Further snowfall is expected from the west during the second half of Friday as another weather front moves eastwards across the UK.
Snow will reach eastern parts of England during the evening, likely to clear the coast by the early hours of Saturday.
This means a good few hours of moderate to heavy snowfall. 4 to 8 cm is likely quite widely within the amber warning area, with a low risk of more than 10 cm locally even on lower ground.
Further north, accumulations of 10 to 20 cm is possible over higher ground. The Pennines and the North York Moors are at greatest risk in our region.
Strong winds will also lead to drifting and blizzard-like conditions, particularly over higher level roads.
A difficult and potentially disruptive Friday evening rush hour is expected.
