There’s been some very interesting output on the weather models these past couple of days – not least the GFS’s dew points from Christmas Day into Boxing Day.

Very cold air from the east can be seen moving toward the SE of the UK to just across the North Sea – one run has the dew point down to -20C!

The outcome will be different but it’s been a fair while since I’ve seen this sort of solution in what is a relatively short timeframe.
