A strengthening heat dome over the nation's heartland United States will drive brutal temperatures through Monday, exposing a wide share of the population to high heat.
The most intense dome is anchoring over the Rockies and Plains, while heat advisories continue for portions of southern Colorado and several Midwestern states.
Thunderstorms may fire up in scattered areas but will offer scant relief from the sweltering heat.
Forecasters warn the dome's intensity will hold off cool fronts and sustain record-breaking conditions deep into next week.
Residents are urged to drink plenty of water, limit outdoor exposure during peak hours, and watch out for vulnerable neighbors as the stretch of searing heat spreads over the nation's interior.
