Ozone and PM2.5 Air Quality Index (AQI) Forecast
Issued: Monday, January 25, 2021, 2:30 PM
Monday, gusty southerly winds will keep pollutants well dispersed across southern portions of the Bayou State, while northern portions experience a clean air mass arriving behind a cold front. Therefore AQI levels will be Good statewide. Tuesday, a front will stall across southern portions of Louisiana, producing light winds. In addition, high relative humidity will enhance particle formation across southern Louisiana, leading to low-Moderate AQI levels. Farther north, light northeasterly winds will continue to transport clean air into the region, resulting in another day of Good AQI levels. Wednesday, a cold front will move through the entire state by midday. Behind the front, northerly winds will enhance pollutant dispersion, and keep AQI levels Good statewide.
