Dangerous and potentially record-breaking heat is forecast to peak through July 14, 2026, across the western and north-central United States. Billings, Montana, already shattered its all-time temperature record on July 12, while Salt Lake City, Utah, tied for its second-highest reading ever, just short of its own all-time mark. More locations could still challenge records as the heat continues into Tuesday. Very warm nights are adding to the danger by increasing heat stress over several consecutive days.
