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

Weather report

A major change in the weather pattern will develop today as a vigorous 994-millibar surface low-pressure system with significant upper-level wind support drops out of Washington state and moves south along the California-Nevada state line. 

This system will produce strong to gale-force (25- to 38-mph) northwesterly winds and partly to mostly cloudy skies throughout San Luis Obispo County. Areas of drizzle and a few light showers are forecast to develop today. Maximum temperatures will reach the mid-60s.

Partly cloudy skies with scattered light rain showers and cool conditions will continue through Tuesday morning. Snow levels in the Sierra Nevadas will drop near to 5,500 feet with new snow accumulations of 2 and 4 inches above 5,500 feet and as much as 8 inches above 6,000 feet. 

Total rainfall amounts in San Luis Obispo County are expected to range between 0.02 and 0.10 of an inch by Tuesday morning. Overnight minimum temperatures will be the lowest of the fall season, with minimums in the 30s and 40s on Tuesday and Wednesday morning.

A slow warming trend with dry weather will start Wednesday and will continue through Friday. 

At this time, another low-pressure system will produce cooler conditions for the weekend. However, rain is not expected.

Today’s surf report

Strong to gale-force (25- to 38-mph) northwesterly winds will generate 6- to 8-foot northwesterly (320-degree deep-water) sea and swell (with a 4- to 11-second period) this morning, decreasing to 5 to 7 feet by this afternoon and tonight.

A 3- to 5-foot northwesterly (300-degree deep-water) swell (with an 8- to 11-second period) is forecast along the Central Coast on Tuesday and will remain through Saturday.

Increasing northwesterly winds and sea and swell is forecast along the coastline Sunday and next Monday.

Seawater temperatures will range between 54 and 57 degrees through Friday.
