Here is a summary of the latest NWP output for noon on Tuesday. Issued
0625z, 5 January 2007.

Zonality continues for the forseeable future. Conditions will be largely
unsettled with gales or severe gales in places - mostly, but not
exclusively, in northern and western areas.

ECMWF: http://expert.weatheronline.co.uk/da...mwf/ecmwf.html
A deep low is centred over the Western Isles, leading to strong SW'lies for
the majority. A weak ridge moves swiftly eastwards on day 6, leading to
westerlies and NW'lies, followed by further westerlies on day 7 from a low
to the north.

MetO: http://expert.weatheronline.co.uk/da...ukmo/pslv.html
Strong WSW'lies cover the UK with complex low pressure to the north and
northeast. Day 6 sees a ridge move across the North Sea, with SW'lies ahead
of a trough for the UK.

GFS: http://expert.weatheronline.co.uk/pslv_frame.htm
Strong to gale force westerlies cover the UK, which lies under the effects
of a low to the north and a ridge to the west. A new low moves eastwards on
day 6, bringing further strong to gale force westerlies. By day 7 another
weak ridge lies to the east, with strong NW'lies for the UK.

GEM: http://expert.weatheronline.co.uk/da.../gem/pslv.html
The Canadian brings SW'lies across much of the UK in association with a deep
low to the west.

The Japanese run shows strong to gale force SW'lies over the UK, this time
with a low to the NW.

NOGAPS: http://85.214.49.20/pics/Rngp1201.gif
Complex low pressure dominates the UK, with centres west of Scotland, over
the North Sea and to the NE. Winds are a mixture of westerlies and WNW'lies
as a result.
