Ozone and PM2.5 Air Quality Index (AQI) Forecast
Issued: Friday, July 26, 2024, 2:32 PM
Friday, as upper-level low pressure lingers over Louisiana, an influx of humid and unstable air will produce widespread clouds and scattered thunderstorms, keeping ozone development in check. However, periods of light southerly winds will hinder dispersion and gradually transport a thin plume of Saharan dust across the state. As a result, AQI levels will be low-Moderate. Saturday and Sunday, clouds, rain showers, and thunderstorms will continue to reduce ozone production across Louisiana. In addition, light southerly winds will slowly push the thin plume of Saharan dust to the north of Louisiana, gradually lowering particle concentrations. However, low wind speeds will continue to hinder dispersion. Therefore, AQI levels will be low-Moderate in most cities on Saturday and high-Good in most cities on Sunday.
