REMARKS:Monday, widespread thunderstorms and cloudy skies will limit ozone production in Louisiana. In addition, light to moderate easterly winds will disperse pollutants. Therefore, AQI levels will be Good. Tuesday, overcast skies will continue to limit ozone formation, and thunderstorms will keep the atmosphere well mixed. As a result, AQI levels will remain Good. Wednesday, increasing sunshine will aid ozone production. However, moderate northwesterly winds behind a departing cold front will disperse pollutants and bring clean air into Louisiana, keeping AQI levels Good.
