A cold weather system will move into southern California late Friday night and Saturday, bringing low snow levels and strong winds. Rain will move into San Luis Obispo and Santa Barbara Counties Friday night and spread into Ventura and Los Angeles Counties late Friday night and Saturday. The system should pass by Saturday night. Snow levels will drop to 3,000 to 3,500 feet by early Saturday. On Saturday, snow accumulations of up to 6 inches are expected above 4,500 feet, and up to 3 inches at 3,000 feet. An inch or two of snow cannot be ruled out for the Antelope Valley foothills as well. Accumulating snow is expected to affect travel along the Grapevine on Interstate 5 on Saturday. In addition to the rain and snow, gusty west to northwest winds will develop with and behind the cold front Saturday. Gusts up to 55 mph are expected Saturday night near I-5. Otherwise, wind gusts up to 45 mph will be possible in the mountains and Antelope Valley. The combination of snow and gusty winds will result in hazardous driving conditions in the mountains with icy, snow-covered roads and poor visibility due to blowing snow, especially impacted will be high-profile vehicles due to the winds. If you are traveling into the mountains late Friday night and Saturday, be prepared for slowing and possible road closures. This also including I-5 over the Grapevine.
