Four snowfall maps outline expected Wednesday morning accumulation across Massachusetts, with coastal changeover to rain possible
What forecasters are expecting for Wednesday morning
Another round of wintry weather is expected to arrive in Massachusetts early Wednesday, Feb. 25, 2026, but projected totals are notably lighter than the region’s recent major storm. Multiple forecast maps released Tuesday morning converged on a similar message: light snow develops after midnight and is most likely to impact the morning commute, with a transition to mixed precipitation and rain in lower-elevation and coastal areas as temperatures moderate.
The common timeline across the maps places the steadiest precipitation between roughly daybreak and midday Wednesday, with the heaviest rates most likely during the early-to-mid morning window. The setup is tied to a fast-moving “clipper” system tracking to the north, a pattern that typically favors a relatively brief period of snowfall in southern New England before warmer air intrudes at lower levels.
How much snow the four maps show
Across the four maps, projected accumulation clusters tightly in the low single digits for most of eastern Massachusetts. The consensus range for many communities is a coating to a few inches, with slightly higher totals most often depicted in higher terrain and farther inland locations where colder air is more likely to hold longest.
Most of eastern Massachusetts: generally a coating to 2 inches.
Interior and higher elevations: commonly up to around 3 inches in the higher end scenarios shown.
Lower elevations and the coast: snow may mix with rain and change to rain, limiting totals compared with inland areas.
Forecast maps for Wednesday morning show light accumulation for most locations, with higher terrain more likely to reach the upper end of predicted totals.
Why totals can vary street to street
While the maps show broad agreement on a light event, small shifts in surface temperature and the timing of the changeover can produce meaningful differences over short distances—especially near the immediate coastline, along major river valleys, and in areas that typically run warmer. A faster change to rain would suppress snowfall totals; a slower changeover would extend the period of accumulating snow and increase totals, particularly north and west of Boston and in elevated areas.
With the event expected to occur during the morning commute, even modest accumulation can create localized slick travel—especially where untreated surfaces remain snow-covered or where earlier snowbanks and narrowed lanes constrain traffic. Conditions are expected to improve as precipitation becomes lighter and, in lower elevations, transitions away from all snow.
What to watch for in updates
Key indicators for any shift in expected impacts include the exact start time of steadier snowfall overnight, whether the heaviest band sets up farther south or north, and the timing of mixing and changeover along the coast. Forecasters typically refine these details as higher-resolution guidance and overnight observations become available.
