Ozone and PM2.5 Air Quality Index (AQI) Forecast
Issued: Wednesday, December 4, 2024, 5:32 PM
Wednesday, light to moderate southeasterly winds will recirculate pollutants across the Bayou State as a cold front approaches Louisiana. In addition, increasing relative humidity will promote particle formation as rain showers move across the state. Therefore, AQI levels will be low-Moderate. Thursday, overnight and early morning rainfall will aid atmospheric mixing as the cold front moves across the region. In addition, northerly to north-northeasterly winds behind the departing front will enhance dispersion and transport cleaner air into the state throughout the day. As a result, AQI levels will be Good statewide. Friday, decreasing northeasterly winds will reduce dispersion as a surface high pressure system moves into Arkansas. In addition, smoke from agricultural fires may contribute to particle levels, leading to high-Good to low-Moderate AQI levels in most locations.
