That’s interesting that it dropped slightly. But it’s still a record high back to 1979 for AS. For all bimonthlies, the record high is 2.9 (AM of 1983).

Very nice ice!

I wonder if the GA/AL game in Tuscaloosa on Sat night (7:30PM EDT start) will be heavily impacted by the Gulf tropical cyclone forecasted to form soon. Any guesses?

Do you think that the GA/AL game in Tuscaloosa on Sat night (7:30PM EDT start) will be heavily impacted? Edit: NHC track takes it past Tuscaloosa early afternoon. That tells me that the game itself during the evening shouldn’t be affected too heavily.

Today’s Euro weekly for 10/5-11 is the final one: Look how much the cold signal for 10/5-11 in the E weakened overall over the last 10 days. However, the signal remained at about the same level in from the NE to down the coast NYC to Hatteras: Sep 25th run for 10/5-11: much stronger cold signal Week 2 (10/12-18) is warm. Just a few days ago it was cool. Other than week 1, the only other cool E weak is week three, 10/19-25: this week has been mainly coolish over the last week of runs:

Today’s NOAA weekly relative ENSO release for last week: 23SEP2026 3.9 3.1 2.2 0.1 30SEP2026 4.5 3.3 2.3 0.1 Nino 1+2 warmed up strongly (0.6) to +4.5! For the week, it obliterates the prior record back to 1981 of +3.5 (1997). It is only barely shy of the all time record for any week of +4.6 (6/29/1983). Nino 3 warmed up by 0.2 to +3.3. That’s a new record high for the week with it beating the +2.8 of 1997. The record for any week is +3.6 (12/29/1982). Nino 3.4 warmed slightly to +2.3. This barely beats the +2.2 of 1982 for the week. The warmest for any week is +2.9 (12/29/82). Nino 4 remained at only +0.1, which in combo with the way warmer Nino 3 and Nino 1+2, makes ‘26 easily the most E based Nino on record. https://www.cpc.ncep.noaa.gov/data/indices/rel_wksst9120.txt

60%/80% now: Tropical Weather Outlook NWS National Hurricane Center Miami FL 200 PM EDT Mon Oct 5 2026 For the North Atlantic...Caribbean Sea and the Gulf of America: 1. Southwestern Gulf of America (AL92): A trough of low pressure over the southwestern Gulf of America is producing disorganized showers and thunderstorms. Although environmental conditions appear to be marginally conducive, gradual development is becoming more likely, and a tropical depression is expected to form during the middle portion of the week. This system is expected to drift eastward over the next couple of days, before it turns northward. It is too early to determine the specific impacts to the northern Gulf Coast, but interests there should closely monitor the progress of this system. * Formation chance through 48 hours...medium...60 percent. * Formation chance through 7 days...high...80 percent.

The thread for the Gulf tropical threat has been started:

We’re almost certainly heading for the most E based Nino on record for good or for bad. The SE ridge should be held back bigly, which would be really good from my perspective.

Thanks, Mitch. Here are the Euro Oct progs for winter going back to 2017-8 for comparison purposes and how they did in the E US: 2026: 2025: much too warm 2024: much too warm 2023 (Nino): too cold 2022: too cold (not warm enough) 2021: net slightly too warm (close SE, too warm NE) 2020: net too warm (much too warm SE; avg of too warm NE but close N Eng) 2019: pretty close (slightly too cold SE but close NE) 2018 (Nino): net too cold (close NE but much too cold SE): 2017: close ———————— Tally: -did well in 19 and esp. 17 -did pretty well 21 -did pretty badly 23, 22, 20, 18 -did terribly 25, 24 -too cold both El Niños in SE and 1 of 2 in NE -NE: too warm on 4, close on 3, too cold on 2 -SE: too warm on 3, close on 2, too cold on 4

Indeed! Model consensus has plentiful to possibly even flooding rains (especially on/near the Gulf coast) in some areas of the SE this weekend!
