After a comfortable start to the week, a burst of hot weather is headed our way as a piece of the central U.S. heat dome drifts eastward. Cities like New York City, Philadelphia, and even Detroit could experience temperatures soaring into the 90s, combined with oppressive tropical humidity. The nights won't offer much relief either, making it crucial to take precautions against the heat.

The following conditions are expected during the heat surge.

Expect daytime highs in the low to mid-90s (Fahrenheit) across many areas of the Northeast. With the humidity factored in, the heat index could reach dangerous levels, making it feel even hotter.

The air will be thick with moisture, adding to the discomfort. Be prepared for sticky and uncomfortable conditions.

Temperatures will remain elevated overnight, making it difficult for homes to cool down. Consider using fans or air conditioning to stay comfortable.

The heat surge is expected to be brief, lasting from late in the work week into Saturday.

Relief is on the horizon! A strong backdoor cold front will sweep through the region on Sunday, bringing a welcome cooldown and a return to more seasonable temperatures.

The following are recommended safety tips during extreme heat.

Drink plenty of water throughout the day, even if you don't feel thirsty. Avoid sugary drinks and alcohol, which can dehydrate you.

Spend time in air-conditioned places, such as shopping malls, libraries, or community centers. If you don't have air conditioning at home, consider visiting a cooling center.

Avoid strenuous activities during the hottest part of the day. If you must be outdoors, take frequent breaks in the shade.

Wear loose-fitting, light-colored clothing to help your body stay cool.

Wear sunscreen, a hat, and sunglasses when outdoors.

Check on elderly neighbors, friends, and relatives who may be more vulnerable to the heat.

Never leave children or pets unattended in a car, even for a few minutes. Temperatures inside a car can quickly rise to dangerous levels.

A "heat dome" is a large area of high pressure that traps warm air underneath it. The air sinks, compresses, and heats up, leading to prolonged periods of hot weather. In this case, a portion of the heat dome that has been baking the central U.S. will shift eastward, bringing the heat to the Northeast.

While the late-week heat will be intense, it's expected to be short-lived. The approaching cold front will bring a significant drop in temperatures and a return to more typical summer conditions. Stay tuned to your local weather forecast for the latest updates and be sure to take precautions to stay safe during the heat surge!
