Default Today's model interpretation (21/10/06)

Here is a summary of the latest NWP output for noon on Wednesday. Issued
0510z, 21 October 2006.
**NB - There won't be an analysis issued tomorrow as I'll be staying
overnight near the wolf centre**

The outlook remains generally unsettled for the latter half of the working
week, although there are signs of high pressure settling things down for the
weekend. Despite double-digit minima being forecast via GFS, temperatures
would be a fair bit lower under clear skies and low winds - possibly cold
enough for a touch of ground frost in sheltered areas.

ECMWF: http://85.214.49.20/pics/Recm1201.gif
Southern England lies under easterlies from a low to the SW, while a trough
to the WNW brings westerlies to northern Scotland. Elsewhere, winds are
light due to a col. A mixture of northerlies and NW'lies covers the UK at
T+144 as a ridge moves eastwards. By day 7 winds are light across the UK due
to a high over Ireland.

MetO: http://85.214.49.20/pics/Rukm1201.gif
The MetO run shows a trough over Ireland, leading to SE'lies across the UK.
A ridge builds to the west at T+144 and this brings a complete change in the
wind direction, with NW'lies across the UK instead.

GFS: http://expert.weatheronline.co.uk/pslv_frame.htm
Brisk easterlies cover the UK, with low pressure to the SW. A ridge builds
at T+144, resulting in light winds for Scotland with easterlies elsewhere.
By day 7 winds fall light across the UK due to a ridge.

GEM: http://meteocentre.com/models/glb00_120.html
Unavailable at time of issue.

JMA: http://85.214.49.20/pics/Rjma1201.gif
The Japanese run shows a low over Biscay and a mixture of ENE'lies and
NE'lies as a result.

NOGAPS: http://85.214.49.20/pics/Rngp1201.gif
A col covers the UK with light winds for most. The exception is northern
Scotland, which lies under northerlies from complex low pressure to the NE.
