Here is this week’s weather forecast by PG&E meteorologist John Lindsey.
Despite cloudy skies, many locations along the Central Coast reported low-80-degree readings yesterday.
A weak 1,017-millibar low-pressure system and associated cold front is forecast to move over San Luis Obispo County this morning, with extensive clouds, fog and a few areas of drizzle. Today’s maximum temperatures should range from the low to mid-70s.
Never miss a local story.
High pressure is forecast to re-establish itself over the Great Basin later tonight into Tuesday. This condition should produce moderate to fresh (13- to 24-mph) Santa Lucia (northeasterly) winds tonight into Tuesday morning.
The strongest winds are expected to occur along Highway 41 from Morro Bay High School heading toward Atascadero, about halfway up the grade. The coastal canyons and parts of eastern San Luis Obispo, including Cal Poly, San Luis Obispo High School and French Hospital, could also experience gusty winds. These winds should produce clear skies, with temperatures mostly in the low 70s. Temperatures are forecast to warm to the mid- to high 70s on Wednesday.
Another high-pressure ridge is forecast to build over California later this week. This high-pressure ridge will produce an extended period of dry weather with above-normal temperatures through March 20.
