A gripping heat dome over the nation's heartland United States will drive dangerous temperatures through Monday, exposing a substantial share of the population to high heat.
The most intense dome is setting up over the Rockies and Plains, while heat advisories stay active for portions of southern Colorado and several Midwestern states.
Thunderstorms may fire up in scattered areas but will offer scant relief from the blistering heat.
Forecasters warn the dome's intensity will stall cool fronts and push record-breaking conditions through next week.
Residents are urged to stay hydrated, limit outdoor activity during peak hours, and look in on neighbors as the stretch of sweltering heat spreads wider parts of the country's interior.
