==============================

If Will had said anything about the UK "tapping into cold" there might
be the germ of a point here; but he didn't. He identified that the
anomalously cold air in and around Greenland is reinforcing the
baroclinicity that is maintaining zonality and giving us chilly flows
from the westerly quarter. I'd only mildly debate "very cold" rather
than "cold" for Scotland (with, as he says, milder interludes).

He further speculated as to whether -- or not -- there is a
possibility of strong Atlantic ridging, the first signs of which may
be identified from the Pacific via amplified Canadian troughing. This
is something that we all as forecasters are looking at. Apologies to
everyone else for feeling the need to re-iterate this.

My own speculative thoughts are that we may see ridging rather closer
to the UK in the extended medium range (through mid-month), so perhaps
becoming a little less cold for a while (fluctuating to average near a
little above normal nationally) after the upcoming coldness. Then,
even more speculatively, maybe colder again end of December with
ridging farther west.

I have to say that these cold and showery westerly types, while
interesting, are often particularly challenging and difficult for
certain industry sectors. Anyone who has forecast for winter roads
would probably agree.
