An upper-level low is digging into the Pacific NW tonight, it'll keep dropping south along the Sierra into Sunday. The upper low spins Sunday and Monday near Southern California before kicking out by Tuesday.
For most of the area all this system will do is increase the NW winds and cool temps on Sunday, however there is a chance for sprinkles or a few light rain showers on Sunday into Monday in Santa Barbara County.
High pressure will build over California Tuesday into Wednesday. This will produce offshore winds during night and morning hours before shifting out of the northwest during the afternoon. Weather looks quiet most of next week. I think later next week we'll even see some night and morning low clouds near the coast, more of a weather element of spring but not surprising since the pattern looks spring-like.
A few of the models are more optimistic about rain mid-month but no model is showing anything that heavy at this point. Rain shortages are growing.
