Boston, Massachusetts – A colder, storm-ready pattern is taking hold across Massachusetts as December begins, triggering a December Snow Alert while winter in Boston turns more unsettled. While it’s too early to determine exactly how many inches of snow could fall, one thing is certain: Massachusetts is positioned for an above-average amount as colder air teams up with increasing storm chances.
According to the Climate Prediction Center, below-normal temperatures and near- to above-normal precipitation are favored across southern New England through December. According to the National Weather Service in Boston, this setup often supports multiple storm windows, including coastal systems capable of producing accumulating snow inland and mixed precipitation along the shoreline when temperatures hover near freezing.
According to MassDOT, travel hazards are likely to increase along I-90, I-93, Route 128, and the Southeast Expressway. Black ice before sunrise, quick bursts of heavier snow during stronger fronts, and reduced visibility around evening commutes may slow travel across the greater Boston area. Drivers should charge devices, keep emergency kits ready, and allow extra time on untreated roads.
Holiday events—from tree lightings to waterfront gatherings—may face disruptions if clippers or coastal lows track close enough to deepen snowfall across central and eastern Massachusetts. Residents should dress in layers, protect exposed pipes in older buildings, and prepare for brief outages if wetter snow or gusty winds take hold.
Exact storm totals remain uncertain at this early stage, but long-range indicators point toward a colder, more active pattern — raising confidence that Massachusetts is headed for a snowy December and improving the odds of a White Christmas for inland communities.
