Air Quality Forecast and Weather Discussion
Tuesday, cooler temperatures will limit ozone formation in the Sacramento region, and moderate southerly to southwesterly winds will disperse pollutants. In addition, a weak upper-level trough of low pressure passing over northern California will enhance atmospheric mixing. Therefore, ozone levels will be Good. Wednesday and Thursday, warming temperatures will enhance ozone formation, and lighter winds will limit pollutant dispersion. However, pollutant carryover from day to day will be low. As a result, ozone levels will be Moderate on both days.
