But that heat won't move east from there unfortunately. July 2010 was much hotter here, as was July 1999 and July 1993 before that.

Yes it's still raining lol

it's low, around 20% probability.

Yes, but most of those are from the 2010-2013 period though which is when we had a bonanza of 100+ days. That 2019 period was very memorable for having the highest heat index (117) that JFK has ever seen.

It wasn't supposed to be raining here after 12 noon but it is and raining pretty hard too. I see the projected clearing line has been pushed back from 3 pm to 8 pm so we might clear just in time for sunset (it would make for a gorgeous sunset if that happened.)

Looks like the south shore might be near 90 on Thursday too, so far my projected high is 88 for that day.

Did you ever have a situation where JFK was cooler than Long Beach, Chris? It does happen to me quite a bit, I just chalked it up to living in a more urban environment than where JFK is located. What's the height at which the higher stations run cooler than 2m? Would a sensor on or near the roof of a 2 story home be significantly cooler than a sensor at 2m? 2 stories = 20 feet or approximately 6m.

An example from yesteryear. In July 1993 (on the 9th if I remember correctly), I recorded a high of 102. JFK recorded 101. This was in the era before ASOS and the numbers matched.

Chris, we've had a 20 day heatwave? It must be at Newark since our longest heatwave was in 1953 and September's all time record high (102) is from that year. 1953 was historic for number of 100+ days (4) and length of heatwave (12).

Hopefully an increase in 95 and 100 degree days too even with onshore flow (with higher SST.)

I like rooftop stations I think they more accurately reflected the true climate rather than these ASOS stations. I've had thermometers (both digital and liquid) since 1986 and my temperatures matched rooftop stations more accurately than these ASOS stations. An example from last Saturday. I'm about 5 miles east of JFK. We cleared out at 4 pm and were clear until 6 PM. JFK ASOS reported *mostly cloudy* the entire time. When the skies cleared out our temperatures got a nice boost into the mid 80s. But JFK flatlined around 75 degrees. We were 10 degrees warmer than JFK at 85! Now, some might say, exposure to sunlight caused a higher reading for me, except my inside thermometers also experienced a boost well away from any sunlight and matched my outside sensors (plus I keep my temperature monitoring sensors on the north side of my home.)

I've noticed a high number of ants outside my house, and I've read reports where there is a lot of flash flooding in the South there are a lot of ants, fire ants are a HUGE problem there. So this is something else which is now overpopulating.

I thought Watts Up With That is a climate change skeptic site though?

and even this Wednesday-Friday period with sunshine will have interference from wildfire smoke. This is an annual thing now!

Thanks Chris, can you show 95 degree days at JFK, are those flatlining like 90 degree days are?

Don't the higher number of 85 degrees point to a more true tropical climate, there a lot of cities near the Equator that have this kind of climate, and also a lot of bugs-- ticks, spiders, mosquitoes, parasitic flies like the Tsetse Fly, leeches, etc. Are we going to start seeing exotic vermin on our shores and in our homes soon? These bugs do not like extreme heat, what they want is warm overnights, very humid, very wet and frequently cloudy weather. That's what a true tropical climate gives them.

In some way shape or form we're going to have to get rid of all this excess moisture from our atmosphere. It's the only way to counteract rising sea levels and save our coastlines too. Some of this thinking is sci fi but there's a lot we can do, including creating machines that will remove water vapor from the atmosphere and convert it to drinking water as well as transporting water to future space colonies on the Moon and Mars (that water will have to come from somewhere and taking it from Earth will benefit both us and them.) Removing excess water vapor from the atmosphere is more important than removing excess carbon dioxide from the atmosphere, water vapor is the much stronger greenhouse gas.

I think that was the year or it could have been 2010? I'm not sure.

2009 to 2018 was ideal for big snowstorms in the winter and extreme heat in the summer with TCs thrown in during the fall. The ideal weather patterns for us. We don't get any of those things anymore lol.

Have you noticed that the return period for 100 degree days has been getting longer at JFK too? Back in the 40s, 50s and 60s it used to happen every few years and now it's only once a decade or so. It's even getting longer at NYC, during the 40s and 50s, I think they got 100 degree days every other year, which is even more frequent than what I experienced in the 80s and 90s before the sensor issues cropped up. It's probably because our climate becoming more humid is making it more difficult to get higher temperatures in the summer (so a combo of a wetter atmosphere, a wetter ground and onshore flow.) The summers between 1944 and 1955 and then 1966 were chock full of records that haven't been matched since. 1944 had a record heatwave of 8 straight days of 8+ days in August and a separate 7 day heatwave in July. 1948 had 3 days of 100+ at JFK (later matched in 2010) 1949 had 5 days of 99+ at Central Park 1953 had that record 12 day heatwave at Central Park and another heatwave of 9 day length and 4 days of 100+ split between those two heatwaves (including the highest temperature ever recorded in September, 102). 1955 had a record 16 days of 95+ 1966 had 4 days of 100+ at Central Park, in both June and July. July 1966 had the highest temperature ever recorded at LGA (107) and JFK (104).

Yep the number 1 thing we need for extreme heat is low rainfall lol. 2011 kind of bucked the trend there so maybe if it dries out for 2 weeks we can reset the pattern? July 2011 had the most extreme heat (although it didn't last long) that I've ever seen here. My personal weather station hit 105.6 which is the highest I've ever seen here. That also came after a la nina.....

I guess you could call it a flash drought, I've noticed these are becoming more common. I liked that we finally got a month with zero rainfall lol.

That's a good way to put it Don. Warm to very warm vs hot, which has a specific definition that involves number of 90+ days.

just one of many reasons why excessive rainfall is horrible (higher number of mosquitoes too.) time to start spraying soon.

thats not a hot summer though, above average driven by higher minima is a warm to very warm summer but doesn't fit the specific definition of *hot* which is defined by number of 90, 95 and 100 degree days.
