Temperatures are cooling slightly, with much of the coast moving into the 60s. Interior areas and valleys will be in the 70s to low 80s.
California is now under low pressure. Onshore flow is increasing, which is deepening the marine layer. Through the day, fog will clear to the beaches.
The trough axis will move over the region Friday. The marine layer will stay deep and extend into valley areas. Gusty onshore winds will pick up in the evening.
Temperatures will warm slightly again Saturday with the west to northwest winds, particularly in Santa Barbara County, but the marine layer will persist.
Temperatures drop again on Mother's Day to near normal. Early next week, the region will gradually warm up as onshore flow decreases.
