Default Today's model interpretation (20/08/06)

Here is a summary of the latest NWP output for noon on Thursday. Issued
0536z, 19 August 2006.

The models show a westerly regime on the way for the end of the week, with
transient ridges and troughs, with all areas seeing rain at times.

ECMWF: http://85.214.49.20/pics/Recm1201.gif
A ridge and light winds cover the UK. A trough moves in from the west at
T+144, resulting in SSW'lies over Scotland, Wales and Northern Ireland. Much
of England remains under a ridge with lighter SW'lies. By T+168 the trough
moves over the North Sea, leaving a mixture of NW'lies and WNW'lies in its
wake.

MetO: http://85.214.49.20/pics/Rukm1201.gif
The Met Office run shows low pressure to the west and a ttrough over the
Irish Sea and Wales. Winds are a mixture of southerlies and SE'lies over the
UK, followed by NE'lies for many areas at T+144 as the low moves eastwards
over East Anglia.

GFS: http://expert.weatheronline.co.uk/pslv_frame.htm
England lies under a trough whilst a ridge brings light winds elsewhere. The
trough fills over the English Channel at T+144 and by day 7 a ridge covers
England and Wales, with SW'lies elsewhere.

GEM: http://meteocentre.com/models/glb00_120.html
A ridge covers the North Sea, leading to SW'lies over the UK.

JMA: http://85.214.49.20/pics/Rjma1201.gif
The Japanese run shows a ridge atop Ireland, with SW'lies for Northern
Ireland and Scotland. Elsewhere winds are NW'lies.

NOGAPS: http://85.214.49.20/pics/Rngp1201.gif
