Wider weather episode

A strong upper trough moved through California on December 14 arriving during the late morning hours. The main impact that this system has it that a mid level jet stream ahead of it produced a period of strong wind gusts which mainly affected the West Side Hills and the Sierra Foothills in Mariposa and Madera Counties during the late morning and early afternoon of December 14. Several stations in these areas reported wind gusts exceeding 60 mph with some stations picking up gusts in excess of 75 mph. Power outages were reported in several communities in the Sierra Nevada and adjacent foothills due to the strong wind gusts knocking down trees and power lines. In addition, this system also produced moderate precipitation in the Sierra Nevada and adjacent foothills from Fresno County northward with several stations picking up between a quarter and a half inch of liquid precipitation and several SNOTEL stations above 6000 feet picking up an estimated 3 to 8 inches of new snowfall. Further south in the Sierra Nevada, precipitation was lighter with most locations receiving a tenth to a quarter of an inch of liquid precipitation. Rain shadowing limited most of the San Joaquin Valley to a tenth of an inch or less of rainfall. The trough moved to the east of the area by the evening of December 14.
