Darren Prescott drew our attention to a possible northerly airstream
for the coming weekend and this possibility is worth checking.

On 22nd September the cold air should cover the British Isles with
winds from a NW direction.

On 23rd, warmer atlantic air approaches the British Isles from the W.
By the 24th a HP builds up over the SW of Britian in front of a LP over
mid-Atlantic and draws warmer ait into Europe over the next 3 or 4
days.

So this one appears to be only a small, cold period from the NW.

Us cold-weather-lovers are also straw-clutchers.

Cold enough for the first ground-frost this autumn?

BTW, on the Wettercarte pressure maps, what does the black line to the N
of Britain represent? Is it a jet stream?
