San Luis Obispo County is under a frost advisory through 9 a.m. Monday with temperatures expected between 32-35 degrees. Meanwhile, the Santa Ynez Valley has a freeze warning in effect through 9 a.m. for temperatures as low as 29-32 degrees.
With such cold overnight and early morning temperatures, remember to bring pets inside, protect sensitive plants and check on pipes.
Despite the chilly start to Monday, the Central Coast will see mostly sunny skies and pleasant daytime highs for the first week of December thanks to mild offshore flow. Beaches and coastal valleys will be in the low to mid 60s while inland valleys will have highs in the mid to upper 50s.
An upper low is approaching the San Francisco Bay and will begin to make it way toward the Central Coast Tuesday. The northwest tip of SLO County could see rain Tuesday afternoon but it will likely be light and scattered.
The system looks to tap into some southerly flow and is expected to produce rain, albeit scattered, through Thursday. Projected rain totals from the 3-day event are between 1-2 inches. Some forecasts are calling for as much as 3 inches.
Onshore winds will pick up Wednesday with gusts to 30+ mph. The cold core of the system could produce thunderstorms Wednesday night.
Friday will be a transition day with clearing skies. Dry and sunny conditions return heading into the weekend.
