Wednesday
A dry and bright day overall, with high pressure centred to the west. Plenty of sunshine and well broken cloud. Showers in northern Scotland, falling as snow over the mountains. A few showers may clip coastal districts in eastern England, perhaps also west & north Wales. A brisk north-westerly breeze across north & eastern regions will make it feel cold. Frosty for some at dawn. Top temperatures 8 or 9C north, 10 to 12C south.

Wednesday night
Dry for most places overnight. Fronts approaching the far north-west bring cloud and some rain to western Scotland, perhaps patches of drizzle developing on western coasts & hills around the Irish Sea. Clear skies across central, southern & eastern Britain - possible shallow mist & fog patches. A frost likely for many away from the far north-west, temperatures widely dipping close to freezing, or just below zero in rural areas.

Thursday
Low pressure to the north-west pushes fronts slowly across northern Britain. Rain on and off much of the day for Scotland & N.Ireland, heaviest over the West Highlands.

Light winds south, a fresh south-westerly north & west. Highs 9 to 12C.

Friday
