A winter Weather report the system began to work its way through the San Francisco bay area over the weekend bringing light rain and cooler temperatures as well as the possibility of small hail and isolated thunderstorms which are expected to affect the region early in the week.
Light precipitation fell over most of the Bay Area on Saturday, National Weather Service meteorologist Roger Gass told SFGATE. Just a tenth of an inch of rain strewn over the inner East Bay, the North Bay coastline and higher areas like Mount Tamalpais and the Santa Cruz Mountains. Parts of Marin County had up to half an inch. Downtown San Francisco saw lots of drizzle but reported no measurable rain and San Mateo, Sunnyvale and Santa Clara only picked up one to two hundredths of an inch.
