Thursday, an upper-level trough of low pressure west of Louisiana will promote atmospheric mixing. In addition, partly cloudy skies and isolated to scattered thunderstorms will limit ozone development, while periods of moderate southwesterly winds will aid dispersion in the southeastern corner of the state. Therefore, AQI levels will be Good to high-Good. Friday, areas of morning fog will aid particle production. In addition, lighter winds statewide will hinder dispersion. However, as the upper-level trough passes over the state, mixing will continue to be aided, while isolated to scattered thunderstorms will limit ozone production. Thus, AQI levels will remain Good to high-Good. Saturday, as an upper-level ridge of high pressure moves into the state, mixing will decrease. Furthermore, warmer temperatures will aid ozone formation, while periods of light westerly to southwesterly surface winds will inhibit dispersion. However, low pollutant carryover from the previous days will yield Good to low-Moderate AQI levels statewide.
