Hi Jon, although my confidence has plummeted to 25% given outputs over last 36
hours, the very cold air is not going to be far away, and on a global scale -
mighty close. The ingredients for a very cold spell are still there, I
note that
on the latest runs the cold air is less keen to spread south towards the
Balkans, and keener to spread west to north of Britain. What this
means I'm not
sure? A short let-up in the Atlantic vigour and that cold air will be
in like a
flash. Mind you if it is delayed then a cold Spring is more definitely on the
cards, which will not be good for lovers of short skirts :-)

I see that the 12:00 GFS ensemble has three members which bring the very
cold air into London in around a week's time, albeit only briefly in
each case. (Where by "very cold" I mean 850mb temperatures of -9C or
less. Another member bottoms out at about -5C.) Surprisingly, the
picture for Wick isn't that different.

Belay that. I don't know what I was looking at, but the chart has gone
now!
