New York’s hot, sweaty summer isn’t making way for September without a fight: meteorologists are predicting high temperatures and high humidity today, but not for long.

“It’s looking like a one-day heat wave,” said National Weather Service meteorologist David Wally. “We have a cold front this afternoon and then later tonight, Thursday, much cooler air coming in.”

The NWS has issued a heat warning for the city and surrounding areas from 11 a.m. to 8 p.m., with highs expected to reach 98 degrees and feelings of over 100 degrees, when humidity is factored in.

An extreme heat warning is in effect for Trenton and Philadelphia, meaning temperatures there could be even higher.

Although it is expected to remain sunny all day, there is a 30 percent chance of thunderstorms after 2 p.m. This could cause cooling.

Thursday will feel like a completely different season, with temperatures barely rising above 21 degrees, Wally said.

“Then we should return to more seasonal, or even below normal weather, over the coming weekend into early next week,” he said.

Fans at the US Open on Wednesday will certainly feel the burning pain as athletes play their second round. Defending champion Coco Gauff is scheduled to face Germany’s Tatjana Maria at Arthur Ashe Stadium around 7 p.m.

Today, cooling centers have opened in the city. Here’s where to find one.

If you cool off on one of the city’s beaches, you can expect waves of about 90 to 120 cm high and a moderate breeze.

This story has been updated to reflect that the cooling centers are open today.
