Boston, Massachusetts – A significant winter storm is increasingly likely to impact southern New England late this weekend, with heavy snowfall expected to create dangerous travel conditions from Sunday night into Monday, especially across interior Massachusetts and northern Connecticut.
According to the National Weather Service in Boston, snow is expected to develop Sunday morning or early afternoon, with the heaviest snowfall rates arriving Sunday evening and continuing overnight into early Monday. Forecast confidence is high that much of the region will see impactful snowfall, with medium confidence in widespread totals of one foot or more across central and western Massachusetts.
The most likely snowfall totals range from 12 to 18 inches from the Berkshires through the Worcester Hills and into portions of northern Rhode Island and interior Connecticut. The Boston metro area, including Cambridge, Quincy, and Brookline, is also within the zone for potentially heavy snow, though forecasters note lower confidence near the immediate south coast due to the risk of mixed precipitation. Cape Cod and the Islands may see reduced totals if rain or sleet mixes in.
Travel impacts are expected to be highest Sunday night into Monday morning, when snowfall rates could overwhelm road treatment efforts. Motorists should plan to avoid unnecessary travel, especially during overnight hours, and prepare for snow-covered roads and reduced visibility.
Snow is expected to taper Monday, but lingering impacts and slow travel conditions could persist. Forecast details may continue to be refined over the next one to two days as the storm track becomes clearer.
