Forecast Discussion: Very light winds on Thursday with near normal temperatures under mostly sunny skies combine to raise ozone into the Moderate range. Increasing south and southeasterly winds on Friday usher in cleaner ocean air. Additionally, cloud development by afternoon will further reduce pollution levels resulting in upper Good air quality. Clouds dominate on Saturday with cleaner flow from the ocean continuing, resulting in Good air quality. - MDE
