Summary
More than 72 million people across the South remain under heat alerts even as a Canadian cold-air system begins breaking up the heat dome and brings modest relief into the weekend.
Over 18 million are still under Extreme Heat Warnings, with Level 4-of-4 HeatRisk persisting through Friday in the Lower Mississippi Valley and along the Southeast coast.
Triple-digit heat indices are still hanging on from the Southern Plains to the Southeast, and Dallas could stay at or above 105 degrees through next Tuesday—its longest such stretch since 1980.
Nearly 50 record highs fell across the South this week, capping the hottest summer on record for 36 cities from Texas through the Carolinas and Florida.
Miami hit 100 degrees for only the second time on record, underscoring a broader danger as NOAA says heat kills more Americans each year than any other extreme weather.
