I read (I think from AI.... so not sure if this is accurate) that by 2080 we will see a much steeper rise in extreme heat and our number of 90, 95 and 100 will all double from where they are now, do you think that could be accurate, Don?

JFK Airport 1949: 2 days 1993: 2 days Most in any year: 3 days in 1966 Central Park 1949: 5 days (highest on record) 1993: 3 days Most in any year: 5 days in 1949

Nice, why does 1948 have a yellow square around it, is that because 1948 is the start of the dataset for JFK, Tony? I know all 3 of those in 2010 were 100+ All 3 in 1966 were also 100+ The 2 listed in 1993 were also 100+ The 2 listed in 1948 were also 100+ The 1 from 2013 was 100.

Even as it is inland relative to NYC, Newark is still on the coastal plain. SSTs are affecting ridge development and placement. The rising moisture may have slowed the rise in high temperatures, but as the climate warms further, the 1949 and 1993 records for 100° days at Newark will likely be broken (perhaps in the next 15 years?). That the climate in the Northeast has grown wetter also has an impact. Both summers were among the driest on record for Newark. The climate models don't do as well on a regional or local basis.

for it to be prolonged we need to match the 7+ day super heatwaves we had in the past (sometimes multiple in the same summer). Our longest heatwaves are still from 1944, 1953, 1993, 1999, 2002, etc. It will probably happen eventually, but it hasn't yet. Even this upcoming heatwave is the typical 4 day one.

Updated 90 degree days by season 2010 - prsnt

Can you include JFK in this list too, Tony? I know they had 31 90 degree days in 2010 , 10 95 degree days and 3 100 degree days (one more than NYC.)

Yes, I wonder how many official NWS ASOS locations measure their temperatures in a park?

Tony do you have a list for JFK and NYC in terms of 99 and higher? I know 1949 takes the number one spot for 99+ temperatures at NYC with 5, not sure what is number 1 for JFK, but I know they have the same number of 99 degree temperatures (19) that they have of 100+ temperatures (also 19), which I find absolutely amazing.

The issue with central park is it being a mecca for the NYC region as a whole and the perception isnt truly representative of the urban/city metro areas. Head lines first 100 possible since 2012, first 90 degree day , hottest in years when many other sites have been hotter recently and have 90 degree days already this year. TTN seems to be running lower than prior years but i havent looked to deep into it.

I loved 1993 I consider that my hottest summer on record in terms of how hot it felt (2010 was much drier), so this matches my experience. I see 1988 up there and it matches 1949 for second place, I came back from a long overseas trip in August that summer and my house was like an oven when I got back. Good to see 2022 in a tie with 1953 and 1999, two other historically hot summers with very long heatwaves.

Yes 2022 was extremely hot no doubt, but we still have not been able to match 1949 or 1993 for extreme heat so it makes me wonder if there is a natural limit to how hot it can get. Obviously if we keep warming on this trajectory whatever those thresholds are they will eventually be passed.

a few days ago NYC exceeded LGA by 1 degree. Fortunately some of us have excellent memories and remember these things.... also what was going on in July 1966 when the temperature at NYC was only 103 and LGA was 107 and JFK was 104 and EWR was 105? Were those foliage issues too? Temperatures in a park will be cooler, with or without foliage issues, folks....

The really interesting thing about inland areas, let's take Newark as an example, is that they have never matched the number of 100 degree days they had in 1949 (8) or 1993 (9). I wonder if there is a ceiling to how much CC can affect inland areas for summer maxima too Don? Factoring in the additional amount of moisture added to the atmosphere because of CC, there might well be.....

Monsoon climates have a secondary maxima in September, Chris. I know, because in my travels around the world, I've experienced these climates. They have a primary maxima in May and June and a secondary maxima in September and October.

Yes. It can happen, especially with an offshore flow. July 23, 1972 is a great example: JFK: 100; Central Park: 94.

and yet in early July, JFK exceeded Central Park when it hit 104.

It was a joke because Sundog can't handle it lol. Plenty of personal stations though were 82, but we throw those out.

we haven't matched the heat of the 2010-2013 period or how widespread it was, look at this amazing 2012 heat we had in June LGA: 98 (2012)JFK: 97 (2012)

Long range GFS and ECMWF have warm / humid both currently have early storms.

That's correct, what the people with reading comprehension issues missed is that I specifically referred to extreme summer high temperatures. And there is a reason why that hasn't happened and that also has to do with climate change, namely that adding more moisture into the atmosphere makes it much more difficult to pass previous record highs in the summer. It's basic physics folks.

That is why I never ever hang a hat on Suckuweather forecasts

well excuse me for hating on the sun rising at bloody 5:11am... I like long dark nights where I can properly sleep
