I drove back from the beach today, and my car thermometer which is pretty accurate (have checked it against reliable stations and it’s usually within a degree) was between 98-102 from just before the bay bridge all the way to takoma park on the beltway. Was 100-101 around Annapolis.
Dewpoints approaching 80 in the lower Hudson valley, seeing a bunch of 78’s and 79’s around Yorktown, mahopac, and Ossining. That’s like gulf coast level humidity.
