    The CFS 10 day for Nov has warmed 2-3F since 20 days ago: Latest: 20 days ago:

    Indeed, the -SOI went + on Oct 24th (today) making it 72 days: https://data.longpaddock.qld.gov.au/SeasonalClimateOutlook/SouthernOscillationIndex/SOIDataFiles/DailySOI1887-1989Base.txt

    My answer: That’s why I prefer to compare 30 year normals rather than compare absolutes since temps are obviously warming due to GW, which is why I did that in my reply to Chris. Now in terms of 30 year climo based anomalies for Oct, ‘26 is coming in a bit warmer than the avg super Nino anom. at ATL for sure. So, I agree with Chris’ general idea about that.

    Ray, I personally don’t think it is all that big of a deal that ATL is projected to be ~1.8 F above normal for the FULL Oct of ‘26. I didn’t mean to imply that. After all, Oct of 1991 was almost as far AN with it at 1.6F AN. Of course he was just referring to Oct 1-22, which came in ~2.2 AN vs the normal of 66.4F. But even that isn’t a strong warm anomaly.

    Thanks, Chris. Good find! I went further and looked at all ATL Octs for +1.3+ Ninos back to the late 1800s (24 of them) and found only three that were 1.8+ warmer than normal, which is ~where the full Oct 2026 is projected. But they were all only higher end moderate: 1918 (+1.4 Nino): 65.8 (3.1 AN) 1941 (+1.3 Nino): 69.4 (5.9 AN) 2002 (+1.3 Nino): 65.4 (1.8 AN) The full Oct 2026 is projected to come out to ~66.1F or ~1.8 AN, which would tie with 1899 for the warmest vs normal for any Nino stronger than +1.4 peak. (I count 17 of them back to late 1800s). The warmest ATL Oct anomalies for El Niños stronger than +1.4 peak are: 1899 (1.8 AN) 1991 (1.6 AN) 2023 (1.4 AN) 1986 (1.2 AN) 1994 (1.1 AN)

    Latest Arctic ice falling back closer to the mean as the Arctic N of 80N anoms have warmed considerably:

    Feb in the E US will likely be heavily affected by the Feb NAO. The CFSv2 is implying a strong -NAO in Feb ‘27. -These Ninos had a strong +NAO in Feb: 1992, 2016, 2024 Here’s the Feb temp anom composite: -These Ninos had a strong -NAO in Feb: 1958, 1966, 2010 Here’s the Feb temp anom composite:

    -2016: much less E based Nino In the E US, the mid-Oct ‘15 forecast mean CFSv2 for Feb ‘16 actually verified slightly too warm overall in the E US! Verification of Feb ‘16 (vs 1981-2010): -2024, much weaker and less E based Nino: The mid-Oct ‘23 mean CFSv2 forecast for Feb ‘24 verified too cold NE but wasn’t too far off in the SE and was very close deep SE: Verification of Feb ‘24 (vs 1991-2020): How will it do for Feb ‘27? We’ll see! Yes, although I’m not at all trusting any model, I’m excited about the Feb potential (not Dec at all and not much for Jan though that could very well be transitioning):

    That’s still a moderate +PNA since SE US H5 anomalies are much lower than those for W Can. Then combine that with an off the charts E Can/W -NAO block diverting cold down into the SE. H5 anomalies are lowest in the SE US of anywhere on the globe in CFSv2 Feb fcast with -8 to -10 dam. Also, cold in SE, especially deep SE, has at most a modest correlation with -EPO: Edit: Also note that climo used by TT here is 1984-2009, which is colder than 1991-2020. So, had 1991-2020 been used instead, H5 anomalies over the E US would be even lower since mean H5 has warmed.

    Latest CFSv2 10 day mean 850 mb fcast anomalies for Feb of 2027: note that >75% of Conus BN, including ~1/3 of Conus 2-4 C BN, along with the extreme warmth in E Canada that is consistent with strong blocking there allowing the diverting of dominant Arctic cold into much of Conus: —————— In stark contrast, mid-Oct forecast for Feb ‘24: 85% AN in Conus/no block in E Canada in that much weaker/much less E based Nino vs 26-7: ————— In sharp contrast to mid-Oct forecast for Feb ‘16: only <15% BN, none sub -2C, and less extreme Canadian warmth centered >1,000 miles W of the Feb ‘27 forecast in that much less E based Nino vs 26-7:

    Today’s CFSv2 GLAAM forecast (see top image below): currently extremely high at +3 SD; though very high, Oct is not as high as record-breaking Sep (keep in mind that it amazingly exceeded +4 SD for a 6 day period (within 9/17-23), which may not happen again for decades): By latitude: similar pattern that has dominated for awhile with the strongest positive anomalies S of 20N: In contrast, 2023-4 was nothing of the sort:

    I just read that part of AZ on Wednesday had a tornado watch for the first time in 15 years!

    It appears per models that due to a combo of a large Tahiti SLP rise/smaller Darwin fall and despite it being way down at -43 today, it should break the very long current -SOI streak and go positive by ~Oct 25th. That means that the current -SOI streak would end near 74 days.

    1. For you: How’s the surf in your area? 2. For all: Can a subtropical cyclone attain hurricane force winds but still not be classified as tropical? We know there are ST depressions and storms, but I’ve never heard of a subtropical H. Why not?
