A long-lasting and expansive heat wave is set to grip the Midwest and Northeast with record-breaking high temperatures through next week, ushering in the start of summer with this year’s most significant heat event yet. Nearly 200 high-temperature records could be tied or broken this week as a massive heat dome parks over part of the East and may last into early next week. Some areas could endure the longest heat wave they’ve seen in decades, the National Weather Service’s Weather Prediction Center said.
Tens of millions of people who aren’t used to heat this intense will be sweating in temperatures well into the 90s this week. The heat arrived in the South and Midwest as many families celebrated Father’s Day outdoors on Sunday, prompting caution from the weather service to stay cool amid 90-degree high temperatures in some areas.
