Overview
- Low pressure is expected to develop near the Carolinas Saturday and make its closest pass to New England late Sunday into early Monday.
- Major models diverge on the track, with European guidance closer to the coast and U.S./Canadian runs farther offshore, so small shifts could sharply change local outcomes.
- Eastern and southeastern New England have the highest odds for impactful snow, with the best chance for plowable totals on Cape Cod, the Islands and southeast Massachusetts.
- Coastal winds are the most confident hazard, with gusts potentially topping 60 mph on Cape Cod and around 50 mph along other shores, raising risks of coastal flooding and erosion during high tides.
- An entrenched Arctic air mass continues to drive dangerous wind chills and lake‑effect snow in the Great Lakes, while low‑probability flurries are being flagged for parts of Florida as the pattern evolves.
