To be fair, summers should always be judged by number of 90/95/100 degree days.

of those, 2010, 1999 and 2025 (so far) are looking pretty good.  The others were boosted by elevated minimums.

It’s possible that the 103° recoded out at Baiting Hollow could be the new all-time high for any month on Eastern Long Island.

That still remains one of my all-time favorite snowstorms. Probably the most electrified blizzard. The record cold and snow in April 1982 would have been impressive in the 1880s or 1780s. 

[Rjay]

Another NW wind day with a late afternoon 90 here.  91 currently  

[steve392]

89 and a strong sun today.  Even with breeze it was blazing. 

[donsutherland1]

The temperature soared into the lower 90s in many parts of the area today. Today was also the second time this year and 18th time overall that Central Park did not reach 90° or above when Islip, JFK Airport, LaGuardia Airport, and Newark reached 90° or above. 17/18 (94%) of those dates have occurred since 2000 and 12/18 (67%) have occurred since 2010. Prior to 2000, 0.6% of days with 90° or above highs at Islip, JFK, LaGuardia, and Newark did not reach 90° in Central Park. Since 2000, 10.1% of such days saw a high below 90° at Central Park while 10.6% had no high of 90° at Central Park since 2010.

Very warm weather will prevail through mid week. New York City will see highs in the upper 80s. Newark will likely be near or just above 90° on each day during this period. 

Excessive heat does not appear likely to return through at least the first week of July. However, there is somewhat less certainty than yesterday. Both the 0zz GFS and ECMWF show potential for more significant heat during the July 6-8 period. 

The ENSO Region 1+2 anomaly was +1.0°C and the Region 3.4 anomaly was 0.2°C for the week centered around June 18. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.47°C and the ENSO Region 3.4 anomaly has averaged -0.03°C. Neutral ENSO conditions will likely continue through at least late summer.

The SOI was +2.81 on Friday. 

The preliminary Arctic Oscillation (AO) was +1.405 today. 

Based on sensitivity analysis applied to the latest guidance, there is an implied near 100% probability that New York City will have a warmer than normal June (1991-2020 normal). June will likely finish with a mean temperature near 73.2° (1.2° above normal).

The only comparable snowstorms I can think of occurred in the 1870s.  I wonder what caused that snowstorm and cold so many decades after the planet had already started to warm?
