REMARKS:Saturday, a cold front will gradually pass through Louisiana, generating scattered thunderstorms and enhancing atmospheric mixing. In addition, increased cloud cover will limit ozone formation. These conditions will lead to Good AQI levels. Sunday and Monday, light to moderate north-northwesterly winds behind the departing cold front will disperse pollutants and bring clean, cool air into Louisiana. Therefore, despite mostly sunny skies enhancing ozone formation, AQI levels will remain Good on both days.
