Winter 2026-2027 Seasonal Outlook

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.
