REMARKS:Friday and Saturday, moderate southerly to southeasterly winds will persist over the majority of the state, dispersing pollutants. In addition, mostly cloudy skies and widespread rain showers will limit ozone formation statewide. Therefore, despite southerly winds transporting regional pollutants from the western Gulf of Mexico into Louisiana, AQI levels will be Good in most locations on both days. Sunday, a cold front will move across Louisiana, producing widespread showers and thunderstorms and shifting winds to northerly. These conditions will keep the low levels of the atmosphere well mixed and transport a clean air mass into the state. As a result, AQI levels will be Good.
