 Las Vegas breaks a heat record. KLAS-TV weather anchor Nate Tannenbaum. Five days in a row at 115 or higher. We're coming up on more than 10 days in a row with afternoon highs at least 110. Peak temperatures also expected today in Los Angeles County, California. And the city of Lancaster has had temperatures over 110 degrees for almost a week. When it gets over 100, it's usually in August, but it's been starting earlier. It's just miserable.
