Per NWS, dewpoint here drops to 67 tonight, then back to 70 saturday afternoon and then 70+ into next week. 67 is better than 77, but its not really a "break".
JFK, FRG and ISP all had 103 earlier, i presume even higher between hours, and they are further south than me. No doubt in my mind much of Western/Central LI were over 105 for a time today.
90/77/104 at ISP (down from 91)
91/74/100 at FRG
92/76/104 here
Thats a record high for ISP, not sure about FRG.
Excessive Heat Warning should have been issued, as Heat Index is 104+ in spots now.
