Forecast Discussion: Wednesday is a Spare The Air day in the Sacramento region. An upper-level ridge of high pressure over northern California will limit atmospheric mixing and produce mostly sunny skies and hot temperatures, enhancing the formation of ground-level ozone. Furthermore, light southwesterly winds will limit pollutant dispersion. As a result, ozone levels will be Unhealthy for Sensitive Groups. Thursday and Independence Day, the upper-level ridge will weaken, increasing atmospheric mixing and producing light to moderate onshore winds. In addition, slightly cooler temperatures and increasing clouds will reduce ozone formation. These conditions will lead to Moderate ozone levels on both days.
