Having so many 95° or warmer days this July, it would be a oddity for LGA not to reach 100°. With the heat in the forecast, LGA could finish in 2nd place for the most 95° or warmer days in July.

ISP is the closet that our area has come to an 80° dew point this year. MacArthur/ISP PTSUNNY 78 78 100 S3

70° minimums have been more impressive than 90° maximums at JFK since the record dew point surge began with the 2015-2016 super El Niño.

Pretty impressive marine layer for such a warm air mass.

Yeah, your area is closest to the marine layer again today. ISP starting the day with a 76° dew point and dense fog in the Hamptons. MacArthur/ISP PTSUNNY 76 76 100 SW8 29.98R FOG East Hampton FOG 72 72 99 SW6 29.99R VSB<1/4

84/72 here along the South Shore.

Higher dew points holding on along the South Shore. 84/72 in Wantagh. Some fog coming ashore now in the Hamptons.

Yeah, the really impressive record high temperatures in recent years have come during the cold season. The new all-time monthly highs of 96°in October 2019 and 80° for February 2018. We have been lucky that the most extreme high temperatures haven’t been in July or August. But we saw that 108° new all time high at Newark in July 2011.

JFK came close on 7-21-19 with a 114/89 high and low on the heat index. https://mesonet.agron.iastate.edu/plotting/auto/?_wait=no&q=153&network=NY_ASOS&zstation=JFK&month=jul&var=max_feel&dpi=100&_fmt=png

Euro maxes out temperatures Sunday and Monday with the highest dew points Monday. Also has convection along a weak front on Monday. Should the convection and clouds hold off, then temperatures and heat indices would be higher Monday.

The minimum temperature departures to our north this month are pretty impressive, BTV...+6.1 ALB...+7.0 POU...+5.8 LGA....+4.8
