As an Arctic front pushes south and eastward, a weak coastal storm will quickly develop just off the Northeast coast, leading to an enhancement of snowfall totals just inland from the I-95 corridor.

On Monday, we’ll see the cold front begin to bring snow to western Pennsylvania and New York during the afternoon. Then overnight, the snow will become more widespread as it overspreads to the east. Snow is forecast Monday night for most of New York, Pennsylvania, and West Virginia while a few snow showers sneak into northern New England.




It’s not until Tuesday when we’ll begin to see our coastal low form just south and east of the I-95 corridor. During the morning hours, the front will slowly slide to the east, keeping the snow around in central New York southward through eastern Pennsylvania, western Maryland, and down the Appalachian chain. Then in the afternoon, snow showers will overspread again into Update New York and northern New England while a steady, widespread snow develops across inland Southern New England. The snow will move closer to the coast overnight, with a line of snow spreading from the Raleigh area in North Carolinas up I-95 through Richmond, Washington, D.C., Philadelphia, New York, and Boston. Thankfully, this is happening overnight because the whole corridor will be experiencing snow Tuesday night. The heaviest intensity in snowfall will be across inland Southern New England due to the enhancement of the coastal low and mesoscale banding features. It will be the opposite at the Southern New England coast where there may be mixing issues, especially on the Cape, in southeastern Massachusetts, and in southern Rhode Island. It’s these areas were up to half a foot of snow is possible. In the other locations, only up to an inch of two is expected in the I-95 corridor, and temperatures will be marginal but cold enough for snow.




By Wednesday morning, we think the snow will be east of the I-95 corridor in the Mid-Atlantic, so Washington, D.C. and Philadelphia should dry out by the time the sun rises, but snow may dwindle at the coast. To the north and east, snow will persist from New York City up through Boston before all of the snow clears out of the Northeast by the early to mid-afternoon. Because of the timing of when this snow ends, school delays are possible in the areas of these major Northeast cities. We also wouldn’t be surprised if many Southern New England schools close for the day Wednesday.

Here’s our snowfall forecast:
