The UK looks set to be plunged into freezing conditions for some 48 hours with temperatures plummeting as low as -12C in some places, the latest weather maps show.
Britons hoping for a white Christmas may see their wish granted with maps showing snow in Scotland, the North of England and parts of Wales on December 25, according to maps generated by WX Charts.
That picture looks set to continue for at least the following two days, with snow on Boxing Day, December 27 and possibly into the weekend if WX Charts’ maps prove to be accurate this far out.
Snow depths of 12cm on high ground in central Scotland and 14cm in the Pennines also appear on maps for December 26-27.
Meanwhile, one map has turned icy blue showing minimum temperatures of -12C around Fort William at midday on December 27. Elsewhere, Dundee could see -1C, Newcastle 0C and Carlisle 0C to -1C, according to WX Charts.
A map generated on Friday (December 13) by Netweather shows the highest risk of snow at 6am on Christmas Day affecting the southern half of Wales and the south of Scotland. There is also around a 50% risk in the Home Counties, the map shows.
While the maps suggest it will be a white Christmas, the Met Office said on Wednesday that it is too early to call.
The forecaster said single models aren’t reliable enough to come up with a detailed forecast and are only part of a wide range of information required to give a full picture.
Forecasting “impactful snow” is said by the Met Office to be especially tricky in the UK, with a number of factors expert meteorologists look for and numerous competing elements which all have to be exact for snow to fall.
The Met Office said: “Sometimes, just a fraction of a degree in temperature can make the difference between the chance to build a beautifully formed snowman, and the joys of a sleety slushy day.”
