REMARKS:Sunday through Tuesday, surface high pressure over Louisiana will generate calm to light winds, limiting pollutant dispersion. In addition, warm temperatures and partly to mostly sunny skies will support ozone formation. However, isolated thunderstorms will enhance vertical mixing. Therefore, AQI levels will be Good to low-Moderate on all three days, with Moderate AQI levels expected in the Baton Rouge area.
