it's fascinating how extreme heat was balanced out with extreme cold. the same must have happened after 1953 and 1955.

Don, in 1983 when JFK reached 100 in both July and August, what was their high temperature on 9/11/1983 when NYC hit 99? I think NYC hit 90 6 times in September that year, did JFK also hit 90 6 times that month?

we need a 2002 type pattern to have this happen more often.

Yes a few days of this is pretty nice. 4 days of this and 3 days of the other is an interesting roller coaster lol.

a characteristic of summers like 1999 was that we would have weeks without any frontal passages (this also happened in 1993) and then the drought would be broken with a tropical deluge in September after the peak of the heat had already passed. I remember 1991 was also like this, but the tropical system that broke the drought was Hurricane Bob in late August. We did have a couple more 90 degree days after that in September though.

2002 wow and that was a really hot summer (hot and dry, which we need to get extremes like this.)

I think it has happened in August before, though I don't remember what year-- maybe 1993?

I'm confused I thought he loved cold weather lol. I like short heatwaves with breaks in between of weather like we have now.

it depends on how it's communicated. If a change in the weather exposes a weak immune system then it's possible. Generally speaking, viral infections are more contagious in cold and dry weather because virus particles stay in the air longer. Conversely bacterial infections are more common in the summer because bacteria love warm and humid weather.

unfortunately it also means less extremely hot days so our climate is becoming compressed to higher mins and less high temperatures of 95/100 or more. 1949 must have had lower low temperatures to balance out the 8 high temperatures of 100+ at EWR and 5 high temperatures of 99+ at NYC.

What I see on the hourlies is that the sun comes back out at 2 PM and thats when the temperature spike occurs. As a matter of fact they have me completely clear at 5 PM. Tomorrow looks like the really cool day and cloudy all day with a high of 72. It's 76 here now with a forecasted high of 81 here. Sunday looks to be partly sunny here now and no rain at all and a high of 86.

I think 1993 and 1999 were in drought patterns too weren't they Chris? We had much drier summers back then. July 1999 was one of the hottest months I have ever experienced. July 1993 right up there too.

it could have reached 99.5 at least in between hours.

Maybe this will cycle back to more 40s-60s type long heatwaves? If not that, maybe a 1993 or 1999 type heatwave (which is still relatively recent), 1999 had two very long super heatwaves and the one extreme heatwave in 1993 really stands out.

I think this week demonstrated that Long Island can be just as hot as New Jersey if the ridge is strong enough. This intense heat was like what we had in 2011. The heat we have had since then wasn't strong enough to overcome the ocean like this one was. 1988 the heat wasn't nearly as intense as what we had in 1993 or 1999 or 2010 or 2011 or what we just had now.

But less heat for us on the coast in 1988? 1999 was much hotter here

10 consecutive 100 degree days? do you think it's possible here?

those droughts are why the summers of 1953 and 1966 have never been matched for 100+ heat

the really hot summers began with 1944, the 1944s and 1950s were a cut above everything that happened before and since. And a few of the 1960s, like 1966, has never been matched.

it's mostly minimum driven, the highs and lows have become compressed

August 26-28 had an extreme 3 day 100+ heatwave though

post August 20th 100 degree heat is very rare which is why the super heatwave in August 1948 and August - September 1953 are so notable. As is the August 20, 1983 100 degrees at JFK and the 99 on September 11, 1983.

Thanks Don, I got some clarity on this page (it coincides with the 2 straight 100+ days that happened at JFK during the same period. https://www.weather.gov/okx/100degreedays The only two periods of three consecutive 100+ days at NYC were in 1948 and 1993. Both times JFK had two consecutive 100+ days. NYC has had multiple separate heatwaves that peaked at 100+ on a few occasions. 1944 (two heatwaves in August), 1949 (once in July once in August), 1953 (July and August-September), 1954 (two heatwaves in July), 1955 (one in July and one in August), 1966 (a whopping three separate heatwaves that peaked at 100+, one in June and two in July). And that was the last previous time it happened, NYC has not had multiple heatwaves peak at 100+ since the 3 heatwaves that did it in 1966. More recently, JFK had two heatwaves peak at 100+ in 1983 (one in July and one in August and another one that peaked at 99 in September.) That was the only time they had that.

we're so used to cloudy / rainy weekends, today feels like a Saturday

now 74 here, it's dropping slowly but the best thing is that wind is cooling down my house.
