REMARKS:Friday, surface high pressure over the southeastern U.S. will reduce mixing and generate light winds throughout Louisiana, inhibiting pollutant dispersion. As a result, AQI levels will be Good to low-Moderate statewide. Saturday and Sunday, southerly winds will strengthen as a low pressure system approaches from the west. These winds will aid pollutant dispersion and transport a cleaner air mass into Louisiana, yielding Good AQI levels on both days.
