Air Quality Forecast and Weather Discussion
Monday, moderate and gusty north-northwesterly winds through the Sacramento Valley will increase mixing in the atmosphere. Therefore, despite warm temperatures and sunny skies enhancing ozone formation, ozone levels will be Good. Tuesday, northwesterly winds will weaken in the Sacramento region, reducing pollutant dispersion. Furthermore, sunshine and temperatures in the mid-80s will continue to 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, northwesterly winds will re-develop in the afternoon, dispersing pollutants and yielding low-Moderate ozone levels.
