Today:
Snow showers down the eastern side again. How far inland (particularly in the NE England up) will they penetrate far inland again as they did yesterday? I don't know!
Christmas day:
(drum roll)
A good part of Scotland and some of the very north of England will see snow! There may be a little snow in East Anglia and the SE too. Both GFS and UKMO show this (but each in a different place)
Boxing day:
The atlantic weather coming in looks much slower now. Scotland, NI and parts is the first to be hit by the atlantic weather in the early evening which is as yesterday predicted. Probably snow to start.
Monday:
The atlantic weather moves in!
Timings are different in the two models I look at so I shan't give them. Roughly speaking GFS shows it affecting only half of the UK by evening. The UKMO has it covering most of the UK by dawn!!! Big differences. Nevertheless, this is one to watch. Significant snowfall may occur in places, followed by rain.
Tuesday:
Milder air moves in. again some discrepancies. GFS is still more reluctant to move the warm air in than the met office. Overall though I would think temps go positive for most and significantly so for the south and west.
Katymac - you may get a little colder than -3 (depends whether you are in a town or frost hollow) -3 is probably the maximum minimum temp you would see over Christmas day night.
notsure - timings are so tricky!! I think you would be ok coming back in the morning TDABD, but don't hold me to that!
Well all, I'll be around this morning on and off for the odd question but then I shan't have the opportunity to look at the weather models until after Christmas. So I'd like to take the opportunity to wish you all a Very Happy Christmas. Stay safe and stay warm
