Default Today's model interpretation (13/10/08)

Note: I've to leave early today - hence this is a shorter analysis. Normal
service will be resumed tomorrow morning.

Here is a summary of the latest NWP output for noon (GMT) on Friday. Issued
0454z, 13th October 2008.

The end of the week still looks changeable with a series of weak ridges and
troughs. The most likely time for the latter is Saturday, with all areas
seeing rain.

ECMWF: http://85.214.49.20/wz/pics/Recm1201.gif
A weak ridge covers southern England, with WSW'lies elsewhere. On day 6 a
trough moves eastwards, with further WSW'lies. Day 7 sees a weak ridge with
light winds.

MetO: http://expert.weatheronline.co.uk/da...ukmo/pslv.html
MetO shows SW'lies for all with a trough to the west. The trough crosses the
UK on day 6, with NW'lies in its wake.

GFS: http://85.214.49.20/wz/pics/Rtavn1201.png
WSW'lies cover the UK, due to a weak trough. A weak ridge brings further
WSW'lies on day 6 and day 7 sees strong to gale force WSW'lies as a low
deepens to the north.

GEM: http://expert.weatheronline.co.uk/da.../gem/pslv.html
The Canadian run shows WSW'lies for all, again due to a weak trough.

JMA: http://85.214.49.20/pics/Rjma1201.gif
The Japanese run brings SW'lies for Northern Ireland and Scotland, with a
ridge and lighter winds elsewhere.
