Latest radar imagery depicts scattered light showers over the mountains, with isolated light showers across portions of the Valley. Chances for mountain showers and isolated thunderstorms persist through early this week as a trough pattern prevails across interior northern California. Latest WPC guidance indicates additional precipitation amounts ranging from 0.25-0.50" over the mountains, with up to 0.75" over the Coast Range. Additional light snow accumulations of 1 to 3 inches are expected across northern Sierra passes and the southern Cascades above 5500-6000 feet through Monday evening. Travel impacts should be limited, with slippery roads at times. In addition, locally breezy south to southwest wind gusts up to 15-25 MPH continue today, strongest across the mountains.
