(CNN) – More than 15 million people are under a heat advisory in parts of New York and New Jersey this Thursday and Friday, when temperatures are expected to rise several degrees above normal.

“Heat index values ​​of up to 37.2 ° C are expected today and up to 39.4 ° C on Friday,” said the Office of the National Weather Service in New York.

The heat warning begins at 11 a.m. this Thursday and will continue until 8 p.m. Friday.

The New York Weather Service also said Friday will be the hottest of the two days.

Summer returns with heat and humidity building across the Tri-State to end the workweek. Heat Advisory is in effect from 11 AM this morning through Friday evening. With the humidity, it’ll feel like the mid-to-upper 90s at times. Here’s today’s maximum heat index values: — NWS New York NY (@NWSNewYorkNY) July 15, 2021

“Urban areas could register heat indices reaching 37.2 ° C -39.4 ° C in the afternoon. Surrounding areas, such as the lower Hudson Valley and southern Connecticut, will likely experience heat rates of between 33.8 ° C and 37.2 ° C during the day, ”the weather service said.

Newark and New York City, both with heat warnings on Thursday, are also in the top three worst cities for urban heat.

These cities have the worst “heat islands,” and temperatures can rise between 5.5 and 11 degrees in a few blocks.

Although other areas of the Northeast do not have heat warnings, that does not mean that they will not feel the heat and humidity.

The Philadelphia Weather Service said highs will exceed seasonal averages by a few degrees, combined with very high humidity levels. As a result, the heat index values ​​will probably reach 32.2 ° C, but will not reach 37.7 ° C.

High humidity levels will also help fuel some afternoon thunderstorms in the area, although severe storms are not expected.

July 15. Right smack in the middle of meteorological summer! While not nearly as oppressive as it has been at times this summer, it’ll still be a relatively hot & humid day. Highs will be a few degrees above seasonal averages. — NWS Mount Holly (@NWS_MountHolly) July 15, 2021

As if the heat wasn’t enough, there are also air quality alerts in five northeastern states due to high concentrations of air pollution.

Why is it getting hotter in the United States? This experts say

“The New Jersey Department of Environmental Protection issued a code orange air quality alert on Thursday,” the weather service office in Philadelphia said in its alert statement. “A code orange air quality alert means that air pollution concentrations within the region can become unhealthy for sensitive groups.”

Sensitive groups include the young, the elderly, or people suffering from asthma, heart disease, or other lung diseases.

“The effects of air pollution can be minimized by avoiding strenuous activities or exercise outdoors.”
