too bad no rainbow

what was the peak of the 1901 heat event in NYC Roger?

It might have been more than just the 1960s though as it seems the 1940s, 1950s and 1970s were also quite dry, Chris. So what California has been experiencing over the past decade is what we experienced back then? That's what I mean by cycles, that has to flip at some point.

The extreme heat has been isolated to the Newark area (and only in a few select summers like 2021.) Basically what I'm looking for (as far as Newark is concerned) is at least 40 90 degree days and at least 3 100 degree days. For this area, at least 20 90 degree days and at least 1 100 degree day. NYC somewhere in between, 30 90 degree days and 1 100 degree day.

That's just this summer, I'm talking about the entire period after 2013 has been pretty mediocre, this is the first great summer since that historic period ended.

Thats why the 1950s were so magical and have not been matched since. Also, 1944...

He is just channeling his last name lol

Good, I want 1983 to be the top analog. September 1983 has never been equaled.

when I was a kid 100 degree temperatures felt special. they still feel special ha

June 2025 has the hottest weather I've experienced since 2011 and 2010. Didn't get all that hot here in 2021, that was an inland hot summer

record dryness is also historic.... getting completely shutout of rain last October was momentous!!

That was the hottest summer I've ever experienced here and hot from beginning to end (we even had upper 90s in early September.)

a classic bookend winter, Ray.

I miss my dry hot summers. Last week was good but very shortlived. The more it rains the more harmful bugs we get and the taller the weeds are. More spraying becomes necessary to eliminate both.

Someone needs to do a study of the 50s to find out what was causing all those 100+ degree temperatures, all those extremely long heatwaves and all those east coast TC landfalls and even a few powerful tornadoes thrown into the mix!!!

yes that moisture has curbed our triple digit heat...until this summer!!!

Yes this is exactly what I've been saying. As a matter of fact I'd go further and say this is the first time we have seen this kind of heat since 2013 and in reality since 2011.

Do you think the extreme heat we have seen this summer for the first time since 2011 is due to the strong el nino we had 2 years ago Chris?

Yes, that's the way we are getting higher average temperatures. High temperatures are going up too, but at a slower rate than low temperatures. I think at some point the high temperatures will flatten out depending on how close you are to the ocean. For example, JFK's average high temperatures will probably flatten out at under 90 but higher than 85 (based on the temperature increase data I've looked at.) While EWR's average high temperatures will probably flatten out at under 95 but higher than 90.

And several more 90 degree days, JFK is out to a similar lead that they had in 2010. Do you think Central Park should have broken its all time 90 degree day record in 2010 just like JFK, LGA, and EWR did and perhaps even have had more 100 degree days, Don? It would be interesting to do a reanalysis of Central Park's data from 2010 to see if they should have broken the records they set in 1991 and 1993 of 39 90 degree days.

it's amazing how dry 1941-1970 and secondly 1951-1980 were compared to the 30 year periods that came before and after those two periods. No wonder they had so many 100 degree days and 7+ day heatwaves.

Thanks Don, so the rainfall amounts are still rising even compared to the 1990-2020 period. From 2.41 days per week and average total summer rainfall of 13.69 inches to 2.42 days per week and 13.99 inches of average total summer rainfall for 1995-2024. At this rate the 2001-2030 period should be the first one that averages 14.00 inches of average total summer rainfall. Something else I noted from your graphs, is that although the 1911-1940 period peaked with 2.45 rain days per week, it only averaged 12.42 inches of rain per summer. The driest period was 1941-1970 which was also during our big heatwave/100+ degree bonanza period of the 1940s, 1950s and 1960s (not a coincidence) when we averaged 2.17 rain days per week and only 10.64 inches of rain per summer. The dryness probably led to the extreme heat and longer heatwaves of that era. There is no other 30 year period that comes close to matching 1941-1970 for dryness and the second driest period came right after it, 1951-1980 with 2.21 rain days per week and 11.03 inches average total summer rainfall. All the other periods are near 12 inches of total summer rainfall or above.

Yes, it's completely out of range compared to the other reporting stations. But the wetter climate might be shortening the length of heatwaves and also limiting the frequency of 100 degree temperatures (compared to how frequent 7 day heatwaves and 100 degree temperatures were during the 1990s for example.)

But what about these fronts stalling near the coast, something we really did not see at least in the month of July in summers like 1991, 1993, 1999, 2002, etc (basically the summers with the longest heatwaves since 1953.) From what I remember of 1993 and 1999 and 2002 especially, the fronts always died out before they made it into our region (at least in July.) This enabled us to have extra long heatwaves without being interrupted with days of rain.

also much rainier summers and shorter heatwaves, something which I outlined in an earlier post.
