Friday evening forecast – Sep.19th
Strengthening onshore flow beneath broad troughing over the West Coast will bring a cooling trend through Monday. Night through morning low clouds and fog will expand into most coastal and lower valley areas by Monday. Gusty northerly winds are expected across southern Santa Barbara County through Saturday morning. A warming trend is possible for the latter half of next week as ridging aloft settles into the region.
Better air quality and clearer conditions are expected for the weekend. Highs will be cooler in the 60s for the coastal cities of San Luis Obispo County, 70s for Santa Barbara & Ventura counties beaches and 80s inland.
Marginally gusty Sundowner winds are already occurring this afternoon and will increase across southern Santa Barbara County later and linger into Saturday morning. A wind advisory remains in effect through 9 am PDT Saturday morning. Gusts up to 45 mph are possible, especially west of Goleta out toward the Gaviota area.
Sunday we expect the return of the marine layer in the morning. The cooling trend continues through Monday with warmer weather returning by the middle of next week.
