November 27 ?Çô December 1: On Monday and Tuesday we can expect cold morning and evening temperatures and sunny afternoons. Late Tuesday we will begin to feel the effects of a low-pressure system moving in from northern California and centering over the Bay Area. Tuesday evening expect clouds and drizzle, building toward wetting rains lasting through early Thursday. Rain totals in the mountains will be 0.5 to 0.75 inches, at the coast 0.25 to 0.5 inches and less than 0.25 inches in the Salinas Valley and San Benito Co. On Friday drizzly conditions are likely. Rain brings GOOD AQI for ozone, PM2.5 (smoke) and PM10 (dust), with the possible exception of MODERATE PM2.5 in the San Lorenzo Valley Monday night/early morning from woodsmoke.
