Per the Maryland Department of the Environment (MDE): “A narrow ribbon of wildfire smoke from coastal North Carolina will push its way northward into the state overnight Saturday. At this point in time, the plume looks to focus along and east of the I-95 corridor extending across the Bay to the Eastern Shore coast. Areas impacted by this smoke plume will see fairly high fine particulate levels over a several hour period between roughly midnight and noon.
Meanwhile a cold front will begin to track eastward through the state during the afternoon hours. As the front pushes through, any lingering smoke will wash out as conditions turn cleaner. Expect Moderate to potentially high Moderate fine particulate levels along and east of the I-95 corridor for a 24-hour average. The situation will be monitored closely. Winds shift westerly Sunday into early next week behind the front as Canadian high pressure slowly moves overhead. Despite a fair amount of sunshine, ozone and fine particulate levels will remain in check given a clean residual air mass and unseasonably cool temperatures.”
