From my SLO Weatherperson, “Asthe ridge remains entrenched, subtropical moisture will be  transported northward over most of California on Sunday into  Tuesday with increasing mid to high-level clouds and a potential for rain showers and thunderstorms. It will feel muggy in the inland areas, however, increasing northwesterly winds on Sunday  afternoon into Tuesday will keep the beaches and coastal valleys cooler. 

 The ridge will move off to the northwest late next week for gradually cooler temperatures over the 4th of July weekend.
