      NOAA: Air quality to drop across region

      ROSEBURG, Ore. -- There goes that air quality again.

      The National Weather Service has issued an air stagnation advisory for our area.

      Basically, inversions over the valley are expected to cause a drop in air quality, and it's expected to last through the weekend.

      With air stagnation, there is an increased chance of pollutants being trapped.
