Whilst I share many of this groups enthusiasm for a potential

sitting
over the Southwest for what seems for ever,could possibly migrate
north and
link up with that very illusory phenomenon 'the Siberian High' .
I've wracked my memory for any previous occurrences ,but can't
remember a single instance when that's happened before .

I can remember this happening. Have a look at the charts for the
first few days of February, 1991.

John,that High was not an Azores jobby ,it was largely over Europe,and
they
do move north at times. as that one did.....

Look at the charts for the first 3 days of that month and you'll see a
High not a million miles away from the Azores, which is the one that I
was referring to. It looks to me as though on the 4th it moves NE-wards
and gets absorbed into the High centred over the northern Baltic, though
other interpretations of the charts (I'm looking at those in "Weather
Log") are possible. You'd need charts at 6 hour rather than 24 hour
intervals to be sure.

Of course I'm not trying to claim that it was an exact (or even very
close) parallel with the current situation. Not only is the Atlantic
High much further north this time, it is also more intense than the one
in 1991 was.

Another example, although again not parallel, was in January
1985. On that occasion the Atlantic high got squeezed way
up north for a time, but it was always essentially an Atlantic
feature, before it dithered for a couple of days over the UK,
then was overwhelmed by rising pressure from the an
anticyclone which had extended across Scandinavia and the
Baltic from northern Russia.
