An upper-level low-pressure system is moving over the Central Coast currently and will finish moving through later Wednesday.
Some scattered rain showers have developed in San Luis Obispo and Santa Barbara counties, mostly inland/east and at higher elevations, though some rain has moved through southern Santa Barbara County. This activity will continue until sunset, then diminishes with some isolated activity possible Wednesday afternoon but less likely than Tuesday. Total rainfall amounts will be less than a tenth of an inch for most, but where thunderstorms form, amounts could be locally higher.
Wednesday, the coastal temperatures look to be in the 60s for most, while inland locations reach the low 70s. Thursday looks warmer with inland areas getting into the lower 80s, while coastal locations return to the 70s away from the beaches.
High pressure returns Thursday through Sunday. Inland areas will rocket into the upper 80s but coastal valleys will hit the mid-70s. Night and morning low clouds and fog along the beaches will keep the temperatures in the 60s along the coastline.
Not much activity is anticipated in model runs after this departing system with generally mild weather in the outlook.
