I was wondering whether it anything to do with the high seeminly

staying further out in the Atlantic, hence a lot of cloud and drizzle
to
the east of the country!


Here's what I posted 29th June:
"I mentioned
the other day that I thought the SST anomaly would change by
the autumn to
one favoring zonality and the latest picture shows strong
warming
continuing south of 40N in the western N Atlantic

In theory, this should give us a more mobile westerly type with
deeper
than usual Atlantic depressions. The summer could get more westerly
and
be followed by a stormy autumn and a mild and stormy winter
also.
However, still far too early to firm up on anything as the SST
pattern
is still in the middle of a change and could easily develop
differently
to what I'm expecting."

Lately, I've seen signs that the type
may be changing from zonal to warm pool as the remains of last winter's
cold pool slips east. If that were correct, instead of a belt of lower
than average pressure lying W-E between Iceland and Scotland, the low
would be nearer the Norwegian Sea and there'd be a mid-Atlantic high
instead of a W_E belt of high pressure to the S of us. The UK would then
be in a bit more of a NW-ly instead of a W-ly.
