Baltimore, Maryland – A colder, more unsettled pattern is developing across Maryland as December begins, prompting a December Snow Alert while winter in Baltimore grows more active. While it’s too early to determine exactly how many inches of snow could fall, one thing is certain: Maryland is positioned for an above-average amount as colder air interacts with increasing storm opportunities.
According to the Climate Prediction Center, below-normal temperatures and near- to above-normal precipitation are favored across the Mid-Atlantic through December. According to the National Weather Service in Sterling, this setup supports several early-winter storm windows, including coastal lows and inland systems capable of bringing accumulating snow to the northern half of the state, with mixed precipitation more likely near the Bay.
According to MDOT SHA, travel hazards may increase along I-95, I-70, the Baltimore Beltway, and Route 29 as colder mornings promote black ice and quick bursts of heavier snow slow commuters. Reduced visibility and slick bridges may complicate travel before sunrise. Drivers should charge phones, carry winter kits, and allow extra time on untreated roads.
Holiday events across Baltimore, the suburbs, and central Maryland may encounter delays if clippers or coastal storms track close enough to deepen snowfall. Residents should dress in layers, protect exposed pipes, and prepare for brief outages if wetter snow or gusty winds bring down limbs and lines.
While specific snowfall totals remain uncertain this early, long-range trends continue to point toward a colder, storm-supportive pattern — raising confidence that Maryland is headed for a snowy December and improving the chance of a White Christmas for northern and western communities.Maine Weather: December Set to See Snow Alerts as Winter in Portland Strengthens
