A strengthening heat dome over the nation's heartland United States will drive brutal temperatures through Monday, exposing a substantial share of the population to high heat.
The deepest dome is taking shape over the Rockies and Plains, while heat advisories persist for portions of southern Colorado and several Midwestern states.
Thunderstorms may pop up in scattered areas but will provide minimal 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 keep water handy, limit outdoor exposure during peak hours, and check on neighbors as the stretch of sweltering heat spreads across the central half.
