CFSv2 progs for 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): 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:

I imagine seasonal models will start trending warmer. Right now we are before that infamous Halloween predictability barrier. Now models (as programmed) are amping up Nino response because Nino is on fire. What's next? Warmer forecasts! ATMO has not followed teleconnections for years. First, the oceans are not absorbing heat. Marine heat waves are almost global. See Climate forum for more. Also the PDO remains out of whack. If we have warm Nino AND -PDO it'll flood the Lower 48 with mild air. My forecast remains a top 10 warm winter. Warmest winter in recorded history is possible.

Folks whining about the weather? Lolz

dewpoints starting to drop but will be tomorrow before it's really drier.

Incredible instability will be available. Unfortunately 15% is probably a good forecast. I was hoping for 30% wind, mainly for QPF. No turning with height, so those blobs are just beefy wind producers. No organized line. Derecho checklist is so far from being met that I'd say we meet the anti-derecho checklist. Simply nothing interesting in weather right now. When's the next comet or eclipse? We need some Northern Lights!

Yeah, it has been a furnace. I don't remember September being hot during Nino climatology. I do remember Octobers being cold. We need some cool air. These fall athletes are living in heat purgatory right now. They need a break! Reminds me of La Nina falls. Maybe the atmosphere is just repeating the pattern regardless of ENSO? Warm fall - endless summer. Flip to winter temps, 2-4 week lull, more winter, and short spring? At some point, fall "should" be cloudy and cool if Nino has anything to say about it - minus the flip.

Can we bring back the coastals this fall? NE 35 with gusts to 55 maybe.

Just got hit with a lake enhanced outflow, back to paradise climo

So much for cooler and less humid Very uncomfortable

The upper-level pattern has done wonders to really warm the waters too in recent weeks. +28C to +29C up to the NC/VA border Speaking of water temperatures, where all the people freaking out about that "cold blob" in the north Atlantic that is no longer really there

.26” overnight at home, 2.59” for the month already. I’m currently up at Mount Snow for the annual guys trip to the Brewfest tomorrow. Glorious mountain air up here today getting better by the minute. 69/62 at the closest Davis to here, yesterday was muggy with dews in the upper 60’s up here.

I expect the hottest September on record. More mid-90s next week is just about enough to seal it - especially weighted toward AC use. But let's talk about simple temperatures. A brief mid-month front may give way to yet more SER activity. We can only hope it retrogrades a bit. Otherwise - hottest September in recorded history!

Hopefully.. those waters are pretty much untouched so far..

Another .75" overnight

I am being objective.

Depends on how it behaves. 40 and mud makes me want to martyr myself.

Just in case you were wondering what the status of the 2026 hurricane season is: That is one quiet looking signal from Google Deep Mind going into mid month. If we make it to September 11 with no hurricanes (seems likely) we will break the record for latest in the season with no hurricanes in the satellite era.

September 4 1992: Early morning storms result in 3/4 to 1 3/4 inch hail in Hennepin, Dakota, Rice and Goodhue Counties. 1941: A batch of tornadoes hits Minneapolis, New Brighton, and White Bear Lake, killing six people. 1925: The third consecutive day of 95 degrees or above occurs in the Minneapolis area. For Friday, September 4, 2026 1939 - A thunderstorm deluged Washington D.C. with 4.4 inches of rain in two hours. September of that year was very dry across much of the nation, and Washington D.C. received more rain in that two hour period than most other places in the country that entire month. (David Ludlum) 1970 - The greatest natural disaster of record for Arizona occurred. Unprecedented rains caused rivers in central Arizona to rise five to ten feet per hour, sweeping cars and buildings as far as 30 to 40 miles downstream. Flooding claimed the lives of 23 persons, mainly campers, and caused millions of dollars damage. Water crested 36 feet above normal near Sunflower AZ. Workman's Creek was deluged with 11.40 inches of rain in 24 hours to establish a state record. Moisture from Pacific Tropical Storm Norma led to the severe flooding. (4th-6th) (The Weather Channel) 1986 - An unusually strong dust devil moved across the Flagstaff Pulliam Airport. The dust devil blew open the doors of the National Weather Service office scattering papers and bringing down a ceiling-mounted light fixture. (Storm Data) 1987 - Thunderstorms developing along a stationary front produced heavy rain across the Southern Atlantic Coast States. Up to eight inches was reported north of Charleston SC. Serious flooding was reported in Monks Corner SC. Seven cities in the northeastern U.S. reported record low temperatures for the date. Houlton ME dipped to 32 degrees. (The National Weather Summary) (Storm Data) 1988 - The western U.S. experienced another day of record heat. The afternoon high of 91 degrees at Stampede Pass WA established an all-time record for that location, and Los Angeles CA equalled their all-time record high with a reading of 110 degrees. A record high of 107 degrees at San Diego CA was their hottest reading in 25 years. Red Bluff CA was the hot spot in the nation with an afternoon reading of 118 degrees. (National Weather Summary) 1989 - Overnight thunderstorm rains of four and a half to seven inches drenched eastern Nebraska during the morning hours, pushing creeks out of their banks, and flooding fields, country roads and city streets. Totals ranged up to 6.97 inches south of Creston. It was also a soggy Labor Day for northern Florida. Jacksonville reported 6.82 inches of rain, and evening thunderstorms produced 2.75 inches of rain in one hour at Sandlewood.

Just in case you were wondering about what the latest Drought Monitor looked like: I think we're all GOOD !

Essentially never lose power here

The updated monthly Euro seasonal forecast as of Sept 1st is due to be released tomorrow.

0.86" of rain with a general 1" around the area from storms last night. Very welcome. It was a windy day yesterday with ENE winds and temps around 70. Same on tap today without the rain.
