Computer forecasts have been fairly consistent with this scenario and have both systems merging and bringing rain to Southern California Tuesday night. Periods of rain and isolated downpours/thunderstorms will be possible through Wednesday. 0.5" to 1.0" of rainfall is possible. I've posted projected rain totals below. You can see that the Central Coast will get the lion's share of the rainfall.
This system is warm-cored, so snow levels will remain high. I'm not expecting any significant snow in local mountains.
I'll bring more updates as the system approaches. I'm also watching for another rain chance possibly arriving next weekend.
