A tiny desert community in Southern California has tied the highest March temperature ever recorded in the U.S. The 108 degree day in North Shore, California, came amid a record-breaking winter heat wave in the Southwest that will stretch into the weekend and could produce even higher temperatures. The record it now shares with Rio Grande City, Texas, could be broken in a number of cities and towns by week’s end. Triple-digit temperatures also came earlier than ever before in Phoenix when the Arizona capital hit 101 degrees Wednesday, according to the National Weather Service. Phoenix's previous record was set almost 40 years ago, in 1988.
