Here is a summary of the latest NWP output for noon on Sunday. Issued 0608z,
1/12/04.

The runs are now showing good agreement of a much more mobile period of
weather, with high pressure to the south and SE and lows moving eastwards in
the vicinity of Iceland. This will bring moderate to strong WSW'lies or
SW'lies to start next week and if the GFS is to be believed the pattern will
last for quite a few days. As ever, more runs are needed.

ECMWF: http://64.246.48.81/pics/Recm1201.gif
A ridge covers the UK, with WNW'lies and NW'lies. The ridge moves ESE'wards
at T+144, allowing SW'lies associated with a trough to the west to affect
the UK. By T+168 pressure rises over England and Wales, with westerlies for
all.

MetO: http://www.wetterzentrale.de/pics/Rukm1201.html
Strong to gale force WSW'lies cover the UK with high pressure over Biscay
and a low to the south of Iceland. The low moves eastwards at T+144,
bringing westerlies and WSW'lies for the UK.

GFS: http://64.246.48.81/pics/Rtavn1201.gif
A large high covers Biscay and France and this leads to moderate SW'lies
across the UK. 850hPa temperatures vary from +1C over NE Scotland to +3C
over much of England and Wales. The winds become westerlies as a weak ridge
moves eastwards at T+144, followed by strong to gale force WSW'lies from a
deep low to the north on day 7. Day 8 sees the low move slowly ENE'wards,
bringing more WSW'lies. WSW'lies continue to affect much of the UK on day 9
as the low fills to the west of Norway. By day 10 the UK lies under SW'lies
from a new low to the south of Iceland.

The Canadian run also shows a high over Biscay and France and SW'lies for
the UK.

GME/DWD:

SW'lies cover the UK, much as with the other runs. High pressure is centred
over France with a ridge bringing lighter winds over southern England. A low
covers Scotland at T+144 with a trough over the UK; winds are strong SW'lies
in advance of the trough and NW'lies behind it. By T+168 the UK lies under
WSW'lies, with high pressure persisting to the south.

JMA: http://www.wetterzentrale.de/pics/Rjma1201.html
The UK lies under a large high, with light winds for most areas. The
exception is NE Scotland, which lies under NW'lies. The high sinks SE'wards
at T+144 to allow WSW'lies for all areas, lightest over southern England. A
new ridge builds to the west on day 7 to bring NW'lies, followed by SW'lies
and WSW'lies as the high builds over northern France on day 8.

NOGAPS: http://129.13.102.67/wz/pics/ngp10.prp.120.europeg.gif
NW'lies cover the UK due to high pressure to the SW and a ridge to the west.

Wales, with westerlies for Scotland.

Well there goes the cold spell, yet again.
