Gibbs has cancelled Dec now after his initial forecast had it very cold. He's close to pulling plug on entire winter

Very cold December forecasts were always in trouble IMHO. My initial mild forecast had it +4 and today I'd say probably normal biased with a +5 first 10 days and a much colder last 20.

I guess people don't remember that +1 Decembers can produce double the amount of snow.

A normal or +1 Dec would be welcomed. That's what I want since it would be snowy. Problem is with Canada absolutely torched with warmth there is not even normal cold..there'll be no snowcover over much of Canada..it's just a sickening feeling for me right now

I feel fine with mine so far:

The start of the month looks generally warm and dry for much of the nation, outside the Northwest where disturbances will amplify downstream of Pacific ridging. Stormier weather will be introduced into the eastern half of the nation for the second half of the month, with colder air reaching the Plains.

Where's the credible evidence regarding Canada? Post it? Sorry.....long range 3-4 week forecast which often flip a week later don't constitute credible to me unless you can supply some verification scores.

You've done a good job of worrying weenies, but the joke is over.

Jerry, do you have a link to that map of temp departures across Canada when we were following your "elephant"? Kevin, though psychologically unstable, does have a point about the airmass over Canada for the next few weeks, and I think it would be good to monitor.

I'm not out to worry weiners..I'm letting my feelings/thoughts be known. I am 110% legitimately worried.

You know who I think also is, but would never come out and admit it is Will

Hey it's on the back of my mind....probably his too, but I've seen sh*t switch around so quickly in December. I guess at this stage of the game...and probably many others feel this way..it's way too early to worry about the WHOLE month of December.

If we continue to see a mega trough hang out by AK with a +NAO in the next 2-3 weeks..then maybe we revisit this. How quickly we forget about torch cutters at the beginning of December.

The AAM is sliding back down again, solidifying the RNA. Usually, this whole thing retrogrades and that will put the trough back along the East Coast again as we enter December.

It is going to take a ridiculous +EPO / Alaskan PV to keep the NAO from going deeply negative which is what the models are showing in the extended. Once this feature retrogrades and the ridge comes back across the Rockies, we may get a late-October styled +h5 anomaly again.

I am still impressed with the pattern basically now through the next 7 days. This is a very 1955-like picture with a deep NAO pattern and a transpolar ridge.

CPC charts are close to ludicrous in terms of NAO state.

I'm not a met. but do think a 1993 could be pulled out of the hat. Much of that December wasa torch, but then look what happened right around christmas. Maybe this will be the year Lake Ontario freezes over.

November 1955 was below normal up in Ontario though, wasn't it?

From 2 years ago? Maybe this?

What are your thoughts about the PAC jet breaking thru in the extended and torching Canada ala 2000-2001?

I said it is Nov 55-like with the transpolar ridge from the NAO regions. I am not accounting for sensible weather, especially in 1 specific location.

But for the next 5-7 days, it is going to resemble 1955 and then between the 20th-25th it will look like 2001 more while the EPO is screaming positive.

The good news is: the state of the stratosphere isn't anything like 2001.
