Massachusetts – Snowflakes drift lazily through gray morning light as sidewalks crunch underfoot and exhaust plumes hang low. The air feels sharp, hovering near freezing, and visibility fades at times under patchy fog. Winter has arrived with purpose, and it is not finished yet.
Early today, snow develops across the Boston metro area, especially after midday. Accumulation remains limited, but slushy roads are likely during the afternoon commute. Drivers should expect slick conditions on untreated streets, ramps, and neighborhood roads. Conditions improve later as precipitation tapers.
Tonight brings a messy transition. Rain and snow mix with areas of fog, keeping pavement wet. Temperatures settle near freezing, which raises concerns for refreezing in spots. Use caution on bridges and overpasses, where surfaces cool faster.
Midweek offers a brief pause. Wednesday turns partly sunny but stays brisk, with gusty northwest winds and highs near the upper 30s. Wednesday night dips colder, setting up a seasonably chilly Christmas Day. Holiday plans benefit from dry weather, though clouds linger and temperatures remain below 40.
The focus quickly shifts to late Friday. Colder air deepens as another system approaches New England. Snow becomes increasingly likely Friday night into early Saturday. While amounts remain uncertain, even light accumulation could impact post-Christmas travel across eastern Massachusetts.
Travelers using I-93, Route 1, and the Mass Pike should plan extra time Friday evening. Snow-covered roads and reduced visibility may develop quickly after sunset. Black ice becomes a concern overnight as temperatures drop into the teens.
This on-and-off winter pattern is typical for late December. With colder nights ahead, untreated moisture will not disappear easily.
Stay weather-aware and prepare vehicles for winter driving conditions.
