REMARKS:Sunday and Monday, high pressure over Louisiana will generate light winds, limiting pollutant dispersion. In addition, partly to mostly sunny skies will enhance ozone production. Therefore, AQI levels will be Moderate across Louisiana on both days. Tuesday, mostly sunny skies will aid ozone formation in Louisiana. In addition, regional pollutant carryover from previous days will be high. Despite scattered thunderstorms dispersing some pollutants in the afternoon hours, AQI levels will be Moderate statewide.
