As you can see in the video below Saturday still looks like the most promising strong wind day for Southern California. The bulk of North Pacific High’s surface NW winds will be shoved south of the Bay Area by a storm system. So the peak winds will be in the Southern California bight.
This wind will be rushing to a deep low pressure the Great Basin. Unfortunately in this pattern the strongest wind will be just over the beaches. But there is a decent chance the NPH’s surface winds will move close enough to the beaches for some low 20’s. Expect gusty or even UP AND DOWN winds as the strong wind aloft randomly descends to the surface.
