A gripping heat dome over the central and western United States will drive dangerous temperatures through Monday, exposing a large share of the population to high heat.
The strongest dome is forming 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 provide minimal relief from the stifling 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 effort during peak hours, and check on neighbors as the stretch of searing heat spreads across the central half.
