Air Quality Forecast and Weather Discussion
Tuesday, as an upper-level ridge of high pressure begins to build over northern California, warming temperatures will gradually increase ozone formation. However, light to moderate northwesterly winds through the Sacramento Valley will aid pollutant dispersion, leading to Good ozone levels. Wednesday and Thursday, light and variable winds will reduce pollutant dispersion, and mostly sunny skies and warm temperatures will enhance ozone formation. As a result, ozone levels will be Moderate on both days.
