Temperatures have stayed firmly below freezing for the 12th night in a row across the UK, as forecasters predict the weather will turn milder into next week.
Scotland remained the coldest place in the UK, with the Met Office reporting a low of -13.9C (7F) in Kinbrace in the northern Scottish Highlands.
Wales experienced a low of -2.2C at Hawarden, Flintshire; England’s coldest temperature was -7.8C at Cavendish, Suffolk; and Northern Ireland recorded -1.5C at Katesbridge, Co Down.
Greater London had temperatures of -6.2C, with it being a slightly warmer -2.6C in the centre of the capital. Edinburgh reached a low of -1.7C, while Cardiff hit a comparatively balmy 3.2C according to the forecaster’s data.
It means that the UK as a whole has not had temperatures go above freezing at night since the year began, and the last time the temperatures were in positive figures was on New Year’s Eve.
Met Office meteorologist Jonathan Vautrey said it would feel considerably warmer in the early stages of next week, caused by southerly winds bringing warmer air.
Met Office meteorologist Greg Dewhurst said that by Monday morning, Northern Ireland and western Scotland could have temperatures of between 9C and 10C. Meanwhile, he added, most places would be between -1C and 3C, which is not as cold compared with recent nights.
Next week is set to start with a north and south split for both the temperatures and wider weather. Northern Ireland and the northern half of the country are forecast to be cloudy with outbreaks of patchy rain and temperatures between 9C and 12C; while the central and southern areas could be drier, with temperatures between 5C and 8C.
Tuesday will be similar, but potentially drier, with temperatures between 11C and 12C in the north and 8C-9C in the south.
A Met Office spokesperson said: “Daytime temperatures for the week ahead will typically be 9C to 12C by day and frost generally limited to central and southern counties of England and Wales at night with minimums around 2C to -2C.”
Vautrey said warmer temperatures could lead to thawing snow and surface water on roads.
Scotland and Northern Ireland are forecast to experience rain on Sunday night into Monday morning.

It came as Friday night had the coldest January overnight temperature since 2010. Altnaharra, a hamlet in the Scottish Highlands, recorded -18.9C.
Shap in Cumbria had reached -11C, and Heathrow registered -5C.
The increased demand on energy supplies caused by the cold snap meant the government was forced to insist the UK has enough gas and electricity stocks to meet demand, after the owner of the country’s largest gas stores said levels had become “concerningly low”.
