Wider weather episode

The dense fog which prevailed over much of the San Joaquin Valley on January 7 lifted into a stratus deck which expanded toward the valley facing slopes of the Sierra foothills and Kern County Mountains. Northerly flow resulted in the stratus banking up in the Fort Tejon and Tehachapi areas which resulted in dense fog which impacted travel over the Tejon and Tehachapi passes on January 8. Downslope wind gusts impacted the ridge tops and below the passes in Kern County Mountains during the morning hours of January 8 with several locations measuring gusts exceeding 45 mph, and a few low impact indicator sites briefly measuring gusts exceeding 55 mph.
