Here is a summary of the latest NWP output for noon on Wednesday. Issued
0550, 25 Feb 06.

The models show an unusual event looming next week, with low pressure
encroaching on the UK and some very cold air involved. It's likely some
places will see significant snow as Atlantic lows bump into the cold air and
slide eastwards, but it's too far away to say with any certainty which areas
will be affected. It's likely that milder air will work its way northwards,
but given the way the MetO and GFS runs are today it could be a slow
process, taking a few days to reach Scotland.

ECMWF: http://217.160.75.104/pics/Recm1201.gif
Complex low pressure lies to the NE, leading to NW'lies for most. A trough
moves over the UK at T+144, with cold westerlies for England and Wales and
NW'lies elsewhere. NW'lies cover the whole of the UK at T+168 as low
pressure fills over Denmark.

MetO: http://217.160.75.104/pics/Rukm1201.gif
As with ECM, complex low pressure covers Scandinavia, with cold NW'lies and
NNW'lies as a result. One of the low centres moves over the North Sea at
T+144, with further NNW'lies and NW'lies.

GFS: http://217.160.75.104/pics/Rtavn1201.png
The UK lies under a large upper cold pool, with lows to the NE and WSW.
Winds are a mixture of westerlies and WNW'lies for most, followed by light
winds at T+144 as one of the lows moves swiftly eastwards along the English
Channel. Another low moves along the Channel at T+168, with a mix of
easterlies and NE'lies for the UK.

Westerlies cover the UK with low pressure to the NE and a ridge to the
south.

Westerlies and NW'lies cover much of the UK, with lows to the NE and WSW,
much as with MetO. The latter moves ESE'wards over Biscay at T+144, leaving
the UK under NW'lies.

As with the other runs, a mixture of NW'lies and NNW'lies is affecting the
UK, this time with a low to the south of Norway.

The Korean run shows a small high to the SW and NW'lies for all.
