Rugged peaks of the Sierra Nevada received a dusting of snow from an autumn storm that brought Yosemite Falls back to life, but it’s not time for sweaters and hot chocolate everywhere in California. Santa Ana winds typical of fall in Southern California are expected to bring a summerlike heat wave and high fire danger for the next several days from coastal counties northwest of Los Angeles down to the Mexico border. Temperatures in the hottest areas were predicted to soar into the 90s to around 100 degrees Wednesday through Friday.
