What happened

The episode as NWS HNX wrote it up.

An upper trough deepened over the Pacific Northwest on October 7 then dropped into the Great Basin on October 8 and 9. This resulted in an increased offshore pressure gradients which produced moderate gusty northeast winds across the Kern County Deserts as well as gusty downslope winds in the south San Joaquin Valley and below the Tehachapi and Grapevine passes in the Kern County Mountains during the morning and early afternoon hours on October 9. Wind advisories were issued well in advance of this event as holiday travel on State Route 58 and Interstate 5 were impacted during the Columbus Day Holiday, and there were several reports of gusts exceeding 35 mph in the impacted areas.
