Record Heat Dome Targets the East Through the Fourth of July Weekend

Forecasters warn a dangerous heat dome will push the eastern U.S. into record-breaking heat through the Fourth of July weekend, with highs mostly in the mid‑90s to low‑100s and heat indices of 100–115°F in places. Nearly 200 million Americans are under heat advisories as several all-time records are expected to be challenged on the East Coast. The West remains cooler thanks to a persistent trough, while fire danger rises in parts of Utah, Colorado and New Mexico. Stay hydrated, seek air conditioning, limit outdoor exposure, and check on vulnerable neighbors.
