Here is a summary of the latest NWP output for 12z on Friday. Issued 0600z,
31/10/05.
The models show westerlies for all on Saturday. Beyond that there are signs
of a ridge affecting parts of the UK (especially for southern and eastern
areas) but the models differ greatly with its extent and strength. As ever,
more runs are needed.
ECMWF: http://217.160.75.104/pics/Recm1201.gif
A weak ridge covers the UK, with a low over the North Sea. Winds are SW'lies
over Northern Ireland and NW'lies elsewhere. The winds become SW'lies for
all at T+144 due to a deep low near Iceland, followed by southerlies and
SW'lies on day 7 as a weak ridge moves swiftly NE'wards over the UK.
MetO: http://217.160.75.104/pics/Rukm1201.gif
MetO also shows a ridge for the UK, this time with NW'lies for England and
Wales and SW'lies elsewhere. The ridge merges with a high over the Baltic
States at T+144 to bring easterlies across England and Wales. Scotland and
Northern Ireland lie under southerlies.
GFS: http://217.160.75.104/pics/Rtavn1201.gif
The UK lies under westerlies as the result of a weak ridge. Winds become
SW'lies for all at T+144 as a trough deepens to the west, followed by
westerlies and SW'lies as the trough crosses the UK on day 7.
GEM: http://217.160.75.104/pics/Rgem1201.gif
As with the other runs, a ridge is close to the UK. This time it's over
Ireland, resulting in westerlies for all.
GME/DWD:

Once again the UK lies under westerlies from a ridge, followed by WSW'lies
at T+144 as high pressure to the south moves ENE'wards.
JMA: http://217.160.75.104/pics/Rjma1201.gif
The Japanese run shows westerlies covering the UK with the British Isles
sandwiched between a high to the south and a trough to the north. The high
moves NE'wards at T+144 to bring westerlies and SW'lies for the UK.
NOGAPS: http://217.160.75.104/pics/Rngp1201.gif
NOGAPS shows westerlies for all at T+120, followed by light and variable
winds for England and Wales at T+144 as a ridge builds northwards. Scotland
and Northern Ireland lie under SW'lies.
KMA: http://www.kma.go.kr/kma03/gif/g21nh_smsr_120.gif
The Korean model shows a ridge to the west and WNW'lies for the UK.
MM5 snow forecast:

No snow is forecast to lie anywhere in the UK at T+120.
