Air Quality Forecast and Weather Discussion
Wednesday through Friday, an upper-level trough of low pressure will move toward the Sacramento Valley, increasing vertical mixing in the atmosphere. Furthermore, light to moderate onshore winds will increase pollutant dispersion, and cooler temperatures on Wednesday and Thursday will hinder ozone formation. These conditions will lead to high-Good to low-Moderate ozone levels on all three days.
