"Dangerously hot" conditions may peak across portions of interior California, the Great Basin, the Southwest and South Texas on Friday. Still, extreme heat is likely to "plod" into next week, the National Weather Service warned.
The big picture: Heat alerts remain in effect for about 25 million people Friday, after widespread temperature records were tied or broken in California, Nevada and Arizona Thursday — including in Phoenix, where 11 people who were waiting in line to enter a Trump rally were hospitalized due to heat-related illnesses.
