REMARKS:Thursday, light winds through the morning hours will reduce pollutant dispersion, and sunny, warm conditions will support ozone production. However, moderate southeasterly winds will disperse pollutants in the afternoon, causing AQI levels to be high-Good to low-Moderate in most cities. Friday, moderate and gusty south-southeasterly winds will develop ahead of an approaching cold front, dispersing pollutants. Furthermore, increasing clouds and rain showers will reduce ozone formation. These conditions will lead to Good AQI levels statewide. Saturday, as a cold front moves into Louisiana, moderate southwesterly winds will disperse pollutants, and mostly cloudy skies, rain showers, and thunderstorms will reduce ozone formation. Therefore, AQI levels will remain Good.
