Extreme heat will continue across much of the southern Plains to New England, with more than 150 million people under heat alerts.
Record high temperatures are likely on Tuesday across the Northeast and Florida, where temperatures could climb to the low-100s. Hartford, Connecticut; Newark, New Jersey; Tampa and Orlando in Florida; and Philadelphia are some cities that could see record highs.
Air Quality alerts have also been issued from Rhode Island to Delaware.
“Be careful. Today is an air quality alert day meaning the air is unhealthy for sensitive groups,” the New York City Department of Citywide Administrative Services said in a post Tuesday on X.
By Thursday, the heat will break for the Midwest, Great Lakes and Northeast. In the South, extreme temperatures are expected through the end of the week.
Elsewhere in the country, severe storms have been impacting much of the Plains. On Monday, there were over 200 storm reports and 16 wind reports of at least 75 mph across the Dakotas and Iowa. Four million people are at risk of severe storms on Tuesday across the northern and central Plains.
The storm systems are expected to carry damaging winds, hail and isolated tornadoes. The Central Plains and New Mexico are under a flood risk due to the storms producing rainfall rates of up to 2 inches an hour.
On Thursday, the mid-Atlantic and Northeast could be at risk for urban flash flooding due to thunderstorms.
