A weak low pressure system is slowly moving into central and southern California. There have been a few reports of rain drops along the Central Coast but as expected showers are going to be few and far between with minimal amounts and impacts. Light shower activity should increase in areal coverage later this afternoon and evening but some areas will see little to no rain, particularly in the shadow of the Transverse Range. Breezy conditions are expected in the desert through tonight but below the 45mph threshold for a wind advisory.
Sprinkles or light showers may carry over into Sunday morning, mainly the Central Coast and in the mountains, otherwise still cool Sunday with temperatures in the 60s, 6-12 degrees below normal. A little more sunshine is expected across coast and valley areas south of Pt Conception Sunday but inland areas will take until later in the day to clear.
Much more typical spring southern California weather Mon/Tue with clear skies and temperatures warming back into the 70s by Tuesday.
(Wed-Sat), 25/218 PM.
Still quite a bit of uncertainty mid to late next week as another weak upper level low approaches the area Wednesday. The system is partially cut off from the jet stream so timing is an issue and it's lacking in moisture. Models have been slowing the arrival of this system and it now looks like it will be at least Thursday before it arrives locally. There are some small rain chances in the forecast but will probably need another few days to get a better handle on it.
Following that, weak high pressure will return to the West coast through Saturday for warming temperatures.
