Another in a series of upper level low pressure systems will sling thru the Central Coast later Thursday into the weekend.  A surface front will move over the coast on Friday morning for some rain.  I think most locations see less than .10" of rain however up to .25" could fall along the northern coast of SLO county.  The SB Southcoast and deep interior valleys may get no rain at all with the front.  This is not the kind of rain that will impact the drought however it does keep temps down and might impact you decision on when to wash your car.

Prior to all that: Wednesday we are in an interesting gap in a highly amplified jet pattern.  I think skies will be partly cloudy and temps on the mild side, similar to today.

After the Friday morning rain: the low kicks out slowly.  High pressure will build in.  At the coast the NW winds will roar in the afternoons of the holiday weekend.  Temps will warm a little into the lower 70s at the coastal valleys but beaches will be in the 60s with clearing skies but the winds up to 30mph will keep temps down.  Inland however will warm into the 80s.  Monday should be in the upper 80s inland.
