Recent storms have dropped more than an inch of rain on San Francisco and blanketed the Sierra with snow, but water levels and snowpack around the state are still lagging far below normal. “It was a few drops in the bucket at least,” Scott Rowe, a meteorologist with the National Weather Service in Monterey, said Saturday. In San Francisco, slightly more than 1.2 inches of rain have fallen since Wednesday, with almost 1.4 inches at San Francisco International Airport. Numbers were similar in the East Bay and South Bay: Oakland got 1.13 inches and San Jose Airport just over an inch.
