Early Week Storm Could Slam the Northeast with Snow and Rain

Forecast models are indicating a coastal low could impact the Northeast from late Sunday through very early Tuesday; bringing the threat of heavy rain, snow and gusty winds along the East Coast.

While there’s still some disagreement in the model runs, here’s the current thinking:

Sunday

rain totals

An upper-level low pressure system will swing into the Deep South and aid in the development of an low along the coast of the Carolinas — near Wilmington, N.C. — on Sunday morning. At this point, the main effect from the system will be some light-to-moderate rain from Raleigh/Durham to Charleston. It could be a bit breezy along the coast as well.

As the day progresses, the low will strengthen and move across the Outer Banks of North Carolina. This will cause rain to spread across may parts of eastern Virginia and the Eastern Shore of Maryland. Rain, at times, could be heavy. Light showers will also be possible form Washington, D.C. to New York City.

As the low develops and pushes moisture north-northwestward, a cold front will also be dropping out of the the Great Lakes region; spilling cold air as far south as the mountains of East Tennessee. While it won’t be a major winter event, some light snow showers are possible form Bristol, Tenn. through western Pennsylvania. Some of the higher elevations in the region could have to deal with slick spots on the roads. Keep that in mind if you’re traveling in the region.

By late evening, on Sunday, the storm will really being to crank up; bringing rain to much of the coastal Northeast. And as the cold air starts to interact with the Atlantic moisture, there could be some light snow for parts of Upstate New York and points further north. That said, large amounts of accumulating snow looks unlikely, but if you’re traveling on the New York Thruway take that into account.

Rainfall totals along the east coast could be in excess of 2.5 inches. This could cause some flooding in urban core of cities like New York and Boston, which would have a severe impact on commutes in the region.

Monday

snow totals

As the low moved up the East Coast, an eventually into the Canadian Maritimes, it could dump snow on parts of New England — especially in parts New Hampshire, Vermont and Maine. According to Meteorologist Stacie Hanes, from the National Weather Service in Gray, Maine, the liquid equivalent of the snow that falls could be up to one inch. The depth of the snow will depend on the depth of the cold air. The colder the air, the higher the snow-to-liquid.

The snow and coastal rain should totally exit the region in the early morning hours of Tuesday.

This is a developing meteorological event and the forecast is subject to change of the next couple of days. WeatherNation meteorologists will be monitoring the latest on the storm and bring you updates on-air and online.
