Meanwhile on Friday, the heat continued to oppress Philadelphia. The city was under an excessive heat watch, with temperatures expected in the lower to middle 90s, Lefevre said.
And New York City will be a steamer. A heat advisory remains in effect until 8 p.m. Sunday for all five boroughs. Temperatures are expected in the lower to middle 90s, the National Weather Service shows.
Cooling centers will be open Friday through Sunday throughout the city, New York City Office of Management spokesman Nancy Greco said. Public areas with air conditioning, such as senior centers and libraries, will house cooling centers for those who don't have air-conditioned homes, she said.
New Yorkers can call 311 or go online to find a center near them.
