Overview
- The first system is producing rain that changes to snow Friday evening in parts of New England, with the NWS warning of heavy, wet accumulations and isolated power outages where totals top 10 inches.
- Central and southern New Hampshire are forecast for roughly 4–8 inches with evening travel impacts, while the Boston area sees lighter totals Friday night and higher amounts north and west of the city.
- Model guidance has nudged the late‑Sunday to Monday coastal low closer to shore, raising the chance of heavier coastal snow, strong winds, and flooding for southeastern Massachusetts and Cape Cod.
- A Winter Storm Watch is posted for the South Coast, Cape, and Islands, with forecasters highlighting potential gusts over 50 mph and coastal flooding risk near the early Monday high tide.
- Farther south, Baltimore’s most likely outcome is 1–3 inches Sunday night into Monday, and south‑central Pennsylvania expects a few inches with wet-to-slushy roads by day and snowier conditions overnight, though amounts remain track‑sensitive.
