REMARKS:Saturday and Sunday, mostly cloudy skies will limit ozone production, and widespread thunderstorms will aid atmospheric mixing in Louisiana. However, light winds will reduce pollutant dispersion at the surface, and lingering Saharan dust will increase particle concentrations. As a result, AQI levels will be Good to low-Moderate on both days. Monday, easterly winds will strengthen, aiding pollutant dispersion. Therefore, despite increasing sunshine enhancing ozone levels in some areas, AQI levels will remain Good to low-Moderate.
