Default Today's model interpretation (20/08/09)

Here is a summary of the latest NWP output for noon (GMT) on Tuesday. Issued
0453z, 28th August 2009.

The middle of next week will see SW'lies across the UK and the NW/SE split
will continue; the majority of the rain will be in the north and west.

ECMWF: http://www.wzkarten.de/pics/Recm1201.gif
A slack low lies to the WNW, leading to SW'lies. SW'lies persist on day 6
and on day 7 they strengthen as a low deepens to the WNW.

MetO: http://www.wzkarten.de/pics/Rukm1201.gif
The UK lies under SW'lies, with a low to the north and a trough to the west.
There's little change on day 6.

GFS: http://www.wzkarten.de/pics/Rtavn1201.png
SW'lies cover the UK, with complex low pressure to the NW and north. Strong
to gale SSW'lies move over the UK on day 6 as a trough approaches from the
west and on day 7 the winds become westerlies for all as the trough moves
away to the east.
