REMARKS:Monday, light morning winds will limit pollutant dispersion in Louisiana, and widespread fog and mist will enhance particle production. However, moderate southerly winds will develop ahead of an approaching cold front in the afternoon, helping to disperse pollutants. As a result, AQI levels will be Good to Moderate across the state. Tuesday, the cold front will move into Louisiana from the northwest, enhancing vertical mixing, producing widespread showers and thunderstorms, and generating moderate winds statewide. These weather conditions will effectively disperse pollutants, yielding Good AQI levels. Wednesday, moderate west-northwesterly winds behind the departing cold front will disperse pollutants and bring clean air into Louisiana, keeping AQI levels Good across the state.
