Sometimes he does deserve some credit though. He has been using this experimental hurricane ace analog technique since about late Summer and it's been pretty accurate so far. It showed a warm October for most of the country with it being a little cooler in the west(that turned out good). It showed a cold eastern half of the country for November. The month isn't over yet but it's going to at least have the right idea. It says December will also be colder than normal from the plains eastward. This goes against a typical Nina look so it will be interesting to see how that works out. Then, it shows a big flip later in January into February with the cold being centered more over the west with a fairly big SE ridge. The cold then comes back east for March. I have to say I'm kind of intrigued by this since the first couple of months seem to have been quite accurate and although there have been some swings in the medium range look from the models(which is typical)there still seems to be the general consensus of eventually leaning toward a +PNA pattern setting up which also favors his analog method for December.

I've seen other outlooks going with that type of progression for DJFM as well.  If so, the Midwest could sort of be a sweet spot whether it's with clippers or southwest lows but with the risk of thaws increasing beyond the new year.

The worst :axe:

The last good March we had was in 2012. Every March since then has been god awful (with the exception of 2016 perhaps).

About 2/3 of the way through the month. The colder than average anomalies in the Midwest will likely get eaten into in the coming days, but should still finish colder than average for the most part.  Compared to the last couple Novembers, it's a better look for winter wx fans.  Though the cold has not penetrated into the deep South as effectively as 2013/2014 on the monthly scale, the past 2 weeks have even seen that region be colder than average.

This isn't a bad look at all at the end of the 12z European ensemble today. Nice high amplitude ridging/-EPO on the Pacific side and looks like -NAO/-AO too. Also appears to be hinting back to -PNA with southwestern troughing and southeastern ridging. If that verified, could be an active period with good cold into the source region likely due to the -EPO.eed65bdb354d935975826acc7c7830fe.jpg

Great post!

The AAM is projected to tank over the next few weeks and with the increase in trade winds expected later on this month towards early December, I foresee a return to the La Nina pattern we saw earlier this month as the Pacific reshuffles beyond December 6th. One thing to keep in mind, in relation to the image above, is the shift in the PV from Canada to Europe, which would favour upward wave activity in the stratosphere. However, the next 2 weeks look really tranquil and somewhat boring for much of the consensus.

Good points. However, I think that media outlets such as accuweather, weatherbell and, here in Canada, The Weather Network need to hype the idea of this upcoming winter being a blockbuster one in order to draw viewers and subscribers. Think about it: if they predicted a tame winter, not as many people would tune in or subscribe. The Weather Network in Canada is calling for a "return to traditional Canadian winter conditions" as well as "the winters of our youth", which is a joke as it all depends on when your youth was. If your youth encompassed a period from the mid 60s to mid 80s then, yes, they were more often than not, very cold and snowy. If, on the other hand, your youth was in the early 50s, then for this winter to be like those ones, it would have to be mild.

 Environment Canada and the National Weather Service, by contrast, are government funded and thus do not need to rely on subscribers and viewers wanting big storms to follow. Hence, there is less hype. I've heard that Environment Canada is far less bullish on this upcoming winter and I gather the NWS is as well.

The first 10 days of December look very boring.

New Euro monthly for January. Nice Niña look if it pans out. FWIW, the Euro monthly for December issued back in November did a pretty good job with the western ridge eastern trough look and generally drier than average precip anomalies. Here's hoping for a better January after a hopefully better close to December. 5050b3050749a2eca5af8b2969f8bbd6.jpg&key=19012a97a354b78848f5a19d454b4558253fb423ab4444d0b89b7eaa6bfd331404e35a841a0dcdbeda1144054ea281b5.jpg&key=7e6fae26616dbf37fa0d25f53b9792c6a2dcee1af203c078ae43c891cb4a569c

I wouldn't have said what he did but I think it's an important reminder that ENSO effects on the US aren't always what you envision and that the "most likely" outcome doesn't always pan out. Sometimes I'm guilty of it myself too, during the times that I do try to get into seasonal stuff.

Weak ENSOs in either direction tend to be prone to toss ups. But to say you are done with ENSO is like saying you are done with gravity.

True, but this Nina was organized enough that it's a bit surprising (to me anyway) how things have turned out so far.
