The Central Coast can expect partly cloudy skies with temperatures a few degrees above normal through the weekend.
Thick low clouds and fog will likely develop in eastern San Luis Obispo County and Cuyama Valley Saturday night into Sunday morning.
Offshore breezes have been generally light with gusts in the 20 to 25 mph range and will bring high temperatures into the low to mid 70’s across interior valleys through Monday.
Starting Christmas Day, cooler temperatures return as a low-pressure system passes through the area. Late Monday through Tuesday, rain is possible. The American GFS model indicates some areas seeing no rain and others seeing a few hundredths of an inch. The European model sees as much as 0.50” at some coastal areas.
Dreaming of a wet Christmas? This forecast image from the Weather Prediction Center (@NWSWPC) has much of our area getting around 0.10" of rain on Tuesday. Snow levels are about 5,000' so possibly some white stuff in the mountains, too. #LAweather pic.twitter.com/IcBVRXIxCn

The most significant impact with this system will be the threat of strong northwest to north winds. Strong and potentially danging wind gusts will reach 40 to 60 mph across portions of southwestern California late Monday night into Christmas Day.
