Default Today's model interpretation (11/08/05)

Here is a summary of the latest NWP output for 12z on Monday. Issued 0556z,
11/08/05.

The runs show high pressure influencing the UK for the first half of next
week, with settled (and potentialy warm) weather for England and Wales.
Elsewhere, due to being on the periphery of the high, it's likely to be
windier with a higher chance of rain.

ECMWF: http://64.246.48.81/pics/Recm1201.gif
England, Ireland and Wales lie under a ridge from the Azores High, with
westerlies elsewhere. There's little change at T+144, although the winds
become SW'lies for Scotland. By T+168 a trough approaches the UK from the
west, resulting in SW'lies across Northern Ireland and Scotland. The
remainder of the UK continues to lie under a ridge, with light winds.

MetO: http://www.wetterzentrale.de/pics/Rukm1201.html
MetO shows westerlies for all with high pressure to the south. The high
declines at T+144, although a weak ridge brings lighter westerlies and
SW'lies to the UK.

GFS: http://expert.weatheronline.co.uk/pslv_frame.htm
The UK lies under a mixture of westerlies and NW'lies, due to a ridge to the
SW. 850hPa temperatures vary from +7C over SE England to +9C over Scotland,
Northern Ireland and SW England. The ridge builds and moves NE'wards at
T+144, bringing lighter winds across Egland and Wales. Elsewhere SW'lies
cover much of Northern Ireland and Scotland, as is the case at T+168 as the
ridge persists over England and Wales. A small low moves over Scotland on
day 8, bringing strong NW'lies to Northern Ireland and SW'lies elsewhere,
followed by NW'lies for all at T+216 as pressure rises to the west. By day
10 pressure builds over southern England, resulting in strong westerlies or
WSW'lies elsewhere.

GEM: http://www.meteocentre.com/models/glb00_120.html
The Canadian run shows westerlies for all with a weak ridge over Ireland.
T+144 sees WSW'lies over Scotland and Northern Ireland, with a ridge
bringing light winds elsewhere.

GME/DWD:
http://www.wetter.com/home/img/sat/g...110000_120.gif
A ridge covers the UK, bringing SW'lies to Northern Ireland and Scotland,
with light and variable winds elsewhere. By T+144 the ridge moves SE'wards,
allowing westerlies to affect all areas.

JMA: http://www.wetterzentrale.de/pics/Rjma1201.html
The Japanese run shows similar setup to DWD, with a well defined ridge
covering the UK and resultant light northerlies and NW'lies. The upper ridge
moves across the UK at T+144, accompanied by a surface ridge over England
and Wales. Winds are light there, but elsewhere winds are SW'lies ahead of a
trough to the west.

NOGAPS: http://wetterzentrale.com/pics/Rngp1201.gif
Northerlies and westerlies cover the UK, due to a ridge over Ireland. The
ridge becomes a high over England, Wales and Ireland at T+144, leaving
Scotland under westerlies.

KMA: http://www.kma.go.kr/kma03/gif/g21nh_smsr_120.gif
The Korean run shows also shows a mixture of northerlies and westerlies,
with a high to the WSW.

That forecast could be cut & pasted, and applied for most of this
summer...

It could be cut-n-pasted for much of the year I'd bet! I've a feeling I'll
be writing something slightly different for tomorrow's effort though:

There's a massive spread in the ensembles tonight, but it's looking
increasingly likely that the end of next week will see some warm if not hot
conditions down here.

Those very hot outliers remind me of the occasional -15C runs you see in
winter - and from my point of view I hope they're just as likely to come
off!
