Snow showers, which will have been affecting eastern areas of England from Sunday night, are likely to become heavier, more frequent and more widespread through Monday afternoon.
There is the potential for accumulations of 5-10 cm in places, whilst nearby locations may see much less frequent showers and only small accumulations of 0-2 cm.
Further snow showers are expected through Tuesday, these likely to be heavy in places and probably aligned in bands.
Where this happens, there is the potential for 5-10 cm of powdery snow accumulating, possibly very locally 15 cm, through the morning, before easing during the afternoon.
Meanwhile some nearby locations may see only small accumulations of 1-3 cm.
Further snow showers are expected through Tuesday, with the likelihood that a more organised area of snow will push southwest during the morning, bringing 5 to 10 cm of snow in places in just a few hours.
Strong winds may lead to drifting of lying snow (and severe wind chill) especially over hills, with lightning perhaps an additional hazard near North Sea coasts.
Snow showers will bring very variable snow cover, with the potential for a further 10-15 cm of snow in places where showers are most frequent, most likely over higher ground of northeast England and eastern Scotland, whilst nearby locations may see only small accumulations of 1-3 cm.
Strong winds will likely lead to drifting of lying snow, as well as a severe wind chill.
