A building heat dome over the nation's heartland United States will drive dangerous temperatures through Monday, exposing a wide share of the population to high heat.
The strongest dome is forming 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 provide minimal relief from the stifling heat.
Forecasters warn the dome's intensity will hold off cool fronts and sustain record-breaking conditions well into next week.
Residents are urged to keep water handy, limit outdoor exposure during peak hours, and keep an eye on older relatives as the stretch of sizzling heat spreads across the central half.
