East Coast Winter Storm: Snow For Northeast; Blizzard Conditions Possible in New England

Mid-Atlantic States (NYC south)

• Timing: Light to moderate snow from the Great Lakes and Ohio Valley into the central Appalachians and Mid-Atlantic states during the day, ending Tuesday night. For the I-95 corridor the snow may mix with rain, at times. As the merger occurs and the coastal low strengthens, some snow and wind will spread through the Delmarva Peninsula, New Jersey, the New York City area including Long Island Tuesday afternoon and evening. Snow ends in these areas Wednesday morning.
• Snow totals: 1-3" in most areas from the New York City metro south into Virginia, West Virginia and the mountains of North Carolina. A few totals up to 6 inches are possible in the central Appalachians, and along the eastern Delmarva Peninsula.
• Wind impact: Gusts over 40 mph possible along the Delmarva Peninsula and Jersey Shore Tuesday afternoon and Tuesday night.

  New England

  • Timing: Snow moves into southern New England Tuesday night and intensifies in eastern New England Wednesday. Snow ends in southeast New England Wednesday night and in eastern Maine by Thursday morning.
  • Snow totals: Heaviest totals likely across Downeast Maine, Cape Cod, Martha's Vineyard and Nantucket with over 6 inches of snow. Depending on the final track of the storm, some or both of these areas may pick up over a foot. Lighter accumulations, on the order of a couple of inches to the west, including most of the Boston metro.
  • Wind impact: Gusts over 60 mph likely over Cape Cod, Martha's Vineyard and Nantucket Island Wednesday morning, tapering off during the afternoon. Some gusts over 60 mph also possible in parts of Downeast Maine Wednesday and Wednesday evening. Expect power outages and tree limbs downed. A few gusts over 50 mph are possible as far west as Boston Wednesday.
  • Coastal flood threat: Minor to moderate coastal flooding for Wed. morning high tide along north-facing shoreline of Cape Cod and Nantucket. Beach erosion is likely on ocean side of Cape Cod and east shore of Nantucket, according to the National Weather Service in Taunton, Mass.
  • Canadian impacts: Regardless of the exact track, a major blizzard appears likely across portions of the Canadian provinces of Nova Scotia, New Brunswick, and Prince Edward Island, potentially expanding into Newfoundland later in the day. Depending on the storm track, some areas may change over to rain after a burst of heavy snow.
  • Offshore impacts: The National Weather Service has issued hurricane force wind warnings for the open ocean off the New England coast. This does not affect areas near shore, but well offshore sustained winds could reach 90 to 95 mph and seas could reach 50 feet with some individual waves even higher than that. While not as extreme, gale to storm force winds and rough seas are still expected closer to the Northeast coast.
