Northern California Gets Light Rain and Snow

A weak storm system moved through Northern California on Tuesday and a stronger system was expected in the drought-stricken state during the weekend, the National Weather Service said.

Meteorologists reported that Sierra Nevada elevations above 6,000 feet (1,829 meters) received 1-3 inches (2.5-7.6 centimeters) of snow, and chains were required on Interstate 80 through the morning.

The UC Berkeley Central Sierra Snow Lab said rain unexpectedly turned to snow.
