Here is a summary of the latest NWP output for 12z on Tuesday. Issued 0555z,
12/08/05.

The runs continue to show high pressure having an effect on the UK next
week, with increasingly settled weather the further south you are. A deep
low will move close to Iceland and its associated trough looks like crossing
the UK at some stage; GFS and ECM show this on Thursday into Friday. MetO
shows a different scenario with the ridge being kept at bay by a large high
to our east.

ECMWF: http://64.246.48.81/pics/Recm1201.gif
A ridge covers England and Wales with light winds there. Elsewhere winds are
SW'lies due to a deep low to the WSW of Iceland. The ridhe moves away to the
east at T+144, allowing SW'lies to affect much of the UK. A trough crosses
the British Isles at T+168, leaving westerlies for all.

MetO: http://www.wetterzentrale.de/pics/Rukm1201.html
MetO shows high pressure over the North Sea, resulting in SW'lies for
Scotland and Northern Ireland and light winds elsewhere. The high builds
over Denmark at T+144, introducing easterlies, SE'lies and southerlies for
the UK.

GFS: http://expert.weatheronline.co.uk/pslv_frame.htm
As with ECM, SW'lies cover Scotland and Northern Ireland with a ridge over
England and Wales. 850hPa temperatures vary from +9C to +11C over the UK. A
trough approaches from the west at T+144, leading to SSW'lies followed by
westerlies at T+168 as the trough moves swiftly eastwards over the North
Sea. Westerlies persist on day 8 before another trough approaches from the
west to bring SW'lies on day 9. The trough slowly moves across the UK on day
10, with SW'lies in advance and NW'lies behind.

The Canadian run shows SW'lies across the UK at T+120 and T+144 due to a
deep low to the NW and a ridge to the SE.

GME/DWD:

The UK lies under a large ridge, with light winds for all. The ridge moves
eastwards at T+144, allowing southerlies to affect most areas.

JMA: http://www.wetterzentrale.de/pics/Rjma1201.html
The Japanese run also shows a ridge with light winds. The ridge becomes a
high over the North Sea at T+144, with southerlies for all.

Should that read "trough being kept at bay"?
