Forecast Discussion: Continuing light winds, an inverted atmosphere and a dirtied airmass persist on Tuesday resulting again in upper Moderate air quality for fine particles. Winds will shift to the east, putting the area of highest concentration mainly from the DC metro in to western Maryland. On Wednesday, wind and rain will help disperse pollution, resulting in cleaner, though persisting Moderate air quality for the daily average. Behind a cold front on Christmas morning, Good air quality is expected. - MDE
