The big freeze across the UK is set to last with more snow expected next week.
With travel chaos across the country and Britain's busiest airport being likened to a "refugee camp" amid more than 100 cancelled flights, forecasters predicted further misery in the coming days.
Following Friday's deluge of snow, much of Saturday's snowfall was limited to the North East of England and the east of Scotland. But on Sunday, a blanket of snow is expected to fall across more of the nation, hitting London and the South East of England first before moving north.
Laura Caldwell, of MeteoGroup, the weather division of the Press Association, said: "There will be a few snow showers but heavier snow moving into the south of England and spreading into the Midlands, north east Wales, East Anglia and central England. There will be a quite significant accumulation and it will be seen first in London and the South East before moving north later in the day."
Freezing temperatures which have chilled the UK for the past week will also combine with more snow in northern England as next week begins, Ms Caldwell added. "It is not going to be getting warmer any time soon," she said.

The Met Office has issued yellow warnings for ice over much of the country - and a red, severe warning for South Wales which experienced the worst of the weather.
