SEVERE WEATHER RISKS OVER THE PERIOD- None
Monday 27th will see the area of high pressure recede south over the Channel allowing a milder SW’ly flow with its associated fronts across all parts. A few clear periods inland overnight in the east giving a few mist patches but becoming mainly cloudy from the west on a strengthening SW’ly wind, in the north west. Some mainly light but locally moderate rain will affect the SW & west by dawn, spreading west across all central & northern parts by noon and reaching the north east by the afternoon, it may become rather persistent in places over upslopes. The south should stay mainly cloudy with patchy drizzle about though dry in the SE. Temperatures by day becoming rather mild for many in western England and Wales, up to 14C in the central south but more generally 11-12C though only 8C over the Highlands
Tuesday 28th looks likely to see a cloudy & rather damp SW’ly flow continue across northern areas but as high pressure pushes back up from the south by day skies may be clear enough for some mist and fog to form in the south & east at first. By day it will be mainly dry for the most part away from the NW and west Wales with sunny periods developing especially in the east but staying mainly rather cloudy with outbreaks of light rain at times in the north and NW. The north east may be a bit drier later on with sunny periods developing here too. In the west & SW there’s likely to be a lot of hill and coastal mist and low cloud as well. Temperatures reaching a very mild 15-16C in some central and eastern areas but generally10-12C though more like 9C in parts of Highland Scotland and hills elsewhere.
Wednesday 29th looks set to see the high move away SE allowing a mild S-SW’ly flow across all parts. However it will have enough influence to ensure it stays dry for most parts today. Some early mist and fog patches about inland will slowly clear to give bright or sunny periods for most. Temperatures will generally be a mild 13-15C in many areas but more like10C in the west of Scotland, N Ireland and NW England.
Thursday 1st March looks likely to see high pressure to the south east a little more dominant as pressure rises here but generally a slack SW’ly gradient flow continuing across most parts,slight drizzly rain at times on exposed western coasts and hills almost any where overnight, clearer to the east inland and there will likely be a lot of lowcloud, mist & fog patches at first with a local ground frost inland in afew spots but brighter spells will develop and by the afternoon most inland areas should see some sunshine especially in the lee of hills. Temperatures up to a mild 13-15C in the east & the southeast, more like 10C in the north and NW and only 8C in the Highlands.
Friday 2nd is likely to see high pressure a little more in control for most eastern parts. An early & late slight ground or even air frost is likely in NE England and eastern Scotland with some mist, fog and low cloud patches widespread across the UK, These clearing slowly to give some sunny periods for most but nearer to western &SW‘ern coasts it’ll likely stay rather dull with low cloud, hill fog and drizzle about. Temperatures up to about a mild 13-14Cat best in the south & SE but generally 9-11C & just 5C over the Highlands& N Isles.
As we move into the weekend it’s less certain but on Saturday 3rd & Sunday 4th it looks like we could see anarea of low pressure to the west-northwest then north-northwest start to dominate the UK’s weather, bringing stronger SW’ly winds across all parts as its fronts move in from the Atlantic on Saturday. The north, especially N Ireland& Scotland seeing some rain, heavy on western upslopes at times running across all parts on Saturday, though drier in the east and south east of Scotland but reaching all areas of England and Wales by the afternoon though mainly light. Though initially mild by day in the south with temperatures maxing at about 13-14C for many, becoming a little colder from the north by day, more like 6-8C here. On Sunday the deep low still south of Iceland bringing strong winds to the far NW with gales possible and gusts to 65mph in the most exposed northern & NW’ern spots. Showers at times in the north, blustery at times with a risk of hail. Fronts moving away overnight from the east bringing blustery rain showers to parts of the west & south as well by day though the east & SE may stay dry in the main. Temperatures perhaps up to 12C in the south & 13C in the SW but more like 8-10C elsewhere and over northern high ground more like 5-6C, especiallythe Highlands in the strong to gale force westerly winds
