Thursday starts on a frosty note across parts of Wales, the far north of England and NE Scotland - where we have seen clear spells overnight. However, cloud cover has kept other areas above freezing, but it's still a chilly start even with the cloud away from the far north and northwest of Scotland - where we have milder air.
Weak weather fronts will bring a cloudy day across east Wales. central, southern and eastern England, with patchy light rain or drizzle. Drier and brighter with some glimpses of sunshine across the far southwest of England, west Wales, NW England and eastern Scotland, northern and western Scotland and Northern Ireland cloudier with patchy light rain. A raw day for many, especially across eastern England, where we will have a cold easterly wind. Temperatures reaching 6C in London, 5C in Cardiff, Manchester and Glasgow, 4C in Newcastle. Mild in the far northwest, with 10C in Stornoway.
A cold front arriving across NW Scotland this evening, bringing a band of more organised rain, will move southeastwards across Scotland, Northern Ireland, northern England and north Wales overnight, followed by clearer and colder conditions behind it. This will mean it will turn frosty across the areas by the end of the night, though we will also see wintry showers arrive across northern Scotland, falling as snow over the hills. Cloudy and frost-free ahead of the front moving southeast across central and southern England.
The cold front will continue to clear SE England by early Friday afternoon, so brightening up here after a dull and damp morning. A sunnier morning, with a frosty start, elsewhere. So many areas having much sunnier day on Friday, but still on the cold side with a brisk northwesterly breeze - which will blow in further wintry showers across northern areas, falling as snow over the hills, giving a covering, and perhaps a few flakes even to lower levels in the heaviest showers. Temperatures reaching 7-8C in the south, 4-6C in the north.
A deep low pressure system moving across Iceland on Saturday will spread a wedge of milder air across the UK from the west during Saturday ahead of an associated frontal system moving southeast off the Atlantic. Much of England and Wales will have a dry and bright day though, but Scotland, Northern Ireland will become increasingly cloudy and milder with outbreaks of rain moving in from the west. Some of this rain working in across NW England by the evening. Temperatures perhaps reaching 6-9C generally, perhaps 10C in the far southwest and northwest of the UK.
A change to back to colder conditions on Sunday, as we see a cold front sweep a band of cloud, rain and milder air southeast off into the near continent by Sunday afternoon, followed by a strong and increasingly cold northwesterly flow, with a peppering of wintry showers returning to the north, falling increasingly as snow over the hills.
Continuing changeable and generally chilly next week. Chilly but bright on Monday, with wintry showers in the north. Turning wet, windy and milder for a time on Tuesday, with a risk of severe gales or stronger in the north - as an intense depression passes to the north of the British Isles. Something we are keeping a close eye on. Colder and clearer conditions returning on Wednesday, but remaining windy with further wintry showers across the north, falling as snow even to lower levels across Scotland.
