Hot and humid Wednesday in NYC, but it won't last long, forecasters say

New York’s hot sweaty summer isn’t giving way to September without a fight: Meteorologists say today will bring high temps and humidity – but not for long.

“It looks like a kind of a one-day heat event here,” said meteorologist David Wally from the National Weather Service. “We have a cold front coming through this afternoon and some much cooler air arriving later tonight into Thursday.”

The NWS has issued a heat advisory for the city and surrounding areas from 11 a.m. through 8 p.m., with highs expected to reach the mid-90s and heat index values — what it will feel like —  to soar up over 100 degrees, once humidity is factored in.

Trenton and Philadelphia are under an excessive heat warning , indicating temps there will be even higher.

While skies are supposed to be sunny for most of the day, there’s a 30 percent chance of thunderstorms after 2 p.m., which could help cool things down.

Thursday will feel like a completely different season, with temperatures barely reaching the high 70s, Wally said.

“After this, we should get back down to more seasonable, if not below-normal weather through the upcoming weekend into early next week,” he said.

Fans at the U.S. Open Wednesday will definitely be feeling the burn as athletes play their second rounds. Defending champion Coco Gauff is scheduled to face Germany’s Tatjana Maria at Arthur Ashe Stadium at around 7 p.m.

For those looking to cool off at one of the city’s beaches , waves should be about 3 to 4 feet high, and there will be a moderate breeze. City cooling centers likely won't be activated sine the heat isn't expected to last.
