Monday could see the coldest night of the winter so far in the UK with some areas forecast to hit temperatures as low as -10C.
Scotland and northern areas of the UK will see what could be the lowest temperatures of the season on Monday night, according to the Met Office.
Snow is forecast for the highlands and high-level areas of northern England, where yellow weather warnings for ice are in place.
Ice is also expected to sweep the rest of the country throughout the day, even reaching the south coast.
Overnight temperatures will range from -10C in sheltered areas of Scotland, to between -1C and -2C in Cornwall and Dorset.
Met Office Meteorologist Simon Partridge said: "There's potential that we could see the coldest night of winter so far on Monday night going into Tuesday morning.
"It depends if we have clear skies over snow for long enough.
"This leads to cold temperatures, and we'll certainly have two cold days.
"Sleet and snow showers are forecast for Monday, which will bring icy patches to low ground and snow to higher ground."
He added a chilly breeze will also add to the wintry climes on Monday and Tuesday, although daytime temperatures will be near the average of around 2C for this time of year.
Luckily, the wintry weather is set to be a "short sharp cold spell" over two days before milder weather moves in on Wednesday.
