Default Today's model interpretation (20/09/06)

Here is a summary of the latest NWP output for noon on Saturday. Issued
0537z, 20 September 2006.

The models continue to show relatively warm conditions, albeit with low
pressure to the south leading to winds from an easterly quarter. There's a
risk of rain moving up from the southwest for the beginning of the week, but
even at this range the models are quite varied due to their handling of
Helene.

ECMWF: http://85.214.49.20/pics/Recm1201.gif
The UK lies under a SE'ly flow due to a low to the SW. Winds fall light at
T+144 due to a col. By day 7 a weak high moves across the North Sea,
bringing easrerlies to England and Wales with southerlies elsewhere.

MetO: http://85.214.49.20/pics/Rukm1201.gif
The MetO run shows high pressure to the NE and ESE'lies over the UK. The
high builds at T+144, introducing ENE'lies for England and Wales with
ESE'lies and SE'lies elsewhere.

GFS: http://expert.weatheronline.co.uk/pslv_frame.htm
As with ECM, SE'lies cover the UK, this time due to a trough to the SW and a
high to the north. The winds become easterlies for many at T+144 as low
pressure moves over France. By day 7 a trough moves northwards over England
and Wales, bringing light winds there and southerlies elsewhere.

GEM: http://meteocentre.com/models/glb00_120.html
The Canadian run brings low pressure over England and Wales with easterlies
elsewhere.

JMA: http://85.214.49.20/pics/Rjma1201.gif
The Japanese run shows a mixture of ESE'lies and easterlies, with a high
over Iceland and a low to the SW.
