Information on update: Warning area expanded to cover parts of northwest England, the East Midlands and southern England. An area of sleet and snow is expected to move southeastwards across parts of England and Wales, lasting approximately 2 or 3 hours in any one place. Where snow falls, 1 or 2 cm is likely for some and perhaps as much as 5 cm snow possible in a few spots, especially higher ground of north Wales, northwest England and perhaps the northwest Midlands. Some ice may form as a result of precipitation falling on to frozen surfaces and icy patches will also develop quickly as sleet and snow clears.
