This will probably affect some higher elevations, leading to possible disruption, mainly to travel.
Some roads and railways are likely to be affected by snow or ice, leading to longer journey times by car, as well as by bus and possibly train services
Some short term loss of power and other services is possible
As an area of rain moves northwards, it looks like turning to snow over the higher parts of Northern England, and then southern and central Scotland.
Coupled with strong winds, gusting to 35 to 45 mph in places, this is likely to lead to some difficult travel conditions across higher Pennine and Cumbrian routes, as well as the Southern Uplands, during the early hours of Sunday.
Temporary blizzard-like conditions may be encountered above around 300 or 400 metres elevation.
These conditions will probably move into some hillier central parts of Scotland during Sunday morning, while snow turns back to rain further south.
The extent of snowfall is uncertain at this stage, and so it will be particularly worthwhile keeping up to date with the forecast.
The forecast for the Christmas weekend for the Yorkshire Coast is as follows:
