NEW YORK — Thick air, pop-up thunderstorms and unforgiving heat is bearing down on the tri-state area, prompting a heat advisory and air quality alert.

The combination of heat and humidity is expected to make New York City and parts of New Jersey feel like it is 95 to 99 degrees for two or more days, or 100 to 104 degrees for any length of time, according to the National Weather Service.

The advisory is in effect for the five boroughs, and in parts of Hudson, Bergen and Essex counties. It is set to remain in effect through 6 p.m. Thursday.

In Nassau and Suffolk counties,  an air quality alert warns of high pollutant levels and advises people limit how much strenuous activity they do outdoors.

Farther southwest, an excessive heat watch has been issued for Trenton and Camden in New Jersey, as well as Philadelphia, warning of feels-like temperatures of 100 and 105 degrees on Thursday.

Temperatures will reach the upper 80s in the city Wednesday, and low 90s Thursday, but the high humidity will make it feel much hotter.

In Peekskill, highs will feel like 100 degrees Thursday; in Kips Bay, closer 107 degrees; and in South Amboy, a whopping 110 degrees.

The high heat and humidity can negatively impact older people, those with pre-existing conditions and people work outdoors, the weather service warns. Family, friends and neighbors are all encouraged to check on these individuals, and everyone is advised to drink plenty of water, use air conditioning and limit time outdoors during extreme heat.

Depending on where the front settles on Friday, an onshore flow will develop, creating cooler conditions and the risk of a few showers. Temperatures, especially across coastal sections, may stay in the 70s through the day — some 20 degrees below days prior.
