REMARKS:Thursday, a cold front will move through Louisiana, enhancing mixing in the atmosphere and generating strong northerly winds throughout the state. These weather conditions will effectively disperse pollutants and bring a clean air mass into the region, resulting in Good AQI levels. Friday, moderate northeasterly winds will persist behind the departing cold front, dispersing pollutants and keeping AQI levels Good. Saturday, high pressure over the southeastern U.S. will reduce wind speeds throughout Louisiana, inhibiting pollutant dispersion. However, low pollutant carryover from previous days will yield Good to low-Moderate AQI levels statewide.
