REMARKS:Tuesday, mostly sunny skies and temperatures in the 90s will support ozone production, and Saharan dust will increase particle levels. Furthermore, light winds will limit pollutant dispersion, especially in the northern portion of the state. As a result, AQI levels will be Moderate in most cities. Wednesday and Thursday, scattered thunderstorms will reduce ozone formation, and light to moderate southerly winds will help to disperse pollutants. However, these winds will also transport Saharan dust into Louisiana. Therefore, AQI levels will remain Moderate statewide on both days.
