Wow just look at that tropical air coming our way later in the week! Has its
origin in the Caribbean with 564 DAM thickness and 10C 850s by the time it
reaches our shores. We are talking 14C plus in the south if it stays dry.
But that's the thing it will carry a lot of moisture and when this very warm
air comes up against much colder air over Scotland in the easterly off a
still bitter Scandinavia there is going to be copious amounts of rainfall,
bringing yet more flooding and misery. The question is how far north will
the warm air get. If shallow waves run fast eastwards then most of it will
stay in the Channel but it is likely that in the baroclinic zone one of the
ripples will be amplified and a deeper low will move across the UK
introducing clearer drier and colder air by Christmas day post cold front in
a westerly.
During this time the stratwarm mentioned by Mike Trigger begins to influence
the displacement of the Russian high eastwards and build pressure in the
high arctic/Greenland/Canada introducing a very cold northerly type, perhaps
in time for Boxing Day.
So the big weather story later this week will be the wet weather with
potential for floods (and gales), possibly mountain blizzards in Scotland if
cold air hangs on there. Also becoming very mild in the south, possibly
exceptionally so in a few places. As always we await the details from the
high res. models but there are some *ahem* interesting solutions emerging
already.
Exciting stuff.
Boring today, just mild with sunny spells and light winds. T+4.2C at 0900

Watch it Will, you mentioned the "COLD" word and "STRATWARM" Dawlish might be lurking!
Don't be silly.
