I said in my post that EVERY month since April verified significantly too warm. That’s five months in a row, not just August. I pointed out Aug because your two maps showed how much Aug had to be revised down. But April, May, June, and July also had to be similarly revised significantly down. I’ve got all of the maps saved and can post them if necessary.

did someone call for big heat? that's nearly impossible after early September

I think assuming the relatively poor verification of a single month of August is bad logic. Every month prior to the past verified near or higher than models effectively. The warm water is still there and will eventually head west. BOM RONI forecast of 3.7 is effectively an ERSSTv6 RONI forecast of 3.0. Given the sst dataset and satellite integration. Its in line with other models just biased that warm direction.

If we don’t get a dirty airmass with debris clouds 85-90 possible next week. It’s really toasty at 850.

That's above normal yes, but not big heat.

The preliminary data reveal that Summer 2026 swept past Summers 1936 and 2021 to easily become the warmest summer on record for the contiguous United States. Five of the ten warmest summers have occurred since 2020. Just two occurred during the 1930s.

In Sept of 2023, the UKMET did much better than the way too warm BoM and was about the best of all models. Sept ‘23 UKMET progged ONI peak ~+2.0, which verified almost perfectly: I’ll be anxiously awaiting the Sept ‘26 UKMET ONI peak forecast. Here’s August of ‘26: ~+3.0. Keep in mind that this is ONI, not RONI! https://www.metoffice.gov.uk/research/climate/seasonal-to-decadal/gpc-outlooks/el-nino-la-nina

Looks like back to the future lol

Exactly... While arctic sand / powder storms might be hard to come by, ante is upped for slush bombs?

Ensembles are in agreement in above normal height fields and 2 meter temp anomalies for the first half of next week. This supports above normal temps for the first half of next week...mainly in the upper 70s to the middle 80s

Yep, the BoM monthly relative peak actually rose ~0.1 over the last month to ~+3.7, very much unlike the drop of 0.5 of the CFSv2 RONI trimonthly peak. Also, it unlike most others keeps it almost that high in Dec. I expect BoM will bust significantly too warm for this progged relative monthly peak of +3.7 like it did in 2023, when it was the warmest and verified way too warm. Also, note that every month since April on the BoM has busted significantly too warm. One can even see that for Aug by comparing your two graphs: the Aug 8th run had Aug way up at +2.7. The Sep 5th run lowered it down to +2.35. (I believe that the BoM uses a different dataset anomaly that makes it warmer than NOAA as you probably realize. I think it uses the warmer CRW as a base at least to an extent. That only adds to confusion.) The BoM (AUS-Access) had a whopping +2.9 for its peak forecast in its Sept ‘23 run! NDJ verified 0.9 too warm and DJF verified 1.1 too warm vs the NOAA ONI table seen at the link at the bottom of this post: https://www.cpc.ncep.noaa.gov/products/analysis_monitoring/enso/oni/v6/

Yea, the EURO was better...but I'm willing to bet that the CANSIPS and JAMSTEC have missed by more than the CFS.

Mid 80s today and tomorrow......that's it.

Couldn’t agree more. We will have our chances.

66 degrees at noon. hell of a way to run a TORCH!

Bom weekly data runs hotter than other agencies so you gotta compare apples to apples. The latest forecast compared to the one from just under a month ago:

Astra did a really good job.

Its also mostly just the cfs. The 3.4 ONI on the ecmwf plumes is very similar from August to September with a peak around 4C. The CCSC/IRI plumes average went up from the July 20 to the August 19 forecast. The early September BOM forecast had a similar peak to the early August one.

MORE damned heat and 75 dews next week?! Are you kidding me?! FFS.

6z euro for tomorrows rain: >0.75” 12z NAM nest for tomorrow: 0.00”

The MEI v2 was just released for JA: +2.5 vs +2.4 for JJ. That’s the 2nd bimonthly in a row at a record high for the bimonth (back to 1979). The record high for any bimonth is +2.9. Here’s the rundown for JAs of +0.5+: 2026: +2.5 1997: +2.3 2015: +2.0 1982: +1.9 1987: +1.5 2002: +1.0 1986: +1.0 1994: +0.9 2004: +0.8 2009: +0.6 2006: +0.6 1993: +0.6 2023: +0.5 2018: +0.5 1979: +0.5
