REMARKS:Saturday, light and variable winds will reduce pollutant dispersion, and mostly sunny skies and warm temperatures will enhance ozone formation in Louisiana. These conditions will result in mid- to high-Moderate AQI levels statewide. Sunday, calm winds becoming light southerly will continue to inhibit pollutant dispersion. Therefore, despite increasing clouds limiting ozone formation, AQI levels will continue to be Moderate for all cities. Monday, light southerly winds will gradually bring cleaner air into southern Louisiana. However, pollutant carryover from Saturday and Sunday will keep AQI levels Moderate statewide.
