What happened

The episode as NWS STO wrote it up.

A secondary wave of precipitation brought additional rain, wind and light mountain snow from November 16th through November 17th. This led to additional flooding impacts in the Valley and foothills. 1 to 3 inches of rain were observed over this two day timeframe across most of the area, except in Shasta County where 2 to 5 inches were observed. There were also snow measurements of around 3 to 8 inches in the mountains generally above 6500 feet with this round. Southerly wind gusts of 25 to 45 mph were observed as well, which brought down a few trees and branches.
