British Isles weather, January 2016

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

British Isles weather, February 2016

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

British Isles weather, March 2016

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

British Isles weather, April 2016

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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