REMARKS:Tuesday, light to moderate north-northwesterly winds behind a departing low-pressure system will bring a cool, clean air mass into Louisiana. Therefore, AQI levels will be Good throughout the state. Wednesday, a cold front will approach and move through Louisiana late in the day, producing moderate southwesterly winds and increasing vertical mixing in the atmosphere. These weather conditions will effectively disperse pollutants, yielding Good AQI levels statewide. Thanksgiving Day, light to moderate northerly winds behind the departing cold front will disperse pollutants and transport a cool, clean air mass into Louisiana. As a result, AQI levels will remain Good across the state.
