Ensembles rarely have huge 12 or 24 hr shifts in the long range. They are usually gradual. Still shows an Aleutian ridge, GOA trough, and a -NAO. Out of those 3 factors...2 are favorable. The GOA low is not, but hopefully the other two can try to overwhelm that. I think that it's also important to note that we are in early December at this point....climo could still use a couple of weeks of cooling...but we'll take what we can get. I think if this pattern were later in the month, we'd all be money in the bank.

To be honest Scott, you and me both know that a -NAO isn't the best pattern for my neck of the woods (except in the snowbelts) In Dec 2010 London had nearly a metre of LES due to the -NAO. So maybe I have to rely on clippers.

It seems to me that the goa low wants to migrate further south into an EPO position. What do you think? It appears with a throng enough Aleutian ridge it can get pushed around a little. Pattern night and day vs a year ago and sensible wx this month following suit.

I bet if you correlate Toronto snow totals annually to NAO you'd find out your perception is wrong.

You don't want a +NAO for YYZ. If you have a some sort of a trough out west with a -NAO, that probably means lows coming up through the Ohio valley and even if they redevelop...the primary low will give you snow. Like everything, there can be too much or too little of a good thing. I find it hard to believe a modest -NAO would be bad for YYZ.

Well I guess it can't be that bad but it has to be primarily an east-based block for those miller B's to bring us good snow. A +NAO like last winter was horrible but then again wasn't 2007-08 mostly a +NAO. We had 90'' that winterthumbsupsmileyanim.gif

Yeah that retrogression is hinted at on the euro ensembles and even on the GEFS. It may being try to fit the week 3 depiction on the weeklies. Since it is just occurring at the tail end of the ensembles, it's tough to say whether that is a hiccup or a legit trend. If the tropical cionvection decides to move towards P1 or P2, then perhaps it's legit.

Well, see the Pacific. You want some sort of ridge near AK or Aleutians. That made all the difference.

I'm not analyzing too in depth, I just noticed that the string of negative anomalies on the GFS have been replaced with very positive ones.

Well let me say again, we may yo-yo for a time into early December. As December roles in, I don't think we'll have continuous frigid temps since climo is barely wintry at this point. We also still fight the PAC jet which may keep the "coldest" weather into Canada, but I would expect chunks of it to break off if the pattern modeled comes true, and the overall looks is below normal as of now.

With the -NAO we still may be having a gradient pattern across the northeast given how the west looks.

I think he wants -NAO, too.
