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

    Will, thanks for posting. Unfortunately, WB CFS temp. maps have major algo flaws and thus I rarely post them. Example: they usually have a major cold spot over S Lake Michigan and a major warm spot over N L. Mich & vicinity just 250 miles to the N! Also, they tend to have too much contrast between well inland areas of the E 1/2 of the US (too cold) and the much warmer near E coast (often too warm). Related to this, WB shows at/near record cold Feb/Mar of -5 to -7C (and even vs the colder 1981-2010 climo!) in those areas with the 3rd-6th shades of green based on the means of 30 days of runs. The CFSv2 site shows nothing of the sort: examples for Feb: 1) Columbus, GA, in Feb is ~-3.5C vs 1991-2020 for the avg of the 3 maps below from the CFSv2 site, itself, whereas WB has them ~-5C vs the colder 1981-2010 or ~2C/3.6F too cold (1991-2020 is 0.5C warmer than 1981-2010). 2) At the same time, the NC/VA border on E coast in Feb is ~-1.5C vs 1991-2020 on CFSv2 compared to NN on WB vs the colder 1981-2010 meaning WB is ~1C too warm 8/6-15: 8/16-25: 8/26-9/4:

    1. My post started with “Consistent with OISST, the August relative ERSST anomaly for Nino 3.4 just came out”. Thus it should be understood by anyone following along that the entire post is talking about “relative” anomalies. 2. My entire post is addressing anomalies, not absolutes. You’re using an absolute in your example. 3. Relative anomalies are now official for NOAA and BoM at the least. 4. The outdated traditional way of determining anomalies is currently inflated ~0.5C due to GW. 4. August of 2026 was very warm, but it wasn’t the warmest relative 3.4 anomaly on record as Aug of 1997 was 0.18 warmer. 5. The main point of my post is that the models had way too rapid warming in 3.4 from July to August. The relative anomaly in 3.4 warmed only 0.34C per ERSST, which prevented a record high relative 3.4 anomaly for Aug. like had been progged.

    Nino 1+2 (keep in mind that this is non-relative) had a strong rise yesterday. Get ready for a tweet from Adam, Abraham, and/or others addressing this saying record breaking yada yada yada. Keep in mind though that records from 1982-3 and 1997-8 are based on weeklies, not dailies. Also, highest relative WEEKLY in 1983 was +4.6 and in 1997 was +4.1. Let’s see where the current calendar week relative 1+2 on Monday. It won’t be anywhere near +4.6 although it may get close to +4.0.

    Consistent with OISST, the August relative ERSST anomaly for Nino 3.4 just came out and it also shows a rather mundane warming in August vs July compared to the near record breaking rapid warming of ~1C that several models had been showing. The Nino 3.4 anomaly warmed by only 0.34: 2026 6 1.07 2026 7 1.33 2026 8 1.67 It had been earlier progged to be >+2 for August. For example, check out this June 13-22 mean CFSv2 prog for August: +2.3, which was notably above what verified: How does August of ‘26 compare to other very warm Nino Augusts since 1950? It’s very warm but still wasn’t the warmest as 1997 was 0.18 warmer. Had it warmed to +2+ like had been progged, August would have easily been the warmest on record: 2026 +1.67 2015 +1.58 1997 +1.85 1987 +1.27 1982 +0.93 1972 +1.47 1965 +1.57 1957 +1.36 https://www.cpc.ncep.noaa.gov/data/indices/Rnino34.ascii.txt

    CFSv2 progs for relative Nino 3.4 trimonthly peak continue to cool significantly as the overall flatness of Nino 3.4 still persists (much longer than earlier progged on the models for 3.4): Mean of runs Aug 4-13: OND +3.5 (when the progged peak was at a peak) Mean of runs Aug 14-23: OND back down to +3.25 Mean of runs Aug 24-Sep 2: OND down even further to +3.1! It hasn’t been this low since the 10 day means of late June:

    There was lightning delay/heavy thunderstorm at GT for their game vs Prime Time’s CO Buffaloes. But the storm is already moving out rapidly to the W. Go Jackets!

    Thanks to forky, Adam @snowman19 is back!

    Oops, I forgot to break down by months. I think Dec/Feb will have the best chance to have the warmest/coldest anomalies among DJF, which is consistent with strong Nino analogs and model consensus for the E US. In the SE when we’ve had 1-2 big winter storms, they’ve tended to be mainly between the 2nd half of Jan and March. A major exception was the SE major winter storm of early Dec of 1896! So, of course, one never knows. @Newman

    I agree he’s a major blowhard and not a nice person, and he’s been dead wrong on several things (including claiming “Heat Dome” is a recent term used primarily by alarmists and first claiming this disaster was caused by an earthquake). However, I don’t think it’s a waste of time to post his stuff as especially Don and I have done the last few months. Because he’s been widely read/quoted in recent months, he often shows data to support his posts (whether misleading or not), and is smart/well spoken/pretty clear communicator, I think his posts should be addressed here whether in disagreement or not. A person like him who many here including myself have strongly disagreed with at least some of the time is the perfect person to bring into the forum to make for robust discussion and the debating of differing viewpoints. To avoid people with very different views tends to make forums like this and others closer to an echo chamber. The most interesting forums aren’t afraid to consider major differences of opinion and debate them. Also, it’s good to be open-minded as I feel I am on most topics. On this topic, I’m very open-minded.

    Hello Newman, For this winter, I’m thinking (none of this should be surprising based on super Nino analogs/models): -above normal precip (up to 3” above) within a couple hundred miles of the NE coast with highest anomalies near the coast and closer to normal well inland -above to MA normal precip SE with the largest anomalies in the deep SE/FL, where 4-8” will be common -anomalies tending to get colder as one goes further SE -New England/NE US likely to average 3-5F warmer than normal with warmest in N New England -Mid-Atlantic will likely average ~1-3F warmer than normal with closest to normal near coast -SE likely averaging near normal to slightly colder than normal with coldest anomalies deep SE/FL -Regarding wintry precip overall, the SE tends to do best anomalywise in moderate or stronger El Niño winters. But even so, much of the SE, especially deep, is unforecastable since it takes only 1-2 winter storms (often just 1) to make it a very wintry winter there. But that chance tends to be best with El Niño winters vs other winters averaged out. Strong+ Nino winters have tended to have the best chance though moderate may be close.

    Indeed, it has become more E based despite a flat Nino 3.4 recently since Nino 3 has warmed some while Nino 4 has cooled some netting out to an essentially flat period for Nino 3.4.

    Thanks, Charlie. Interesting. The contradiction of viewpoints/supporting data and info as well as the complexities involved in this terrible disaster are why I said that most of what Martz put in that post is at least worthy of discussion/debate. I think that the odds of CC being at least a little involved are high. I feel that the main debate is whether CC was a major factor or just a minor factor. I agree that it’s too early to conclude anything and there likely will be continued disagreements in upcoming releases. We may never know the exact answer.

    Nino 1+2 is very warm, but Adam’s post: -is ignoring the effect of GW on skewing Nino 1+2 upward in 2026 vs 1997. The highest relative weekly in 1997 was +4.1 (set twice). Relative values for Nino 1+2 are currently 0.5 or more cooler than the non-relatives. NOAA and other orgs have recently been using relative values as official because of the skewing caused by GW. -He’s looking at yesterday’s daily rather than at a weekly average, which is what the historical data is based on. -These OISST charts have recently been warmer than the released NOAA weeklies as has been noted in many posts since July. -Let’s see what this Monday shows for relative Nino 1+2 averaged over this week. I doubt it will reach +4.1, but we’ll see. I’m guessing high 3s.

    I’m not aware of a relative PDO. Like the SOI and IOD, I don’t think relative is needed for these 3 indices because all 3 are based on differences between different areas that I assume largely cancel out any effect from GW. I do see why there are now two NOAA PDOs: yours is based on ERSST version 5 whereas mine is based on ERSST version 6, the newest version. How about that for adding to confusion? With 6 being the newest ERSST, I assume that it is the most official for NOAA PDO now.

    That says August. The August forecast isn’t new. The Sept 1st forecast is the new one we’re waiting for. The monthly Euro forecasts are normally released on the 5th of the month.

    The NOAA August PDO came in at -1.11 vs July’s -1.35. This is the 2nd month in a row for which the NOAA monthly actually came in less negative than what the WCS dailies suggested (see image below). That is even more the case with August, for which the WCS averaged slightly lower than -1.5. This -1.11 compares to the significantly stronger -PDO of Aug of 2023 of -2.02: https://www.ncei.noaa.gov/pub/data/cmb/ersst/v5/v6/index/ersst.v6.pdo.dat

    Thanks for your reply, John. I’m asking anyone but tagged Don only because he’s been about the most involved with me in the discussion about the Nepal disaster and thus wanted to make sure he sees this. Martz appears to be correct in saying that there aren’t going to be many days that go >0C based on my just now seeing what’s down below that I’m quoting from the link below. If ~+1C really is the warmest at 5,364 m or 17.6K feet, is there going to be significant melting way up that high? https://www.quora.com/What-are-the-highest-and-lowest-temperatures-ever-recorded-at-Mt-Everest-base-camp “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.”

    Yes, the cocky Chris Martz was wrong with his initial thought that this disaster was earthquake induced. But I think most of this from him yesterday is at least worthy of discussion/debate. Opinions? Climate alarmists refuse to let go of their narrative about Nepal despite the load of evidence against their claims. The avalanche (and by extension, flood) in Nepal last week was triggered by the collapse of bedrock beneath the Yala Glacier, not the glacier partially collapsing itself. Global warming doesn’t cause bedrock to buckle. It was likely geological in origin caused by seismic activity in recent years and months causing fractures in the rock. The Himalaya are highly active due to plate tectonics moving India into the Asian continent. And the “melting permafrost” argument doesn’t hold much water either because temperatures have generally been below freezing, even during summer, where the glacier sits ~17,000 feet (5,200 meters) up. You aren’t going to see a lot of days get above 0°C (32°F). Not every environmental disaster that happens needs to be blamed on humans. Nature itself is more than capable of causing these types of events. It’s time to get rid of the mentality that mankind is the cause of every bad thing that happens. @donsutherland1
