REMARKS:Saturday, light winds this morning have locally reduced pollutant dispersion. However, moderate southeasterly winds this afternoon will help to disperse pollutants. As a result, AQI levels will be Good to low-Moderate throughout Louisiana. Sunday and Memorial Day, cloud cover and scattered thunderstorms will inhibit ozone formation across Louisiana. In addition, moderate and occasionally gusty southeasterly winds will help to disperse pollutants. Therefore, AQI levels will be Good statewide on both days.
