You must be looking at a different 12Z ECM from me! The operational run
generates a very deep and slow-moving low in the Atlantic that pushes
southwesterlies and westerlies across the UK from Christmas Day onwards..
It could hardly be more different from the operational 12Z GFS, which
sticks an intense High over the UK for most of the post-Christmas week.

Looking athttp://www.meteociel.fr/modeles/gfse_cartes.php
the 12Z ECM is an outlier.
There have been 3 broad solutions so far (in all models):
1. Rapid return to Sw'lies
2. Build of pressure over UK then a battleground
3. Faster build of pressure over Scandinavia and a quick return to an
easterly.

Ihave some thunder type spells showing up. Not sure how a greenland
high will affect them though:

I remember reading a pdf you wrote about the cloudburst type weather
we sometimes get. You said something diametrically opposed to my
belief about thunder storm peaks June July August.

If these two fail to appear the reason will be an explanation to your
error in that.
Sorry I can't remember the title off..ahem..hand... errm
