A vigorous cold front strengthened by upper-level winds will move through the Central Coast on Sunday morning from the north to the south, bringing southerly winds, moderate rain and possible isolated thunderstorms through the afternoon.
The weather front will reach Cambria by 8 a.m., San Luis Obispo by 9 a.m. and Nipomo by 10 a.m., bringing widely scattered rain showers and gale-force winds of 32 to 46 mph with gusts of 50 mph along the coastline. Total rainfall amounts will range between a quarter-inch and a half-inch for much of the Central Coast. Cooler air temperatures are expected on Sunday afternoon and night.
The winds will generate a 15- to 17-foot northwesterly ocean swell Sunday afternoon into Monday morning.
This system will also produce snow for the Sierra Nevada above 4,000 feet.
