Forecast Discussion: A cold front moves through Friday morning and lingering rain shower activity persists through mid afternoon, but much cooler and drier air moves in to the region on strong northwest winds resulting in Good air quality. Light rain shower activity is possible again Saturday morning for areas east and north of Baltimore but Good air quality continues with persisting stiff northwest winds and cooler, drier air in place. Winds lighten on Sunday and abundant sunshine will increase ozone levels, but with generally clean air in place, Good air quality will continue. - MDE
