— Boston, New York City, Philadelphia and Washington, D.C., were among the cities expecting record heat on Thursday, but they're not the only hot spots around. Humidity will make it feel like 110 degrees in parts of the Catskills and Hudson Valley. And then there's Arizona, where some areas could reach 114 degrees.
For the Northeast, the 30 million people who saw the heat move in Wednesday will feel even warmer temps before it cools off.
"You ain't seen nothing yet," Al Roker, NBC TODAY show's meteorologist, said Thursday morning. "All along I-95 this heat is going to be relentless."
Cities that could set records for a June 21, he said, include:
Relief, Roker said, will move in Saturday, when temperatures should be 10-20 degrees cooler.
American Idol hopefuls in Newark, N.J., got a bit of a break from the heat, the Associated Press reported. They were ushered inside Newark's Prudential Center on Thursday morning to register to audition.
Heat advisories are in effect across the Northeast until then, and farther inland the situation isn't any better.
"Excessive heat warnings" were issued for the mid-Hudson Valley and southeastern Catskills in New York. It should feel like 105 to 110 degrees there on Thursday, the National Weather Service said.
The same warnings were issued for parts of Arizona "where high temperatures are expected to reach 110 to 114 degrees," the weather service stated.
Wednesday's records included: Newark, N.J. (98), Hartford, Conn. (97), Burlington, Vt. (95), Massena, N.Y. (92), Binghampton, N.Y. (90) and Houlton, Maine (90).
In Connecticut, golf officials at the Travelers Championship on Wednesday treated dozens for heat exhaustion.
"People are coming in dizzy, a little nausea, vomiting, generally poor feeling overall," the AP quoted emergency medical services director John Quinlavin as saying. "We generally have a more mature audience here, and we do see a lot of the elderly having some problems with the heat."
