High pressure (1025mb) lies over the Azores, with another high
(1030mb) over Scandinavia. Low pressure (1000mb) lies over Western
Russia and Southeastern Europe, with another low (970mb) well to the
west of the UK in the Atlantic. Winds across the country are moderate
southwesterlies in the northwest, but light elsewhere and variable in
direction. Most areas will be rather cloudy, with rain at times
towards the northwest. Temperatures will be close to normal in most
parts. Beyond this pressure builds strongly to the northeast and tries
to ridge southwest towards the UK, but most of the country sees rather
more unsettled conditions trying to move in from the Atlantic with the
south and east staying mainly dry.

strongly to the northeast and tries to ridge towards the UK, but mild
Atlantic air moves in across the UK with most of the unsettled

Summary:
The models continue to indicate that most parts will be mostly mild
next week, with most of the unsettled weather towards the northwest of
Britain. However, pressure rising to the northeast needs watching, and
may introduce some colder air to eastern parts, as indicated by the
T+144 GFS chart ( http://www.wetterzentrale.com/pics/Rtavn1445.html ).

Also, a special mention to the T+192 JMA chart. It almost certainly
won't happen, but just imagine if it did...! (
