A strengthening heat dome over the interior United States will drive brutal temperatures through Monday, exposing a large share of the population to high heat.
The strongest dome is anchoring 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 sweltering heat.
Forecasters warn the dome's intensity will delay cool fronts and extend record-breaking conditions through next week.
Residents are urged to drink plenty of water, limit outdoor strenuous work during peak hours, and keep an eye on older relatives as the stretch of sweltering heat worsens the length of the central half.
