Meteorologists continue to closely track a potent nor’easter for Sunday, and it appears that the best chance for significant snow will be across Cape Cod, Nantucket, and Martha’s Vineyard. Forecasters caution that there’s still a large amount of uncertainty in the track of the storm, resulting in a wide range of possible impacts. The nor’easter will likely rapidly strengthen into a bomb cyclone. The National Weather Service’s Boston office says it’s “maintaining a close watch” on the potential coastal storm late this weekend. “Tracks range from a hit to a full miss with some in between solutions showing a ‘graze’ hit to the Cape/Islands in regards to impacts,” NWS Boston added.
