The marine layer is back along the coast Wednesday morning. Westerly winds have pushed the fog over area beaches in San Luis Obispo County. The marine layer is expected to mix out by the afternoon, but it will likely be met with continued smoky and hazy skies, which will also be present across coastal and inland valley communities. As a result, an air quality alert will remain in place through September 10 as smoke continues to drift into the area from the Dolan Fire that is burning in Monterey County.
Santa Barbara County, while not under an alert, will also experience moderate air quality Wednesday. Anyone with pre-existing health conditions may want to consider limiting his or her time outside.
Southwesterly winds are expected to reach 10-15 miles per hour across the interior valleys Wednesday, with wind gusts up to 20 mph. The interiors are also returning to near-seasonal temperatures, which means most daytime highs will stay close to the low 90s.
For the coastal valleys, temperatures will continue to range from the mid-70s to the low 80s. The coolest weather will be towards the coast where temperatures will be in the 60s and 70s. The Gaviota coast will have winds from the northwest and the Santa Barbara coast will have winds shifting out of the southeast. Both the satellite radar and microclimate model weren't picking up much cloud cover along the south coast, but smoky and hazy conditions are expected in that area Wednesday.
As far as fire weather is concerned, offshore winds will be weaker Wednesday but low relative humidity remains a factor that elevates fire weather.
