Western U.S. heat wave continues this week after breaking hundreds of records

A historically intense and long-lasting heat wave in the Western United States, which has set hundreds of records from Washington state to Arizona, will continue to scorch the region for several more days. The first signs of even modest relief do not materialize until late this coming weekend.

This past weekend, astonishingly hot weather brought all-time highs of 119 degrees to Redding, Calif., and 120 to Las Vegas.
