Boston, Massachusetts – A multi-day winter storm deposited widespread heavy snow across the Boston region, with final totals now confirmed by the National Weather Service.
According to NWS Boston, snowfall reports collected over a 48-hour period from Sunday through early Tuesday show most of eastern Massachusetts received 12 to 18 inches of snow, with higher totals concentrated inland. Portions of the region recorded 20 to 24 inches, while a few isolated locations reported storm totals reaching 25 to 27 inches.
The finalized snowfall analysis map, released Tuesday afternoon, reflects a combination of official observations and public reports submitted throughout the event. Heavier accumulations were observed near and along Interstate 93, Interstate 95, Route 128, and sections of Interstate 495, where prolonged snowfall and steady accumulation occurred.
Lower totals, generally ranging from 10 to 14 inches, were reported closer to the immediate coastline and Cape Cod, where marine influence limited accumulation during portions of the storm.
NWS officials noted that not every individual snowfall report appears directly on the map due to the large volume of data received. However, each submission contributed to the overall analysis and helped refine the final snowfall distribution.
The storm’s extended duration — rather than short bursts of extreme snowfall — played a key role in producing high cumulative totals across the region. Snow fell steadily over multiple periods, creating prolonged impacts for road crews and public works departments.
For commuters, students, and young workers, lingering snowpack and cleanup efforts continued to affect travel along major corridors and secondary roadways even after snowfall ended.
The National Weather Service thanked the public for submitting observations, emphasizing their importance in post-storm verification and future forecasting accuracy.
