As sub-tropical air lifts north, so arctic air comes down on the other side!

What a difference 24 hours makes here in Scotland and particularly for the central Highlands. It was a heavy coat walk with my daughter Holly to the nursery for 8am yesterday morning. This morning I could have gotten away with a t-shirt!

Thanks to warm, moist SW winds crossing the Cairngorms/Grampians, we could see 17, possibly 18C on the Moray Coast or over NE Aberdeenshire this afternoon.

Scotland’s December record of 18.3C set back in 1948 at Achnashellach is likely to remain standing.

However, Northern Ireland may have already tied if not broken their December record. The December record stands at 16C set back in 1984 at Murlough and Eglinton, Londonderry appears to be sitting on the figure as of this writing.

Here’s the reason why we’re seeing night time minimums WARMER than daytime averages for Dec 7.

A rather deep low and associated trough south of Greenland and cold high pressure over Europe is creating a channel and driving warm, moist mid Atlantic air NNE in over the UK.
