Hail in Glenn County, California

Hail covered the roads and a grain field was flattened by at least penny-size hail. The hills were whitened by hail. In addition, there were 0.57 inches of rain in Artois in one hour. An NWS employee on a storm survey the next day measured hail to 1.25 inches in diameter, with depths of the hail exceeding 6 inches.

A cold winter storm brought 1 to 5 feet of storm total snow accumulation to the higher mountains of the southern Cascades and to the northern Sierra Nevada. Snow levels dropped to near 4000 feet during the latter part of the storm. Gusty winds brought reduced visibilities and broad drifting of snow.

This system also generated thunderstorms in the Central Valley, bringing heavy rain, flash flooding, and other severe effects. Large amounts of hail were reported over Shasta and Glenn Counties, larger than quarter size and more than 6 inches deep in some areas. Flash flooding and slides closed Highway 70 with minor flooding over a number of rural roads. Numerous car accidents from wet roads were reported across the area, as well as trees falling from a combination of wet ground and wind.
