The extreme heat was confined to two days in June, the rest of the summer has been mediocre.

I think we could turn that around a bit either later in July or in August. More likely in August.

Anecdotally, the atmosphere seems thicker and more "vaporous" than it did decades ago. More Venusian might be a good way to describe it. In my hometown, the normal July minima used to be in the 50s, but now reaching the 50s there is like a big achievement in the month of July. Normal lows from decades ago are now seen as a nice break from the heat. Very weird to see in the absence of any UHI increases. All very bizarre.

Yes the thicker more polluted air is why the highs are more muted except for those 2 days in late June

That would be a nice change, hopefully it's a drier heat

Eventually I think there's a chance of that. More likely later on.

yeah more water vapor in the atmosphere is actually worse than more co2 in the atmosphere

 

The warming atmosphere from excess CO2 holds more moisture for these extreme rainfall events.

Water vapour: the invisible amplifier of global warming 

In 2024 the atmosphere held more moisture than previously recorded by a large margin. Total column water vapour—the total amount of moisture in a vertical column of air extending from the surface of the Earth to the top of the atmosphere—reached 4.9% above the 1991–2020 average, far surpassing previous highs in 2016 (3.4%) and 2023 (3.3%). 

Water vapour is Earth’s most abundant greenhouse gas, responsible for about half of the planet’s natural greenhouse effect. Unlike other greenhouse gases such as carbon dioxide (CO₂) and methane (CH4), the concentration of water vapour in the atmosphere is not directly influenced by human activities. However, water vapour concentration rises as the atmosphere warms: for every 1°C increase in atmospheric temperature, air can hold 7% more moisture. This creates a vicious cycle—warmer air absorbs more vapour, which traps more heat, further accelerating warming.   

 

 

Annual anomalies in the average amount of total column water vapour over the 60°S–60°N domain relative to the average for the 1992–2020 reference period. The anomalies are expressed as a percentage of the 1992–2020 average. Data: ERA5. Credit: C3S/ECMWF. 

 

 

“Water vapour is both a consequence and a driver of climate change,” explains C3S Director Carlo Buontempo. “In 2024, we saw this feedback loop in ‘overdrive’. Higher sea surface temperatures intensified evaporation, whilst warmer atmosphere allowed more water to be held there as vapour, adding ‘fuel’ to several extreme weather events.”   

The consequences are potentially disastrous. Increased atmospheric moisture can intensify storms and increase the intensity of the most extreme rainfall. The atmosphere knows no borders, so the potential effects are

Record high minima tied at Bridgeport (73F) and Islip (74F) yesterday. Not even record-breaking rainfall can flush out this unbelievably resilient heat. Elkins, West Virginia also saw a record high minimum tied (69F), while Concord, New Hampshire, Burlington, Vermont, and Beckley, West Virginia, each matched their 2nd warmest low temperature for July 14. Pittsburgh, PA, Charleston, WV, and Huntington, WV all matched their third warmest low for July 14. There would have been additional records, but unfortunately, several places were unable to retain their heat through 1 am EDT.

It will be interesting to see this time since we usually don’t get widespread 100° heat after these major flash flood events. This has been very monsoon-like during recent summers. First we get the widespread 100° heat followed by a 5”+ or 10”+ deluges.

Looks like it made it down to 68F at Elkins this morning, 2F below the record high minimum set in 1916, so they will end their record high minima streak at 2 days.

The 2025-26 ENSO thread covers this quite a bit. I agree and it’s been documented by Bluewave especially how this marine heatwave east of Japan ruins our winter storm setups. And looks like record heat there again. Hoping for an active typhoon season with lots of recurves into that area, maybe that’ll help a little but my hope for winter is very low with that warm water still there. It hypercharges the Pacific Jet which is the opposite of what gets it done here.

We need to remove both CO2 AND water vapor from the atmosphere, we're in an emergency situation and removing CO2 or stopping fossil fuels (which won't happen in our lifetimes) won't be enough, water vapor needs to be taken out of the atmosphere too.  And with the melting of the ice caps the emergency will only accelerate.

where? I saw a report of 0.88 on the south shore in Nassau County and 1.09 inches at JFK, there was a report of 2.09 inches in southern Queens, we definitely got much more than 0.5, maybe less in Suffolk County, but we had a lot more than that here.  I saw large puddles and even flowing water on my street between 7-8 am when it was still raining hard.

I still don't see a vehicle to significantly weaken storms when the SST have rapidly warmed into the mid 70s now.

1995: Upstate New York: A extremely severe derecho sweeps across upstate New York. Wind gusting to 106 mph devastates over one million acres (400,000 hectares) of trees, felling tens of millions. Five campers are killed by the falling timbers.
(Ref. WxDoctor)

1995: Danbury, Connecticut: The highest temperature ever reported in Connecticut is 106 °F. (Ref. Lowest and Highest Temperatures for the 50 States)

1995: Dew points >80 degrees, with a date record high of 103 degrees gave Philadelphia, PA a heat index of 129 degrees. 40 people died from heat in SE PA; approx. 1 million PA chickens succumbed to the heat. Some highways (including I-83 in York County) closed due to heat buckling. (Weather Guide Calendar with Phenomenal Weather Events 2011 Accord Pub. 2010, USA)

I distinctly remember both Danbury and Poughkeepsie reaching 106 matching the heat in Chicago, we had a sea breeze so we did not reach triple digits here.  This summer, while it had a very hot few weeks, was not on the same scale as 1993 or 1999.

 

1936: Perhaps the hottest night ever recorded in the US outside of the desert Southwest, occurred at Lincoln, Nebraska when the minimum temperature fell to only 91°F. The citizens of that city spent the night outdoors trying to sleep on the lawn of the state capitol. (Nebraska State Historical Society) (Extreme Weather p. 30, by Christopher C. Burt)


1936: All-time record highs were set at the following cities: Quincy, IL: 114°, Peoria, IL: 113°, Lincoln, IL: 113° and Rockford, IL: 112°. Champaign, IL hit 107°. This stood as their all-time record until 1954.

 

wow this was the kind of summer the CONUS has a whole has never seen since..... 1936

 

1954 - The temperature at Balcony Falls, VA, soared to 110 degrees to establish a state record. (The Weather Channel)

wild to see anywhere on the east coast hit 110....

 

Highs:

EWR: 104 (1995)
NYC: 102 (1995)
LGA: 103 (1995)
JFK: 99 (1983)

Exceptionally hot day, I was in the Poconos on this day and it hit 100 there too.

1983 was a hotter summer for us though and hit 100 multiple times here both in July and August.

 

Sure, 110 in Virginia on July 15, 1954. What a joke. It's 10 degrees warmer than all of its next day neighbors. Absolute rubbish. It was a hot day, absolutely. With some 100s, the second highest reading (also a little suspect, given the nearby 92) was 106. But this 110F reading is absolute fantasy. It's also nowhere near the East Coast, BTW.
