Western Heat Dome Triggers 115°F Record Threat
A powerful high-pressure heat dome from Arizona to Montana is driving dangerous temperatures across the Western United States, according to the National Weather Service. Las Vegas hit 115°F, Phoenix faced highs near 116°F, and El Centro, California, reached a record 118°F, while Great Falls, Montana, set a record at 104°F. Meteorologists warn that overnight lows in the upper 80s to low 90s heighten health risks. Extremely low humidity and dry vegetation have prompted red flag wildfire warnings, and emergency cooling centers in places like Billings have opened to protect vulnerable residents.
