My guess for the rest of this season is that the ACE will finish below the 161 level of last year. I guess this means the upcoming winter is cooked and torched. I had a below 161 ACE before the season even begun, and it was pretty apparent by mid-June. The better question now is if we're even going to hit half of 161 ACE.

Stormchaserchuck1 Posted 7 hours ago Share Posted 7 hours ago GFS ensemble mean has -400dm over Wisconsin in 2 days. I wonder when was the last time we had the 5400dm line in the US within 45 days of the hottest of the year? It comes in as purple, and that's been a rare pattern lately, only really happening over the AO and NAO regions. Link to comment Share on other sites More sharing options...

The better question now is if we're even going to hit half of 161 ACE. - I predicted 139 ACE in the contest before the season started. -There's still a long way to go based on it being La Niña and also considering that recent La Niña seasons have been more backended than in the past. -IF ACE ends up low, I’ll give you kudos. If not I hope you’ll be humble and admit you were wrong. Link to comment Share on other sites More sharing options...

The heart of the winter looks coldest relative to average, but there are questions as to how it starts and ends. He seems to do this every year. He understands that the holiday season is a high profile season due to travel and other activities. He understands the romantic power of a "white Christmas." Thus, he seizes upon the element of timing to pull emotional triggers and set a digital wildfire with his calls for a cold and often snowy Thanksgiving to Christmas. Almost certainly, the mention of snow will be made as the holidays draw closer to ensure maximum attention and to keep the digital fire burning. He also understands that memories are short-term. All the failed forecasts will be forgotten. They always are. Thus, he recycles his calls over and over again in what ultimately is a successful pursuit of clicks. In this social media game, "winning" is defined by clicks not accuracy. Having said this, La Niña winters can get off to a fast start. But with some exceptions, they fade as the forcing shifts. 2 1 Link to comment Share on other sites More sharing options...

PhiEaglesfan712 Posted 6 hours ago Share Posted 6 hours ago 12 hours ago, Stormchaserchuck1 said: It's been pretty constant central-subsurface cold since the 23-24 El Nino. You can see how the surface has been running much warmer than the subsurface (more credence to RONI), which makes me think that when we finally do shift to El Nino, it will be warmer than the subsurface Kelvin Waves would indicate. Pretty good chance we go to El Nino in 2026 or 2027. It looks like the ONI and RONI are converging: JJA 2025 ONI (NOAA): -0.2 JJA 2025 RONI: -0.46 August 2025 PDO: -3.23 (July 2025 PDO was adjusted to -4.12) If the el nino happens in 2026-27, I can only see it going weak or moderate. If it happens in 2027-28, it will be much stronger with the extra year to develop. (I mean, it's no surprise the 15-16 el nino was very strong because of the extra 3 years it had to develop. It didn't happen in 12-13 as most people thought, or even 14-15.) Link to comment Share on other sites More sharing options...

GaWx Posted 6 hours ago Share Posted 6 hours ago RONI-ONI differences have been slowly dropping since late in 2024 and especially since FMA: 2024: JJA -0.54 JAS -0.52 ASO -0.54 SON -0.55 OND -0.55 NDJ -0.54 DJF -0.53 2025: JFM -0.51 FMA -0.49 MAM -0.43 AMJ -0.38 MJJ -0.32 JJA -0.29 1 Link to comment Share on other sites More sharing options...

If Nino 1+2 does not return to an el nino state, then this winter will have a more la nina feel to it. Last year felt like a tug-of-war between the la nina in 3.4 and the el nino in 1+2. It certainly did not behave like a la nina. Link to comment Share on other sites More sharing options...

Severe cold cold snow from Thanksgiving until till New Year’s, “December to remember” Actually, a snowy Thanksgiving to New Years would be a classic weak Nina in the Great Lakes (not sure about the east coast). The issue in recent years has been Ninas have had a tendency to flip flop Dec & Feb. Link to comment Share on other sites More sharing options...
donsutherland1 Posted 4 hours ago Share Posted 4 hours ago Here's how La Niñas transition (using New York City's data) following cooler than normal and warmer than normal Septembers: In general, warmer Septembers are often followed by milder and less snowy winters. Cooler Septembers slightly favor colder winters (especially January, possibly due to more persistent forcing) with greater snowfall potential.

George001 Posted 3 hours ago Share Posted 3 hours ago 3 hours ago, anthonymm said: It seems like people are pretty much already set on a niña? Are we jumping the gun? We have seen significant cooling in the ENSO 3.4 region in the past month, it is already down to -0.8 on the daily, and -0.4 on the weeklies. When taking into account the current guidance and historical precedence (the last 3 strong El Niños were immediately followed by multi year La Niñas), it is the logical conclusion to make. So I would disagree that people are jumping the gun about the ENSO state for this winter. The big question is will the La Niña be east based, basin wide, or a modoki event. Right now guidance is favoring an east based event. Link to comment Share on other sites More sharing options...

Last year felt like a tug-of-war between the la nina in 3.4 and the el nino in 1+2. It certainly did not behave like a la nina. Cold ENSO 3.4 and warm ENSO 1+2 is still a La Niña, just a different kind of La Niña (modoki La Niña). At times it didn’t behave like a La Niña, but that is more because it was so weak than what ENSO 1+2 was doing. In Feb though the storm track was consistent with a modoki event. In modoki events storms tend to take more of a northern track, which is why they are unfavorable for big snows outside of NNE. There was a lot of low level cold though, so it got icy.
