At least at KNYC we exactly matched 1972 for first 90 degree day. I will point out that in those days KNYC had less vegetation and the high that day was 91. So in real world this first 90 day was probably a hotter day than 1972.

Any chance we don't go over 90 this summer? I know that in Niño summers August tends to run cool.

How do things change if this El Niño fails, similar to 1977 (started later) and 1980? Joseph D'Aleo once had a piece on failed Niños turning into fairly robust summers.

Why only one cold-phase analog, 1957?

It wasn't done yet.

Did all that and more today, long after 8/20.

We went as far as early October, 1927 (a year where all 90's were early and late) for 90+ weather. And we came close in 2007 and again last October, on, I think, October 9.

1969, 1972 and 2009 sure broke that pattern.

I was going to ask about 1952-55.

Not sure if the post in question (about 90 after midnight) but I think it may have happened 7/14-15/1995. I recall the temperature dipping to 84 around 9 a.m. in a brief shore before going over 100. That heat wave ended in the famous derecho in upstate NY. Edit. I was right, at least at LGA (link). It was around 90 at midnight. I remember seeing that also on my home thermometer when I came back from my 20 year High School reunion that night. We didn't pick up a 90 degree day though since that day, July 15, it made it to 102, and July 14 had a high of 98. It was under 90 by the wee hours of July 16.KNYC's reading was not available.

it's on the list... I'm surprised 1999 isn't there.

1955 had no 100+ days in KNYC. It had a record or close to record number of 95+ days.

I'm surprised that 1953 following 1952 isn't in there. Or 1971 following 1970. Or 1974 following 1973 (not that the latter would have helped). Edited to say I went back and checked links. The summers I mentioned were just barely under the 25 threshold. Still, for example, 1970 and 1973 summers were memorable, albeit concentrated in August/September.
