Here is this week’s weather forecast by PG&E meteorologist John Lindsey:
Gentle to moderate (8- to 18-mph) northeasterly (Santa Lucia) winds will produce dry and fair conditions today as a transitory ridge of high pressure moves over the Central Coast.
A low-pressure system will drop south out of the Gulf of Alaska and slowly move toward San Luis Obispo County through Tuesday, delivering persistent northwesterly winds, night and morning low clouds and fog, and cooler temperatures.
The associated cold front will move over the Central Coast on Wednesday with moderate to fresh (13- to 24-mph) southeasterly winds and widespread rain showers. Cold and unstable air behind the front will produce the potential for thunderstorm activity.

Snow levels will start out near 5,500 feet and fall to near 3,500 feet by Wednesday night. Overall, this does not look like a major rainmaker, with only about 0.25 to 0.50 inches expected for Wednesday.
New snow accumulations are likely to range from 6 to 8 inches across the central and southern Sierra.
A chance of rain showers and afternoon thunderstorm activity will continue along the Central Coast, along with snow in the Sierra, through Thursday.
Beginning Friday, a high-pressure ridge will build over the western United States, signaling a return to dry and mild conditions across San Luis Obispo County through the weekend. Unsettled weather is then set to return toward the middle of the following week.
