June 27, 1966, is that the earliest 100 degree temperature recorded at NYC? So next week we have the potential to have our earliest 100 degree temperature at both NYC and JFK?

incidentally that 1 99 degree day in 1969 is the earliest on record, with a high of 99 on May 29, 1969, I think it's pretty crazy that the record high for both May and June is 99, it shows that June has the potential to be hotter than 99 and we're overdue to break that June monthly record at JFK (which was tied 4 times).

Yes, JFK exceeded NYC by 5 degrees on that day and yet no one seems to remember it (except me)-- that day really stood out to me.

It's a few days and if you can read I said we would still get some hot days.. that 82 was a joke if you can understand that.. but yes I still think it's Midwest and west after this

The hilarious thing about JFK is they hit 99 4 times in June but not 100 (not yet)..... the other hilarious thing is they also hit 99 once in May, on May 29, 1969.... which shows that not only is 100 possible in June at JFK, it's also inevitable. Let's see if this is the June that will do it. Having the same record high for May AND June is not something I would expect to last..... Regarding NYC, what I find so ironic is that the record highs for next Monday and Tuesday (both 96) are from 1888....... This is the earliest extreme heat we have seen since 2012 when we were in the upper 90s around this time around the entire area (including JFK).

Yes. I fixed my post as I accidentally omitted 1983 and 2010.

Just as I'm skeptical of hitting 100 on any given day because any random thing can screw it up, I'm also skeptical of models wanting to blow a sea breeze all the way to Meriden lol. I think there will be some breeze along the coast, especially SE CT, but I doubt it gets terribly far inland. I have been most cautious on believing we maximize potential with this heat wave, but I think I'm on board now. This looks like it could be the real deal. It's 100 or bust, and if we can get two consecutive days that'd put us in rarified air. At least here in central CT. Even if we can't get a 100/62 heat indices are likely to be impressive. We better not fumble at the 1yd line

we have the opportunity to have the earliest 100 degree temperature at both NYC and JFK next week.... not sure what NYC's record is but I think it's from 1966 Tony? Was it earlier than the extreme heat we will have next week?

Perhaps. Let's say the temperature rises 1.5C to 2.0C from the 1991-2020 average. That would mean, 87°-89° days during 1991-2020 would then be 90° days, on average. That would increase the average annual number of 90° days as follows: JFK: From 10.8 to 22.8; LGA: From 21.8 to 37.9; NYC: From 17.4 to 32.9; Newark: From 28.3 to 46.8. Extremes increase in non-linear fashion, so that actual incidence would probably increase somewhat faster than overall temperatures. So, it seems plausible, but that's far out.

2010: Jul 4 High temperature JFK: 101 EWR: 101 LGA: 98 ISP: 97 NYC: 96

Be safe everyone. Heat stroke comes on quick.

75 already here, off a low of 56

Thanks Tony, that's exactly how I remember it too.

The high of 101 on July 4th at JFK, was 4 degrees higher than Central Park if I remember correctly and also higher than LGA. I think EWR was the only other official ASOS in the area to reach 100 on that day.

2010 has the station record for all these locations, Tony?

will be a nowcast, I wouldn't rule out something. A few mesos kinda hit on EMA from here down to your hood, to the Cape. (as you probably saw)

JFK 2010: Jul 4: 101 Jul 6: 101 Jul 7: 100

Models seem to be hinting at a sea breeze of sorts pushing through Monday? Thereby limiting the high end heat. Tuesday is pure heat though lol

also for 100+ days I think the record is 4 from 1953 and 1966 at NYC? and for 100+ days the record is 3 from 1966 and 2010 at JFK?

Pretty steep temp rise here this morning--11 degrees in two hours. Should be a nice day.

Thanks Don..... in 2010 JFK also had 3 days of 100+ July 4th, July 6th and July 7th, if I remember correctly? (so three days out of four?) The 3 days of 100+ in 1966 at JFK were all consecutive?

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, 1983 and 2010 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.
