Death Valley, Calif., could soon see its hottest temperature to date.

The 3,000-square-mile area in the northern Mojave Desert recorded its second-highest temperature July 12 at 128 degrees Fahrenheit, in a peak following a string of four days that saw heat readings of 120 degrees, 124 degrees, 128 degrees and 124 degrees.

While Death Valley knocks on the door of a heat record, other U.S. states are registering new highs, too. Borger, Texas, recently set a one all-time record set of 116 degrees. Springs, California, hit a daily record of 121 degrees. And Tucson, Arizona hit 113 degrees.
