Here is a summary of the latest NWP output for noon on Thursday. Issued
0611z, 19/12/04.

The models continue to show a mobile picture. It now looks like Christmas
Eve will see colder air pushing southwards during the day, behind a trough
and this colder air should cover much of the UK by the end of Christmas
Day.
It could well be cold enough over northern areas of the UK for some snow,
but it's still borderline for much of England and Wales. As ever, more
runs
are needed.

There's an interesting variation in the depth of low in the Norwegian
Sea around Wed/Thu ... a cursory glance through the models (i.e. I
may have missed something) suggests anything from 955mbar
(NOGAPS) to 925mbar (GFS), with a clustering around 940 or
just below. 925mbar that far north and east might possibly be a
record.
