VIDEO: The Northeast and Midwest, including New York City and Boston, are bracing for what could be the hottest stretch of weather in 30 years this week as a sweltering heat dome settles over a large part of the nation.
Over the next six days, 265 million people, or about 82% of the U.S. population, are likely to experience temperatures topping 90 degrees as the official first day of summer arrives on Thursday.
Many cities in the Midwest and the Northeast could experience what the National Weather Services calls rare and long-duration heat with up to five straight days of 95-plus-degree weather with high humidity that will make it feel 100 to 105 degrees.
As of Monday morning, 17 states from Iowa to Maine were under a heat alert.
