Forecast Discussion: It will be warm and humid to close out the last weekend of summer. Increasing atmospheric humidity and light winds through the afternoon will allow particles to rise into the Moderate range. Summer-like temperatures will increase ozone concentrations as well, but scattered clouds and less intense autumn sunlight will limit the daily average to the upper Good range. **Extended Forecast: A cold front will move through Delaware overnight Sunday into Monday. A cool and dry air mass will filter into the Mid-Atlantic region behind the front and remain for the duration of the week. Below average temperatures, low humidity, and northerly flow will keep air quality in the Good range for Monday and Tuesday. -Huff
