Some nice 24 hour trends in the ensembles. Basically, the theme has been a more -epo type look. Heights have been depicted to be much higher than even 36 hrs ago, which in turn aids in cross polar flow into Canada. The euro ensembles still tried to dig the trough in the high plains around 12/3, threatening a cutter, but even they started out with a more -epo look. I still think a warm solution is very possible for the storm around 12/5, but it looks to try and continue the "step down" process afterwards. The nao block continues to hang the whole time as well.

Give Dec a chance. The odds might be a little less down here, as compared to sne...but folks we are very early into the season. I think people feel that December may be the only wintry month and want it to start snowing immediately, but I wouldn't take that theory to the bank just yet.

Good post...it's going to happen eventually, it's just a matter of when. The -EPO would certainly be of tremendous importance in getting the ball rolling faster. As it is, with the ensembles still not totally sold on the big west based -NAO block (seems like the one that appeared for days has become fantasy now), it may take a while, including a few cutters, to get this pattern flipped.

There's still plenty of time, some signs are encouraging at this point. I do still think most areas north of PHL cash in at least one major snowstorm before December is over. We shall see.

Greg,

I wish I could find a better graph, but just eyeballing a couple at the EMC site, my interpretation would be that the upgrade has not shown that much of an improvement, while the gfs has improved since its upgrade. There were some shaky solutions the Euro had this autumn (too far e with the tropical flooding rains, had a lakes cutter when the low went east of us among some), The graph is interesting as when the models go bad, they do tend to go bad in tandem.

Best post on this subject!

12z GFS looks really cold in the long range. It develops a nice -EPO towards the end of the run. Our storm for December went through the lakes on the run .

Primary goes negative to quick and with a flat PNA I doubt that this would happen. The ensembles should have it more south and east.

Been cold in the long range for 10 days now.....means nothing. I'd rather have the cold/storms in mid to late December anyways

when we have a better climatological chance of it snowing and better white X-mas chances.

It's just going to come down to whether we can get the Pacific to cooperate for a time during these storm threats. It's too early in the season to have otherwise (it's too early in the season in general). The Atlantic looks solid over the next couple weeks even if it's not in the form of a severe retrograding Greenland block. I'm not going to speculate far into storm tracks on the models day 10 and beyond, hopefully some of the hints of a spike in the PNA or a dip in the EPO are not just fantasy this go around.

Question...Most people say we need to get our snow in december, as the pattern is going to suck after. Well i know its early but it seems like the pattern pretty much sucks now, how worse can it can in january?

50's and 60's with :raining: . A lot of people think that January will be ****ty. LC and a few other people think it's not going to be ****ty.

A couple of winters ago had a crappy December but a pretty decent end of January/beginning of Feb. That was a Nina winter but did not play out as a traditional Nina winter per climo.
