2026-2027 Super El Nino
40/70 Benchmark replied to Stormchaserchuck1's topic in Weather Forecasting and Discussion
@Stormchaserchuck1What did you say the SD of your formula is? .30? 70% of getting .30 within the outcome? @bluewaveDo you know where that post is that you made comparing past seasonal forecasts to reality? TIA. -
Sioux City ASOS site hit 83 degree dewpoint earlier this evening, and hit 119 for heat index. Tremendous pool of 80+ degree dews from southwest MN down into northeastern KS.

Possibly. However we know what would happen in the playoffs with him so it wouldn't really matter, lol

2026-2027 Super El Nino
raindancewx replied to Stormchaserchuck1's topic in Weather Forecasting and Discussion
I found some of my old research and updated it for the last few years (2021-2025). It looks like the formulas still work for predicting precipitation locally in El Nino / La Nina seasonally, and even month by month. El Nino DJF precip locally can be predicted at very high confidence (90%, within 0.8" of output, 75% odds of within 0.59") using the Sept high, Nov precipitation, and wet days in July-Sept (+1/2 of wet Jun days). Formula is: =(B13*-0.04239*B13)-(0.30999*B13*C13)-(0.018527*B13*D13)+(0.01853*C13*C13)-(0.2244*C13*D13)+(0.00347*D13*D13)+(7.277*B13)+(28.465*C13)+(1.6066*D13)-(311.76) Where B is Sept high, C is Nov precip, D is Wet days. DJF highs in El Ninos locally tend to match DJF ONI, July-Jun annual sunspots, and DJF ONIp, within ~2.3F or so 90% of years. Here is 2023-24 as an example: I never was able to find an El Nino at that solar level / trajectory - 129.6 in the rising part of the cycle. The peak was 149.2 for 2024-25 (Jul-Jun). This is the only El Nino since 1931 one year from rising to the peak. 1957, 1968, 1979 are at the peak, not before. Dec El ONI Sun ONIp DJF Tmax 1939 1.0 125.9 -1.0 49.8 1957 1.8 281.6 -0.2 50.5 1972 1.8 75.4 -0.7 45.2 1982 2.2 129.2 -0.1 47.9 1994 1.0 36.9 0.1 54.4 Blend 1.6 129.8 -0.4 49.6 2023 1.9 129.6 -0.5 51.4 For 2026-27, there is probably no real way to use my method given what is forecast (ONI at +3.0C to +3.5C in DJF). But you can use solar (60-80?) and ONIp as anchors. Dec El ONI Sun ONIp DJF Tmax 1965 1.4 37.1 -0.6 44.4 1972 1.8 75.4 -0.7 45.2 1982 2.2 129.2 -0.1 47.9 1997 2.2 54.9 -0.5 47.1 2015 2.5 55.8 0.6 51.4 2023 1.9 129.6 -0.5 51.4 Blend 2.0 80.3 -0.3 47.9 2026 3.1 75 -0.4 47 Solar was 106.2 sunspots/month from July 2025-June 2026, and declining. Similar initial positions/trends (roughly: 86-126) were 1939-40 (126), 1950-51 (103), 1960-61 (117), 1971-72 (101), 1982-83 (129), 1992-93 (103), 2002-03 (131), 2014-15 (91). The following years imply ~72 sunspots/month for July 2026-Jun 2027. If you use just the solar cycle positioning/tendency, you can see 1950-51 and 2002-03 as a blend is very similar to last year for temps - -

Central PA Summer 2026 Discussion/Obs Thread
Yardstickgozinya replied to Voyager's topic in Upstate New York/Pennsylvania
@TheDreamTraveler I was reading back over posts from the other day and noticed that I made a typo. Shortly after you posted about setting a record low, I posted a comment that said "New records are broken here and not very impressive ". I use a voice app that doesn't always copy my voice properly and sometimes I miss my mistakes.. What I wanted to say was "No new records we're broken here and not very impressive". I was actually referring to the comet thatI made about stretching and making fun of myself.., however I now realize it may not have came across as such. -
.32 for the day here, most if came in the morning hours. Then a cloudy cool day. Felt nice walking into the garage and now walk into a furnace blast for a change. Was a good few weeks period here for rainfall. High for the day got to 72.8 at 17:59.

Point had us up to 94 today, low stratus hung around a lot longer than expected and we briefly topped out at 86.

2026-2027 Super El Nino

Absolutely agreed with this....the warmth in 1.2 renders it a moot point in terms of the seasonal mean, however the warmth in the rest leave the door open for some volatility IMHO. Regardless, it will be warm overall. -
60s at 9pm on July 25th. I'll take it
