 This is KNPR News. I'm Dave Becker. For the first time in its history, Las Vegas hit a temperature of 120 degrees yesterday. Dozens of locations across the West tied or set new heat records over the weekend. In addition to Las Vegas, Death Valley recorded readings of 128 degrees both Saturday and Sunday. Redding, California hit 119. Salem, Oregon reached 103. Heat advisories have been extended even into higher elevations, including around Lake Tahoe.
