 This is KNPR News. I'm Dave Becker. Well, it's another day and another extension of the current excessive heat warning. Earlier today, the National Weather Service extended the warning through Friday evening at 11 p.m., saying Las Vegas is expected to see high temperatures throughout the week of 112 to 118 degrees. The warning covers much of our region, including Pahrump, Barstow, the Owens Valley, and, as you might expect, Death Valley.
