Forecast Discussion: High pressure on Saturday will promote clear skies and light winds which will combine to take ozone into Moderate AQI conditions, mainly for areas along and south of I-95. On Sunday high pressure is still in control but cooler, drier and cleaner air on east winds will lead to Good air quality. A strong but slow moving system across the central United States will lead to copious rain and clouds around Maryland on Monday and Good air quality. - MDE
