Forecast Discussion: A slow moving cold front will approach Maryland from the west on Sunday. Clouds and precipitation ahead of this front will overspread western and central portions of the state in the afternoon. In addition, sustained onshore transport will keep clean maritime air flowing into Maryland, for Good air quality across the state. The front will stall over the state on Monday and slowly move eastward on Tuesday. Clouds, rain showers, and thunderstorms associated with the front are likely most of the day Monday, with locally heavy precipitation possible. Tuesday will continue to be wet and overcast for most locations, with the exception of western Maryland. Good air quality will continue both days. - MDE/PSAQFO
