A series of storms will bring rain to the region later this afternoon (Central Coast) into at least Wednesday, with chances for additional precipitation existing through Friday. Most likely outcome for rainfall amounts Sunday-Wednesday is 2-4 inches coast/valleys and 4-8 inches foothills and mountains. This is going to be a very dynamic convective system and 1+ inch per hour rain rates are possible. There is a threat for significant mountain snow Monday, and periods of snow from Tuesday night into Wednesday as snow levels will lower to around 3000 feet. $$
