After narrowly avoiding blackouts, California faces another bruising test of its power grid Thursday as a heat wave smothering the state builds, driving temperatures to dangerous levels.  

Nearly all of the state is under an excessive heat warning, with temperatures in Sacramento forecast to hit 105 degrees Fahrenheit (40.5 Celsius). Palm Springs is expected to reach 113 degrees.
