Staying cold with wintry showers and some bright spells.
Today:
Cloudier than Wednesday with rain spreading into southern counties, perhaps turning to snow over hills, with a few wintry flurries in the north. Cold again with icy stretches first thing. Blustery winds along the south coast. Maximum Temperature 5C.
Tonight:
Wintry showers in the north this evening, sinking southwards overnight mixed with some clearer skies. Remaining cold with a frost and a brisk northwesterly wind. Minimum Temperature -3C.
Outlook for Saturday to Monday:
Wet and windy on Saturday with heavy persistent rain, sleet and some hill snow. Drier overall on Sunday but often cloudy with further rain on Monday. Milder.
UK Outlook for Monday 25 Nov 2024 to Wednesday 4 Dec 2024:
An unsettled start, with strong winds and some showers for many parts, these most frequent in the north. Temperatures easing back towards average for most places, but still mild in the southeast. The strong winds will make it feel rather cold though. It then looks like turning colder for all parts, with a return of wintry showers for a time, especially in the north. Conditions then look like settling down as high pressure briefly builds across the country, this bringing a risk of some stubborn fog patches as winds ease. It may turn unsettled and milder again later next week. Into December, high pressure may re-assert itself, with temperatures generally close to average, but some overnight frost is likely, and rather cold by day where any fog persists.
