Here is a summary of the latest NWP output for noon on Friday. Issued 0544,
16 Jan 06.
The models show a prolonged spell of winds between south and west for the
UK, with low pressure to the north or NW and pressure remaining high to the
SE and south. This should bring a typical winter mix of sunshine and
showers, with weakening fronts bringing the lightest of the rain to southern
and eastern areas. As ever in a SW'ly setup temperatures will be on the mild
side. There are some very cold runs towards the end of the GFS as the high
persists to the NE and eventually brings in colder air, but as the other
runs show the high moving away long before then confidence is very low in
that evolution.
ECMWF:

Westerlies cover the UK with a low to the north and high pressure to the
south. The high moves NE'wards and builds at T+144, bringing SW'lies for
all. SW'lies persist at T+168 as the high moves slowly eastwards.

The UK lies under a westerly flow, again with a low to the north. A weak
ridge moves NE'wards over the North Sea at T+144, bringing southerlies and
SW'lies, folloed by more of the same at T+168.
