1. This very strong El Niño has a good chance to start helping out you and other SE dry areas by Nov and hopefully would then continue on/off through March as climo suggests. 2. I ended up getting very little from the late afternoon thunderstorms. It was only ~0.02”.

I’ve been getting light rain from thunderstorms during the last ~1/2 hour as it started ~4PM. I just heard pretty loud thunder from one fairly close CTG lightning strike.

I’m not disagreeing with you because I’m, myself, quite suspicious about the 1/15/22 Hunga-Tonga causing that delayed temp spike earlier in ‘23 than what the ‘23 El Niño should have caused. But if you were to post that in the CC forum, you’d get a lot of opposition or at least doubt based on past Hunga-Tonga discussions in there. Several folks there have downplayed it because they think the warming effect was minimal/far lower than that early ‘23 temp spike and they backed it up with at least one source fwiw.

Thanks. But this graph has avg for entire summer well over 0C? This is far warmer than what Chris Martz was suggesting about the site of the collapse (i.e., only occasionally reaching to barely above freezing), isn’t it?

Thanks, Don. Does that big a difference in temps for just 160 km away and 164 meters/538 feet elevation jibe with what you’d expect? Dry adiabatic rate is 3C/5.4F per 1000 feet, correct? So, on 2nd thought, maybe?

Although this 12Z 9/5/26 CFSv2 ens. AAM fcast is THE highest I’ve seen for the entire 35 day period, I realize that it has a + bias, especially the further out in the forecast period. I still haven’t seen anything forecasted at 4+ to verify even closely and even many of the 3+ forecast days have been overdone. This has 4+ for all 4 members by day 11 (Sept 15th), which along with the 0Z 9/5/26 forecast is at the earliest I’ve ever seen that high. It has 3+ starting on Sep. 8th. But as I alluded to, many runs had 3+ for all of mid to late Aug and all of Sept and few, if any, days actually hit 3+ since mid Aug. It even dipped briefly to just below +2 in late Aug! In this case, I expect it will reach 3+ within a few days based on how steep it has it rising now. But regarding it hitting 4+ Sep. 15th or even after, I’ll believe it when I see it!

I’m admittedly confused. Are we looking at the temp. data for the same place? Per my post from 3 days ago: “Highest and lowest recorded temperatures at Everest Base Camp (EBC) depend on which camp and which dataset, but reliable observations come from automatic weather stations (AWS) installed at the South Base Camp (Nepal side, ~5,364 m) and other nearby high-altitude stations. Summary of best-available values (observations and published AWS records, through May 2024): Highest recorded air temperature South (Nepal) Base Camp AWS: about −1.0 °C to +1.0 °C on the warmest days in late spring/early summer (typically May). Many published station summaries and expedition logs report peak values near 0 °C; a commonly cited peak is ~+0.5 °C. Slightly warmer spot measurements in sunlight or lower-elevation tent sites can exceed +1 °C briefly, but sustained, instrumented air-temperature peaks at the official South Base Camp are around 0 °C to +1 °C. @donsutherland1@Typhoon Tip

Lol!

Clemson at LSU originally had a 6:30PM CDT scheduled kickoff. But due to a lightning delay/heavy thunderstorms, they’re not kicking off til 8:40PM CDT! This supposedly would be the latest start in LSU history! I read that Lane Kiffin does not have either of the former pros on its roster for tonight. He’s worried due to a lawsuit by the SEC against LSU. The concern is that LSU would possibly have to forfeit any games with them on the roster. There’s also the worry about eventually being thrown out of the SEC although that’s very highly unlikely.

The worst E US Sept heatwave on record was during El Niño (1925).

Here are the relevant SLP maps for JFM NAO: JFM ’24: strong -NAO JFM ‘27: even stronger -NAO, which jibes with your comparison of JFM ‘24 to JFM ‘27. However, note that there are stronger SLP contrasts worldwide in ‘27 vs ‘24 and not just in the NAO region. Note that in ‘24, only ~1% has +2+ mb vs ~~10% in ‘27. Similarly, the % with -2- mb is sig. higher in ‘27 vs ‘24. Not sure what to make of that.

I’ll add that the globe is warmer over last 3 years helping to add to the huge increase in >+40m anomalies.

H5 comparisons Euro Sep fcasts for JFM ‘27 vs ‘24: larger contrasts worldwide/E US! ‘24: very little >40m (<5% of the globe) and no <-40m ‘27: much more >40m (~1/2 the globe) and sig. more <-40m (3 areas vs none in ‘24)

H5 comparisons Euro Sep fcasts for JFM ‘27 vs ‘24: larger contrasts worldwide/E US! ‘24: very little >40m (<5% of the globe) and no <-40m ‘27: much more >40m (~1/2 the globe) and sig. more <-40m (3 areas vs none in ‘24)

Comparison of Sept ‘23 Euro for DJF 23-4 and Sept ‘26 for DJF 26-7: ~twice the contrast N to S ‘26-7 vs ‘23-4 in E US ’23: ‘26:
