REMARKS:Thursday, surface high pressure will build over Louisiana, generating light winds and reducing pollutant dispersion. However, dry air will limit particle production, and regional pollutant carryover from previous days will be low. These conditions will yield Good AQI levels statewide. Friday and Saturday, moderate northerly winds will help to disperse pollutants. In addition, cooler temperatures will inhibit ozone formation, leading to Good AQI levels across Louisiana on both days.
