My apologies for posting almost thrice in a row.
Next two weeks, week-averaged values of MSLP (with anomalies) and T2M anomaly according to the long-range CFS-v2 model. So let's put more stuff and make the model fail bad!

Week 1: There is a HP pattern relatively similar as past week (CAA-CAB-Greenland) although the blue color indicates that the highs weaken in average. Around this system, there is a ring of lows, especially close in Laptev and Alaska, that force similar circulation from America into the CAB and then toward the Barents sea. Strong wings over Beaufort coast continue for a few days according to ECMWF, but the CFS-v2 indicates that this pattern should gradually fade out, otherwise in average the map would not make sense.
Temperatures in Eastern Siberia, Alaska, and North Canada remain anomalously warm. I expect a big drop in snow cover this week in this areas, not just the following week.
For the DMI 80N lovers, it however may take some days for its anomaly to become positive again.
Week 2: The forecast of a high pressure dominating the basin is clear. However, how this plays later can differ a lot depending on the real positioning of the HP and its specific strength, if and how it couples with a low and in what direction...
In this case, the CFS-v2 predicts anomalously high temperatures practically all above the Arctic circle, (that is above lat N66 approx). Huge drop of snow cover overall. And I mean all, land and ice. Chilly in Europe and somewhere in the U.S.
Heck, I so much want to see this fail badly!!!!
