Air Quality Forecast and Weather Discussion
Wednesday through Friday, upper-level high pressure west of the Sacramento Valley will hinder vertical mixing in the atmosphere. In addition, light and variable winds will inhibit pollutant dispersion, and cool temperatures each night will generate an inversion, trapping pollutants near the ground. As a result, particle levels will be Moderate on all three days, while ozone levels will be high-Good on Wednesday and low-Moderate on Thursday and Friday.
