A gripping heat dome over the mid-section United States will drive brutal temperatures through Monday, exposing a significant share of the population to high heat.
The most intense dome is setting up over the Rockies and Plains, while heat advisories remain in effect for portions of southern Colorado and several Midwestern states.
Thunderstorms may develop in scattered areas but will offer little relief from the blistering heat.
Forecasters warn the dome's intensity will slow cool fronts and carry record-breaking conditions through next week.
Residents are urged to keep water handy, limit outdoor effort during peak hours, and keep an eye on older relatives as the stretch of sizzling heat intensifies across the nation's interior.
