The new Adam is such a breath of fresh air...I wish Forky would take a break for a couple of months.

Looks like he just peaced-out.........I remember raindance was vocal about how he couldn't figure out how to delete his account last year, so Adam probably encountered the same issues. Hotel Amwx....y

1982-83 was a rough winter for the Dakotas regarding seasonal snowfall totals:

Grand Forks ND: 16.9" of snow (31.5" below normal)

Aberdeen SD: 18.9" of snow (23.8" below normal)

Fargo ND: 23.2" of snow (28.2" below normal)

Rapid City SD: 24.9" of snow (23.5" below normal)

Bismarck ND: 32.2" of snow (18.3" below normal)

International Falls MN: 46" of snow (26.9" below normal)

 

However, some other places across the upper Midwest ended up near normal to even well above normal like Duluth, Minneapolis, Marquette, other portions of Wisconsin and UP Michigan. So it's important to remember that, even on these maps showing a blazing red torch across the upper Midwest, it's all relative to normal and it can still snow there.

It always snows in the upper midwest and Lakes. The bigger issue in strong ninos for northern areas is ice thickness, snow retention, and potential abnormally dry weather patterns. Winter recreation is big in northern states, and warm nino winters put a damper on the norm....but it certainly snows.

Any cooler conditions in the Southeast will mostly be a function of all the clouds and rain keeping the high temperatures down. The eastward displaced Pacific vortex and the frequent jet extensions will flood North America with mild Pacific air. Those climatology packages beyond 15 days are defaulting to general El Niño climatology. This event is much more extreme than general El Niño climatology. 

1. A lot of it in the South is, indeed, from clouds limiting the high temps and rain leading to evaporative cooling. But there’s also dynamically induced cooling during storms due to the strong ST jet. I realize it isn’t modeling a “cold pattern” with Arctic air dominating, which I never said.

2. CWG referred to an EW H5 map at day 45 and in a blanket fashion said this was a “very warm” pattern. That same model’s 2m maps for weeks 4-6 are literally disagreeing with CWG’s “very warm” pattern. That’s what first got me to post about this. Most (S 2/3) of the U.S. is NN to BN on that model run!

3. Despite the typical climo of very strong El Niño, nothing is anywhere close to being certain especially for shorter periods within the winter. Even during very strong El Niños, there have been intervals of Arctic cold dominating though Jan/Feb have had them more frequently than Dec. For example at NYC:

-1/18-24/2016

-2/11-15/2016

-1/15-20/1992

-2/9-13/1992

-12/9-14/1982

-1/16-22/1983

-2/5-13/1983

-1/6-13/1973

-2/9-18/1973

-1/25-2/7/1966

-12/12-23/1888

-2/1889 very cold

-1/1-9/1878

-1/28-2/5/1878

 They may or they may not. That remains to be seen. There is no certainty about this. Yes, Nov 1-22 (weeks 1-3) is coming in warmer than was being shown earlier. But that doesn’t mean that weeks 4-6 (Nov 23-Dec 13) will definitely do the same.

 I’ll add that should the current SSW actually lead to colder, that wouldn’t per @Stormchaserchuck1be expected to happen for 30-35+ days afterward, which isn’t even til early to mid Dec (weeks 5-6 on the EW). OTOH, it often is warm in the E US near and for a couple of weeks after SSWs.

 This is a forecasting discussion, not a crystal ball discussion.

The Euro weeklies were absolutely bullied in this forum last winter for their expected inaccuracy past week 2 (they showed cold), but i have a feeling we will be seeing the same ones posting weeks 5 and 6 often this winter.

The big warm signal for this winter was beginning to be outlined as early as last spring when we were getting the first hints at how historic this super El Niño was going to become.

I agree that over shorter one week to 10 day periods throughout an entire 3 month winter season there can be some variation from the seasonal primary temperature departure pattern.

But the one shorter term temperature pattern that has become very reliable has been the warm up from around December 17th to 25th which has occurred every year since 2011 from Philly to NYC.

Many times the longer term models from early in December miss this warm up. So the closer to forecast time we get the models correct warmer.

A SPV disruption would not affect the troposphere that fast anyway. Usually 2-5 weeks...IF, IF, IF it downdwells into the troposphere. I have doubts of much affect. 

I agree with your post 100% except that I would substitute 4-6 weeks for your 2-5 weeks for this early in the season per @Stormchaserchuck1if it is going to occur. So, a map at 330 hours is irrelevant. Often the initial 3 week period is actually warm.

Absolutely savagely ruthless...I always dread seeing any optimistic prose from you because I know what the nature of the follow up point will be. :lol:

Pretty funny how this no snow winter is the one oddball year that didn't have a warm up at PHL.

What A FUCKING RIPOFF. Despite being a super hyper-awesome El Nino, we're in a ever-expanding drought. Models keep delaying the "sure to come" El Nino climatology in perpetuity. It's gonna be in September! No October! JK November! Nah it's actually gonna be December!  Screw off

There will be a lot of snow also in the higher elevations of the SE above 3500 feet. It snows in September here, we don’t need arctic air.

The wetness in Houston and other S areas in a very strong El Niño typically doesn’t get going reliably til sometime in November.
