Ozone and PM2.5 Air Quality Index (AQI) Forecast
Issued: Friday, March 31, 2023, 2:30 PM
Friday, as a cold front moves into the Bayou State, increasing clouds and rain showers will reduce ozone formation. In addition, strengthening southerly winds will enhance mixing and dispersion. However, these winds will also transport smoke from the western Gulf into Louisiana, increasing particle levels. Therefore, AQI levels will be high-Good to low-Moderate. Saturday, lighter northwesterly winds behind the departing front will limit pollutant dispersion. Furthermore, increasing sunshine will enhance ozone formation. These conditions will keep AQI levels high-Good to low-Moderate. Sunday, strengthening southeasterly to southerly winds will aid mixing and dispersion over Louisiana. Furthermore, increasing clouds and thunderstorms in the afternoon will limit ozone production. Therefore, AQI levels will be Good throughout the state.
