Just had a look at all this morning's outputs and I have to say that we
have the
best chance for a widespread white Christmas in the UK for years ! I rate
it at
75% now. I see no reason to change my weekly forecast issued on Friday,
however,
there could be a surprise for the south in that pressure falls to the SW
could
induce a shallow Channel low bringing a spell of sleet and snow as the
colder
air continues to advect south. If you calculate the thicknesses on the
UKMO
output and of course looks at the GFS they all show deep cold air over the
UK on
Xmas Day. So anywhere could get a spell of snow, even in normally mild
areas
like Torbay and Penzance ! But obviously high ground and areas away from
the
south coast have the greater chance.
Looking further ahead, it still looks like milder air will spread in on
Boxing
day bringing a spell of snow turning to rain, much as my weekly forecast
suggested.
Old forecasting lags will also know that even though one can get snow in
such
situations, you never get a severe blocked and prolonged cold spell with
low
pressure near Scandinavia, the Atlantic will always easily bring in milder
air.
But enjoy it while it lasts, it could be a memorable Christmas
weatherwise.
Cheers,
Will.
