Yeah, I did it already!

Super El Nino coming

[Upstate Tiger]

So we have officially entered El Niño phase.  Most agree it will be strong and possibly super El Niño.  
 

The strongest El Niño on record was the super El Niño of 1877/1878.  It actually started in late 1876 and was fully established in spring 1877.  
 

The winter of 1877/1878 was known as the year without winter, especially in the Midwest and eastern US.  Farmers actually planted in February.  
 

This El Niño is starting a little later and no two are the same but at this point, an above average temp winter would be a good bet.

 In the Midwest it was, indeed, quite mild. But in the NE, it averaged only moderately AN with Dec AN but Jan-Feb pretty close to normal. Jan actually was slightly BN in some cases like at NYC.

 In the SE, only Dec was a mild month. Jan was slightly to moderately BN and Feb was not too far from normal. Thus DJF averaged only slightly AN to NN in the SE.

SE example for DJF 

Asheville: 43.6, 35.2, 39.8

Jan was 35.2/BN with 8.5” of SN (double the normal) from two ~4” snowstorms. The coldest was 7F.

Knoxville was similar. Savannah also had a BN Jan.

Hopefully not another 97/98 that was warm and had lots of severe weather including tornados. 
 

it only takes one cold air intrusion timed right to get a good winter storm. 
 

I would be surprised to see lots of below normal temps.

So much is loaded into the net result of everyday winter weather but it’s going to be intriguing to see play out. We’ve had a lot of cold and dry the past few years with a southern jet that just can’t get the job done and watching everything get suppressed. I think we swing the pendulum the other way this year but hopefully not too much. My fear is that it’s indeed BN for much of the season with AN precip but I think it’s driven by a lot of 45° rainstorms - not snow. But we only need to connect on one for it to be a good winter in this forum.

A lot of 45 degree rains would themselves be great news to relieve the drought. A lot of rains at any temp! Relieving the drought would make it a good winter whether or not any there are any widespread SE winter storms. If one happens to be a winter storm, which wouldn’t be hard to occur, that would be icing on the cake.

I would be thrilled to see us have a wet winter regardless of precipitation type.  But odds for sustained cold or multiple winter storms seem stacked against us.  It only takes one like in 1983. The problem is our cold source region tends be depleted of arctic air during a strong nino.

Not familiar with the author but interesting reading on a hot summer day regarding increased potential for positive PNA this winter and some of the data and science behind this potential pattern.

I just posted this elsewhere:

1. Asheville temp. records go back to 1876 and thus include 1877-8. Whereas Dec was mild/AN at 43.6, Jan was actually snowy and cold/BN (35.2) and Feb was NN (39.8). So, DJF averaged 39.5, which is actually NN. 

In Jan, they had well above normal snow with 4” on the 4th and 4.5” on the 31st! They had a low of 7F on the 7th. So, I wonder why this source per your post said:

The winter of 1877–1878 in North Carolina was remarkably warm, largely recognized as an exceptionally mild season brought on by a historic 'Super' El Niño event.

This doesn’t at all jibe with this Asheville data and I haven’t found any data for any other locale in NC going that far back.

Data from here:

https://www.weather.gov/wrh/Climate?wfo=gsp

—————

2. Regarding other super-El Nino winters in the SE:
-1888-8: Feb 1889 had a SE major snowstorm and was cold allowing for DJF to avg BN

-1957-8: cold winter overall with cold in Jan and especially Feb. and was snowy overall, esp in Feb, which included deep SE

-1965-6: cold winter overall thanks to quite cold in Jan and overall snowy in part of SE thanks to Jan/Feb

-1972-3: historic ZR Jan N GA and vicinity; historic snowstorm Feb AL to NC, including deep SE; overall NN temps with BN Feb

-1982-3: very snowy much of SE, including historic snow much of area in spring! ATL had biggest snowstorm as well as snowiest winter since 1939-40! It hasn’t been matched since! Overall NN temps.

-1991-2: ATL and nearby had a major snowstorm in Jan. Otherwise it was a mild winter.

-1997-8: NN temps overall with cold Dec, mild Jan, and NN Feb

-2015-6: AN temps overall due to warmest on record Dec as JF were actually BN to NN
—————

In summary, 
-a super-Nino doesn’t point to an expected warm SE winter as only 2 of the 9 averaged mild in DJF. Only one, 1991-2, averaged mild throughout DJF.
-Super El Niño winters tend to average mild in the N tier of the US, not the SE.
-Dec will be favored to be AN as 6 of these 9 had a mild Dec, including the warmest on record
-Jan/Feb averaged out will be favored to be BN with most of the 9 BN overall, with some quite cold months in some cases
-AN wintry precip prospects are better than avg. All it takes is one major snow in the SE in many cases.
-AN rainfall prospect is the best news of all due to the drought!

Good stuff!  Thanks for researching.  I was a senior in HS in 82/83. December was mild as I recall after a cool November.   We had a small event of about 3” in early January from a Miller A.  Another 3” event later in the month. Then we had the record breaker in March. So it was snowy winter in the upstate.   
 

The 1877/1878 is interesting. It is known as the Year Without Winter in the US.  But your temp records seem to indicate a lot of BN in SE.  This would align climatically with a Nino in the SE.  I’m excited to see what is in store this winter!
