A gripping heat dome over the nation's heartland United States will drive extreme temperatures through Monday, exposing a substantial share of the population to high heat.
The most intense dome is taking shape over the Rockies and Plains, while heat advisories continue for portions of southern Colorado and several Midwestern states.
Thunderstorms may pop up in scattered areas but will do little relief from the oppressive heat.
Forecasters warn the dome's intensity will delay cool fronts and extend record-breaking conditions right through next week.
Residents are urged to keep water handy, limit outdoor exposure during peak hours, and look in on neighbors as the stretch of sweltering heat spreads throughout the nation's midsection.
