Labor Day, calm to light west-southwesterly winds will allow pollutants to accumulate. In addition, hot temperatures and periods of sunshine will aid ozone development across northern Louisiana, where AQI levels will be low-Moderate. For the remainder of the state, scattered thunderstorms will promote mixing, yielding Good to high-Good AQI levels. Tuesday, calm to light southerly winds will continue to inhibit dispersion. Furthermore, partly sunny and hot conditions will promote ozone formation in northern Louisiana, where AQI levels will remain low-Moderate. In central and southern Louisiana, another round of scattered thunderstorm activity will aid vertical mixing and limit ozone production, keeping AQI levels Good to high-Good.
