Detailed forecast:
An extended period of below-normal temperatures is expected over the next several days, as the region remains under a persistent troughing pattern featuring multiple low-pressure systems.
Saturday through Monday, temperatures will trend downward as a trough drops across the region.
Temperatures will bottom out on Monday and highs will struggle to reach even the mid-70s across much of the region.
Many valleys, deserts, and mountains will be upwards of 20 degrees below normal at this time.
Winds will be minimal through Sunday afternoon. Gusty northwesterly winds will occur across the Santa Barbara Southwestern Coast during the evenings Sunday and Monday, leading into a widespread westerly wind event Monday with the passage of the trough.
Marine layer clouds will continue to deepen over the next few days and will extend across most valleys and foothills by Sunday morning.
Additionally, the trough will lift and deepen the marine layer, resulting in a slight chance of drizzle Sunday morning, followed by a better chance Sunday night into Monday.
The highest chance of light rain will be on Monday morning for the northwestern portion of San Luis Obispo County, which will be closer to the center of the low-pressure system.
On Tuesday, following the passage of the first upper low, temperatures will trend upwards a few degrees.
