 The hot summer of 1991 was an exception.

July 1991 actually had a cooler El Niño-like -0.52 pattern across the CONUS compared to the record warmth this July at +2.4.

July 1991

73.87°F

-0.52°F

It's going to be a close call, but it now appears more likely than not that July 2026 will be the warmest month on record in the Contiguous U.S. As of today, we are essentially tied with July 1936 and July 2012.

I truly would laugh so hard if we end up getting a solid winter out of this event just so I can stop seeing the repetitive posts on here.

I wouldn't because I think it will be solid.

The 2015-2016 winter was absurdly unremarkable except for that monster blizzard. I almost got my entire seasons worth of snow just from that one storm alone. Otherwise it barely snowed at all.

The arctic outbreak INVO VD Day was pretty remarkable.

 Chris, my point is that the summer of 1991 didn’t follow the pattern of the mean of the other 5 as it was net warmer than normal in the E 1/2 of the Conus vs it being colder than normal for the other 5 years averaged out:

I buy that for the mid atlantic but even up here? I’m concerned it will be too warm for sustained winter and we aren’t going to get the nickle and dime events we normally get.

CANSIPS now getting close to a +4C ONI peak…

 1. The July SOI comes in way down at -26.8,  by far the lowest July SOI on record. The only lower ones during met. summer were the -27.7 in June of 1905 and the -27.0 in June of 1896, both incoming El Niños.

2. This brings us to 82 straight days of -SOI. Going back to when records are readily available (since 1991), this is second only to the 100 days of 1998! It’s too early to tell whether or not the current streak will reach 100 days.

97-98 was not half bad for the Great Lakes/SNE if i remember correctly. December ‘97 was decent here while it was a total shutout in 2015.

People forget that our coldest winter CONUS in the 21st century happened during a strong el nino.

The 23/24 Nino was supposed to be very favorable for snows but it ended up being one the warmest/least snowiest. 

ENSO is still just one factor

My sister was born July 18, 1991. I was 8 years old and I remember how brutally hot and humid it was. My mom always talks about how it was so hot when she was born.

 Darwin’s pressure has averaged 1015+ mb, a high pressure for there, for 22 straight days! That’s a new record (back to 1991) that breaks the old record of 20 days that was set during another developing super Nino, July of 2015. I’m expecting that streak to finally end tomorrow.

97-98 wasnt the disaster here that it was on the east coast, but it was one of the last strong Ninos Id pick, only '82-83 was worse. Interesting about '97-98 is that it was front-loaded and Feb was a shutout. mid Nov to mid Dec was actually decent. So was the 2nd half of Jan. Everything else sucked.

Shittiest strong Ninos locally: 1982-83, 1997-98, 2023-24

Best strong Ninos locally: 1877-78, 1972-73, 2015-16

At Detroit, the least snowy strong Nino is 1982-83 with 20.0" and the snowiest 45.0" in 1972-73.

Out of the dozens of (pre) El Niño summers, 1991 was the 2nd hottest at Detroit on record with only the pre late developing weak Nino summer of 2018 hotter! The 3rd hottest Nino summer was 2002, which preceded a very snowy and cold winter that was one of the coldest and snowiest moderate or stronger El Niño winters there as you know.

It was. My daughter was born in August of 91'. My wife remembers it in more detail than me! Lol

People think Super Nino means warm too automatically. The NAO/AO play a role, and if you map N. Pacific 500mb anomalies historically with Super Nino's you will see a N. Pacific trough placement in the cold season where it is usually doesn't extend a 2nd wave ridge so far east. 

Some assume theres some linear connection with the strength of nino and how warm it will be and simply ignore everything else.

Yeah, the real connection is with global temperatures. A huge trough over the North Pacific is necessarily Winter disaster for the east coast.

 Hot off the press from another source posting the 8/1/26 Cansips run of Nino SST anomalies. It is continuing the CanSIPS run trend of moving the strongest warm SST anomalies further and further east at the ~Nov peak. That’s not surprising because I’ve been suspecting a Modoki bias for it based on the past few years of analyzing it as I’ve posted a number of times here before.

 The April-June 1st runs had the warmest anomalies near the Dateline/straight Modoki (W based) in the peak month of Nov. Then the July 1st had warmest anomalies in Nov further E near 160W, more of a cross between central based and Modoki.
 

 The new Cansips run’s Nov peak shows the warmest anomalies centered near 130W, which would be centered in E Nino 3.4/Nino 3 making it pretty E based. Though this run is not as E based as 1997-8, stay tuned to future runs because the E trend of the strongest anomalies on Cansips from run to run may very well not be done due to this suspected Modoki bias.

 I can’t post it because the file size is much too large for me to have room in my account. But when it comes out on TT and WxBell, those will be smaller files and thus postable.

The summer of 1991 only had a weak El Niño in progress as opposed the strongest on record this summer. July did have some similarity to the composite.

But sometimes weaker El Niño summers in the past had more heat than the stronger developing ones. This was the case in 2002 also.

So it has been common in the past for weaker El Niños to have less influence in the midlatitudes than during developing super El Niños like 2023, 2015, 1997, 1982, and 1972 which had the more typical cooler summers. 

The big story this summer is how out of phase the mid-latitudes and tropics are for the magnitude of this event.
