REMARKS:Wednesday, a cold front will move through Louisiana, enhancing vertical mixing in the atmosphere and generating moderate to strong winds at the surface. These conditions will disperse pollutants, yielding Good AQI levels statewide. Thursday, winds will weaken behind the departing cold front, reducing pollutant dispersion. However, low pollutant carryover from the previous day will keep AQI levels Good. Friday, light to moderate north-northeasterly winds will bring a clean, cool air mass into Louisiana, leading to continued Good AQI levels throughout Louisiana.
