REMARKS:Wednesday, light northwesterly winds will help to disperse pollutants in Louisiana. However, mostly sunny skies and warm temperatures will support ozone production. These conditions will lead to Moderate AQI levels across most of the state, with high-Moderate AQI levels expected in Baton Rouge. Thursday and Friday, increasing clouds and thunderstorms will reduce ozone production, and light northwesterly winds will aid in pollutant dispersion. Therefore, AQI levels will be Good to low-Moderate statewide on both days.
