More than 185 million Americans from South Dakota to Florida and up the East Coast to Boston are facing extreme heat warnings this week. Heat index values — which combine temperature and humidity — are expected to reach between 108 and 116 degrees across many regions.
Southeast Faces Most Intense Conditions
The most dangerous heat is forecast for the Southeast, where heat indices could soar up to 120 degrees in parts of Mississippi and Louisiana. The Carolinas through Florida may experience “feels-like” temperatures between 105 and 115 degrees.
Midwest and Northeast Also Under Alert
Sweltering temperatures are also impacting the Midwest, with weekend heat indices ranging from 97 to 111 degrees in cities like Lincoln and Minneapolis. The Northeast, including Philadelphia, New York City, and Boston, is expected to see heat indices between the mid-90s and 104 through Monday.
Wildfire Smoke Adds to Hazards
Air quality in parts of New York, New Jersey, and Connecticut remains poor due to smoke from Canadian wildfires. Hazy skies and another plume of smoke could affect the I-95 corridor by Tuesday afternoon.
No Relief Day or Night
High humidity and persistent tropical moisture are expected to keep “feels-like” temperatures between 105 and 115 degrees through Wednesday, especially in cities like St. Louis, Memphis, Charlotte, Savannah, Tampa, and Jackson. Nighttime temperatures are only expected to drop into the 70s, offering little overnight relief.
Record-Breaking Heat
Tampa hit 100 degrees on Sunday, breaking a 130-year-old record. Much of the Southeast, including Atlanta, Charlotte, Jacksonville, and Tallahassee, will remain under a maximum-level extreme heat risk through midweek.
Health officials remind the public that nearly 2,000 Americans die annually from extreme heat and urge caution during this dangerous heat wave.
