Weather Conditions:
Friday, as an upper-level ridge over California weakens, light to moderate onshore winds will help to disperse pollutants, and increasing clouds will limit ozone formation. Therefore, ozone levels will be Moderate. Saturday and Sunday, sunny, warm conditions will enhance ozone formation in the Sacramento region; however, moderate onshore winds will continue to disperse pollutants. As a result, ozone levels will be low-Moderate on both days.
