As one winter storm winds down over the Midwest and Great Lakes region, forecasters warn that a new system — a potential nor’easter — could unleash “widespread and impactful snow and ice” across the Mid-Atlantic and the Northeast by Tuesday.
Although the timing, track and strength of the storm remain uncertain, Andrew Orrison, a meteorologist at the Weather Prediction Center, said the threat for significant accumulations across much of the interior Northeast on Tuesday was rising.
“For areas of Pennsylvania and New York State, up through the rest of New England, that’s where the heaviest and most impactful winter weather will be,” he said. “We are expecting a swath of six to 12 inches of snow from parts of the Poconos and the Catskills and up through Vermont, New Hampshire, western Massachusetts and a good chunk of Maine as well.”
While the highest totals are expected west of the I-95 corridor, Mr. Orrison said that major metropolitan areas may still see some snow accumulating.
“In New York City and up into Boston, those areas could see at least a couple of inches potentially,” he said. “But the storm is still one to two days out, so the details of that could change a little bit.”
Forecasters expect the storm to develop over the Gulf Coast states by Monday afternoon before tracking up the Eastern Seaboard Monday night into Tuesday.
“Some lingering snow is possible for eastern New England on Tuesday night,” Mr. Orrison said. “But it should taper off by early Wednesday morning, when the storm should be pretty much all gone.”
Before its arrival in the Northeast, the storm is expected to bring winter weather to parts of the Midwest and the Mid-Atlantic, Mr. Orrison said.
At least two inches of snow were expected from central Kansas through the Ohio Valley, including Illinois, Indiana, Missouri and Ohio, with isolated areas receiving four inches or more.
“There will be icing concerns as well, farther south in parts of the central Appalachians,” he said. “And areas a little bit farther south of the Ohio Valley, in the mid-South area, will have some concerns for a little bit of freezing rain on Monday.”
The Weather Prediction Center has identified portions of eastern West Virginia, western Virginia and northwestern North Carolina as having the potential for 0.1 inches of ice from 7 a.m. Monday to 7 a.m. Wednesday.
In the higher elevations of the Blue Ridge Mountains in North Carolina, ice accumulations could approach a quarter of an inch in some spots.
