Massachusetts, Rhode Island, and Eastern Connecticut Still Tracking 11–13 Inches of Snow With Additional Overnight Accumulation and Possible Ocean-Effect Burst Monday

UNITED STATES — Snow cleanup efforts across Eastern Southern New England (SNE) are far from complete as the region continues to deal with widespread 11 to 13 inches of snow already on the ground, with more accumulation still expected overnight into Monday before the storm fully winds down.

Latest short-range model guidance and observational trends indicate that while the core of the storm has already delivered most of its snow, the back end and ocean-enhanced component could still add meaningful totals — especially closer to the coast.

Current Snow on the Ground

As of late Sunday evening, snowfall analysis supports:

• Widespread 11–13 inches across much of eastern Massachusetts, Rhode Island, and eastern Connecticut
• Slightly lower totals farther inland
• Higher ratios producing fluffy, easily drifting snow in colder air

Forecasters caution that while these numbers represent what’s already fallen, they do not include all snow yet to come clearly.

Overnight Snow Still Expected

Guidance suggests additional snow overnight, though amounts are uncertain and may vary town by town. A reasonable expectation is:

• 1–3 inches overnight in many areas
• Potentially more if mesoscale bands persist longer than expected

Some estimates suggest shaving a few inches off earlier storm-total forecasts, but not enough to materially change cleanup impacts.

Wildcard: Ocean Effect / Back-End Snow Monday

The biggest remaining uncertainty is Monday’s ocean-enhanced and back-end snowfall.

• Models disagree on how intense or widespread this feature becomes
• Most solutions still produce at least a few additional inches
• If conditions align correctly, another 3–6 inches is possible in localized coastal or near-coastal zones
• Very high snow ratios could allow small amounts of liquid to produce larger snow totals

This phase will likely be a nowcasting situation, meaning snowfall rates and impacts won’t be fully understood until they’re actively occurring.

When Will Final Totals Be Known?

Forecasters stress that final snow totals will not be known until Monday evening, once:

• Overnight snow ends
• Ocean-effect bands fully weaken
• Monday afternoon and evening snow showers taper off

Until then, cleanup planning should assume more snow is coming, not that the event is finished.

Cleanup Challenges Ahead

With cold temperatures locked in:

• Snow removal will remain slow
• Snowpack will be resistant to melting
• Drifting could re-cover cleared roads, especially overnight and early Monday

Residents are urged to pace cleanup efforts and remain patient as plows and crews continue working through lingering snowfall.

Bottom Line

Eastern Southern New England is dealing with a multi-phase snow event, not a single burst. With 11–13 inches already on the ground and more snow still possible overnight and Monday, final totals remain uncertain — and could still climb meaningfully in some areas.
