The Midwest, however, will continue to scorch on Saturday, with excessive heat warnings remaining in several states, including Iowa, Illinois and Indiana. In Fort Wayne, Ind., temperatures could reach 106 degrees, but feel more like 114.
Temperatures in Philadelphia and New York have reached the high 90s recently, but haven't crossed 100. Forecasters predict a temperature of 102 degrees in Philadelphia on Saturday and around 100 in New York.
The New York City Health Department is urging residents to take precautions and to check on vulnerable neighbors. The department issued a reminder Friday that serious illness can result from the heat.
