The highest AQ index in Louisiana (as of 17:00 CDT) is currently the New Orleans area. Particle Pollution (PM2.5) is measuring at 66 (Moderate). This means air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Over the next few days, the highest Particle Pollution (PM2.5) will be in the Shreveport area. It is forecasted to be Moderate, meaning air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Tuesday, an upper-level ridge of high pressure will hinder atmospheric mixing over the Bayou State. In addition, light west-southwesterly winds will limit dispersion. Furthermore, these winds will gradually transport regional pollutants into Louisiana. As a result, AQI levels will range from high-Good to low-Moderate. Wednesday, isolated thunderstorms will develop across the northern portion of the state, enhancing mixing and reducing ozone formation slightly. Farther south, mostly sunny and hot conditions will continue to support ozone formation. In addition, light westerly winds will limit dispersion and gradually carry thin Saharan dust into Louisiana, increasing particle levels. Therefore, AQI levels will be low- to mid-Moderate statewide. Thursday, widely scattered showers and thunderstorms will enhance atmospheric mixing and reduce ozone formation in some locations, while hot and sunny conditions continue to support ozone formation in locations that remain dry. Furthermore, light westerly winds will continue to carry thin Saharan dust across the state. These conditions will lead to a continuation of low- to mid-Moderate AQI levels.
