Overview
- Snow moves in from south to north Sunday morning, with first flakes in Boston and Worcester likely between late morning and early afternoon before expanding across southern New England by midday.
- The worst conditions are expected Sunday from about 8 p.m. to midnight, when heavy bands could drop 1–2 inches per hour with very low visibility and dangerous travel.
- A coastal front near the I-95 corridor and onshore warmth are forecast to introduce rain or ice along the South Coast, Cape and Islands, reducing totals there and making snow wetter in far eastern areas.
- Forecasters expect mainly light, powdery snow inland with blowing and drifting, and they do not anticipate significant coastal flooding while power outages are projected to be isolated.
- Snow becomes more variable on Monday and tapers by Monday night into early Tuesday, with 12–20 inches possible for most away from extreme southeastern Massachusetts, some track and banding uncertainty remaining, and a deep freeze to follow.
