Thursday, as a surface high pressure system traverses the Bayou State, light and variable winds will lead to pollutant build-up. Furthermore, as an upper-level ridge of high pressure passes over the region, atmospheric mixing will be reduced, while mostly sunny skies will promote ozone formation. These conditions will result in high-Good to low-Moderate AQI levels. Friday, a morning temperature inversion will trap pollutants at ground level. Furthermore, as surface high pressure departs the state, light to moderate southerly winds will develop, transporting thin-density smoke from the Gulf into western and southern Louisiana. Additionally, partly sunny skies and warmer temperatures will support ozone development. Thus, AQI levels will remain high-Good to low-Moderate. Saturday, as a low pressure system approaches from the southwest, widespread rain showers will enhance atmospheric mixing and limit ozone formation. In addition, periods of moderate winds will aid pollutant dispersion. As a result, AQI levels will be Good to high-Good.
