Here is this week’s weather forecast by PG&E meteorologist John Lindsey.

Santa Lucia (northeasterly) winds will bring mostly clear skies and warmer conditions to the coastal regions of San Luis Obispo County; however, dense ground fog will continue to develop in the inland valleys during the night and morning hours, burning off to hazy sunshine in the afternoon. The winds will turn onshore later on Martin Luther King Jr. Day, which will allow marine low clouds and fog to develop in the coastal regions overnight into Tuesday morning.

A change in the weather will occur Tuesday afternoon, as a weak cold front will produce increasing clouds with areas of drizzle in the coastal regions.

Dry weather will quickly return Tuesday night and persist through Wednesday as high pressure will briefly rebuild over the Central Coast.

Another but stronger cold front will move through the Central Coast later Thursday into Friday morning with increasing clouds and rain showers. This system should produce between a tenth and a third an inch of rain throughout San Luis Obispo County.

Moderate gale-force to fresh gale-force (32 to 46 mph) northwesterly winds, partly cloudy and cooler weather is expected Friday afternoon and night. These winds will decrease Saturday.

An active weather pattern could bring rounds of rain, mountain snow and breezy southerly winds at times starting the following week as long-range models hint at the possibility of passing storm systems; although, details are still unclear.
