Here is a summary of the latest NWP output for noon on New Year's Day.
Issued 0557, 28/12/05.

The models show a changable period for the start of the new year with
transitory ridges and troughs moving across the UK. NW'lies look likely for
most areas on New Year's Day, followed by drier weather as a ridge moves in
from the west.

ECMWF: http://217.160.75.104/pics/Recm1201.gif
Low pressure covers the North Sea, leading to NW'lies for the UK. A
transitory ridge moves eastwards at T+144, bringing a mixture of WSW'lies
and SW'lies to the UK. SW'lies cover much of the UK at T+168 as a secondary
low passes close to Scotland.

MetO: http://217.160.75.104/pics/Rukm1201.gif
MetO shows moderate westerlies for Scotland due to a low to the north.
Elsewhere winds are lighter westerlies or WNW'lies, followed by SSW'lies and
southerlies across the UK at T+144 as a trough crosses the British Isles.

GFS: http://217.160.75.104/pics/Rtavn1201.png
GFS shows a ridge over the UK, leading to NNW'lies across most areas. The
ridge moves SE'wards at T+144 as a trough pushes eastwards over Northern
Ireland. Winds there are westerlies with SW'lies elsewhere. By T+168 another
ridge approaches the UK from the west with light northerlies or NW'lies as a
result.

GEM: http://meteocentre.com/models/glb00_120.html
The Canadian output shows NW'lies for all with low pressure to the east of
Scotland.

GME/DWD:

DWD is very similar to GEM in that a low is centred east of Scotland,
leading to NW'lies across the UK. A trough moves in from the west at T+144
to bring SW'lies, followed by NW'lies at T+168 as the trough moves over the
North Sea.

JMA: http://217.160.75.104/pics/Rjma1201.gif
The Japanese run shows NW'lies for all with a low over the North Sea. A
trough moves eastwards at T+144, introducing SW'lies across the UK.

NOGAPS: http://217.160.75.104/pics/ngp10.prp.120.europeg.gif
NOGAPS shows a large low over France bringing NE'lies for all. The winds
fall light at T+144 as the UK lies under a ridge.

The Korean run shows a ridge to the west and NW'lies for the UK.
