REMARKS:Wednesday, mostly sunny skies and warm temperatures will enhance ozone formation across Louisiana. Therefore, despite light to moderate northeasterly winds dispersing some pollutants, AQI levels will be low- to mid-Moderate in most cities. Thursday and Friday, increasing cloud cover and scattered thunderstorms will reduce ozone formation across Louisiana. However, light winds will reduce pollutant dispersion, yielding low-Moderate AQI levels across most of Louisiana on both days.
