A new area of low pressure will form off the Southeast coast of the United States on Friday night. Then it will move northeast up the coast, leading to the first snow event for portions of the Mid-Atlantic and Northeast. This will be  quick-moving low pressure so snow totals won’t be as high as they could have been, due to the forward speed of this storm.

Snow will begin to break out Friday afternoon across much of Virginia, southern Maryland, and the DelMarVa. Then into the overnight hours, the snow will persist for these same areas as well as traveling into southern New Jersey and Washington, D.C..

The main event will occur on Saturday, with snow falling for the major I-95 corridor cities. In the Mid-Atlantic, snow will fall for much of the day and then will taper off during the evening hours as the low pressure pulls to the north east direction. Snowfall accumulations will be between one to three inches for most locations around and west of I-95. To the east of the highway, there will be pockets of snowfall totals in excess of three inches.

Further north into the Northeast, snow will begin in the morning for southeastern Pennsylvania, southern New York, Long Island, Connecticut, and Rhode Island. As the day progresses, the snow will work northward into the rest of New England during the afternoon and evening. Then overnight, there will be light snow showers in southern New England and still a widespread, light snow for much of northern New England. It will also be a bit heavier in Maine. As you wake up on Sunday, a light band of snow is possible along the east coast of New England, but all of the precipitation should clear out by noon Sunday.

Now in Cape Cod and the Massachusetts islands, there will be a mix at the onset of the precipitation, but then it will turn into a rain, possibly along the southeastern Massachusetts coast too. Therefore, we aren’t expecting any snowfall accumulations for these locations because of the warmer air.

For the rest of New England, many locations will receive between three and six inches of snow. In Vermont down through the Berkshire Mountains, snowfall will be lighter at one to three inches. That line of one to three inches will also extend into the lower-Hudson Valley of New York. In portions of eastern Maine, higher snowfall rates are forecast, so we anticipate six to ten of snowfall.

Thankfully, winds will be light with this event so power outages aren’t expected, although the heavy, wet snow may take down some branches. Temperatures will also be at or just below freezing, so most roads will be clear if treated.
