REMARKS:Friday, light to moderate northerly winds will help to disperse pollutants in Louisiana. Therefore, despite some morning fog and mist enhancing particle production in southeastern Louisiana, AQI levels will be low-Moderate in Baton Rouge and Lafayette and Good elsewhere in the state. Saturday, lighter winds will reduce pollutant dispersion across Louisiana, and mostly sunny skies will aid ozone formation. As a result, AQI levels will be low-Moderate across most of the state. Sunday, 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 remain Moderate across most of Louisiana.
