GFS 12z so far..
A bit blowy on Christmas Day but thankfully nowhere near as bad as it could have been http://old.wetterzentrale.de/pics/Rtavn721.gif
Very mild..
Midnight into Boxing Day it's a different story and it could turn pretty wintry in parts of Scotland http://old.wetterzentrale.de/pics/Rtavn841.gif Boxing Day itself it'll feel seasonal for most http://old.wetterzentrale.de/pics/Rtavn10217.gif
Moving into Tuesday 27th HP pushes in and we get the first of our overnight frosts. In fact Tuesday 27th should be a cracking day for many.

Another frost for some into Wednesday morning with continental SE'ly winds http://old.wetterzentrale.de/pics/Rtavn1381.gif
Then another one for some into Thursday morning http://old.wetterzentrale.de/pics/Rtavn16217.gif
Friday night into NYE more of a SW'ly tilt, but with more signs of amplification in the Atlantic and a weaker PV. FI, FWIW, shows signs of a toppler scenario, just like the 06z.
In summary, very mild on Christmas Day, less stormy than it could have been (phew), cold on Boxing Day with snow for some in Scotland, then turning colder and frosty with SE'lies up until NYE (albeit less cold in the NW).
After that, uncertain, but no real signs of extended zonality or especially mild weather.
