Air Quality Forecast and Weather Discussion
Tuesday, northwesterly winds will weaken in the Sacramento region, reducing pollutant dispersion. Furthermore, sunshine and temperatures in the mid-80s will support ozone production. These conditions will lead to Moderate ozone levels. Wednesday, light winds through the morning hours will continue to limit mixing and dispersion. However, moderate northwesterly winds will develop in the afternoon, dispersing pollutants and yielding high-Good ozone levels. Thursday, moderate north-northwesterly winds will keep pollutants well dispersed in the Sacramento region, leading to Good ozone levels.
