REMARKS:Tuesday, moderate north-northeasterly winds behind a departing cold front will disperse pollutants and transport clean air into Louisiana, leading to Good AQI levels. Wednesday and Thanksgiving Day, lighter easterly to northeasterly winds will reduce pollutant dispersion. However, a clean, dry air mass over the region will keep AQI levels Good in most cities on both days.
