Massachusetts Snow Bands Shift Offshore as Rounds Two and Three Target I-95 Corridor Overnight
BOSTON, MASSACHUSETTS — A powerful winter weather system continues to affect Massachusetts and nearby Southern New England, even as the primary snow band begins shifting offshore. Meteorologists say rounds two and three of snow bands are now lining up, supported by lingering frontogenesis, with the most persistent snowfall expected to continue through the I-95 corridor overnight.
Radar imagery and mesoscale analysis show that while the initial burst of heavy snow is weakening near the coast, new organized bands are redeveloping inland, keeping travel conditions hazardous across eastern and central Massachusetts. Forecasters warn that snowfall rates could quickly intensify again in short bursts, particularly near and west of Boston.
Snow Band Evolution and Atmospheric Setup
The latest analysis indicates that frontogenetic forcing at the 700 mb level remains strong enough to regenerate snow bands even after the first wave exits offshore. This process, commonly referred to as FGEN, allows colder air and moisture to converge, sustaining narrow but intense snowfall corridors.
These bands are not expected to be continuous everywhere. Instead, snowfall will occur in waves, with sharp differences in accumulation over short distances. Communities along and just west of Interstate 95 remain especially vulnerable to these repeat snow bands as the system slowly pivots.
Meteorologists emphasize that these secondary bands can produce brief but heavy snowfall, significantly reducing visibility and rapidly covering roadways that may have already been treated earlier in the evening.
Radar Shows Persistent Snow Across Central and Eastern Massachusetts
High-resolution radar from the Boston area highlights several narrow snow streaks stretching from western Massachusetts through Worcester County and into eastern Massachusetts. These bands are oriented southwest to northeast, a classic signature of strong mid-level forcing.
Areas including Springfield, Worcester, and suburbs west of Boston are seeing intermittent moderate to heavy snow, while coastal areas experience periods of lighter snow as bands redevelop inland. Snow intensity is expected to fluctuate overnight, making timing difficult for commuters and emergency planners.
Forecasters caution that even as one band weakens, another may quickly form nearby, leading to prolonged impacts despite breaks in precipitation.
Travel Conditions Along the I-95 Corridor Remain Hazardous
The greatest concern overnight remains travel along the I-95 corridor, where repeated snow bands could lead to rapid accumulation, slick roads, and poor visibility. Secondary highways and untreated roads may become particularly dangerous during heavier bursts.
Drivers are urged to use caution, reduce speeds, and allow extra time for travel. Local officials note that plowing operations may struggle to keep pace when snow bands intensify suddenly, especially during overnight hours.
Air travel delays are also possible at Boston-area airports as snowfall rates fluctuate and runway conditions change.
What to Expect Through the Overnight Hours
Forecast guidance suggests that rounds two and three of snowfall will persist through much of the night before gradually weakening toward early morning. While total snowfall amounts may not increase dramatically everywhere, localized higher totals are likely where snow bands repeatedly pass.
Residents should be prepared for changing conditions, including periods of reduced visibility and drifting snow. Power outages are not widespread at this time, but isolated issues remain possible if snowfall rates briefly become heavy enough to weigh down tree limbs.
As Massachusetts continues to contend with this evolving winter storm, staying weather-aware overnight will be critical, especially for those traveling or working early morning shifts.
