As usual for a Sunday in the summer half of the year I'm off to the wolves
soon, hence this shorter analysis.

Here is a summary of the latest NWP output for noon on Thursday. Issued
0511z, 19th AUgust 2007.

The models show a warm and generally settled end to the week. Beyond the
weekend they differ widely, however, with GFS showing a plume and then less
settled weather, while ECM introduces a cool NW'ly flow.

ECMWF: http://expert.weatheronline.co.uk/da...mwf/ecmwf.html
A ridge covers Scotland and Northern Ireland, leading to northerlies
elsewhere. The riedge moves slowly SE'wards at T+144, with little overall
change. By T+168 a trough moves down from the north as an upper ridge builds
towards Greenland. A ridge brings light winds for Englan and Wales, with
westerlies elsewhere.

The UK lies under WNW'lies due to a ridge to the west. The winds become
SW'lies at T+144 as a ridge extends over France and southern England.
