A gripping heat dome over the central and western United States will drive extreme temperatures through Monday, exposing a wide share of the population to high heat.
The most intense dome is forming over the Rockies and Plains, while heat advisories persist for portions of southern Colorado and several Midwestern states.
Thunderstorms may develop in scattered areas but will offer scant 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 drink plenty of water, limit outdoor effort during peak hours, and keep an eye on older relatives as the stretch of searing heat intensifies throughout the nation's midsection.
