REMARKS:Independence Day and Sunday, generally light south to southwesterly winds will gradually bring Saharan dust into Louisiana, and fireworks displays may cause locally elevated particle concentrations. Therefore, despite enhanced atmospheric mixing associated with scattered showers and thunderstorms helping to disperse some pollutants, AQI levels will be Moderate for particles statewide on both days. Monday, light to moderate south-southwesterly winds will continue to transport Saharan Dust into Louisiana. Furthermore, mostly sunny skies and warm temperatures will aid ozone formation. As a result, AQI levels will be Moderate throughout the state.
