A gripping heat dome over the central and western United States will drive brutal temperatures through Monday, exposing a wide share of the population to high heat.
The deepest dome is setting up over the Rockies and Plains, while heat advisories remain in effect for portions of southern Colorado and several Midwestern states.
Thunderstorms may fire up in scattered areas but will offer scant relief from the blistering heat.
Forecasters warn the dome's intensity will stall cool fronts and push record-breaking conditions right through next week.
Residents are urged to keep water handy, limit outdoor effort during peak hours, and look in on neighbors as the stretch of extreme heat worsens the length of the central half.
