High Wind in South End of the Upper Sierra, California

The Walker Pass RAWS measured a peak wind gust of 71 mph.

Interaction between a strong upper low pressure system dropping southward to the east of the Sierra Nevada and an offshore ridge produced a strong offshore gradient resulting in a period of strong wind gusts over the Sierra Nevada and the Kern County Deserts between the morning of January 7 and the morning of January 8. Several stations in these areas measured wind gusts above 50 mph during this time frame. The winds diminished by late morning on January 8 as the low dropped further southward into Mexico and gradients relaxed.
