Maryland – A gray stillness covers Baltimore this morning as light winds ripple across the Inner Harbor, setting the stage for a subtle but meaningful winter shift. Pavement remains damp, but colder air circling behind a stalled boundary may create fast-changing conditions heading into the weekend. Even brief flurries could catch evening commuters off guard as temperatures slide downward.

According to the National Weather Service, a slight winter storm threat continues for central Maryland Saturday night into early Sunday. Forecast confidence remains low on exact placement, yet meteorologists highlight the risk of a narrow snow band capable of producing 1–3 inches if the colder air arrives quickly enough. The agency notes that travel disruptions are possible, especially in neighborhoods north and west of the city where temperatures dip close to 32°F during the transition.

Latest models show a rain–snow changeover late Saturday, then a window of steadier snow before daybreak Sunday. A subtle shift in track could decide whether the metro sees light coatings or more impactful slushy accumulation. Plan extra time on I-95, the BW Parkway, and local overpasses, where early-morning black ice may form as winds become northwest at 5 mph and temperatures fall into the upper 20s.

Sunday turns colder but brighter, with highs near 32°F and wind chills dropping quickly toward the teens. Across the Chesapeake Bay and tidal Potomac, gale conditions are possible late Sunday into Monday, adding a sharp winter edge to the region’s second week of December.

Keep coats, gloves, and windshield scrapers ready—after all, early-season systems can shift fast, and even minor snow can disrupt weekend plans.
