I dont reckon so.
So far as Bournemouth is concerned, it will just be a tad nippy for a few
days before the westerlies come back. No snow for us, we almost never get
snow down here under that set-up.
Jim, Bournemouth.

This will be my last one until the regular one next thursday.
Hopefully I'll be sending in snowy [WR]s soon.
Still unsure about rain/snow from low in Channel/north France on
Sunday/Monday.
GFS very enthusiastic about precipitation in the "cloud head", Met
Office
much
less so. Heavy precipiation will mean rain turning to snow down to
quite
low
levels, light precipitation (as per Met Office) will mean no snow
below
300m.
Anyway very cold Arctic air set to flood south on Monday to all parts.
The
air
is racing off Greenland plateau at about 80 knots and hurtles south
initially
with little chance of warming, this is what makes it so special.
Detail of snow still uncertain but some places are going to get 30 cms
or
more
and others are going to get practically nothing. Best I can do is to
say
that if
you have a maritime fetch not far upwind or are on a slope facing the
wind
then
you will get snow showers otherwise you will be relying on synoptic
features
like polar lows, cold pools or troughs. All depends crucially on wind
direction.
Regions *least* likely to get a lot of snow are those sheltered from
winds
NW-NE. eg Dorset, Hampshire, central lowlands Scotland. Those regions,
however
will still be bitterly cold, but temperatures over snow cover could
easily
fall
below -12 deg C.
Devon and Cornwall will get snow showers provide the wind stays N-NW
:-)
Hint that on thursday things quieten down a bit in the west with more
sunshine.
Conversely Kent and East Anglia become threatened with substantial
snow
on
Weds
and Thurs due to wind possibly coming more directly off the North Sea.
London
not immune, particularly eastern side.
Finally it is now looking more likely (40%) that warmer air will
encroach
from
the SW late Friday/early Saturday, as it meets the very cold air wedge
near the
surface appreciable snow turning to rain seems likely. The trouble
then
becomes
how far and how fast it moves north ?
OK good luck everyone in both mild and cold respects, stay safe and
look
after
yourselves, and above all else *enjoy* whatever you get, we don't get
these cold
spells very often nowadays.
Will.
