Default Widespread heavy snow next week from 15th

Becoming increasingly confident now that after Monday the snowiest spell
of the winter is about to hit the UK with widespread lowland snow.

The benign cold spell will start to withdraw on Sunday as the high
retrogresses allowing a much colder airmass originating from sub 492 DAM
air near the pole to flood south with sub 522DAM thickness and falling
pressure. Three things will aid snow development:
1. South moving air increasing absolute vorticity forcing ascent and
falling pressure.
2. Decreasing stability forcing convection
3. Northerly jet streak propagating south from Iceland forcing mass
ascent of air on its cold side (over UK).

I have kept quiet till now wanting to see how this was likely to pan out
but now it is becoming clearer when the serious snow will arrive - from
Monday onwards for about a week. Get those snow shovels ready, nobody
will be immune, even lowland coastal SW areas.

Ciao, :-)

Have you been at the Gin cupboard again?

Wow - some forecast. I have things to do next week that will be impacted
by such a scenario - so once again, I hope you are wrong.

Can't you forecast something nice for us?
