Parts of the UK are set to see up to six inches of snow, as drivers were warned of perilous driving conditions in some areas.
Forecasters say the latest snowfall will be followed by rain, before much of the country enjoys a period of sunshine and milder temperatures.
But Sky News weather presenter Isobel Lang urged motorists to be cautious in those areas due to suffer more wintry weather.
"There will be quite a few hours of quite nasty snow and a number of routes are likely to be affected," she said.
"It's mainly going to be in the hilly areas, where there will be between four and six inches.
"The M6 could be particularly badly hit and we're also expecting problems on the M74 in southern Scotland, the A66 in Cumbria and Pennine routes like the M62.
"The snow will be followed by outbreaks of rain in some areas and it is unlikely to settle for long in most parts.
"After that, we can actually look forward to a couple of days of sunshine, when temperatures should be fairly mild for most of us."
The Met Office has issued severe weather warnings for much of Scotland and northern England for today, advising people to be aware of snow fall.
And the Environment Agency has scores of flood alerts in place, mainly in the South East, and several serious flood warnings.
