The wider storm
Low pressure formed off the coast of California and tapped into tropical moisture which lead to widespread Valley rain, mountain snow, and eventually even thunderstorm development over interior northern California. Valley rain amounts generally ranged from 0.25 to 1.0 inch of rain while foothill locations received 1.0 to 4.0 inches of rain. High elevation mountain snow was bountiful too with most sites reporting 1 to 2 feet of snow. The next day, behind the main front, widespread showers and thunderstorms developed on Nov 19.
Began near Valley Spgs (38.1800, -120.8300).
