 Record-breaking heat is hitting the western U.S., and it's going to continue this week. More from Mark Mayfield. The National Weather Service says dozens of daily record temperatures will be tied or broken across the West Coast as temperatures hit the 110s. Redding, California saw the temperature hit 119, with Phoenix setting a record for the warmest low temperature at 92 degrees. Las Vegas broke its record high on Sunday, hitting 118. I'm Michael Kastner.
