REMARKS:Thursday, increasing sunshine will enhance ozone formation in the southeastern portion of the state. However, light to moderate northeasterly winds will keep pollutants well dispersed, yielding Good AQI levels. Friday, lighter winds will reduce pollutant dispersion, and sunny, warm conditions will enhance ozone formation. Therefore, AQI levels will be Good to low-Moderate statewide. Saturday, a front will move through Louisiana, enhancing mixing in the atmosphere and generating moderate northerly winds at the surface. These conditions will aid pollutant dispersion. In addition, cloudy skies will reduce ozone formation. As a result, AQI levels will be Good.
