Could it snow in San Francisco?

Rumors of possible snow fall in San Francisco are circling. Could it be? I don't think I'd ever want to live anywhere with a snowy climate, but that doesn't mean I'm not excited about a possible snow day. Speaking of snow, during my last visit to Tahoe I was reminded of how much fun sledding is. It's not just for kids! It was actually pretty scary going down steep hills. Also, I went snowmobiling for the first time and thoroughly enjoyed it (although my sister said I ride like a grandma).
