I think the Canadian is wrong for January with the loss of the blocking, but there should be a thaw, so maybe that skews things if its long enough and timed correctly.
Yea, I could see that....like 1987, which is also a good analog, but I select two week windows of time, so still would be a pretty good call from that lead time.
George, that was actually good analysis......very objective and level-headed....be skeptical of colder evolutions until the jet slows...all blocking does is prevent December 2015 and keep the warmth from being absolutely prohibitive to threats.
This is minor.... I'm talking maybe normal instead of +1 to +2, but blocking alone won't dramatically alter things because the PAC jet will be active until at least the later third of the month or so.
I never "abandon" or change the final outlook product....graded as is. However, the tone of the update is to simply imply a slightly cooler risk due to more blocking. But I also stated it will still be fairly mild until the PAC jet slows down. The most important note was the implication of this early blocking for later in the season.
Update on December and what it may entail for the rest of the winter.

Exactly....its like having the surface low near the BM, but the upper levels being elongated to over the Berkshires. You wouldn't disregard the upper levels in favor of the surface when forecasting synoptics, so why some are doing it with respect to ENSO in seasonal forecasting is beyond me.
