Looking at the general flow above 60N there seems to have been a
pronounced and persistent easterly flow from northern Russia right
across to central northern Canada this month. It also seems as if the
Arctic ice pack is enlarging a little quicker than in previous seasons,
perhaps under the influence of more favourable conditions, with the
absence of large penetrations of warmer air.

What on earth are you talking about? Most of this years hurricanes have
headed north and not touched land until entering the Arctic.

The Greenland high has been very much in evidence as part of that setup.

Do you mean the Greenland Low or have I got my wires crossed?

Am I right in thinking that the jet across the Atlantic has also been further south?
At some point a disruption will doubtless occur, perhaps as early as next week if Will
is right - though IMHO I think the jury is still out. But if the lack of
penetration of warmer air to the north continues, perhaps there will be
a more potent blast when it comes?

According to my little red browser the weather is due to change for the
better as from today:
22nd October 05:14. What does early next week mean in this discussion?

This aught to be a dry, frosty week. But it is only the third or so
spell in which the lunar phases are in agreement or is it the fourth? I
was never much good at details.
