...Winter Weather Advisory in effect through tonight for the Los
Angeles, Ventura, and Santa Barbara county mountains and Cuyama
Valley...

.A very cold storm will continue move through California tonight.
This system will take a mostly over-land trajectory with the best
moisture and upslope flow focused on the north facing slopes and
across eastern Los Angeles County. This system will bring the
coldest temperatures so far this winter season, with snow levels
potentially falling as low as 1500 feet. There could be
significant travel impacts with possible road closures and delays.
Low elevation mountain roadways that could be impacted by snow
showers, icy roads, and strong winds include Interstate 5 near the
Grapevine, Highway 14 through Soledad Canyon, Highway 33 above
Ojai, Highway 154 through the Santa Barbara County mountains, and
Highway 166 through Cuyama Valley. With such low snow levels,
there is also a slight chance of snow showers on today across the
San Luis Obispo county Interior Valleys, Antelope Valley, Santa
Clarita Valley, and the foothills in the Los Angeles and Ventura
County valleys.
