Temperature will dip very close to zero this morning as Brits wake to a chilly start to the day, forecasters say.
The Met Office says brisk north-easterly winds will make it a cold day for many.
And BBC meteorologist Ben Rich says temperatures could drop “very close” to 0C in parts of Scotland, while it will be as low as 5C elsewhere in the UK.
Later in the day there will be plenty of sunshine for much of the country, especially the North West, although most areas will be at risk of showers.
The Met Office said: “Many parts will be dry with sunny spells, especially in the west.
“Scattered showers will be affecting eastern and some central areas.
“It will be feeling chilly with a brisk north-easterly wind.”
The UK has been in the grip of a low pressure system, with blustery and showery weather on Tuesday and Wednesday.
But the Met Office says “high pressure to the north should lead to some quieter weather through the end of the week”.
The mild weather as the week progresses is set to be the calm before a 1,000 mile-wide “Norwegian barrage” hits the country.
That front threatens to thrust Britain into an early winter by next month with temperatures as low as -10C in Scotland, according to reports.
Some northwestern areas will stay dry with sunny spells. Elsewhere, some sunny intervals but areas of cloud and a few showers affecting many areas at some stage. Rather breezy away from the north, making it feel on the cool side.
Northern and some western areas seeing clear spells, lighter winds and a touch of frost in places, perhaps the odd fog patch. Elsewhere, rather cloudy with the odd light shower.
Plenty of dry weather with some sunshine, so not feeling too bad with lighter winds. However still some cloudier areas and the odd light shower, these focused in the east.
Outlook for Friday to Sunday
Mostly dry with variable amounts of cloud, sunniest in the southwest and cloudy in the northeast. Rain arriving in far west by Sunday evening. Rather cold with patchy rural frost.
