Broad troughing over the eastern US will result in temperatures at or slightly below seasonal norms for the weekend. This along with a clean easterly flow will help to keep locations in the threshold Good to low Moderate AQI range despite plentiful sunshine. Winds shift southerly Monday out ahead of an approaching low pressure system. Low Moderate conditions will likely turn more widespread, particularly along and north of the urban corridor. By Tuesday, a cutoff low will impact the area bringing widespread cloud coverage and intermittent precipitation. Ozone levels will be held comfortably in the Good AQI range, persisting into Wednesday. For the latest air quality information, please visit our website here. -MDE
