Summer may be almost over, but it’s not over yet.

The area will be hit by extreme heat on Wednesday, which could lead to heavy storms later in the day.

A heat warning goes into effect at 11 a.m. for New York City and adjacent counties in all directions. Most of New Jersey will be under at least a heat warning, with temperatures in the 90s and high humidity resulting in heat index readings as high as 103 during the hottest part of the day.

An extreme heat warning is in effect from Trenton to Philadelphia, with temperatures reaching 105. Check here for the latest extreme weather warnings in your area.

A red alert was issued for the city of Newark, advising at-risk residents (senior citizens or those with chronic health conditions) to take precautions and to check on everyone’s neighbors who are alone. The city also advised that air quality is expected to be unhealthy for sensitive groups. The same precautions are in place in New York City.

The heat advisory will remain in place until 8pm, after which temperatures should drop below the danger zone. Thursday will be considerably cooler, with temperatures only reaching the 70s.

Storm Team 4’s Latest Prediction

When do storms occur?

Storms should start to pick up in the late afternoon or evening ahead of a cold front. They won’t be widespread, but any storms that do develop could be strong to severe. Central and South Jersey will likely feel the impact first.

The primary threats are damaging straight-line winds and large hail. Wind gusts could exceed 50 mph, strong enough to blow branches off trees and knock down power lines.

Hail produced can be over an inch in diameter. At that size, hail can cause minor property damage, such as cracking a windshield or denting the hood.

Once the storms and associated cold front pass, temperatures and humidity drop significantly, going from highs of nearly 10 degrees above average to highs of nearly 10 degrees below average.

Temperatures will remain moderate for the remainder of the 10-day forecast. There is still a chance of showers and storms on Saturday as the second cold front of the week moves through the region. The rest of Labor Day weekend should be warm and mild (although it certainly won’t be a beautiful weekend for travelers).

Looking ahead, the days are starting to feel more autumnal and next week morning temperatures will drop to around 10 degrees Celsius. Yummy weather!
