REMARKS:Friday and Saturday, light winds will reduce pollutant dispersion, and sunny, warm conditions will enhance ozone formation throughout Louisiana. As a result, AQI levels will be Moderate in most cities on both days, with high-Moderate AQI levels expected in Baton Rouge on Saturday. Sunday, an upper-level ridge of high pressure will build over Louisiana, reducing atmospheric mixing. In addition, mostly sunny skies and warm temperatures will continue to enhance ozone formation. These conditions will keep AQI levels Moderate.
