A cold front will bring variable amounts of clouds to the Central Coast through Sunday afternoon. This condition will produce slightly warmer overnight temperatures, but cooler highs during the afternoon hours due to increased cloud cover. Snow levels may drop to near 4,000 feet in the Lake Tahoe area Saturday night into Sunday morning.

A strong high-pressure ridge will develop off the Northern California coastline and the Great Basin later on Sunday into Monday. This system will produce fresh to strong (19 to 31 mph) Santa Lucia (northeasterly) winds on Sunday afternoon into Sunday night, increasing to strong to gale-force (25 to 38 mph) levels with gust to 55 mph in some of the coastal canyons and passes on Monday into Tuesday morning.

A cooler air mass will filter into the Central Coast later on Sunday into Monday and combined with clear skies will produce frigid overnight lows in the inland valleys, especially in the wind sheltered areas on Monday, Tuesday and Wednesday. In fact, overnight temperatures will drop the mid to high- 20s in the inland valleys on Tuesday and Wednesday. High temperatures will increase to the mid to high 60s in the inland valleys and 70s in the coastal valleys and along the beaches over this timeframe. Dry weather with areas of morning ground fog is forecast for all of next week with the next chance of rain developing on Dec. 12.

This Week’s PG&E Safety Tip

At PG&E, the safety of our customers and employees is our top priority. Buckling up is such a simple thing to do; it only takes two seconds, and no other single action has as much lifesaving potential. If more adults wore safety belts, their kids would, too. Besides, it’s the law.
