I remember a 4th of July overnight period sometime in the 90s where Central Park station was 91 F at 1:30 AM. There was a power warning in effect. Guess they issue those when the grid is in danger of collapsing. .
Interesting also that the band of heaviest snow is almost exactly parallel to ( but about 50 miles south of) the path of totality of the eclipse in 2 weeks. .
