Not sure why anyone thinks rain on Sunday impacts our highs in Tuesday. A theory floated by some experienced posters as well. Bizarre 

I don't believe today's light rainfall (0.10" at NYC, 0.08" at LGA and JFK, and 0.06" at Newark) will have much impact on Tuesday's high temperatures. Looking back at Central Park's long record, there were 6 100° days two days after measurable precipitation. In fact, on July 20, 1977, 0.06" rain fell. July 21, 1977 saw the mercury hit 104°. 

The most precipitation that fell two days before a 100° high was 0.36"; the most precipitation that fell one day before a 100° high was 0.16".

The highest temperature two days after 1" or more rain was 99°; the highest temperature one day after 1" or more rain was 97°. 

The highest temperature two days after 2" or more rain was 95°; the highest temperature one day after 2" or more rain was 93°. Both those cases followed 3" or above rainfall.

The highest temperature two days after 4" or more rain was 89°; the highest temperature one day after 4" or more rain was 87°. 

In short, heavier rainfall would have an impact. The light rainfall that occurred today shouldn't have much impact. The development of a sea breeze, cloud cover, and/or humidity will have a larger impact.
