Ozone and PM2.5 Air Quality Index (AQI) Forecast
Issued: Monday, January 30, 2023, 2:30 PM
Monday, a stationary front over southeastern Louisiana will produce southwesterly winds to the south and northerly to northeasterly winds to the north and west. The air mass south of the front contains a thin plume of smoke from seasonal agricultural burning in eastern Mexico, while the air mass to the north is much cleaner. Areas along and north and west of the front will also see increased atmospheric mixing from periods of rain. As a result, AQI levels will be Good across much of the Bayou State, while southeastern Louisiana is expected to have high-Good AQI levels. Tuesday and Wednesday, as the front slowly advances southward, northerly to northeasterly winds will gradually disperse pollutants and bring clean into the state, yielding Good AQI levels in most cities on both days. However, lingering smoke will lead to high-Good AQI levels in southeastern Louisiana on Tuesday before AQI levels improve to Good there on Wednesday.
