Heat wave and high humidity will blast much of the eastern US this week, meteorologists say
The first widespread heat wave of summer will bring heat indexes up to 115 degrees, forecasters said.
- On Sunday, June 28, 2026, the National Weather Service reported that over 130 million Americans across southern and Great Plains states face moderate to severe heat risk conditions, with dangerous heat expanding across the eastern two-thirds of the U.S. this week.
- AccuWeather meteorologist Tyler Roys explained that a high-pressure system acts like a "rock," creating a "heat dome" that traps hot air and forces storms to detour, limiting rainfall across the East.
- High humidity will push heat indices between 100 and 110 degrees, with some areas reaching 115 degrees, placing millions in National Weather Service "major" or "extreme" risk levels this week.
- Major cities hosting World Cup matches and July Fourth celebrations, including New York and Chicago, face their highest temperatures of the year, complicating outdoor activities for spectators and residents.
- Nightly lows in the 70s or high 80s will prevent bodies from recovering, creating dangerous conditions for residents without air conditioning, especially on the Eastern Seaboard where temperatures may not dip below 80 degrees.
