Default Today's model interpretation (10/01/06)

Here is a summary of the latest NWP output for noon on Saturday. Issued
0550, 10 Jan 06.

The models show a mobile setup for the weekend with a deep Icelandic low and
high pressure to the east. Troughs are likely to cross the UK and all areas
will see rain at some stage, heaviest in the west. The rain will be
accompanied by strong winds at times and temperatures will be on the mild
side of average in the main. Beyond the weekend there are no signs of a
change, with the ECM and GFS ensembles bullish about maintaining a mobile
flow over the UK. Indeed, the operational GFS decays the block to the east,
allowing the westerlies to blast all the way into Russia.

ECMWF: http://217.160.75.104/pics/Recm1201.gif
The UK lies between a low to the west and a high to the east, with SW'lies
for all. The low moves NE'wards at T+144, allowing a trough to cross the UK.
Ahead of the trough winds are SW'lies, with westerlies following behind. By
T+168 SW'lies once again cover the UK as a new low deepens to the NW.

MetO: http://217.160.75.104/pics/Rukm1201.gif
MetO shows strong to gale force SW'lies over the UK with a very deep low to
the NW. A trough crosses the UK during Sunday and by T+144 lighter SW'lies
affect the UK.

GFS: http://217.160.75.104/pics/Rtavn1201.png
GFS shows southerlies and SSW'lies, this time with a low to the west. The
low fills to the north of Scotland at T+144 withw esterlies and SW'lies as a
result for the UK.

The German run shows very similar setup to GEM, with a trough to the west
and SW'lies for the UK. The trough crosses the UK at T+144, bringing light
winds for all.

JMA: http://217.160.75.104/pics/Rjma1201.gif
The Japanese run shows WSW'lies and a trough to the east. Winds become
SW'lies and southerlies for England and Wales at T+144 as a low deepens over
Ireland. Elsewhere winds are SE'lies.

The UK lies under southerlies with a trough to the west.

The Korean run brings low pressure close to the NW of the UK; this leads to
SSW'lies for all.
