Following a soaker of a Saturday across Ireland, Wales, central and southern England, there was a very impressive spread in UK temperature overnight. We’re separated by two very different air masses.

Over the snowfields of Highland Scotland and beneath, clear, cold, calm skies it got down to -9C at Dalwhinnie, widely -2 to -4C but the Southern half of the country, it was quite different. Parts of the Southwest didn’t get below +12 or 13C!

Less rain but still damp and mild across southern parts, dry, bright but cold with many barely getting above freezing in Scotland, especially where there’s snow or lingering fog.

The mild makes a return this week as the next Atlantic system lifts north. A warm front will eventually kick the cold out during Monday.

Snow is quite possible this eventually as moisture bumps into the cold in place.

With strong heights over Europe and a slower jet (to start off the week), lows will be weaker and moving south to north. Tracking to the west means we remain in the mild southerly flow. By late week, we see an increase in jet with deeper lows into next weekend moving from SW to NE, still largely mild with return of backside cold and it should be wetter and windier. Cold over central and eastern Europe.

With a little more amplification to this week’s upper pattern thanks to a slower jet which can buckle more, it’s a colder, snowier week for eastern Europe.

It’s merely one run but it would appear the ECMWF tries to build heights west and north of the UK which turns winds in from a NE direction and it shows cold air over Scandinavia.
