Key Facts
An expanding heat wave hitting the Southwest and Rockies will shift by the weekend to produce “the most oppressive heat of the season to date” from the Midwest to the Northeast this weekend and next week, according to a Thursday statement from the NWS.
Widespread maximum temperatures will likely be tied or broken across the Upper/Middle Mississippi Valley to the Northeast/Mid-Atlantic over the next several days, the NWS said in a Saturday update.
Major and/or extreme heat risks will spread further into the Midwest and East Coast come Sunday, “where anyone without effective cooling and/or adequate hydration will be affected,” the NWS added.
By Saturday: The heat wave will begin in Minneapolis, Kansas City, Mo., Des Moines, Iowa, Memphis, Tenn., St. Louis, Milwaukee, Chicago, Indianapolis and Detroit.
By Sunday: The heat wave should reach Cleveland, Cincinnati, Pittsburgh, Buffalo, N.Y., Nashville, Tenn., Atlanta, Charlotte, N.C., Richmond, Va., Washington, D.C., Philadelphia, New York and Albany, N.Y.
By Monday: The heat wave will hit Boston, Hartford, Conn., and Concord, Mass.
The NWS reported sunny skies, light winds and little overnight cooling will contribute to the heat wave and “significantly increase the danger” of extreme heat, the number one cause of weather-related deaths.
Although the hottest temperatures are expected during the weekend, there is a moderate risk extreme heat will persist into later next week for parts of the Ohio Valley, Mid-Atlantic states and the Carolinas.

Will 2025 Top 2024—the Hottest On Record—as Climate Change Heats Up Planet?
2024 was the hottest year on record, with the average land and ocean surface temperatures reaching 2.32 degrees above the 20th-century average, according to NOAA. The World Meteorological Organization said in an outlook there is an 80% chance that at least one year between 2025 and 2029 will be warmer than 2024 as the planet continues to warm.
Key Background
The National Oceanic and Atmospheric Administration reported an above-average temperature outlook for most of the U.S. in June. The Mid-Atlantic has a 40% to 50% chance to experience above average temperatures, while states in the northeast have a 50% to 60% chance of above normal temperatures, according to NOAA’s outlook. Extreme heat and humidity is a leading weather-related killer in the U.S., killing hundreds every year, according to the NWS, which notes the elderly, small children and people on medication are most exposed to heat related stresses. People living in areas with high heat are encouraged to reduce outdoor activities, drink water and spend time indoors.
