Forecast Discussion: On Friday, a stationary front in the region introduces some uncertainty with cloud cover and timing of rain showers. With light, westerly surface winds, hot and humid conditions, and generally partly cloudy skies until rain arrives late in the day, low Moderate AQI is expected for the metro areas. On Saturday, the front pushes further south and high pressure begins to build in from the northeast. Winds shift to the east giving way to Good AQI for most locations. On Sunday, similar conditions with high pressure centered to the northeast for another day leading to Good air quality. - MDE
