Maryland wakes to a cold harbor breeze and steel-gray skies over Baltimore. Pavement feels dry for now, but the air carries that damp December edge. Winter is lining up another transition, and timing will matter for commuters and travelers.
According to the National Weather Service, temperatures start near 31 degrees early, with clouds increasing through the morning. Roads remain mostly dry, but bridges and shaded areas may stay slick early. Drivers should use caution on I-95, I-83, and the Baltimore Beltway during the morning commute.
Conditions improve briefly this afternoon, with highs climbing into the upper 40s. That calm window closes Thursday afternoon, when rain chances increase. Showers become widespread Thursday night, soaking roads and lowering visibility across the metro area.
By Friday morning, rain lingers, and winds pick up. Gusts may reach near 30 mph, especially near the harbor and exposed roadways. Travel could slow during peak hours as wet pavement and breezy conditions combine. Plan extra time if heading toward BWI Airport or traveling south toward Washington, D.C.
Colder air arrives behind the rain Friday afternoon and evening. Temperatures fall toward the upper 20s by nightfall. Any leftover moisture may refreeze, creating black ice into early Saturday. Ramps, overpasses, and untreated side streets are most vulnerable.
This warm-to-cold swing is a classic early winter signal. While snow is not expected in Baltimore through the weekend, models hint at a more active winter pattern developing regionally. With heavy snow impacting parts of the Midwest, weather systems remain energetic heading into Christmas week.
Saturday turns cooler but brighter. Sunday moderates slightly, though mornings stay cold for travelers returning home.
