Default Potential long wave axis shift

Not really time to say much but if you look at the DT00Z ECM ensemble mean
SLP charts you will see the predominant surface low transferring from west
of Iceland at T+168 to between Iceland and Norway by T+240. This will
indicate a breakdown of the predominantly anticyclonic conditions in
southern Britain and another zonal cold low-latitude W'ly establishing with
plenty more action!

PS Wednesdays low is looking mighty interesting but potentially very severe
in terms of wind for Scotland.

That possibility has been on the charts for the last few days - it is,
after all, only at 7 days. It does look as if the low west of Iceland
may well be replaced by another a few days later, bringing us back
into a similar regime. Is this a forecast of the establishment of a
colder trend, rather than a temporary lee effect, as you would expect
in a zonal flow?

I think you're clutching at straw's Will and I'll be the first one to
eat humble pie this winter. But, winter hasn't really started yet and
it could take off half way through January. Now who's clutching
straw's ;-)

I've been watching developments myself Will.
It does look a bit tasty on Thurs and Friday where I'm going.
Namely Finland.
Better take my scarf and long johns.

God Jul and Hyvää Joulua!

as they say in those parts.

You were right Keith. It was likely to be straw-clutching and it looks
like it will be. It looks like a 2 - day lee effect as the train of
depressions continues to cross us. Colder, for a couple of days, Thurs/
Fri, with some snowflakes for Haytor, potentially, but a temporary
cooler spell; no more. The CET looks like it will probably come out
just above average for December.
