It’ll be a stormy Monday — and Tuesday, Wednesday and Thursday.

Major thunderstorms like those that battered New York on Sunday night are expected to hit the Big Apple just in time for the commute home Monday — then linger, threatening downpours for most of the rest of the week.

Adding to the potential misery, the area is also under a heat advisory, with intense humidity forcing the heat index dangerously close to 100 degrees for much of the next few days, according to forecasters.

“With this heat and humidity, it doesn’t take much to kick off some pretty strong thunderstorms,” said Dave Dombek, a senior meteorologist for AccuWeather.

“Not everyone will get hammered, but it will be unsettled throughout the week, with storms possible almost every day.”

The most intense heat should break by Wednesday before dropping into the 70s by Friday, which could see showers but will probably mark the end of the week’s thunderstorms, Dombek said.

“The good news is the weekend looks like it will be pretty nice,” he added.

Sunday’s severe storm brought hail and reports of wind damage. LaGuardia had 159 flights canceled and 328 flights delayed — with another 181 flights canceled and 363 delayed at Newark Liberty airport, according to AccuWeather.

The storm damaged trees and downed power lines across swaths of Pennsylvania and New York, and at least 11 people, including seven children, were injured in Pennsylvania after two trees came crashing down amid the tempest, according to the weather site.
