Maryland starts the morning with a damp chill as low clouds hang over Baltimore’s harbor and mist clings to windshields. The air feels raw, and the pavement reflects a dull shine—an early sign of the December weather shifts arriving through Tuesday, when a rain-snow mix may briefly complicate travel across the region.
Rain and snow fall early today before transitioning to steadier rain by mid-afternoon. Winds remain light but may gust near 18 mph, pushing cool, damp air through city streets and along I-95. According to the National Weather Service, the next meaningful system arrives Monday night into Tuesday, bringing a second round of mixed precipitation. While accumulations stay minimal, the timing matters for those returning to work and school after the holiday stretch.
Meteorologists now track a narrow window for rain–snow impacts from 2 a.m. until about 4 p.m. Tuesday, with the best chance for wet flakes in the early morning as temperatures sit close to freezing in some northern suburbs. Even minimal snow can reduce visibility quickly on elevated ramps and bridges, so early commuters should stay alert.
To be fair, this system lacks deep cold air, but the warm-to-cold transitions typical of early December can still create slick patches—especially in shaded pockets from Catonsville to Towson. Models hint at a brief possible changeover before rain becomes dominant again through late morning.
By Wednesday, sun returns and temperatures bounce into the lower 40s, offering a calmer break before another disturbance signals a wetter pattern late week. For now, Baltimore residents should prep for quick shifts: wet roads today, a wintry mix Tuesday, and the potential for flash-freeze conditions where standing water lingers after sunset.
