Sharp Sunday Cooldown Set for California’s Central Coast

Overview

• Forecasters expect a notable weekend cool-down across San Luis Obispo and Santa Barbara Counties, with the biggest temperature drops inland.
• Highs during the coldest stretch should fall to the upper 50s at the coast and the 60s inland, with gusty southwest winds over mountain and interior areas.
• The marine layer, which is a shallow pool of cool, moist ocean air, will bring night and morning low clouds and fog to about 2,500 feet before daytime clearing.
• A cut-off low could produce spotty light showers late in the weekend into early next week, with most places seeing little or nothing and northwest San Luis Obispo County holding the best chance for a few hundredths of an inch, up to 0.10–0.20 inch in a worst case.
• High pressure is forecast to rebuild by mid-week, returning dry weather and a warmup that pushes the Paso Robles area back into the mid-70s to upper-80s by late week.
