REMARKS:Monday, calm overnight and morning winds have limited pollutant dispersion over much of Louisiana, and areas of fog and mist have enhanced particle formation. Therefore, despite moderate northeasterly winds dispersing some pollutants this afternoon, AQI levels will be low-Moderate in most cities. Tuesday and Wednesday, mostly sunny skies and warmer temperatures will support ozone formation, and a humid air mass will aid the production of particles. In addition, light east-northeasterly winds will reduce pollutant dispersion. These conditions, combined with pollutant carryover from day to day, will keep AQI levels low-Moderate in most cities on both days.
