloudy over much of the country, with further patchy rain; there were also brighter intervals. More general rain spread into the SW of the British Isles again in the evening. It was mostly rather cold in the north and rather mild in the south. (Gosport Fleetlands 12.1C, Dalwhinnie 0.5C maximum, Lerwick -4.6C minimum, Dyce 19.8 mm, Tiree 6.3 h.)

On the 30th two bands of rain initially moved NE'wards across S areas, with some snow in the northern one over the Midlands and Wales. As they gave up their N'wards push in the face of cold air and retreated S'wards during the afternoon they rapidly weakened, and most places were dry by evening. Apart from isolated wintry showers, and following a sharp frost, Cent and N areas of the UK were dry with some sunshine. Except in the most N and S areas. there was a very cold, blustery easterly wind over much of the country. Reported snow depths included 18 cm at Loch Glascarnoch and 9 cm at Aviemore. (Culdrose 11.1C, Balmoral -0.2C maximum, Altnaharra -10.1C minimum, Plymouth 26.8 mm, Tiree 6.4 h.)

Overnight into the 31st there was a widespread frost that was severe in some N areas of Scotland. A cold day followed for most, with locally persistent frost, especially over N Scotland. The most SW'ly regions were quite mild, both by night and day. The overnight minimum temperature at Valentia was 6.0C. Apart from a few wintry showers, mainly near E and N coasts, it was dry over most of NE England and Scotland, with some sunshine - the best of this over N Scotland. Rain, with a little snow in places, moved NE'wards across most other districts, but it became generally drier late in the day. Snow depths at 2100 GMT included 18 cm at Loch Glascarnoch and 10cm at Aviemore. (Valentia 11.6C, Aviemore -3.0C maximum, Braemar -13.0C minimum, Culdrose 18.4 mm, Loch Glascarnoch 6.7 h.)

British Isles weather, February 2021

The 1st dawned after a widespread air frost across Scotland and in parts of N and Cent England it was a very cold start to the day over N Scotland. Over N England and N Scotland it was a sunny day with some wintry showers in N Scotland. Ireland and S Britain was mostly dull and rather cold, but it was milder in the SW England. An area of rain spread from Ireland into SW Scotland during the day, and further rain spread into Ireland and the more W'ly and SW'ly parts of the UK late in the day, and moved steadily NE'wards in the evening. 11 mm of rain fell at Sherkin Island during 0600-1800 GMT while snow lay 18 cm deep at Loch Glascarnoch early in the day. (Isles of Scilly 11.3C, Dalwhinnie -0.6C maximum, Altnaharra -10.5C minimum, Camborne 9.4 mm, Waddington 7.8 h.)

Into the 2nd as the rain continued NE'wards overnight, it turned to snow over a previously frosty N England and S Scotland, whilst there was a locally very severe frost further north. Much of N England, Northern Ireland and Scotland then had a mix of rain and snow through the day - although much of it was light. N Scotland had just a few wintry showers, and a little sunshine. S Britain was mild with some sunshine and a few showers, but an area of quite heavy rain moved NE'wards during the afternoon and evening; parts of East Anglia and southern England only had a little rain. The persistence of fog led to a cold day in parts of the N Midlands. (Cardiff Bute Park 14.2C, Spadeadam 0.5C maximum, Altnaharra -12.1C, Capel Curig 35.6 mm, Lerwick 4.0 h.)

N Scotland had further wintry showers on the 3rd, but most of Scotland, Northern Ireland and northern England had a blustery easterly wind and persistent rain or snow. Further S the winds were more W'ly in direction, due to a low centred over Ireland (984 mb to the W of Valentia at 1200 GMT). Another rain area affected central southern and southeast England for a few hours, but most of S Ireland and S Britain was quite mild with a little sunshine and a few showers. By the evening snow depths included 19 cm at Aviemore, 16 cm at Loch Glascarnoch, 10 cm at Aboyne and 17 cm at Spadeadam. (Rostherne 11.3C, Braemar 0.2C maximum, Altnaharra -3.9C minimum, Ballypatrick Forest 45.6 mm, Aberdaron 5.6 h.)

On the 4th further areas of occasionally heavy windblown rain and (mostly) hill snow affected central and northern districts - but Shetland had some more sunshine. There was patchy fog and frost at first in S areas of the UK, then it was still quite mild here with some sunshine, but bands of showery rain moved NE'wards here and across Ireland at times during the day. Thirty-two people were rescued after vehicles became trapped overnight in snow on the A835 in the Highlands. Highland Council and mountain rescuers assisted emergency services reaching the 22 vehicles at the scene at Loch Droma. Snow drifts of 2-3 m blocked the A835 between Ullapool and Garve. Snow depths reported in the evening included 17 cm at Loch Glascarnoch, 19 cm at Aviemore and 14 cm at Aboyne. (St Helier 11.6C, Loch Glascarnoch 0.5C maximum, Altnaharra -3.1C minimum, Logan Botanic Garden 51.0 mm, Aberdaron 7.3 h.)

Low pressure remained centred over or close to Ireland throughout the 5th. Rain and hill snow, and a blustery E'ly wind, continued over much of Scotland, especially the E and S, Northern Ireland and northernmost England. After an overnight ground frost in parts of the Midlands and Cent S England, further south it was showery, and it turned rather colder in the W, but E and S England were still quite mild and some places here and in S Ireland - were mostly sunny. (Kew Gardens 11.7C, Loch Glascarnoch 1.0C maximum, Shawbury -0.3C minimum, Tyndrum 46.6 mm, Guernsey Airport 8.5 h.)

On the 6th there was some sunshine in the W and S of the UK, but most of the British Isles was cloudy or dull. Fog and frost affected parts of Cent and E England overnight, and the fog persisted all day in parts of the Midlands. Outbreaks of rain occurred quite widely (although W Ireland remained mostly dry), with snow in the north; it was particularly wet over E and N England. It was a little on the mild side in the S, but mostly quite cold elsewhere, and blustery in the N. Evening snow depths included 15 cm at Loch Glascarnoch, 16 cm at Aviemore and 17 cm at Aboyne. (Plymouth 10.1C, Balmoral 0.1C maximum, Benson -3.6C minimum, Bingley 46.2 mm, Jersey Airport 7.1.h)

The 7th dawned after an inland air frost in Scotland and areas of N England. The day was cold, locally very cold, with a fresh NE'ly wind. After overnight rain in the E areas of the UK, there were outbreaks of snow over Cent and E districts, though much of it was light away from the E coast and hilly regions. W areas of the UK had the best of any sunshine. After some heavy snowfalls in Kent, evening snow depths included 15 cm at Loch Glascarnoch, 17 cm at Aviemore, 21 cm at Aboyne and 15 cm at Manston. (Sherkin Island 7.5C, Braemar -1.5C maximum, Braemar -2.7C minimum, St Catherine's Point 11.4 mm, Stornoway 3.9 h.)

The 8th was very cold with spells of snow, especially over Cent and E districts of the UK, where many places were frosty throughout the day especially in East Anglia and SE England. It was a sunny day over W Scotland. Heavy snow left 29 cm of snow on the ground in Aboyne by the evening, with 19 cm lying at this time at Loch Glascarnoch, 11 cm at Altnaharra, 18 cm at Aviemore, 10 cm at Spadeadam, 28 cm at Andrewsfield and 14 cm at Manston. There were several road accidents in Scotland as well as "significant disruption" to rail routes, including from Edinburgh to Glasgow. Some coronavirus vaccination centres were closed due to the conditions in Essex and Suffolk. More than 380 schools in Norfolk and 200 schools in Suffolk are closed to all pupils. Dozens of schools were also closed in Scotland, including more than 40 in the Aberdeenshire area. Snow and ice caused disruption across the Greater Anglia rail network, including between Norwich and London, while Southeastern closed some lines in England. The AA said "treacherous driving conditions" had caused "numerous" accidents, with some roads closed in Norfolk, Lincolnshire, Cumbria, Derbyshire and Hertfordshire. Police in Norfolk warned of "blizzard-like conditions" with snowdrifts and blockages on many roads. (Isles of Scilly 4.5C, Wych Cross -2.5C maximum, Fyvie Castle -7.8C minimum, Houghton Hall 4.6 mm, Dundrennan 7.6 h.)

After a very severe frost in some N areas, the 9th was generally very cold with snow at times, heaviest in the E (Scilly had rain). Frost persisted all day in various districts, especially in the N - which also had the best of the sunshine. Low pressure to the S of the UK led to a brisk E'ly flow across all areas. Lying snow depths in the evening included 18 cm at Loch Glascarnoch. 17 cm at Aviemore, 12 cm at Lossiemouth, 40 cm at Aboyne, 12 cm at Dyce, 19 cm at Strathallan, 18 cm at Wattisham, 23 cm at Andrewsfield and 14 cm at Manston. (Isles of Scilly 5.3C, Altnaharra -5.5C maximum, Altnaharra -16.7C minimum, Charsfield 7.2 mm, Valley 7.9 h.)

The 10th was mostly cold or very cold with sunny spells, and further snow showers - especially over Cent and E England. It was particularly sunny across N and W Scotland. Scotland has faced another day of travel disruption after temperatures continued to plummet overnight. Further heavy snowfall and freezing conditions have caused problems on the roads and across the rail network. The disruption included HGVS stuck on the A720 eastbound between Calder and Baberton, and on the A92 at Lochgelly. Dozens of schools across Fife, Moray and the Highlands remain closed to all pupils - including the children of key workers and vulnerable children. In Edinburgh, waste collections were suspended so staff can help with the snow-clearing effort. Snow depths reported at 2100 GMT included 18 cm at Loch Glascarnoch, 17 cm at Aviemore and Strathallan, 10 cm at Lossiemouth, Dyce, Edinburgh Gogarbank and Marham, 35 cm at Aboyne, 13 cm at Redesdale, 11 cm at Albermarle, 16 cm at Wattisham, 20 cm at Andrewsfield and 14 cm at Manston. (Isles of Scilly 5.0C, Kinbrace -5.5C maximum, Altnaharra -17.1C minimum, Craibstone 4.4 mm, Kirkwall 7.7 h.)

Into the 11th a severe frost was widespread, with exceptionally low temperatures over many parts of Scotland. There were a few snow flurries in the SE corner of England. The day was mostly dry and bright or sunny with temperatures struggling to reach freezing point. It turned cloudier from the west across southern districts, with some rain and snow in the far SW of the UK. Braemar (with -23.0C) recorded the second lowest temperature recorded in the UK in February - only beaten by its own -25C on the 23rd in 1955. The reading today was also the UK's lowest temperature since 30 December 1995. ScotRail said the winter weather was causing major problems for its services. Malcolm MacIntyre, of the Braemar Mountain Rescue Team, told BBC Radio's Good Morning Scotland: "It is a beautiful morning actually and it is really cold. "The snow is squeaky, which always signifies that it is really cold." About 29,000 properties were left without water on Wednesday night in the east end of Glasgow after a mains pipe burst. Firefighters worked through the night to tackle a large wildfire in the Western Isles. The blaze on Benbecula was reported at 1530 GMT on Wednesday and extended across about 1 km at its height. Evening snow depths included 18 cm at Loch Glascarnoch, 17 cm at Aviemore, 31 cm at Aboyne and 18 cm at Andrewsfield. (Bridgefoot 5.4C, Braemar -6.3C maximum, Braemar -23.0C minimum, Balmoral 4.8 mm, Glasgow 8.4 h.)

Pressure remained high to the E of the British Isles on the 12th. The overnight frost was not quite as severe in N districts, and daytime temperatures rose above freezing nearly everywhere - but stayed below freezing in parts of England and Wales. Many districts were bright or sunny, but there were wintry showers in parts of the E and S, and there was a little rain or sleet in SW England. Heavy snow showers affected parts of eastern Scotland in the evening while rain fell across W Ireland later in the day. This area of rain and cloud also introduced milder air into W Ireland. Evening snow depths included 37 cm at Aboyne, 18 cm at Loch Glascarnoch, 17 cm at Aviemore and 16 cm at Wattisham. (Valentia 8.5C, Wych Cross -1.0C, maximum, Kinbrace -15.4C minimum, Leuchars 7.0 mm, Kinloss 7.9 h.)

High pressure to the E on the 13th (MSL pressure 1032 mb across Shetland) drew a S'ly flow into the British Isles. S Ireland and Scilly saw temperatures rising above 10C; otherwise, it was very cold, and some rain or snow, much of it light, spread E'wards, after a sunny start in the E. A strong wind added to the severity of the cold in the west and north e.g., at midday St Bees' Head had -0.5C with a 30 kn mean wind speed (and Gt Dun Fell -9.1C and 39 kn). Freezing rain was also reported from several districts. Evening snow depths included 32 cm at Aboyne, 23 cm at Dyce and 15 cm at Aviemore and Loch Glascarnoch. (Valentia 12.4C, Pennerley -3.1C maximum, Loch Glascarnoch -6.5C minimum, Culdrose 11.4 mm, Wattisham 6.7 h.)

The 14th was a rather cloudy day in a brisk S'ly airflow. At 1200 GMT pressure varied from about 988 mb at Belmullet to 1029 mb in E Kent. Bands of rain moved across from the W, and there was some snow and, locally, freezing rain for a time in the E and N. It gradually became milder (very mild over Ireland), but E England had a very cold day, exacerbated by a keen S'ly wind which was strongest in the N. Evening snow depths included 26 cm at Aboyne and 13 cm at Wattisham. (Gurteen 13.8C, High Mowthorpe 0.9C maximum, Dalwhinnie -4.9C minimum, Whitechurch 40.4 mm, Shannon Airport 3.7 h.)

Overnight in to the 15th conditions were frost-free at low levels; snow thawed rapidly as rain cleared slowly SE'wards. The day was mild and fairly cloudy with some sunshine. Showery outbreaks retreated N'wards over Scotland, whilst further rain moved into S areas of Ireland and England during the evening. Evening snow depths included 18 cm at Aboyne, 3 cm at Dyce and 2 cm at Aviemore and Loch Glascarnoch. (Kew Gardens 13.9C, Braemar 5.5C maximum, Albemarle 0.1C minimum, Wych Cross 14.4 mm, Casement Aerodrome 5.6 h.)

The 16th was fairly cloudy and mild with showery outbreaks, but became generally brighter and drier from the W during the day; the best of the sunshine was over E Scotland. It was quite windy in NW areas of the UK due to a low centred close to NW Scotland during the day. By 2100 GMT the snow depth at Aboyne had fallen to 9 cm. (Myerscough 13.6C, Braemar 6.4C maximum, Cassley 1.2C minimum, Achnagart 31.6 mm, Kinloss 7.9 h.)

On the 17th rain crossed the British Isles from the west overnight and at first. Patchy, drizzly rain never got clear of S counties, and rain then returned N'wards over S and Cent districts of the UK and Ireland during the afternoon and evening. This followed a bright period over much of Scotland, Ireland, N England and N Wales, although there were heavy, lengthy showers over W and N Scotland, with isolated thunder and some snow. SE Britain had a dry evening. It was breezy, and mild in the south with more seasonable temperatures in the north. (Pershore College 13.3C, Lentran 4.6C maximum, Fyvie Castle -0.7C minimum, Balmoral 32.8 mm, Dyce 6.5 h.)

Rain cleared E'wards during the morning of the 18th, with sunny spells following; there were some showers, especially in the N of the UK. It was mostly quite mild, and strong winds in the N and W eased. (Shoeburyness 11.6C, Dalwhinnie 4.3C maximum, Banagher Caugh Hill 0.7C minimum, Achnagart 37.4 mm, Guernsey Airport and St Athan 6.2h.)

The 19th was mostly cloudy and areas of rain drifted E'wards, affecting especially W and N areas of the British Isles. It became increasingly mild, but was windy due to low pressure to the W of Ireland. Away from parts of W Ireland and E Scotland it was a sunless day. (Edinburgh Botanic Gardens 13.2C, Inverbervie 6.6C maximum, Westonbirt 1.0C minimum, Keswick 65.4 mm, Kinloss 1.6 h.)

On the 20th many places had outbreaks of rain, with the Lake District and Wales particularly wet, but much of E and SE England was dry and it was quite sunny from London E'wards; there was also some sunshine over N Scotland. It was rather windy, but temperatures were mostly a few degrees C above normal, especially in SE England. Parts of the UK have been hit by a month's worth of rain leading to flooding in some areas. Railway lines were blocked in places. There was disruption on rail networks in Wales and south-west England due to flooding. Flooding of the railway at Roche in Cornwall meant Great Western Railway trains were unable to run between Newquay and Par. In Wales, flooded tracks between Abercynon and Merthyr Tydfil left all lines closed. Buses were expected to replace trains between Pontypridd and Aberdare until the end of the day due to flooding of the railway between these stations. Flooding between Hereford, in Herefordshire, and Newport, in Wales, was also causing disruption to journeys. 127.6 mm of rain fell at Llyn-y-Fan, Carmarthenshire, between 0600 GMT/19th 0800 GMT/20th, and 115 mm fell at Treherbert in Mid-Glamorgan. (St James Park 15.6C, Bridlington 7.8C maximum, Altnaharra -0.3C minimum, Libanus 70.0 mm, Shoeburyness 6.0 h.)

On the 21st patchy rain moved E'wards across England and Wales overnight, then back W'wards during the day; it mostly did not amount to much, and tended to die out, but parts of SW England were quite wet. There was some sunshine in SE England. Much of Scotland and Ireland was bright or sunny with a few showers, although parts of W Scotland had more persistent rain at first. (Weybourne 15.9C, Dalwhinnie 7.3C maximum, Cassley 2.1C minimum, Achnagart 13.8 mm, Cork Airport 7.4 h.)

On the 22nd rain moved E'wards across much of S and E Britain during the first few hours of the day, although much of it was light. It was slow to clear the extreme SE of England, but the clearer skies in the NW UK spread to most of the UK and Ireland, with sunny periods developing. It was mostly quite mild. In Kent there were reports of dust falls in the S'ly airflow. (Hawarden 13.4C, Dalwhinnie 6.7C maximum, Derrylin Cornahoule -1.3C minimum, Libanus 11.6 mm, Ronaldsway 8.4 h.)

On the 23rd rain returned to many W and N districts of the British Isles as low pressure centred W of Ireland pushed fronts E'wards, but SE Britain was dry and fairly sunny. It was mild, locally very mild, but windy. Dust from the Sahara caused colourful sunrises and sunsets across the UK. Red skies were seen over parts of the UK in the morning. (Rhyl 15.0C, Dundrennan 8.8C maximum, Kielder Castle -0.6C minimum, Keswick 59.0 mm, Shoeburyness 8.9 h.)

Much of the British Isles was cloudy on the 24th, and outbreaks of rain affected chiefly the SW peninsula, much of Wales and parts of Ireland, S Scotland and N England (especially the Lake District); there were some brighter intervals elsewhere, as well as a few patches of light rain. Some E districts of the UK were quite sunny. It was mild - warm over much of E England - and the blustery winds eased. In parts of the N Midlands Saharan dust was observed to fall. (Santon Downham 18.4C, St Bees Head 7.2C maximum, Loch Glascarnoch 4.1C minimum, Capel Curig 49.6 mm, Manston 7.0 h.)

On the 25th SE England was cloudy with some, mostly light, rain. During the day an area of high pressure built NE'wards into SW areas of the British Isles. Apart from some showers in the NW Scotland and W Ireland, most other districts were dry with long sunny spells. It was a fairly mild day. (Pershore 13.4C, Spadeadam 6.6C maximum, Fyvie Castle 1.7C minimum, Kinlochewe 10.8 mm, Aberdaron 9.8 h.)

On the 26th, apart from a little rain on Shetland, it was dry and most places were sunny and became quite mild, after a fairly widespread mostly slight frost, with one or two fog patches in S and Cent England and Wales. At 1200 GMT MSL pressure was centred at 1040 mb to the S of Cornwall. Low cloud and fog affected a few Irish Sea coastal areas. (Fyvie Castle 14.4C, Eskdalemuir 7.4C maximum, Benson -4.7C minimum, Lerwick 1.8 mm, Jersey Airport 10.1.h )

The 27th was mostly sunny (except across Ireland and SW Scotland), after the clearance of some fog and low cloud, mainly in the SW of the UK. There was an overnight frost over, chiefly, England and Wales, then it became generally mild - locally very mild in the E. At 1200 GMT MSL pressure was centred at 1043 mb over SW Wales. (Craibstone 14.9C, Cromer 7.3C maximum, Benson -4.1C minimum, Cassley 3.2 mm, Jersey Airport 10.2 h.)

Into the 28th there was a mix of cloud, frost and, over much of England, Wales and Ireland, fog overnight. Most places eventually became quite sunny with temperatures rising to near or rather above normal. At 1200 GMT MSL pressure was centred at 1040 mb just to the E of N Lincolnshire. (Chivenor 14.0C, Weybourne 6.1C maximum, Kinbrace -5.8C minimum, Tiree 0.4 mm, Aberdaron, Yeovilton and Camborne 10.2 h.)

British Isles weather, March 2021

High pressure centred over the North Sea led to a generally dry day on the 1st. S and E Scotland, much of the Midlands, N England, N Wales and E Ireland had an overnight air frost. There was fog at first in parts of Ireland, Cent and E Ireland and some places stayed misty or foggy for much of the day. Snow grains were reported from Bedford and High Wycombe. Many W areas of Ireland and the UK reached a mild 10C during the day with long, sunny spells in places here during the day. (Porthmadog 14.9C, Emley Moor 3.0C maximum, Shap -4.9C minimum, Lerwick 0.8 mm, Aberdaron 10.5 h.)

The area of high pressure declined across the British Isles on the 2nd, allowing an area of frontal rain to spread into the extreme SW of England in the later afternoon and evening. Inland areas of Scotland, N England, N Wales and E Ireland had an overnight air frost. During the day, some places, especially in the W of the UK, were fairly sunny and mild, otherwise it was quite cloudy and cold. Snow grains fell at Spadeadam. (Capel Curig and Jersey Airport 13.3C, Emley Moor 2.1C maximum, Altnaharra -6.6C minimum, Isles of Scilly 1.4 mm, Morecambe 10.0 h.)

While high pressure persisted into the 3rd, a cold front moved S into Shetland later in the day, and a shallow area of low pressure affected the SW of the UK. Many areas away from Ireland had an overnight air frost, mainly in the N half of the UK. There was also a fair amount of fog in the morning, especially over Cent and E England, with only a slow improvement in visibility for some. Generally, it was a grey, cold day, although temperatures were near or rather above normal over S England and S Wales. Outbreaks of rain drifted N'wards over S England and Wales, later moving into the Midlands and East Anglia. Patchy light rain also drifted SW'wards into N and E Scotland. The 7.6 h of sunshine at Shap Fell was very localised - presumably above the inversion. There was some light snow later in the day at Loch Glascarnoch. (Camborne 13.5C, Dalwhinnie 0.6C maximum, Braemar -7.6C minimum, Milford Haven 13.2 mm, Shap 7.6 h.)

On the 4th areas of rain and showers affected E areas of the UK, with falls across N Ireland later in the day. It was generally dull and rather cold although parts of N England and W Scotland did see some sunshine. (Jersey 10.8C, Dalwhinnie 2.2C maximum, Shap -2.6C minimum, Bedford 15.4 mm, Tiree 5.8 h.)

The 5th was mostly dry, fairly cloudy and quite cold, with an overnight air frost in parts of Scotland, NW England and N Wales in particular. There were some brighter spots in the extreme SE, W and N of the UK. (Valentia 10.4C, Lake Vyrnwy 2.9C maximum, Loch Glascarnoch -7.1C minimum, Lerwick 2.0 mm, Valley 8.6 h.)

High pressure persisted on the 6th, central pressure 1036 mb at 1200 GMT over NW England. There were still large areas of cloud and it was mostly quite cold following a widespread inland air frost, but many places had some sunshine; W Scotland and N England were rather dull, however. Patchy light rain moved slowly SE'wards into Scotland where it was generally less cold than of late. (Belmullet 10.3C, Dalwhinnie 2.9C maximum, Braemar -8.5C minimum, Stornoway 5.2 mm, Jersey Airport 10.4 h.)

Many places were frosty overnight into the 7th, then there was again a mix of cloud and sunnier patches, whilst outbreaks of rain moved SE'wards into Scotland. Temperatures were mostly rather higher than of late, but it was still quite cold in the south after a locally sharp overnight frost. (Killowen 12.7C, Okehampton 3.1C maximum, Sennybridge -7.7C minimum, Wick Airport 19.0 mm, Dublin Airport and Casement Aerodrome 10.0 h)

The 8th dawned after another frosty night in many southern districts of the UK, followed by a dry day with varying cloud cover; the best of the sunshine was in SW England and S Wales. Patchy rain moved SE'wards from Scotland and Northern Ireland across N and E England; drier weather followed, with some brighter intervals. Many places became quite mild, but there were still colder pockets, notably in Shetland and parts of the south - chiefly those areas which saw little of the sunshine. (Murlough 13.2C, Lerwick 4.8C maximum, Okehampton -5.5C minimum, Dunstaffnage 13.6 mm, Camborne 8.6 h.)

On the 9th, after some early frost, Cent and E England was mostly sunny and became quite mild. It slowly clouded over from the west over most of the British Isles, and wet and increasingly windy weather spread slowly E'wards across a mostly rather chilly W and N. Thousands of properties across Skye and North and South Uist were left without power after high winds due to a deep area of low pressure centred to the W of the Western Isles (about 964 mb) in the evening. Winds gusted to more than 70 mph over the Western Isles and west Highlands. (St James Park 14.4C, Lerwick 6.2C maximum, Benson -4.6C minimum, Tyndrum 20.6 mm, East Malling 10.2 h.)

Rain and drizzle spread to all areas overnight into the 10th, and during the morning, with copious rainfall in upland western regions. Scotland became brighter, although very showery. It was windy, and quite cold in the frontal rain; temperatures rose above normal behind the fronts. Away from the N half of Scotland it was a dull day. (Hawarden 13.7C, Dalwhinnie 6.0C maximum, Dalwhinnie 0.4C minimum, Capel Curig 80.2 mm, Kinloss 4.6 h.)

Into the 11th it was a very windy night over Ireland, England and Wales; there were gusts of up to 85 mph on the Lleyn peninsula. Winds eased only slowly on a showery day throughout the British Isles with some sunshine and mostly seasonable temperatures (after a very mild night in the south). There was snow on northern hills, hail in places and isolated thunder. The roof was blown off a block of flats in Oxford by gusty winds. Thousands of homes were left without power after strong winds and heavy rain hit Wales. Western Power Distribution said about 3,000 of its customers had been left without power on Thursday morning, but most were restored by the afternoon. (Writtle 13.2C, Lough Fea 5.3C maximum, Dalwhinnie 2.1C minimum, Lake Vyrnwy 32.6 mm, Guernsey Airport 6.8 h.)

The 12th was another blustery, showery day with snow the northern hills of Scotland and Northern Ireland, hail in places and isolated thunder. There was some sunshine, but it was mostly rather cold. Longer outbreaks of rain spread from the west across Ireland in the afternoon and into Wales and W areas of the UK in the during the evening. (Teddington Bushy Park 11.7C, Dalwhinnie 2.8C maximum, Dalwhinnie 0.1C minimum Lake Vyrnwy 29.4 mm, Kinloss 8.5 h.)

Rain spread across the UK overnight into the 13th, although the N half of Scotland stayed clearer with some showers and frost in places. A low centred at 979 mb at 0000 GMT over SW Scotland quickly moved away E'wards into the North Sea. It was then another mostly rather cold, blustery, showery day with some sunshine; once again there was hail, isolated thunder and snow on northern hills. There were also falls of light snow as far S as Yeovilton and Cork. Reported snow depths during the early morning included 3 cm at Tulloch Bridge, 0.5 cm at Cork Airport and 1 cm at Spadeadam. (St James Park 11.3C, Lake Vyrnwy 4.3C maximum, Aboyne -4.1C minimum, Blencathra 28.8 mm, Tiree 8.4 h.)

On the 14th, after a bright start in the south - and a few hours of sunshine east of the Greenwich Meridian - rain spread SE'wards across Ireland and Cent and S districts of the UK. Most of Scotland just had a few showers. Temperatures were near or rather below normal, and it was quite breezy a result of low pressure centred close to Shetland, 982 mb at 0600 GMT. (Cardiff Bute Park 12.5C, Salsburgh 5.0C maximum, Aboyne 0.4C minimum, Capel Curig 27.0 mm, Weybourne 7.5 h.)

On the 15th most places had some sunshine, but there was generally a lot of cloud with some patchy light rain or drizzle, especially at first in the south, whilst more persistent, mostly light, rain spread across Ireland and Scotland during the afternoon and evening. Temperatures were mostly well up for the time of year. Displays of the Aurora Borealis were visible from parts of Scotland overnight. They were seen from the Highlands and Moray. The displays were also powerful enough to be spotted further south than usual, including from North Berwick in East Lothian. (Roches Point 15.7C, Lerwick 6.2C maximum, Drumnadrochit -0.1C minimum, Winchcombe Sudeley Castle 12.6 mm, Weybourne 9.6 h.)

High pressure developed across the British Isles on the 16th, centred close to Belmullet at 1800 GMT, 1038 mb. Patchy, mostly light, rain moved southeast across the country overnight and at first. Variable cloud cover followed with some sunshine and above normal temperatures; some of the sunnier areas with good shelter to the northwest became warm. (Pershore 17.9C, Baltasound 8.3C maximum, Baltasound -2.8C minimum, Loch Glascarnoch 14.6 mm, Tiree 10.2h.)

High pressure remained centred, at about 1040 mb, close to the SW of Ireland during the 17th. An area of mostly light rain moved SSW across E, SE and Cent S England, where it was rather chilly. It was dry with sunny spells elsewhere, and after some overnight frost many places became quite warm. (Milford Haven and Plymouth 15.4C, Baltasound 7.1C maximum, Katesbridge -2.3C minimum, Lerwick 2.8 mm, Camborne 7.9 h.)

Pressure remained high across the British Isles on the 18th, due to a large centre to the W of Ireland. SE England was dull and rather chilly with spells of mostly light rain. Most other districts had some sunshine and it became warm in places; the best of the sunshine was over E and S Scotland where it was locally unseasonably warm. In parts of East Anglia the daytime temperature failed to reach 8C. (Edinburgh Botanic Gardens 19.0C, Cromer 6.4C maximum, Yeovilton -2.4C minimum, Weybourne 4.4 mm, Kinloss 9.9 h.)

On the 19th it was the turn of the SE corner of the UK to have sunshine, whilst many other areas were fairly cloudy with a patch of two of drizzle. Many places were quite chilly, but there were again some very warm, sunny spots over the S half of Scotland. (Tyndrum 17.4C, Fylingdales 6.0C maximum, Braemar -2.2C minimum, Wainfleet 2.8 mm, Shoeburyness 11.1 h.)

The winds turned NW'ly in most areas on the 20th. Many places were grey and rather chilly, but there were sunnier and locally very warm spots, especially over parts of N England and E Scotland - before patchy drizzle moved south over E Scotland late in the day. At Aboyne there was a diurnal temperature range of 20.9 degC. (Aboyne 17.6C, Okehampton 7.2C maximum, Aboyne -3.3C minimum, Baltasound 4.0 mm, Charterhall 10.5 h.)

Pressure remained high on the 21st, but many districts were fairly cloudy, but it was sunny over parts of S Scotland, N England and Wales. Temperatures were mostly not far from normal after an early air frost in parts of Cent, E and s Scotland. (Usk No.2 14.2C, Fair Isle 7.1C maximum, Braemar -3.9C minimum, Lerwick 1.2 mm, Glasgow 11.1 h.)

High pressure (centred close to the Channel Islands, 1029 mb, at 1200 GMT) continued to dominate the weather on the 22nd. Many inland areas of England, Wales and E Scotland had an air frost at first while in W Ireland minimum temperatures remained above 7C. Precipitation was generally confined to the Northern Isles; England, E Wales and E Scotland had a day with sunny spells, elsewhere it was mostly dull. The warmest conditions were to be found in the London area and in parts of E Yorkshire. (St James Park 15.0C, Spadeadam 7.2C maximum, Aboyne -5.1C minimum, Lerwick 2.0 mm, St Athan 10.8 h.)

Pressure fell on the 23rd, introducing a W'ly flow and allowing a cold front to spread rain across Ireland and Scotland later in the day. There was a misty start to the day in the SE corner of England with a slight air frost in places here. Rainfall amounts were mostly slight and the best of any sunshine was to be found SE of a line Hull-Cardiff and across N and Cent areas of Scotland. (Hereford 14.0C, Eskdalemuir 7.0C maximum, Santon Downham -3.2C minimum, Achnagart 6.6 mm, Jersey Airport 11.0 h.)

Slow-moving fronts gave areas of rain on the 24th, which moved SE'wards and tended to die out across England. Most places, except in parts of E Scotland and to the S of London, were free of overnight air frost while most areas saw spells of sunshine at times during the day. It was a mild day across most Cent areas of England. (Usk No.2 15.1C, Dalwhinnie 6.9C maximum, Kinbrace -1.0C minimum, Dunstaffnage 19.0 mm, Valley 9.6 h.)

Air frost at low levels on the 25th was confined to parts of Cent S England, but most places away from areas of E and NE England saw some rain (mainly light) as weak fronts moved SE'wards across the British Isles. The best of the sunshine was mainly confined to areas of E Scotland and to England and Wales (south of a line Liverpool-Hull). It was a mild day in the E half of England. (Hull East Park 15.3C, Eskdalemuir 7.0C maximum, Hurn -1.8C minimum, Capel Curig 20.0 mm, Manston 9.0 h.)

The 26th dawned after a mild night across England and wales, although it was cooler across Scotland and Ireland behind a cold front that gave overnight rain in these areas. The frontal rain continued to push E'wards during the day, with showers following the rain. Later in the day these showers turned wintry in parts of Ireland, Scotland and N England. (Cavendish 13.9C, Dalwhinnie 4.4C maximum, Lough Fea 0.9C minimum, Achnagart 35.6 mm, Aberdaron 7.8 h.)

Afyer some overnight showers into the 27th, and frost in the clearer areas, most places were bright or sunny for a time, but it clouded over from the west and rain spread to many western and northern districts during the afternoon and evening. Temperatures were near or rather below normal, and it was breezy due to a deep depression SW of Iceland. (Kew Gardens 12.7C, Dalwhinnie 5.3C maximum, Kinbrace -5.6C minimum, Tyndrum 15.6 mm, Boulmer 7.7 h.)

The 28th was predominantly wet over much of the W and N of the British Isles, although N and E areas of Scotland were drier and brighter for a few hours during the day. There was copious rainfall over Snowdonia and the Lake District hills. Southern Britain was mostly dry and cloudy. Temperatures were near or above normal, and it was windy. (Normanby Hall 16.2C, Lerwick 8.3C maximum, Dalwhinnie 2.3C minimum, Shap 109.4 mm, Lerwick 6.2 h.)

On the 29th rain in the northwest slowly retreated as sunny, warm (away from windward coasts) weather spread steadily from the southeast. However, it was the turn of the Western Highlands to catch copious rainfall. Maximum temperatures widely reached 17-19C across many E areas of England, away from the extreme SE. (Writtle 20.4C, St Bees Head 9.0C maximum, Okehampton 6.4C minimum, Achnagart 81.6 mm, Jersey Airport 12.2 h.)

On the 30th NW Scotland was very wet. Elsewhere, it was increasingly sunny SE'wards, and, especially in SE England, there was a very marked daily temperature range (of 22-24 degC) between some slight overnight frost and an unseasonably warm afternoon for many. According to the Met Office, the day saw the second highest March temperature on record, just behind 25.6C at Mepal, Cambridgeshire, in 1968. (Kew Gardens 24.5C, Lerwick 7.9C maximum, Santon Downham -1.7C minimum, Achnagart 73.4 mm, Shoeburyness 12.1 h.)

After a wet night in the northwest into the 31st, patchy rain and cold air edged S'wards across Scotland and N and W areas of Ireland. It was still warm or very warm over much of England and Wales, away from most S and W coasts - a few of which, especially in the southwest, were foggy. It was fairly cloudy in the south with the odd patch of light rain, but quite sunny elsewhere. Parts of the Midlands and E England were unseasonably warm. (Weybourne 23.9C, Lentran 4.4C maximum, Eskdalemuir -0.2C minimum, Lentran 26.6 mm, Ronaldsway 10.2 h.)

British Isles weather, April 2021

Despite an E'ly flow on the 1st, early air frost was mainly confined to NE Scotland. It was sunny over much of Scotland and Northern Ireland. Much of England and Wales was fairly cloudy, and there was the occasional light shower in the SW; there was some sunshine, especially in the S. It was generally colder during the day, but was still quite warm, although breezy, in much of the S and SW. (Jersey Airport 22.0C, Lake Vyrnwy 5.8C maximum, Loch Glascarnoch -3.0C minimum, Dunkeswell 1.4 mm, Loch Glascarnoch 12.2 h.)

High pressure centred to the W of Scotland on the 2nd led to a manly dry day across the British Isles. It was a very frosty night in many N districts. Much of E and Cent Britain (especially England) had a grey, chilly day, but many S and W areas were sunny with temperatures approaching, or even exceeding, normal. It was breezy in the S. (Valentia 16.6C, Baltasound 6.8C maximum, Tulloch Bridge -6.1C minimum, Kielder Castle 0.2 mm, Thomastown 12.5 h.)

Pressure remained high on the 3rd. SE Britain was mostly grey and chilly, though it did brighten a little in the afternoon. Most other districts were sunny, with temperatures mostly rising well up to normal, after some overnight frost across Scotland and in parts of Wales and E Ireland. Parts of Ireland, S and E Scotland became warm. (Drumnadrochit 17.6C, Fylingdales 6.1C maximum, Tulloch Bridge -5.8C minimum, Newton Rigg 0.2 mm, Glasgow 12.5 h.)

On the 4th, after overnight frost, many places were quite sunny, and away from windward coasts it became fairly warm, especially over Cent and E England. Cloudy weather with freshening winds spread across Scotland and Northern Ireland, where it became colder with outbreaks of rain. N Scotland was much colder in the evening with some snow: at 8 p.m., Kirkwall had a temperature of 0C with a wind of 31 kn gusting to 48 kn. (Pershore 17.9C, Fair Isle 7.4C maximum, Benson -5.2C minimum, Cassley 14.0 mm, Shobdon 12.2 h.)

Very cold weather spread to all areas by early afternoon on the 5th. The dawn period saw a widespread severe frost over N Scotland, with temperatures of -2C to -5C and 20 kn winds. There were a lot of showers, mostly of snow, over northern regions, and some snow flurries elsewhere on the leading edge of the cold air. However, many places with good shelter to the N became sunny. Snow was reported as far S as Dublin and the Midlands at times during the day, with depths across N Scotland including 5 cm at Lerwick and Loch Glascarnoch and 7 cm at Kirkwall. (St Helier 11.9C, Loch Glascarnoch 1.0C maximum, Aviemore -5.4C minimum, Kinlochewe 8.4 mm, Glasgow 12.5 h.)

After a widespread air frost (only coastal areas, and the extreme SW of England and Ireland were exempt), the 6th was very cold with some sunshine and widespread hail and snow showers, some of them heavy especially in the north. Snow fell as far S as the Channel Islands, with reported depths during the day including 5 cm at Capel Curig, 3 cm at Lough Fea and 11 cm at Loch Glascarnoch. (Pershore 9.8C, Braemar 0.6C maximum, Eskdalemuir -4.2C minimum, Kinlochewe 12.0 mm, Prestwick 10.7 h.)

The 7th, after a widespread sharp air frost, mainly stayed very cold; many places were sunny for a time, but it turned cloudier from the NW during the day. There were wintry showers in the N and W at first and a few patches of light rain and snow accompanied the frontal cloud which was associated with a warm front. The best of the sunshine was to be found in N Scotland and in E areas of the UK. (Shannon Airport 11.7C, Loch Glascarnoch 1.6C maximum, Benson -7.5C minimum, Scolton Country Park 4.0 mm, Wattisham 8.7 h.)

On the 8th, rain moved slowly SE'wards across N and Cent regions; rather brighter, showery weather followed over N Scotland where some snow fell in places. There was a little rain in S Britain, on a generally cloudy day, although there were brighter areas. It was still mostly quite cold, but temperatures were higher than of late, especially in E England. (Holbeach 14.2C, Loch Glascarnoch 5.8C maximum, Fyvie Castle -2.4C minimum, Achnagart 46.8 mm, Jersey Airport 12.0 h.)

Fronts moved slowly SE'wards on the 9th; associated rain areas moved very slowly SE'wards, affecting much of Wales, the Midlands and N parts of East Anglia for much of the day, although the rain was mostly light and eased from the W. Most of S Britain was dry with some sunshine. Northern regions behind the fronts were brighter, after overnight frost, but there were wintry showers; S Scotland was sunny. It was mostly cold, in many places very cold over Cent and N districts, but temperatures were not far from normal in the S. Reported snow depths included 5 cm at Loch Glascarnoch. (Writtle 14.7C, Loch Glascarnoch 1.5C maximum, Kinbrace -3.7C minimum, Kinlochewe 8.0 mm, Glasgow 13.0 h.)

Pressure remained high to the W of the British Isles on the 10th. There was a widespread moderate to severe frost at first over much of Ireland, Wales, the W Midlands, N England and Scotland. SE England was cloudy with some mostly light rain. Elsewhere, it was showery during the day; some of the showers were heavy with hail, as well as snow especially in the N. Loch Glascarnoch reported a snow depth of 10 cm for a while. Many places away from the Midlands, East Anglia and SE England were quite sunny. With a few exceptions in well-sheltered districts, it was cold or very cold. (Plymouth 13.6C, Loch Glascarnoch 3.5C maximum, Shap -7.8C minimum, Almondsbury 7.4 mm, Aberdaron 12.9 h.)

High pressure built from the W during the 11th. There was a widespread frost overnight over almost all the British Isles away from coastal areas; it was severe in some N districts. Most places then had another cold or very cold day with a fair amount of sunshine, but also showers, often of snow. There were three sferics in north Cambridgeshire around dusk. Heavy snowfall over parts of Teesside and North Yorkshire caused disruption for motorists. The A169 White Way Heads in the North York Moors was closed to traffic due to heavy snow, as was the A174 Apple Orchard Bank near Skelton after a lorry got stuck in icy conditions. Elsewhere, snow depths of 4 cm were reported from Leek and Loch Glascarnoch. (Plymouth 11.2C, Loch Glascarnoch 3.9C maximum, Tulloch Bridge -8.7C minimum, Rochdale 6.0 mm, Cork Airport 12.2 h.)

Most of England, E Wales, Scotland and N Ireland had an air frost in to the 12th, with a severe frost in many N districts. Wintry showers continued near many E coasts, whilst a warm-front wave brought an area of mostly snow SE'wards across Wales and S Britain, giving many places a covering for a time. A fairly sunny, cold day followed over most of the country with a few more wintry showers, but it stayed cloudy over parts of Ireland with patchy rain. Scotland recorded its coldest April night in eight years as temperatures at Tulloch Bridge fell to -9.4C overnight, while at 0300 GMT the snow depth at Lake Vrynwy was 7 cm. At 0900 GMT the snow depth in Reading was 4 cm. (Plymouth 12.5C, Loch Glascarnoch 6.1C maximum, Tulloch Bridge -9.4C minimum, Castlederg 12.6 mm, Stornoway 13.1 h.)

W coastal areas and the S half of Ireland were mostly frost-free into the 13th; elsewhere air first was widespread. During the day it became generally less cold; despite the prevailing high pressure a weak warm front pushed E'wards over N areas before fading. Much cloud developed as shallow instability was released by the rising temperatures under morning sunshine. There were showers in various districts, with rather more persistent frontal rain over parts of S Scotland. (Astwood Bank 14.6C, Fair Isle 6.3C maximum, Braemar -8.0C minimum, Salsburgh 11.2 mm, Kinloss 13.3 h.)

Pressure remained high on the 14th; central pressure was 1035 mb at 1200 GMT over W Scotland. Many inland areas away from SW parts of the British Isles had an early air frost but sunny weather then followed. There were a few showers in SW England while temperatures rose well up to normal in some W districts, especially across most of Ireland. (Castlederg 15.3C, Fylingdales 7.6C maximum, Braemar -6.0C minimum, Cardinham 1.6 mm, Aberdaron 13.2 h.)

Into the 15th overnight frost was widespread and locally quite sharp. Much of the British Isles was then fairly sunny, but East Anglia and the extreme SE became cloudier with some showers. It was mostly quite cold, especially in the SE, but parts of Scotland and Ireland became rather warm. (Glasgow 15.9C, Wych Cross 7.7C maximum, Aboyne -6.3C minimum, Cromer 1.8 mm, Kinloss 13.6 h.)

Away from most of Ireland and coastal areas of the UK, there was a widespread air frost into the 16th. Most areas had a sunny day although a front led to some cloudier skies across W areas of Scotland and Ireland. There were showers around the Wash in the morning, and some rain later in the Outer Hebrides and W Ireland. It was mostly quite chilly, except in some N districts. 4 mm of rain fell at Belmullet in the 12 hours ending 1800 GMT. (Aboyne 14.9C, Fair Isle 8.1C maximum, Aboyne -7.3C minimum, Wittering 1.6 mm, Dundrennan 13.1 h.)

Pressure remained high over the British Isles on the 17th and an inland air frost was again widespread, away from Ireland and W Scotland. A very sunny day ensued, away from W and Cent Ireland and N Scotland, where it was cloudier. There was some frontal rain over the extreme W of Ireland; Valentia reported 4 mm falling in the 12 hours ending 1800 GMT. (Preston Moor Park 15.5C, Lerwick 8.3C maximum, Sennybridge -5.6C minimum, Wiggonholt 0.2 mm, Hurn, Lyneham and Shobdon 13.1 h.)

Into the 18th overnight frost was less widespread than on recent nights, affecting more especially areas in the Midlands and towards the E of England. There was mostly quite a lot of cloud across Ireland and Scotland with some rain in W Scotland and over W and N Ireland. The rain edged a little E'wards across N Britain and Ireland during the day, but slowly petered out. The SE was mostly sunny and became rather warmer than of late. (St James Park 16.0C, Killylane 8.3C maximum, Woburn -4.2C minimum, Castlederg 8.8 mm, Shoeburyness, Weybourne and Waddington 12.9 h.)

There was an overnight frost into the 19th, and a few fog patches, over England and Wales, and in S and E Scotland, followed by a mostly sunny day. It was cloudier in W and NW Scotland and over Ireland, and patchy rain moved into W and N Scotland and across Ireland. Afternoon temperatures were mostly well up to normal; many sheltered localities became rather warm. (Northolt 18.3C, Weybourne 7.9C maximum, South Newington -4.1C minimum, Stornoway 10.0 mm, Jersey Airport and Rostherne 13.1 h.)

On the 20th there was some frost and a few fog patches over Cent and S districts at first, whilst W and N areas had some rain. A few patches of rain came rather further SE'wards during the day, but most of England and Wales was dry with some sunshine, especially in the S. It also brightened up over W and N Scotland and in parts of W Ireland, although with a few showers. It was mostly rather colder than of late over Ireland and Scotland, but many inland districts of England were quite warm. (Heathrow and Pershore 18.6C, Fair Isle 8.7C maximum, Hurn -1.7C minimum, Aultbea 7.8 mm, Jersey Airport 12.5 h.)

High pressure on the 21st, centred at 1026 mb close to Stornoway at 1200 GMT, led to a mainly dry day. N and Cent Scotland had an air frost at first with frontal cloud further S giving some light rain in S Scotland and N England that slowly moved S'wards, petering out as it did so. After some fog patches in S areas, it was a sunny day across Scotland and in areas of Ireland, but skies were cloudier elsewhere. (Bude 17.7C, Fair Isle 7.7C maximum, Tulloch Bridge -6.3C minimum, Charterhall 0.8 mm, Tiree 13.9 h.)

High pressure centred over E England on the b>22nd led to another mostly dry day. Much of England (away from the SW), E Wales and Scotland had an air frost at first. The day was very sunny across most of the British Isles, N and Cent areas of Scotland being an exception due to cloudier skies here at times that gave some light rainfall over Shetland. (Drumnadrochit 17.9C, Wick Airport 8.8C maximum, Kinbrace -6.3C minimum, Lerwick 1.4 mm, Ronaldsway 13.8 h.)

High pressure persisted on the 23rd with another air frost in many E and Cent areas of the UK. A dry and very sunny day followed in all areas, with W regions seeing the highest temperatures although there were cloudier skies across W Ireland. A fair amount of high cloud did spread SE'wards across the UK during the day (Porthmadog 20.8C, Wick Airport 9.7C maximum, Santon Downham -4.7C minimum, Wiggonholt 0.2 mm, Aberdaron and Guernsey Airport 13.8 h.)

As the high pressure centre migrated towards Shetland on the 24th, a SE'ly flow became established in most areas. There was a slight air frost in a few places, notably in E and Cent Scotland, while at Valentia the overnight minimum temperature was 12.5C. There was some light rain over Shetland; elsewhere it was generally very sunny although onshore-blowing cloud affected some coastal parts of E England. It was warmest in W areas of the British Isles with maximum temperatures close to the North Sea being around 10C. (Valentia 20.1C, Lerwick 7.3C maximum, Kinbrace -4.9C minimum, Baltasound 2.2 mm, Kinloss 13.9 h.)

Into the 25th there was an air frost in parts of NE England, E and N Scotland in East Anglia and E England. It was a warm day in some W areas of Scotland and Ireland, but rather cool in places elsewhere, despite it being a dry day. (Belmullet 19.5C, Fair Isle 8.7C maximum, Altnaharra -4.2C minimum, Several places trace, Cork Airport and Shannon Airport 13.8 h.)

An area of low pressure close to N Scotland on the 26th pushed rain SE'wards across N Scotland before dawn, and this then spread SE'wards across Scotland and into N England by the end of the day. There were pockets of air frost in parts of S Scotland, Wales, Ireland and England with a sunny day following across Wales and in S and Cent parts of England and Ireland. Except in parts of Ireland and Wales it was a generally cool day. (Armagh 17.5C, Fair Isle 7.2C maximum, Topcliffe -3.6C minimum, Fyvie Castle 8.8 mm, Cork Airport and Shannon Airport 13.7 h.)

The low centre slipped slowly S during the 27th - centre 1006 mb near Bristol at 1800 GMT. Areas of rain and showers spread S'wards during the day, being most extensive in parts of Cent and NE England. Ahead of the rain and cloud there were sunny spells across S districts, and it remained sunny throughout the day in parts of Essex, Kent and the Channel Islands. Further N it was a dull day. There was an early air frost in parts of East Anglia and SE England; it was then a cool day away from some sunny areas around London with temperatures across Scotland remaining below 10C in many areas. (Wisley 18.6C, Braemar 5.2C maximum, Santon Downham -2.8C minimum, Leek 9.6 mm, Jersey Airport 13.0 h.)

The 28th brought the first measurable rainfall of the month to parts of S England, earlier measurable falls having been only of snow. There was little air frost overnight, as cloudy skies brought frontal rain to most of the UK, with the exception of parts of SE England and East Anglia. Across Scotland and Ireland the day was mainly showery; much of E England remained until sunset while the rain further W across England and Wales slowly moved SE'wards reaching the dry areas of East Anglia and SE England in the evening. The best of the sunshine was to be found across Norfolk while much of Cent and W England remained dull. Some sferics were reported over S Dorset around dawn and at times in the afternoon. (Santon Downham 15.0C, Braemar 6.8C maximum, Altnaharra -3.6C minimum, St Athan 30.0 mm, Weybourne 11.4 h.)

A N'ly flow led to the widespread spreading of showers across the British Isles on the 29th; some of the showers over N Scotland were wintry. Sheltered areas as far S as S England and Dublin had an overnight air frost. It was particularly sunny in some W areas of Wales and Scotland and most other regions had sunny spells in between any showers. Many areas of S England remained dry while daytime temperatures were below normal in all areas; it was especially cool close to the North Sea coastline. (Usk No. 2 13.5C, Fylingdales 6.8C maximum, Kinbrace -4.5C minimum, Thomastown 6.4 mm, Aberdaron 12.6 h.)

Many areas across the UK had a slight air frost before dawn on the 30th. Widespread showers across the British Isles were slow-moving, and locally heavy; there was some very isolated thunder in S England. Up to 2.5 cm of snow fell during the morning in and around Clee Hill and Church Stretton in Shropshire. (Cardinham 13.7C, Balmoral 7.1C maximum, Tulloch Bridge -4.2C minimum, Gringley on the Hill 19.0 mm, Tiree 14.2 h.)

British Isles weather, May 2021

High pressure and light winds not the 1st led to a widespread air frost in many inland areas of the British Isles. A mostly cold day followed with sunny spells and a fair number of showers, some heavy with hail - and snow on northern hills. (Gosport Fleetlands 15.0C, Balmoral 7.1C maximum, Shap -5.8C minimum, Wainfleet 8.6 mm, Manston 13.0 h.)

The 2nd dawned after a widespread inland air frost in many areas. During the day widespread showers developed, these being wintry in some N areas of Scotland. The best of the sunshine was across SW, Cent S England and the Channel Islands with cloudier skies further N and W. In many areas it was a little warmer than on the preceding day. (Pershore 16.4C, Lerwick 7.0C maximum, Tyndrum -4.2C minimum, Goudhurst 8.0 mm, Jersey Airport 13.1 h.)

There was an air frost into the 3rd in some inland areas of Scotland and N England. Low pressure close to and later over Ireland (centred over Cent Ireland at 1800 GMT, 986 mb) pushed wet and increasingly windy weather across most areas although the extreme N of Scotland and SE England had some sunshine at first. Blustery showers followed over Ireland, S Scotland, Wales and, eventually, much of England (with thunder briefly over north Cheshire in the early evening). Mumbles recorded a gust of 74 mph. It was a cold day for most, with a few reports of snow in the north. Homes were left without power and travel was disrupted as the winds hit Wales. Flooding closed some roads while strong winds shut the M48 Severn Bridge and meant restrictions on the A55's Britannia Bridge. In Connah's Quay, the A548 Flintshire Bridge is closed in both directions due to strong winds. Train services were disrupted on the Conwy Valley Line between Blaenau Ffestiniog and Llandudno because of flooding, with rail replacement services put in place. Trains were also delayed on routes from Cardiff to Pontypridd, Swansea to Shrewsbury, Barry to Bridgend and Pontypridd to Treherbert. (St Helier 15.2C, Tyndrum 5.0C maximum, Kinbrace -5.9C minimum, Capel Curig 50.8 mm, Jersey Airport 8.5 h.)

The 4th dawned after the first frost-free night countrywide (at low levels) since 29 March but much of the country had a cold or very cold day, especially near a band of rain which drifted slowly S'wards from W and S Scotland into NW England across to northern parts of East Anglia. Either side of this it was a little brighter and showery with the best of the sunshine in W Ireland. There was isolated thunder, with some snow in the north - and a heavy hailstorm hit the centre of Manchester in the evening. However, it was quite sunny and only rather cold over much of S England. Strong winds eased slowly as the low centred crossed the UK and headed over the North Sea. (Shoreham 15.4C, Blencathra 5.7C maximum, Dalwhinnie 0.7C minimum, Blencathra 33.0 mm, Shannon Airport 12.7 h.)

Sheltered areas of Cent Scotland and N England, in particular, had a slight air first into the 5th. A N'ly flow resulted in a mainly showery and quite cold day, with some snow in Scotland, N England and N Ireland. Some places had hail, and there was also a fair amount of thunder. There were also sunny spells, especially in NW England and SW Scotland. Snow was lying on the Glenshane Pass early in the day was clearly visible on the hills around Londonderry. (Heathrow 14.4C, Loch Glascarnoch 6.2C maximum, Warcop -3.1C minimum, Swyddffynnon 12.6 mm, Morecambe 14.1 h.)

There was a fairly widespread frost overnight into the 6th, away from the coasts and N Scotland, whilst showers continued in various districts with some longer outbreaks of rain or snow in N Scotland; 5 cm of lying snow was reported near Inverness in the early morning. Another showery, cold day followed, especially in the E and N; there was local thunder in the afternoon, notably over North Yorkshire, Lincolnshire and north Norfolk. The best of the sunshine, and the fewest showers, was in S England, and across Ireland and W Wales, after a wet start to the day in Cornwall and the Channel Islands. Snowfall has brought disruption to parts of Scotland, with the Highlands under a thick blanket of snow at dawn. The A939 near Tomintoul in Moray was closed because a tanker was stuck in snow. Bear Scotland North West said it had seven gritters on the A9 between Drumochter and Inverness working to keep the road clear. A power cut affected the polling station at Gergask Primary School in Laggan, but Highland Council said the electricity supply was restored at 1000 a.m. (Plymouth 14.3C, Dalwhinnie 5.6C maximum, Eskdalemuir -5.5C minimum, Altnaharra 32.0 mm, Aberdaron 13.5 h.)

There was patchy air frost in inland areas, particularly Cent Ireland, into the 7th and a developing ridge then led to a day with sunny spells in most areas. There were further showery outbreaks in the N and E of the UK, with isolated thunder on the North Yorkshire Moors in the afternoon. Rain moved into S Ireland, SW England and the Channel Islands in the evening. It was a mostly rather cold day. (Heathrow 15.7C, Dalwhinnie 7.4C maximum, Topcliffe -4.4C minimum, Scarborough 9.6 mm, Morecambe 12.8 h.)

After an early air frost in parts of Scotland and N England into the 8th, most places had a few hours of wet and windy weather as rain spread from the SW overnight. Apart from a shower or two, Shetland stayed dry, and many other districts (except for the SW areas, Wales and N Scotland), became drier late in the day. It was cold in the north, and mostly rather cool elsewhere - but the extreme SE of England, the Channel Islands and parts of Ireland became warmer. (Jersey Airport 18.9C, Dalwhinnie 5.9C maximum, Tulloch Bridge -4.2C minimum, Libanus 52.2 mm, Jersey Airport 10.1 h.)

Low pressure to the W of Ireland during the 9th (MSL pressure down to 979.4 mb at Belmullet at 1800 GMT) led to flow from the S and an unsettled day in W areas. There was some sunshine, but it was fairly cloudy with showery outbreaks but many places, especially towards the SE, were dry. However, thundery outbreaks affected Kent and Sussex in the morning and evening and areas of NW Ireland in the afternoon. Temperatures were higher than of late, and parts of E England were warm. (Santon Downham 22.5C, Fair Isle 7.7C maximum Tain Range -0.1C minimum, South Uist 19.0 mm, Weybourne 8.0 h.)

A low pressure centre persisted close to W Ireland during the 10th. Rain moved NE'wards over the most SE'ly and E'ly regions of England overnight, and there were some showers elsewhere. The day soon became very showery, but the showers cleared N'wards away from SE counties during the afternoon to leave sunny, breezy weather. Elsewhere, some of the showers became heavy and, especially over N England, thundery, while more persistent rain moved NW'wards into the Northern Isles. Temperatures were mostly not far from normal. (Cromer 17.9C, Lerwick 8.0C maximum, Tain Range 3.2C minimum, Fair Isle 13.8 mm, Shoeburyness 9.8 h.)

On the 11th rain slowly cleared from northernmost Scotland, and much of Scotland and Northern Ireland was dry with sunny spells until showers moved into southern Scotland late in the day. Bands of showers moved north over England and Wales, with thunder in the afternoon away from the more SE'ly regions, where it again became mostly sunny and breezy. Some of the brighter areas were quite warm, but colder air moved in from the SW under a cold pool during the afternoon and evening - and thundery activity continued under it into the late evening over the north Midlands. A 9 year-old boy was killed by lightning at Blackpool shortly before 5pm. (St James Park 18.2C, Baltasound 8.9C maximum, Shobdon 1.7C minimum, Eskdalemuir 20.2 mm, Katesbridge 13.5 h.)

Pressure remained low across the British Isles on the 12th. Overnight, heavy and thundery showers drifted across the Pennines and out into the North Sea off the England/Scotland border. There were a few showers elsewhere, and a band of quite heavy rain drifted N'wards over Cent Scotland - and slowly away into N Scotland during the day. Further showers transferred northwards during the day, though there were fewer of them, with only isolated thunder in central regions. The more SE'ly areas again became sunny. However, a longer spell of rain affected much of Wales for a few hours at first, and another moved very slowly northeast across SW districts during the day. It was also a wet day across much of Ireland. The wetter areas were cold; elsewhere, temperatures were mostly not far from normal. (Santon Downham 17.9C, Inverbervie 7.9C maximum, Katesbridge -1.0C minimum, Aboyne 24.0 mm, Ronaldsway 12.1 h.)

Low pressure remained slow-moving over the English Channel on the 13th. Rain edged away slowly from N Scotland early in the day. Most N and Cent districts were then rather showery, whilst bands of rain moved slowly N, then NW, across Wales and S Britain. There were brighter areas (notably parts of S Ireland and Cornwall) where it was locally on the warm side, but most places were chilly. There was isolated thunder, especially over the Midlands. (Ballywatticock 17.2C, Okehampton 8.2C maximum, Katesbridge -2.2C minimum, Liscombe 41.2 mm, Cork Airport 12.2 h.)

Ob the 14th, after some overnight rain, much of the British Isles had a dry, cold and cloudy day. There were some brighter, warmer areas, especially in the west - which in turn led to some heavy showers breaking out, with thunder over N Ireland. Frontal rain spread into the S Ireland and SW areas of the UK later in the day. (Trawsgoed 16.6C, Fylingdales 7.6C maximum, Katesbridge -1.6C minimum, Swyddffynnon 19.2 mm, Tiree 7.9 h.)

Into the 15th, rain moved NE'wards across S and Cent areas of the British Isles, but became lighter and patchy in its journey. Scotland just had a few showers, and it turned a little brighter over England and Wales, although with a lot of showers - some of them very heavy with localised hail and thunder. It was chilly, and occasionally squally near the showers. (Achnagart 16.5C, Fair Isle 8.5C maximum, Loch Glascarnoch 0.2C minimum, Swyddffynnon 25.8 mm, Stornoway 12.6 h.)

The 16th was generally chilly and showery, with some thunder over Wales and N England - whilst longer outbreaks of rain affected parts of the south. There was some sunshine, and it was locally on the warm side in those areas that missed, or had the fewest, showers. A couple living in a bungalow were forced to flee their home following a lightning strike that caused a fire; the roof collapsed as a result of the blaze and Lyn and Trevor Ellis, from Kidderminster, Worcestershire, lost all possessions. (Myerscough 18.1C, Stornoway 10.2C maximum, Aboyne -0.7C minimum, Okehampton 31.6 mm, Tiree 12.8 h.)

The 17th was showery, with some sunshine. The showers tended to transfer from W to E districts during the day; quite a few of them were heavy, and there was hail and thunder - the latter especially over N Pennine regions around the middle of the day, and the S Midlands, Cent S England and the London area during the afternoon and early evening. It was mostly rather cool. (Pershore College 18.0c, Lerwick 10.1C maximum, Katesbridge -0.9C minimum, Wych Cross 16.4 mm, St Athan 11.2 h.)

The 18th was another showery day with hail, and thunder in places (especially in the E and SE of the UK), but also some sunshine. Pressure remained low just to the W of Ireland. Temperatures were mostly not far from normal but fell sharply in the showers, some of which were accompanied by squally winds. (Hull East Park 17.9C, Fair Isle 9.8C maximum, Katesbridge -1.1C minimum, Coleshill 22.0 mm, Morecambe 13.3 h.)

On the 19th, after overnight rain in the S, it was again a tale of sunshine and showers, with temperatures mostly not far from normal. There was a fair amount of thunder over Cent and E England. (Heathrow and Pershore 18.3C, Inverbervie 9.1C maximum, Eskdalemuir -1.7C minimum, Aboyne 12.6 mm, Aberdaron 12.5 h.)

On the 20th, rain spread NE'wards across Ireland and then spread from the SW across the UK, although NW Scotland and SE England had very little rainfall. It was chilly and became very windy; there were gusts of up to 70 mph over Wales late in the day. Trees came down in the Cathays area of Cardiff, while a roof was severely damaged in Bridgend. Later in the evening, a surfer had to be rescued by the RNLI at Trearddur Bay in Anglesey. The winds were due to an unusually deep area of low pressure for May, that was centred at 982 mb over W Ireland at 1800 GMT. The best of any sunshine was to be found in E areas of the UK. (Chertsey Abbey Mead 15.3C, Lerwick 7.7C maximum, Ravensworth 0.7C minimum, Capel Curig 44.2 mm, Boulmer 4.2h.)

Low pressure moved slowly across N England during much of the 21st, with a central pressure of 983 mb over Lancashire at 1200 GMT. Consequently, it was generally dull, cold or very cold, and wet and windy. Shetland was dry and generally sunny. (Myerscough 15.4C, Dalwhinnie 6.5C maximum, Baltasound 3.4C minimum, Capel Curig 66.2 mm, Lerwick 10.2 h.)

As the low centre moved away E'wards, the 22nd saw a weak NW'ly flow develop over most areas. After some overnight rain, it was a quieter, fairly cloudy and rather cool day. Brighter intervals developed, in turn leading to a scattering of showers breaking out. (Kew Gardens 15.9C, Braemar 8.5C maximum, Braemar -0.1C minimum, Okehampton 22.0 mm, Prestwick 11.9 h.)

On the 23rd frontal rain spread slowly from the west across Ireland and then across most of the UK by the evening; it was preceded (over Cent and E England) and followed (over W Britain and Ireland) by showers. It was quite windy and chilly - and distinctly cold for late May in the wetter areas. There was an early air frost in sheltered inland areas of Scotland. (Coningsby 15.2C, Lake Vyrnwy 7.9C maximum, Altnaharra -3.2C minimum, Capel Curig 26.6 mm, Lerwick 11.7 h.)

Low pressure over the UK on the 24th gave a day that was mostly cloudy and chilly with showers or longer outbreaks of rain, with some weak thundery activity towards the SE. There were some drier, brighter and warmer spots, especially over N England. (Hull East Park 16.7C, Dalwhinnie 7.2C maximum, Castlederg -0.5C minimum, Dalwhinnie 30.2 mm, Ronaldsway and Thomastown 10.6 h.)

On the 25th, although some places had sunny intervals, it was a mostly cloudy day. An area of rain moved slowly E'wards across S Ireland and then S England, whilst a band of showers drifted S'wards from Scotland into N England with isolated thunder, especially in East Yorkshire. It was generally chilly, especially in the wetter areas. (Pershore 17.1C, Okehampton 10.5C maximum, Castlederg 3.5C maximum, Leconfield 21.2 mm, Katesbridge 12.0 h.)

On the 26th there was some sunshine, the best of it in parts of the S and W of the UK and Ireland, and it was generally somewhat warmer than recently - though it was still mostly on the cool side for late May with a lot of cloud. Showers fell chiefly in the N and E of the UK. (Killowen 18.6C maximum, Fylingdales 9.0C maximum, Machrihanish 1.0C minimum, Drumalbin 10.6 mm, Valley 15.4 h.)

High pressure became centred over S parts of the UK later on the 27th although weak fronts spread across Ireland and (later) some W areas of the UK. The day was mostly sunny, though some areas of cloud developed. Rain edged into the far W late in the day. It was generally on the warm side, especially in the SE of the UK. 14 mm of rain fell in the 12 hours ending 1800 GMT at Roches Point. (Wisley 22.0C, Lerwick 9.4C maximum, Sennybridge -0.5C minimum, Derrylin Cornahoule 4.2 mm, Hurn 14.7 h.)

On the 28th there were large areas of cloud across the British Isles, giving a few patches of mostly light rain (particularly in Ireland and Wales). Temperatures were mostly well up to the seasonal normal, and some places (especially in the E) were sunnier and warm - notably parts of northern Scotland. (Achnagart and St Helier 22.1C, Fair Isle 10.1C maximum, Kinbrace 0.8C minimum, Lough Fea 7.2 mm, Lerwick 15.2 h.)

On the 29th there were sunny spells, but mostly a fair amount of cloud, with a few light showers in the W and N - but increasingly sunny weather spread from the SE across much of England during the afternoon. It was mostly quite warm, except near some coasts (e.g. Aboyne and Aviemore recorded 21.8C but Inverbervie only 9.8C). (Chivenor 22.9C, Fair Isle 9.5C maximum, Balmoral 2.1C minimum, Sennybridge 2.0 mm, Weybourne 15.1 h.)

High pressure was centred close to the E of the British Isles on the 30th. There were again some rather persistent areas of cloud, but most places were quite sunny, and it became fairly warm well away from windward coasts - and very warm in parts of Scotland. There were again some cool areas close to the North Sea due to the low cloud. (Achnagart 24.0C, Fair Isle 8.4C maximum, Altnaharra 1.6C minimum, Ryhill 0.2 mm, Stornoway 15.9 h.)

High pressure to the E on the 31st again led to some onshore cloud in E areas at first but most places had a very sunny day. It was a warm day inland across much of the UK but W Ireland was cooler and cloudier due to an approaching front. The temperature rose to 25.1C in Kinlochewe and 24.8C in Northolt (just in time to prevent 24.5C at Kew Gardens on 30 March being the highest temperature in the UK this spring). (Kinlochewe 25.1C, Fair Isle 8.7C maximum, Shap 2.2C minimum, Manston 0.2 mm, Morecambe 15.8 h.)
