A stronger low pressure system rolls thru the Central Coast Friday night into Saturday. Its associated cold front will zip across the forecast area during Saturday. After a 3 to 5 hour period of generally steady precipitation the system will start to pull out. Most of that rain is late Friday night into Saturday morning diminishing to showers in the early afternoon and should be gone Saturday evening.
I except we will see one quarter to one half inch with local totals up to three quarters of an inch across the higher terrain of northern SLO county the mountains of Santa Barbara county.
Snow levels will be 4000 to 4500 feet tonight and early Saturday then should lower to around 3000 feet by sat evening. Overall expect 3 to 6 inches of snow in the mountains of Santa Barbara county where a winter weather advisory is in place.
There could even be local snow accumulations of an inch or two in the foothills in the Cuyama Valley and the interior valleys of SLO county.
Gusty west to northwest winds will develop across much of the region late Saturday afternoon and evening behind the front. Wind advisories may be needed for the Central Coast. Gusty NW to N winds are also expected to affect locations through and below passes and canyons of the Santa Ynez range in southern Santa Barbara counties Saturday evening probably reaching advisory levels.
It will become quite cold again across the region Saturday night Especially where skies clear and winds diminish. Frost advisories may be needed for the Central Coast and Santa Ynez valley. Having had two nights of hard freezes in the Cuyama Valley and the interior valleys of SLO county freeze and frost products will no longer be necessary for those areas but hard freeze conditions will still be likely.
Skies will be mostly sunny across the region on Sunday but it will remain very chilly. Daytime high temperatures will be 6 to 12 degrees below seasonal norms in most areas but temps do warm to near 70 in coastal valleys for highs by Wednesday.
