Forecast Discussion: Today, an upper-level ridge of high pressure over the southwestern U.S. will limit vertical mixing in the atmosphere and produce sunny skies and hot temperatures in the Imperial Valley. These conditions will enhance ground-level ozone formation. Furthermore, light west-northwesterly winds will limit pollutant dispersion and gradually transport additional pollutants into the region. As a result, ozone levels will be Moderate. Tomorrow, upper-level high pressure will remain over the southwestern U.S., limiting vertical mixing and producing mostly sunny skies and hot temperatures. These weather conditions will continue to enhance ozone formation. In addition, light southerly winds will limit the dispersion of pollutants. Therefore, ozone levels will remain Moderate.
