It looks like it'll have lots of cloud mixed up in it - so I guess we
can look forward to a week or so of 8c/6c temperature ranges and gloom.

Don't you not think that with a high of 1040 hPa and high contour values that
will lead to strong subsidence which will tend to lower the subsidence inversion
so that low cloud will disperse? Also do you not think that as the high
retrogresses (moves west) then a cooler (and clearer) northwesterly flow perhaps
later veering northerly could become established ? Initially it may have a lot
of cloud but there's plenty of reasons why it won't persist? Also it is not
clear that the air in the south will have much Atlantic origin could be quite a
lot of drier continental air mixed in in a light SE or even E drift?

Certainly far from being zonal with lots of blocking upto Christmas. GFS
seems to indicated a further northerly plunge nearer Christmas. What
worries me is I don't realy see a Scandi High again this winter as yet :-(

They have always been fairly rare in December, though. They're much more
frequent later in the winter.

I was just flicking through the November / December 1962 charts and the
patterns are not a million miles dissimilar to what we've had and what's
projected upto Christmas. High pressure blocking to the west with
northerly plunges plus blocking to our east / southeast. So who knows?

Will,

Chances are you've forgotten more than I'll even know about meteorology
- so I would never deign to pit my wits against you - but I was looking
at todays UKMO forecast charts - and they all show a decaying front
embedded right through the centre of the High.

Subsidence may lead to an inversion - but the cause of the gloom is not
necessary any consolation for the gloom itself.

Any Northwesterly would be on the West side of a warm front - laden with
moisture to entrain in the high, under the inversion; outcome is
Stratus, Fog and gloom - but not very cold.

If, and only if the High moves North, and we get a day or two of
Easterlies could we see some drier air move in.

We shall see - but for now, I've put the sun-block back in the drawer
