Here is a summary of the latest NWP output for noon (GMT) on Wednesday. Issued 0512z, 11/08/12.

ECMWF: http://www.wetterzentrale.de/pics/Recm1201.gif
ESE'lies cover the UK due to a low to the WSW. A trough moves swiftly NE'wards on day 6, leading to southerlies, followed by westerlies for most on day 7 as the parent low moves over Scotland. Day 8 sees westerlies for most as the low continues moving NE'wards, followed by southerlies and SE'lies on day 9 from the next low. That low moves NE'wards too on day 10, leaving WSW'lies across most areas.

MetO: http://www.wetterzentrale.de/pics/Rukm1201.gif
The MetO run brings easterlies for most as the result of a trough over southern areas of England. The trough moves northwards on day 6, introducing SW'lies for most.

Low pressure lies to the SW and a trough covers England and Wales. To the north there are strong easterlies. The low and associated trough move northwards on day 6, leading to ESE'lies for the Highlands northwards and to SW'lies elsewhere. There are southerlies on day 7, followed by more of the same on day 8; low pressure remains to the west on both days. Day 9 sees the low move NE'wards, drawing SW'lies across the UK. On day 10 a trough moves eastwards, with WSW'lies in advance and WNW'lies following behind.

GEM: http://www.wetterzentrale.de/pics/Rgem1201.gif
GEM shows SE'lies with a low to the west.

JMA: http://www.wetterzentrale.de/pics/Rjma1201.gif
The Japanese run also shows SE'lies.

In summary, the latter half of the working week will see a trough move NE'wards across the UK, with widespread rain. Temperatures will be close to average, perhaps a little below in the northwest and a little above in the far SE.
