A gripping heat dome over the nation's heartland United States will drive oppressive temperatures through Monday, exposing a large share of the population to high heat.
The heaviest dome is taking shape over the Rockies and Plains, while heat advisories persist for portions of southern Colorado and several Midwestern states.
Thunderstorms may develop in scattered areas but will do little relief from the oppressive heat.
Forecasters warn the dome's intensity will slow cool fronts and carry record-breaking conditions right through next week.
Residents are urged to drink plenty of water, limit outdoor effort during peak hours, and check on neighbors as the stretch of searing heat grows throughout the country's interior.
