A quick-moving system will bring some light rain and snow to the region late tonight and Thursday morning. Most liquid precipitation will be less than 0.10 inches in the valley and less than 0.30 inches in the mountains. Expect less than 2 inches over higher elevations, the heaviest snowfall is expected in the northern mountains of Shasta county, with only a dusting down to 2500 to 3000 feet. Breezy northerly winds will develop behind the weather system Thursday night into Friday night.
The weather service also provides a word to the wise: Dry Decembers don't make droughts. In Red Bluff, for instance, there was no rain in December 1989, yet the city finished that water year with 22.02 inches, or 99 percent of normal.
