Last winter, the Arctic and North Atlantic Oscillations remained in the high, positive range for an unusually long time, This overwhelmed any impact from La Nina and kept the Arctic air trapped in the far north while mild, Pacific air overwhelmed the country much of the season.

The odds of this happening again this winter seem low based on what we have been looking at.

My thoughts.

Also, NW Canada looks much colder than last year, and looks to be slightly colder than seasonal norms. This will have an impact on the weather downstream into the US. Also sea ice in the Arctic is low and there are warmer than normal SST's in the Arctic. This could have a significant on the AO and what it does this winter.

First flakes near Halloween on the 18z GFS

This is definitely going to happen. :lol:

In all seriousness though, the GFS has been fairly consistent in the long range to bring significant chilly air to our region after the mid range warm spell. It's ensembles agree with such an idea. The chilly air would be quite the contrast to the mid range warm spell if it were to verify as depicted by the GFS.

This may be a dumb question but if all of this blocking is snowing up in the mid to longterm why would have temps in the 70's mext week????

Our weather here in the Northeast is more strongly correlated to the Pacific than the Atlantic at this time of year, so the blocking is somewhat muted. This changes as we head into winter, with the NAO exerting more influence. I actually wrote a post in large part on your question today.

Maybe I didn't use the best choice of wording, I'm doing these post pretty quick. I remember hearing at a conference than some models including the GFS are actually too cool, not by much, only a margin of a degree C. Considering that this warm spell is still a long ways away, things could change.

Looks good to me. Normal and just about normal December and January. Forget February. You're not seriously worried about what the CFS is saying are you?

Snow88 is the resident model hugger, lives and dies on a model run! Lol. But seriously the CFS really isnt the best model for longer range forecasting by any stretch of the imagination
