REMARKS: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 be Good. Sunday, light winds early in the day will reduce pollutant dispersion. However, moderate southerly winds will develop in the afternoon ahead of another approaching cold front, dispersing pollutants and keeping AQI levels Good in most cities. Monday, the cold front will move into Louisiana, generating moderate southwesterly winds that will disperse pollutants, and mostly cloudy skies, rain showers, and thunderstorms that will reduce ozone formation. Therefore, AQI levels will be Good.
