Here is a summary of the latest NWP output for noon on Thursday. Issued
0542, 15 Jan 06.
The runs continue to show a changable setup for the UK with weakening
troughs crossing the British Isles, interspersed with brief ridges. As usual
it'll be driest in the south and east, windiest in the west. Temperatures
look like being average to above average in the main, with the really cold
air staying to the east.

Strong WSW'lies cover the UK due to a deep low to the NW. A trough moves
swiftly eastwards at T+144, leaving the UK under westerlies. By T+168 winds
become WSW'lies again as the result of a weak ridge over the North Sea.

to the SE and complex low pressure to the NW.

GFS shows a trough to the west and a mixture of westerlies and SW'lies for
the UK. The trough weakens over the North Sea at T+144, leading to
anticyclonic NW'lies and westerlies for the UK. By T+168 pressure rises over
France, resulting in WSW'lies for all.
