REMARKS:Sunday, warm temperatures and partly to mostly sunny skies will support ozone production in Louisiana. However, light southeasterly to easterly winds will aid pollutant dispersion, and isolated thunderstorms will increase atmospheric mixing. These conditions will lead to Good to Moderate AQI levels. Monday and Tuesday, a surface high pressure system over the south-central U.S. will generate light to moderate northerly winds, continuing to aid pollutant dispersion. In addition, a front moving through Louisiana will lead to cooler temperatures across the state, limiting ozone formation. Therefore, AQI levels will be Good in most locations on both days.
