Well according to UKMO outputs. On the face of it we have the continuation of
high pressure, but .... if you calculate the thickness from the 500 mb height
field you will see a 528 DAM cold pool migrating NW'wards on Tuesday across SW
England and Wales. Cold pools can give an hour or two of continuous snow
especially if it is deep and extends to 300 hPa level (which I cannot see), but
certainly something to watch out for despite the high pressure. Sea temps. could
enhance the snow too maybe giving substantial falls over high ground SW England
and Wales given the cold surface feed off the continent.

Glad to see it's only SW England & Wales affected, and that Cornwall's
not mentioned. Quite chilly enough for me today now we've picked up a
fresh SE. It might not reach 10C in Penzance, and that's only happened
once so far since the summer (8.5C on 23rd Nov).

Nice & sunny again though.

Little update on Sundays gale. The emergency services got around 50
call outs, mainly for fallen trees & power cables. There were 4 boats
sunk in St Ives harbour, and a broken mast crushed a car next to
Penzance harbour. There were a number of road closures including the
A30 near Newlyn Coombe.
