A gradual cooling trend is expected through mid-week, as the marine layer forms overnight. This will bring a pattern of night to morning fog and stratus clouds, with afternoon sunshine. As breezy to gusty northwest winds remain throughout the week this will help push away low level clouds. The strongest winds will likely impact southern Santa Barbara County coastal and mountain areas.
Due to a broad trough temperatures cooled down on Tuesday. Overall the forecast was mostly sunny aside from the stratus clouds. As the broad trough sweeps across the area we're expecting a deeper marine layer leading to further cooling on Wednesday. Highs will warm in the 60s to 70s near coastline, 70s to 80s across the interior valleys.
The main story will continue to be the winds, with a strong northwesterly flow going into Wednesday. A Wind Advisory is in effect across southern Santa Barbara County coastal and mountain areas through Wednesday at 3 AM. North winds will range between 20 to 30 mph and gusts could amount up to 50 mph. The strongest winds anticipated west of the Santa Barbara Airport.
Otherwise onshore flow could prompt southwesterly winds especially near San Luis Obispo County and the Central Coast. Daytime highs will range near average, with little day to day changes.
A weak system will drop a trough into Saturday, prompting cooler temperatures. The area of low pressure is expected to shift east. This will lead to a warming trend from Memorial Day into Tuesday.
