Monday and Tuesday will see reoccurring clouds and fog in coastal and inland valleys as westerly winds pick up.
Temperatures for Tuesday will be close to normal: mid-60s for coastal areas and mid-70s for the interior.
But by Wednesday, temperatures look to take on a cooling trend as a low-pressure system brings a deepened marine layer and chance of rain Wednesday night into late Thursday.
A Small Craft Advisory is in effect until Tuesday at 3 a.m. from Point Piedras Blancas to Point Sal.
Tuesday through Wednesday looks to be mostly cloudy, with a moist air mass moving into the area.
Rain is expected as early as noon Thursday for northern San Luis Obispo County and has the potential for thunderstorms in those areas.
The bulk of the rain arrives Wednesday night into Thursday and continues throughout the day.
Rainfall amounts are not consistent across different models, the National Weather Service says a storm like this typically brings 0.25″-0.50″ of rain in the coast and valleys and up to 1″ in higher elevations.
More than 1″ of rain in foothills and mountains cannot be ruled out.
Winds will be another thing to watch. Gusts 35 to 50 mph are possible ahead of and behind this cold front especially in mountains.
NWS is also saying this storm is unusual for this time of year.
Unsettled weather looks to continue into the weekend with the potential for another storm system Saturday and Sunday, but this one looks to be weaker.
