I mean, I'm no expert but that evolution on the GFS is something that just doesn't happen...especially without a -NAO. I'd heavily favor the non-event the Euro shows at this juncture.

We develop a defacto west based -NAO though shortly after Xmas, so I wouldn't be shocked to see some blocky/wacky solutions between now and then.

 

Here's today's Euro between D8-11....you can see all those higher heights up in Canada expanding into the NAO domain....its not your classic NAO ridge back building from the Atlantic, but it may still offer some chances for storms provided the colder airmass gets trapped a bit underneath it

yeah discussed that earlier

it's an emerging/evolving aspect with the telecons.   the sources are differentiating toward more nao, run to run... while pancaking the pna.  

paraphrasing, it's actually the canonical transition from a -(wpo/epo)  +pna hemisphere.  when the pna griddles there's a lag correlation to the onset of nao. 

it really doesn't reduce your storm frequency - it just transitions the storm modes.

Reminds me more of a Nino December look with big height anomalies in Canada and near to lower then normal heights south of 39N or so.

Kind of the reverse for 2015 here. 93-94 was a record breaker here, and 2015 was a record breaker there. 

Well if you just look at Boston and metro west, 1993-94 was a major all timer.  Certainly in my top 3 experienced as is 2014-15 and probably 1960-61.   1995-96 goes to #4 due to the spectacular melts-lasting for weeks.

Oh I can understand that…was just responding to Rays post about 93-94.  93-94 and 95-96 were historic record breaking here. 14-15 was not record breaking here(it was very good), but not historic by a good margin. That one was eastern SNE- BOSTON’s record breaker.

93-94 was my first winter in Boston. Man were my expectations irreversibly distorted.

The potential and actual results of this December remind me of a Jerod Mayo pre-season quote I heard on WEEI this morning: "1000% percent... we have a lot of cap space... ready to burn some cash"
