Note: I've to leave early today - hence this is a shorter analysis. Normal
service will be resumed tomorrow morning.

Here is a summary of the latest NWP output for noon (GMT) on Tuesday. Issued
0445z, 22nd August 2008.

The middle of the week still looks like seeing a NW/SE split. Beyond that
pressure will rise and settled conditions will spread across much of the UK.

ECMWF: http://85.214.49.20/wz/pics/Recm1201.gif
The UK lies under SW'lies, between a low over Iceland and a high over
France. There are further SW'lies on day 6 and on day 7 high pressure lies
to the south of Ireland, leading to a mixture of WNW'lies and westerlies for
the UK.

MetO: http://expert.weatheronline.co.uk/da...ukmo/pslv.html
MetO has moderate SW'lies, again with a low over Iceland. There are further
SW'lies on day 7 as low pressure fills to the north.

GFS: http://85.214.49.20/wz/pics/Rtavn1201.png
A ridge covers England and Wales, with SW'lies elsewhere from a low over
Iceland. The winds become NW'lies and WNW'lies on day 6 as a ridge builds
over Ireland, followed by further NW'lies for most on day 7.

GEM: http://expert.weatheronline.co.uk/da.../gem/pslv.html
The Canadian run shows WSW'lies with a similar setup to the other models.

JMA: http://85.214.49.20/pics/Rjma1201.gif
The Japanese run shows WSW'lies too, again with a low near Iceland.
