Offshore flow, partly cloudy skies, and temperatures a few degrees above normal will continue through Monday.
Glorious December sunset from the pier in Cayucos!
Imagery continues to show a steady stream of high clouds through southwest California. The highest possibilities for rainfall will be in San Luis Obispo County Monday night into Christmas morning. Storm totals are expected to be below a quarter inch in most regions. Local amounts greater than a quarter inch are possible along some north facing slopes.
The most significant impact of this low-pressure system will be strong northwest to north winds.
Strong/potentially damaging NW-N winds gusting 40-60 mph possible across portions of SW Calif late Mon night-Christmas Day. Strongest winds expected across the mountains, Antelope Vly, SBA south coast, and Santa Clarita Vly. Potential for downed trees/powerlines. #LAwind #cawx

Monday night and early Christmas morning, wind advisories will likely be needed. Potentially damaging wind gusts up to 60 mph are expected across the Santa Ynez Range and foothills of the Santa Barbara County south coast, resulting in a high wind watch from 8 a.m. Tuesday to 10 p.m. Tuesday. Other portions will likely see wind gusts in the 35 to 5 5mph range on Christmas afternoon.
Snow levels could drop as low as 4000 feet by Christmas morning on the north facing slopes, which could result in a dusting of snow on Interstate 5 near the Grapevine.
A storm system will bring strong, potentially damaging N winds to the area Mon night & Christmas Day, along with mainly light rainfall & snow above 4,000 feet. Mountain roads will be dangerous – icy with blowing snow! #SoCal #CAwx #LAsnow pic.twitter.com/DMjhTFJA4F
