AccuWeather meteorologists say the system will ride an Arctic front from Georgia to the Carolinas before strengthening near the East Coast.
While the storm is not expected to be a major one, it may still bring slippery travel and airport delays from Philadelphia to Boston on Sunday, Jan. 18.
The AccuWeather map shows coating‑to‑1‑inch totals stretching from Philadelphia to New York City, with 1 to 3 inches possible from coastal New Jersey through central and eastern Long Island, southeastern Massachusetts, and into downeast Maine.
Some spots, mainly in coastal New England, could see close to a half-foot of accumulation.
Snow is forecast to move north through the mid‑Atlantic during the day Sunday, reaching the southern New England coast later in the afternoon or evening.
The bulk of the accumulation in New England is expected Sunday night, which may lead to airline delays and possible flight cancellations.
AccuWeather Senior Meteorologist Dan Pydynowski said the storm’s track remains key.
“The storm is expected to move quickly up the East Coast Sunday night into early Monday,” Pydynowski said. “Its exact track will determine how far north snow spreads and whether coastal communities see accumulations or just a brief burst of snow.”
Major cities are likely to be brushed rather than buried. AccuWeather expects little to no accumulation in Philadelphia, with New York City likely seeing a coating to 1 inch.
Boston may pick up slightly more if the storm hugs the shoreline. Enough snow may fall to require aircraft deicing from Philadelphia through New York City and Boston on Sunday.
This coastal system follows an earlier clipper from the Midwest, which will drop quick coatings from the southern Appalachians into Pennsylvania, New Jersey, New York, and New England before the main storm arrives.
Interior areas — including the Poconos, Catskills, Berkshires, and northern New England — may see several light rounds of snow through Monday.
After the storm clears, the National Weather Service says dry conditions are expected from Dr. Martin Luther King Jr. Day on Monday, Jan. 19, through Wednesday, Jan. 21.
