Here is a summary of the latest NWP output for noon on Saturday. Issued
0618z, 9/11/04.

The runs are now split. The main ones (MetO, ECM, GFS) all show this
weekend's cold spell being a shortlived affair, with lows travelling around
the displaced Azores High to bring a form of zonality thereafter. Many of
the minor runs still show a colder northerly blast, but I'd say the chances
of more than a couple of days of cold weather across the UK are receding. As
ever, more runs are needed.

ECMWF: http://64.246.48.81/pics/Recm1201.gif
Northerlies cover the UK as the result of a large high to the SW. The high
sinks SE'wards at T+144, bringing westerlies followed by stronger westerlies
at T+168.

MetO: http://www.wetterzentrale.de/pics/Rukm1201.html
The MetO run shows a ridge to the NW and a high to the SW, leading to
northerlies and NNW'lies; they're near gale force over Scotland. The ridge
topples SE'wards at T+144, bringing a continuation of northerlies for most.

GFS: http://64.246.48.81/pics/Rtavn1201.gif
The UK lies under westerlies, NW'lies and northerlies as the result of a
large high to the WSW. The high declines at T+144, allowing westerlies to
affect all areas.

The Canadian run shows high pressure to the NE of the Azores, with lows
moving around it. A ridge extends northwards to Iceland, bringing strong
NNW'lies across the UK. 850hPa temperatrues range from -8C over northern
Scotland to -2C over SW England. The ridge moves over the UK at T+144,
bringing ligh winds for most.

The Japanese run shows NNW'lies for all due to high pressure to the WSW.
850hPa temperatures vary from -10C over northern Scotland to -5C over
Cornwall. The winds become northerlies at T+144 as a ridge moves eastwards,
followed by SW'lies and NNE'lies on day 7 as the ridge topples over the UK.
Day 8 sees the high centred over Wales with SW'lies for Northern Ireland and
Scotland.

over the UK.
