The marine layer is back, it has been slow to form, but by morning most of the beach areas should see some stratus. Temperatures will cool significantly Wednesday. There may be a bit more humidity in the air but most pronounced in the southern part of Santa Barbara County.
A little north flow across the Santa Barbara south coast will likely keep that area free of low clouds.
Over the next few days high temperatures will not change much. However, during the weekend, the highs will increase by a few degrees for a slight warm up, but no extreme heat in the forecast.
