Weather Watch

San Luis Obispo County weather forecast for the week of March 9

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

Marine low clouds and fog will persist during the night and morning hours, clearing during the afternoon hours along the coastal regions. In the North County, skies will remain mostly clear. Today’s maximum temperatures will range from the 60s along the beaches to the high 70s in the coastal valleys and low 80s in the North County.

An upper-level low-pressure system laden with subtropical moisture will produce increasing clouds, gentle southerly winds and mild overnight lows and daytime highs Tuesday. As the system moves over the Central Coast, scattered rain showers will develop throughout San Luis Obispo and Santa Barbara counties Wednesday. Rainfall amounts will be less than a quarter of an inch. Snow levels will be near 7,000 feet in the Sierra Nevada and Tehachapi mountains.

Dry conditions will return Thursday as high pressure will quickly build over the state. Temperatures will rise back to above-normal Friday into Saturday as the Santa Lucia (northeasterly) winds return during the night and morning hours. In fact, maximum temperatures may reach record levels Friday and Saturday, with some locations reaching near 90 degrees. Warm, indeed, for early March.

The longer-range models are indicating a chance of rain Sunday.

At PG&E, your safety is our first concern. 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.
