REMARKS:Thursday through Saturday, a strong upper-level ridge of high pressure over Louisiana will reduce atmospheric mixing and produce mostly sunny skies, enhancing the formation of ground-level ozone. Furthermore, surface high pressure persisting over southeastern Louisiana will produce light southerly winds, limiting pollutant dispersion and gradually transporting Saharan Dust into the state. These conditions, combined with pollutant carryover from day to day, will result in Moderate AQI levels in most cities on all three days.
