'Extremely dangerous,' record-breaking heat wave to hit Fourth of July holiday weekend
A heat wave that's set to break daily temperature records across western and southern states through the weekend has been called "extremely dangerous."
An "extremely dangerous" heat wave is set to break daily temperature records across western and southern states through the holiday weekend, the National Weather Service warned.
The extreme heat comes as 28,000 were forced to evacuate their homes because of a raging wildfire in Northern California. The Thompson Fire in Oroville, about 65 miles north of Sacramento, had grown to 3,568 acres and was only 7% contained on Wednesday night.
California, southern Nevada and Arizona could see triple-digit temperatures on Thursday, with widespread excessive heat warnings, and it will be pushing the 100 degree mark in Tennessee, Arkansas and Louisiana.
The heat index, a measure of how hot it feels that takes into account humidity, could reach the 110s in the lower Mississippi Valley.
In total, more than 100 million people will spend Thursday under heat alerts.
