Air Quality Forecast and Weather Discussion
Tuesday is a Spare The Air Day in the Sacramento region. An upper-level ridge of high pressure will reduce atmospheric mixing and produce sunny skies with temperatures near 105F. Furthermore, smoke from the Six Rivers Complex Fire will impact the region, enhancing ground-level ozone formation. In addition, a light delta breeze will reduce dispersion, allowing pollutants to accumulate in the Sacramento area. As a result, ozone levels will be Unhealthy for Sensitive Groups. Wednesday and Thursday, hot conditions will persist, supporting ozone production. Furthermore, light onshore winds early each day will continue to limit pollutant dispersion. Therefore, despite moderate onshore winds dispersing pollutants each afternoon, ozone levels will remain Unhealthy for Sensitive Groups on both days.
