Default Today's model interpretation (29/10/04)

Here is a summary of the latest NWP output for noon (GMT) on Tuesday. Issued
0604z, 29/10/04.

The mainstream models are pointing to a mostly settled outlook for the
middle of next week, although it remains to be seen whether the high is a
cloudy one or not.

ECMWF: http://64.246.48.81/pics/Recm1201.gif
High pressure is centred over the Baltic, with a ridge acorss the UK
bringing westerlies for Scotland and ENE'lies for England and Wales. By
T+144 a high builds to the west of the UK, bringing NW'lies and NNE'lies.
The high builds in situ at T+168 with NE'lies and northerlies.

MetO: http://www.wetterzentrale.de/pics/Rukm1201.html
England and Wales lie under a ridge, with SW'lies elsewhere. The ridge
builds over the UK at T+144 with westerlies for northern areas and
easterlies for southern areas.

GFS: http://64.246.48.81/pics/Rtavn1201.gif
The UK lies under high pressure, with light anticyclonic winds. 850hPa
temperatures vary from freezing over southern England to +6C over Scotland
and Northern Ireland. The high builds over the UK at T+144 and then stays
put all the way out to day 10 - although by then westerlies are affecting
northern Scotland.

NOGAPS: http://www.wetterzentrale.de/pics/ng...20.europeg.gif
Light winds cover the UK due to high pressure centred over the British
Isles.

GEM: http://www.meteocentre.com/models/glb00_120.html
The Canadian run shows a ridge from the east over the UK, bringing
easterlies and southerlies. The ridge sinks southwards at T+144, introducing
westerlies for all.

JMA: http://www.wetterzentrale.de/pics/Rjma1201.html
The UK lies under SW'lies due to a ridge over southern England. The ridge
builds at T+144, bringing light winds for Wales and much of England. The
winds become westerlies and northerlies on day 7 as the high recentred to
the south of Ireland, followed by easterlies on day 8 with a high north of
Scotland.

KMA: http://www.kma.go.kr/kma03/gif/g21nh_smsr_120.gif
Low pressure is centred to the north of the UK, leading to westerlies for
all.

DWD: http://www.wetter.com/home/img/sat/g...290000_120.gif
The UK lies under light easterlies and SW'lies due to a ridge from the east.

GM CPTEC: http://www.cptec.inpe.br/prevnum/Global126_sx6_Gl.shtml
Strong SW'lies cover the UK, with low pressure to the north and a ridge over
East Anglia.

MM5: http://rain.mmm.ucar.edu/mm5/plots/n...6hrn.hr120.gif
As with the Brazilian run, the UK lies under SW'lies with high pressure over
France.

MM5 Snow forecast:
