Tuesday, September 29: A lingering trough of low pressure aloft will aid atmospheric mixing, while partly cloudy skies hinder ozone formation. In addition, light northwesterly winds will carry a clean air mass across the Mid-Atlantic. Therefore, Good AQI levels are anticipated for ozone and PM2.5. Wednesday, as surface high pressure moves into the state, light and variable winds will inhibit dispersion, and warmer temperatures will aid ozone development. However, pollutant carryover from the prior days will be low. Thus, AQI levels are anticipated to be high-Good for ozone and PM2.5. Thursday, a building ridge of high pressure aloft will limit atmospheric mixing. In addition, southwesterly winds will carry regional pollutants into Delaware, while partly sunny skies and highs in the mid-80s support ozone formation.
