What happened

The episode as NWS HNX wrote it up.

On the 6th and 7th, a low pressure trough brought some rain and mountain snow to the area, but the main threat was strong and damaging winds in much of Kern County, including the desert and mountain areas. On the 6th, Bakersfield experienced gusty winds up to 35 mph as the cold front passed over the area. Wind gusts reached over 80 mph at some locations in the desert on the 7th. On this day, the winds were strongest during the morning and afternoon hours, when pressure gradients and upper level winds were most favorable. at 1130 AM a roof blew off a house just south of Weldon. A total of 5 semi truck trailers were blown over near Mojave and the intersection of Highways 58 and 14. At Edwards AFB, high winds caused damages to a house, car, and a garage. Also just to the west of Rosamond, several power poles were snapped and toppled due to the high winds.

Winds subsided during the evening hours, but a few locations in the desert saw gusts continuing at 50-70 mph. By the 8th, temperatures remained several degrees cooler before then next ridge of high pressure strengthened over the area.

NOW NEAR 630 AM. YET...WILL BE ON THE LOOKOUT FOR ANY POSSIBLE FOG
DEVELOPMENT THIS MORNING.

AFTER TODAY STORM...MODELS THEN DEVELOP A RIDGE PATTERN OVER THE
