It’s winter somewhere. Accompanying a wave of chilly temperatures in Northern California Monday was the region’s first major snow storm—bringing up to two feet of snow at the highest elevations in the Sierra Nevada. Law enforcement shut down Highway 20 when six inches of snow caused five big rigs to jackknife. Traffic delays aside, the snow is a good sign for California, a state that relies heavily on winter snow accumulation for its water supply. Residents in snowy areas seemed to be enjoying the flurry of attention that accompanied the snow. "It looks like Mother Nature threw us our first snowball,” said resident Rochelle Jenkins.
