Default 510 DM cold pool

You will find that the model always overdoes the extent of the low thickness
air, especially at such long lead times.

All

UKMO charts for next Tuesday indicate a 510 DM cold pool heading south
across the UK and eventually tracking into France. Surface air is

dragged
across the UK very quickly from the Arctic, leaving little time for

warming.
My Experience of 510DM cold pools across the UK always produce some very
snowy situations.
14 February 1979 and January 1987 for instance. If I recall correctly
February 1991 in the SE.

In essence 510DM air is the precurser of some of the heaviest falls of

snow.
Wind direction is critical to where the heaviest falls of snow will occur,
but withe the potential for upper vortices there could be a few surprises
in store for heavy snow almost anywhere.
