Forecast Discussion: A rebound in fine particle concentrations to the lower Moderate range is expected Thursday as high pressure moves through the region. A cold front will usher in stiff winds on Friday, very quickly cleaning the air and bringing Good air quality to Maryland. High pressure again moves in on Saturday, but the arctic airmass associated with it is not expected to degrade significantly by the time it arrives in the region, therefore leading to Good air quality. - MDE
