Of course, California has always been in a zone of extreme variance of precipitation. This goes with extreme seasonality of precipitation, and one can't have much more seasonality than California. In a normal year, San Francisco is about as rainy as Atlanta in the winter and about as dry as the Namib Desert in the summer. There have been years in the recent drought when Phoenix had more rainfall than San Francisco.
There is much ambiguity of whether rainfall patterns will change, and how, under warmer conditions in the middle latitudes. Warmer oceans in the subtropics could mean that the "Pineapple Express" will prevail more in the winter in California, bringing warmer, moister, and truly tropical air masses on occasion to California during the winter. Such air masses will be hit by maritime polar air masses that originated in Siberia and crossed the Pacific, having gone from extremely cold to simply cool over the Pacific, setting up huge storms. But that is a comparative positive. The Central Valley and the desert regions of southeastern California will get much more rain.
