Here is a summary of the latest NWP output for noon on Thursday. Issued
0526az, 9 July 06.

Much of England and Wales will be very warm or hot towards next weekend,
with light winds and plenty of sunshine. Further north and west things are
less certain, but it should become a fair bit warmer there as well.

ECMWF: http://85.214.49.20/pics/Recm1201.gif
A ridge covers the UK, bringing light winds to England and Wales with
westerlies elsewhere. There's little change at T+144, but by T+168 high
pressure recentres over Scotland, which leads to ENE'lies elsewhere.

MetO: http://85.214.49.20/pics/Rukm1201.gif
A trough lies to the west of Scotland, resulting in SW'lies for Northern
Ireland and Scotland. Elsewhere winds are light due to a weak ridge from a
high to the NE.

GFS: http://217.160.75.104/pics/Rtavn1201.png
England and Wales lie under a ridge with light winds. Elsewhere winds are
WSW'lies with a deep low east of Iceland. The ridge builds and moves
NE'wards over the North Sea at T+144, bringing light winds across Scotland
and Northern Ireland. An ENE'ly picks up elsewhere, but by T+168 winds fall
light for most regions as the high to the NE declines.

JMA: http://85.214.49.20/pics/Rjma1201.gif
The Japanese run brings a ridge from the Azores High across Ireland, leading
to SW'lies for Northern Ireland and Scotland. Elsewhere winds are NNW'lies.

NOGAPS: http://85.214.49.20/pics/Rngp1201.gif
NOGAPS shows high pressure extending from 1000 miles west of the Azores
NE'wards to the UK and across the Baltic. Winds are SW'lies for Scotland and
Northern Ireland, with NE'lies for much of England and Wales.

Out of curiosity, what temperature is the dividing line between 'very
warm', and 'hot'?

My personal definition would be 80°F.

warm', and 'hot'?
According to the MetO, 4 to 5C above average is "very warm", 6C or 7C above
is "hot". 8C or more above the mean is "very hot".
