A strengthening heat dome over the nation's heartland United States will drive dangerous temperatures through Monday, exposing a significant share of the population to high heat.
The deepest dome is taking shape over the Rockies and Plains, while heat advisories remain in effect for portions of southern Colorado and several Midwestern states.
Thunderstorms may pop up in scattered areas but will offer scant relief from the oppressive heat.
Forecasters warn the dome's intensity will hold off cool fronts and sustain record-breaking conditions right through next week.
Residents are urged to stay hydrated, limit outdoor exposure during peak hours, and watch out for vulnerable neighbors as the stretch of sweltering heat intensifies throughout the nation's interior.
