Default Today's model interpretation (25/04/06)

Here is a summary of the latest NWP output for noon on Friday. Issued 0541z,
25 Apr 06.

The models still show a settled weekend for many areas, but into next week a
trough will move in from the west with rain and stronger winds for all.

ECMWF: http://217.160.75.104/pics/Recm1201.gif
Northerlies cover the UK as the result of a low to the east and a ridge to
the west. By T+144 the UK lies under a col, with the exception of SE England
which is still affected by northerlies from a nearby low. It's all change at
T+168 as a trough sweeps in from the west, bringing strong southerlies and
SW'lies across most areas.

A weak ridge covers the UK, bringing NW'lies and westerlies as a result. The
winds become strong westerlies at T+144 as a trough moves eastwards.

GFS: http://217.160.75.104/pics/Rtavn1201.png
The UK lies under WSW'lies, with a weak ridge to the south. As with the
other runs, a trough moves eastwards at T+144, this time bringing NW'lies to
western Scotland and Northern Ireland, with SW'lies elsewhere. By T+168 a
deep low lies to the west with strong SW'lies.

GEM: http://meteocentre.com/models/glb00_120.html
A weak ridge covers the UK with WNW'lies as a result.

JMA: http://217.160.75.104/pics/Rjma1201.gif
JMA also shows a ridge over the UK, this time with a mixture of northerlies
and NNW'lies. By T+144 the winds become WSW'lies as a trough approaches from
the west.
