Air Quality Forecast and Weather Discussion
Wednesday and Thursday, warming temperatures will support ozone formation, and lighter winds will limit pollutant dispersion in the Sacramento region. However, pollutant carryover from day to day will be low. As a result, ozone levels will be Moderate on both days. Friday, an upper-level ridge of high pressure will move over northern California, reducing atmospheric mixing and generating sunny skies and hot temperatures. These conditions will enhance ozone formation. Therefore, despite light to moderate onshore winds in the afternoon aiding pollutant dispersion, ozone levels will be Unhealthy for Sensitive Groups.
