REMARKS:Friday, light to moderate northerly winds will disperse pollutants and bring clean air into Louisiana, leading to Good AQI levels statewide. Saturday, light to moderate east-southeasterly winds will transport a clean air mass into the state, keeping AQI levels Good. Sunday, light winds at the surface will reduce pollutant dispersion. However, an upper-level trough of low pressure will impact Louisiana, increasing mixing in the atmosphere and helping disperse pollutants. Therefore, AQI levels will remain Good.
