This forecast is very difficult indeed to make, and I don’t have a lot of confidence in it. The models have been handling things very poorly in recent days, Saturdays snowfall is still uncertain and it’s just over 12 hours way. I think the most likely areas to be affected by the snowfall tomorrow will be areas South of the M4, so South-West England, Central Southern England and South-East England. Extreme coastal areas may see sleet/wet snow, though I think even here snow is likely to settle. Accumulations will range from 5-10cm with local accumulations of 20-25cm. Further North it’ll be generally dry, cold with snow showers flirting with coastal areas.

Through into Sunday another low pressure system looks likely to push along Southern England, again there is a lot of uncertainty about this system and a slight shift in track will mean the difference between heavy rain and heavy snow, so this situation will have to be closely monitored, in fact, another Low Pressure system looks likely for Monday, but I’m can’t go into detail about this yet.

So over the next 3-4 days, significant snowfall likely across Southern areas, this perhaps extending Northwards into parts of Wales and the Midlands, elsewhere cold and dry, but always the risk of some snow showers popping up out of no where. The trend through this week and towards Christmas is for things to remain cold with further snowfall in places.

If you’re worried about the snowfall, I’d advice you to keep up-to date with your local weather forecasts and radio forecasts, they see new model information far quicker than I have access too, though please bare in mind even the expert forecasters are really struggling with such a complex weather pattern.
