There is a cold front associated with an area of low-pressure NW of the Central Coast roughly 950 miles off the Central Coast as of late Friday. The low tracks to the NE directing a plume of subtropical moisture into northern CA. In northern CA the storm will be significant, producing 1-3" of valley rain the 3-6" in foothill and mountain areas. Locally the storm will not produce much rain. We are simply too far south and the moisture plume is already beginning to draw in dry air, by the time the front pushes over the Central Coast only light to about .30" of rain is likely. These totals will be lowest in the interior valleys and SB Southcoast, some people in these areas may not get any measurable rain.
While some rain could fall after midnight the primary activity will pass from 3a-8a Saturday morning with skies clearing and NW winds picking up by early afternoon. Winds of 15-30mph are possible later Saturday. Sunday also looks breezy to windy before winds turn offshore Monday for a temp bump. This will push temps into the 70s and 80s early next week.
There are two more cold fronts next week, one Tuesday and another Thursday. I don’t think they produce local rain but they will pick up the NW winds from time to time keeping temps in a seasonal range.
