Expect some significant and disruptive snowfall in the next 24 hours.
Snow flurries will drift into some eastern regions overnight. As a batch of rain sweeps into the west, it will turn readily to snow across Northern Ireland, Wales, the West Country and much of the Midlands by dawn.
Winds will pick up bringing blowing snow and blizzard conditions over western hills.
The snow will become increasingly widespread through the morning rush hour - giving awful conditions if you have to travel.
