Here is a summary of the latest NWP output, for noon (GMT) on Monday. Issued
0605z, 21/08/03.

ECMWF: http://www.wetterzentrale.de/pics/Recm1201.html
A ridge from the Greenland High extends SE'wards over Iceland and the UK,
bringing northerlies and NE'lies across much of the UK. The ridge builds to
the NW of the UK at T+144, with moderate northerlies and NNE'lies for all.
The winds continue at T+168 as the high sinks southwards to the west of the
UK.

MetO: http://www.wetterzentrale.de/pics/Rukm1201.html
The UK lies under high pressure, with light winds for all. The high persists
at T+144, with little change in conditions over the UK.

GFS: http://www.wetterzentrale.de/pics/Rtavn1081.gif
Light easterlies cover the UK, with high pressure to the NW. There's little
change at T+120, with 850hPa temperatures ranging from +7C over East Anglia
to +13C over SW England. The high builds over the UK at T+144, with light
winds for most. By T+168, the high moves SE'wards and declines, leaving
light southerlies and westerlies over the UK. Low pressure then dominates
the UK on day 8, with SW'lies over England, Northern Ireland and Wales.
Scotland lies under easterlies. The low moves NE'wards over southern Norway
on day 8, with NNW'lies over much of the UK. Southern and SE England lie
under WSW'lies, though, as is the case on day 10 as the next low moves
closer to the UK from the west.

The Canadian run shows high pressure to the NW, leading to easterlies over
much of the UK. The eastern half of the high sinks southwards over the
British Isles at T+144, with light winds for all. The high declines over the
UK at T+168, before southerlies ahead of a low move over Ireland on day 8.
The low covers Ireland on day 9, with moderate southerlies over much of
England and Wales; Scotland lies under easterlies. By day 10 the low moves
away to the east, allowing moderate northerlies and NE'lies to affect the
UK.

JMA: http://www.wetterzentrale.de/pics/Rjma1201.html
As with the other runs, a large high lies to the NW of the UK, this time
bringing light NNW'lies for Scotland and Northern Ireland, with ENE'lies
elsewhere. 850hPa temperatures range from +8C over northern Scotland to +13C
over SW England.

The T+108 chart shows a ridge over the UK, with low pressure well to the
WSW.

In summary, the runs today persist in showing a largely settled start to the
week, with high pressure dominating the UK. There are difference between the
runs, though, with winds forecast to be from the north or NE (ECM), east
(Canadian) or light and variable (GFS, MetO). As ever, more runs are needed.
