Ozone and PM2.5 Air Quality Index (AQI) Forecast
Issued: Friday, May 27, 2022, 2:30 PM
Friday, mostly sunny skies and temperatures around 85-90F will aid ozone formation across the Bayou State, while lingering smoke from regional burning will enhance ozone production. Therefore, despite moderate and gusty northwesterly winds aiding dispersion in the latter portion of the day, AQI levels will be mid- to high-Moderate in southern Louisiana, with Good AQI levels elsewhere. Saturday and Sunday, upper-level high pressure moving across the state will reduce atmospheric mixing. At the surface, light and variable winds will hinder dispersion, while sunny skies and warm temperatures promote ozone formation. Additionally, smoke transport from the Gulf of Mexico will continue to enhance ozone production. Thus, AQI levels will be Unhealthy for Sensitive Groups on both days for Baton Rouge and New Orleans, with Moderate AQI levels elsewhere.
