30 mb U winds showing a peak of 35m/s on today's data at 60N. This is at the top end of analogues, but the general suggestion of this being focussed at 60N is a solid one.
Probable further strengthening of the polar westerlies in the Pacific and Atlantic in time looks on the cards, and the trend for the shift of the core of the PV towards west of Greenland dropping into Canada looks rock solid to me (as per October winter discussion and winter forecast).
Vraag van een ander
Does dropping the PV into Canda eventually teleconnect to allowing the ridge to build over Scandinavia?
Stewarts antwoord
eventually yes altough probably a bit too much inertia for it to fully develop until January.
