REMARKS:Wednesday and Thursday, light easterly winds will reduce pollutant dispersion across Louisiana. However, low pollutant carryover from previous days will result in Good to low-Moderate AQI levels statewide on both days. Friday, a low-pressure system approaching from the southwest will generate moderate northeasterly winds throughout Louisiana, helping to disperse pollutants and yielding Good AQI levels statewide.
