Britain looks set for a distinctly colder end to January with the possibility of snow, widespread frost and cold winds.
After saturated southern England is hit by further flooding this weekend, low pressure will start to bring change across the UK next week.
Next week's drop in temperature will come as a shock following a wet but exceptionally mild December and January, Sky News Weather Presenter Isobel Lang, said.
"The low bringing us rain this weekend will slip away southwards allowing significantly colder air to seep west and southwestwards across us on a biting east or northeast wind.
"It will be a shock to the system after a mild December, the mildest since 1988, and a mild first half of January with a mean UK temperature up to January 15 of 5.1C, which is 1.5C above average.
"Snow is likely, especially over hills, with more widespread frosts too."
But Lang said the change looked unlikely to last.
"At this stage the Atlantic influence still looks strong and it could be that the cold air pushes back into continental Europe again by the end of the week," he said
The Met Office has warned of a wet and windy Sunday.
It will then turn colder and "increasingly wintry, particularly across northeastern parts", its UK five-day forecast reads.
Its summary for the 10 days from Tuesday warns of biting easterly winds and temperatures near or just below normal.
