Winter never fails to deliver interest - a fantastic time of year for
meteorologists.

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

Mild at 4c Will? I call that benignly cold, or the cold side of cool.

Mild to me is 8c = Temp = 12C.

At that time of the morning 4C is mild!
Now at 1200 in the warm sunshine it is +8.3C and rising which is mild for
December up here.

Exciting stuff indeed Will ,stimulating as ever,I cannot recall however the
two features you mentioned ,very high temps in the south and arctic cold
come together in such a short period ,
Seems likely therefore only one will come off , I wonder which one you will
go for .......?
Happy Christmas anyway

In the south with very mild tropical air and arctic air in the north,
if the cold air pushes down over the country could it produce
thundersnow like 2004?

What, no shorts? When the dew point gets above 7C it is definitely
shorts weather. In fact, if there is no wind and I am feeling hardy, I
might shade it a few degrees below that.

Mind you, at only 8C - unless there is no wind - I would probably have a
"hoody" on over the T shirt...

It's always puzzled me how 7C can feel very cold in December or January
but I can go out in my shirt-sleeves at 6am in July and 7C feels just "fresh".
