Note: As usual during the summer half of the year I'll soon be off to the
wolves, hence the shorter then normal analysis.

Here is a summary of the latest NWP output for noon on Saturday. Issued
0458z, 21st October 2007.

In summary, there are signs of a change today. It's likely the end of the
week will see a trough disrupt over the UK, bringing an unsettled spell
across the UK.

ECMWF: http://expert.weatheronline.co.uk/da...mwf/ecmwf.html
A large high lies to the NE, with a ridge over the UK. Winds are SE'lies for
Scotland and Northern Ireland, with NE'lies elsewhere. On day 6 a trough
deepens to the west, introducing southerlies for most. By day 7 a secondary
low crosses Ireland, with southerly gales over the UK.

MetO: http://expert.weatheronline.co.uk/da...ukmo/pslv.html
MetO shows an elongated high over southern Scandinavia, with NE'lies for
much of the UK as a result. On day 6 the high builds and drifts westwards,
maintaining NE'lies over the UK.

GFS: http://expert.weatheronline.co.uk/pslv_frame.htm
A deep low covers Iceland, leading to SW'lies over Scotland and Northern
Ireland. Elsewhere a ridge brings light winds. On day 6 a trough moves
eastwards over Ireland, with southerlies in advance. Day 7 sees the trough
move over England and Wales. There are SSE'lies in advance and westerlies
following behind.

The Canadian run brings easterlies and SE'lies to the UK, with a large high
to the NE.

JMA: http://85.214.49.20/pics/Rjma1201.gif
JMA is similar to GEM, with a ridge over the UK from a high to the NE. Winds
are ENE'lies for England and Wales, with SE'lies for Scotland.
