Default Today's model interpretation (19/02/09)

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

Here is a summary of the latest NWP output for noon (GMT) on Monday. Issued
0520, 19th February 2009.

Early next week will see the Azores High affecting the UK, bringing largely
dry but probably cloudy conditions to much of England and Wales, with
drizzle or rain likely further north. Temperatures will be at or above
average generally, although patchy frost is possible should skies clear
under the ridge.

ECMWF: http://expert.weatheronline.co.uk/da...mwf/ecmwf.html
ECM has WNW'lies with a ridge to the west and a low over southern Sweden.
Winds become westerlies on day 6 as the ridge declines and moves eastwards.
On day 7 NW'lies and WNW'lies cover the UK as pressure builds to the west.

MetO: http://expert.weatheronline.co.uk/da...ukmo/pslv.html
The Met Office model shows westerlies for all with the UK under a ridge. On
day 6 SW'lies affect the UK as low pressure deepens to the north.

GFS: http://expert.weatheronline.co.uk/pslv_frame.htm
A ridge covers the UK, with light winds for all. The ridge becomes a high
over the Channel on day 6, leading to WSW'lies for the UK. WSW'lies persist
on day 7 as the high moves eastwards.

GEM: http://expert.weatheronline.co.uk/da.../gem/pslv.html
The Canadian run shows WNW'lies with a ridge to the west.

JMA: http://85.214.49.20/pics/Rjma1201.gif
The Japanese model shows the same setup as GEM, with WNW'lies for all.
