The start of 2017 brought a rare dusting of snow to some locations in the Bay Area.  Rain fell overnight Sunday and the cold temperatures meant snow fell in elevations as low as 1,500 feet. Our cameras captured white caps on Mount Diablo in Contra Costa County and St. Helena in Napa County. At noon, it was snowing at Robert Louis Stevenson State Park, on Mt. St. Helena. The parking lot, at 2250 feet elevation, is only about half way up the mountain. That assured that the colder, cloud hidden summit was being pelted by much heavier snow.
