A strengthening heat dome over the interior United States will drive extreme temperatures through Monday, exposing a wide share of the population to high heat.
The heaviest 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 spark 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 deep into next week.
Residents are urged to drink water often, limit outdoor activity during peak hours, and check on neighbors as the stretch of sizzling heat settles in over the country's interior.
