A tightening heat dome over the mid-section United States will drive dangerous temperatures through Monday, exposing a significant share of the population to high heat.
The most intense dome is anchoring over the Rockies and Plains, while heat advisories stay active for portions of southern Colorado and several Midwestern states.
Thunderstorms may develop in scattered areas but will provide minimal relief from the sweltering heat.
Forecasters warn the dome's intensity will stall cool fronts and push record-breaking conditions well into next week.
Residents are urged to keep water handy, limit outdoor strenuous work during peak hours, and watch out for vulnerable neighbors as the stretch of sweltering heat grows across the central half.
