Even though a cold front slashed across the area Sunday there is still a larger upper level low off the coast near Monterey which has to still cross over the area. This is a cold upper low and is unstable so not only will it likely bring more showers but also a chance of thunderstorms to the area into thru Wednesday at least (and possibly Thursday).
Here is a look at some of the rainfall since the system began:
Snow levels are dropping in the wake of the cold front, and could be down to 4000-4500 feet by late tonight.
The low tracks into the CA/Mexico border by Wednesday but models are showing wrap around rainfall (coming from the east to the west). Depending how quickly it slides east the showers could end Wednesday or Thursday, that's where models differ slightly. Regardless it'll be on the cool side until it departs. Additional rainfall amounts will vary greatly on the Central Coast with some seeing no more rain and on the high side .50-1" (dependants on thunderstorm placement).
Friday looks like we'll definitely be clear of this system.
Warming a little Friday and Saturday but Sunday a fast moving but dry system slings across the state and NW winds should pull temps down but early next week could warm. That said some models are suggesting some return of rain is possible late next week
