Sunday, an upper-level ridge of high pressure will hinder atmospheric mixing over Louisiana. Furthermore, mostly sunny skies and highs in the mid- to upper-80s will enhance ozone production. In addition, light southerly winds will limit dispersion and gradually bring thin-density smoke into the state. These conditions will lead to high-Good to low-Moderate AQI levels in most locations, with mid-Moderate AQI levels expected in Baton Rouge and New Orleans. Monday and Tuesday, mostly sunny skies and temperatures in the mid- to upper-80s will continue to support ozone formation across the Bayou State. Additionally, calm morning winds will lead to pollutant build-up each day, especially over the southeastern portion of the state. However, south-southeasterly winds will strengthen each afternoon as an area of low pressure develops to the west, enhancing pollutant dispersion. These conditions will keep AQI levels high-Good to low-Moderate in most locations on both days.
