Air Quality Forecast and Weather Discussion
Saturday, as a low pressure system moves into northern California, moderate southerly winds will disperse pollutants, and increasing clouds and scattered showers will limit ozone production. As a result, ozone levels will be Good. Sunday and Monday, lighter winds will reduce pollutant dispersion, and slightly warmer temperatures will increase the formation of ozone. However, lingering clouds will limit production, and pollutant carryover from previous days will be low. These conditions will lead to high-Good ozone levels on both days.
