ECMWF: http://www.wetterzentrale.de/pics/Recm1201.gif
Westerlies cover the UK, with a ridge over the North Sea and a deep
Icelandic low. The low deepens and moves eastwards at T+144, bringing
westerly gales for all. The gales continue at T+168, as the low fills
slightly to the west of Norway.

MetO: http://www.wetterzentrale.de/pics/Rukm1201.html
The Met Office run places a deep low over the Faroes, leading to strong to
gale force westerlies over the UK. The winds become strong WNW'lies at T+144
as the low deepens and moves eastwards.

GFS: http://www.wetterzentrale.de/pics/Rtavn1081.gif
A weak ridge covers the UK, bringing westerlies and NW'lies. As with the ECM
run, westerly gales then move over the UK, with 850hPa temperatures ranging
from +1C over NW Scotland to +6C over NW Wales. The gales continue at T+144,
with a deep low to the north of Scotland, followed by slightly lighter
NW'lies and WNW'lies at T+168 as the low fills over southern Norway. A new
low to the NNW of Scotland brings strong WSW'lies for all on day 8, followed
by NW'lies and WNW'lies on day 9 as it moves eastwards and deepens. Day 10
sees strong NW'lies for all, with the deepening low now over Shetland and a
secondary low over the North Sea.

GEM: http://www.wetterzentrale.de/pics/Rgem1201.gif
The UK lies under westerlies from a weak ridge overhead. The winds become
westerly gales at T+120, with low pressure between Iceland and Scotland.
850hPa temperatures range from +3C over northern Scotland to +7C over
Cornwall. The gales continue at T+144, as the low deepens in situ.

JMA: http://www.wetterzentrale.de/pics/Rjma1201.html
The Japanese run shows a ridge over Ireland, with NW'lies for the UK. 850hPa
temperatures range from -7C over northern Scotland to -3C over Cornwall.
Strong northerlies cover much of the UK at T+144, due to a small low over
the North Sea. By T+168 the low moves away, leaving WNW'lies for all.

Model overlay charts (GEM/GFS/JMA):

The chart shows a weak ridge over the UK, bringing westerlies for most.

In summary, today's runs show that after the cold plunge this weekend, an
unsettled and windy spell is likely, with a good chance of strong to gale
force westerlies across the UK by Tuesday.
