The Central Coast still sits in a trough over the West and a number of small disturbances still look to rotate thru the area into later Sunday. That will keep on and off showers in play. The total amount of additional rain looks to stay under .50” but the airmass will get cold. That means snow levels will drop from about 5000ft down to 1500 or perhaps lower Sunday.
Snow levels that low could put snow in the hills of both SLO and SB counties and some valley snow showers are not out of the question.
