NEW YORK (WPIX) – A heat wave is expected to blanket much of the U.S. this week, trapping some in a "heat dome." And yes, it's sweltering.

The National Weather Service warned Sunday that record-breaking heat was forecasted from the Midwest and Great Lakes to the Northeast through the week and into next week.

"The duration of this heat wave is notable and potentially the longest experienced in decades for some locations," the NWS said in a tweet.

Hot and humid weather is in the forecast for many, even prompting air quality alerts in parts of Illinois, Michigan, New York, New Jersey, and Connecticut. Heat index values in New York City alone could hit 100 degrees........
