Snowstorm from North Carolina to Maine

Sooner or later during Thursday, folks living in part of New England and the mid-Atlantic will need to do this. (Craig Veltri/Phot
Tens of millions of people from western North Carolina to Maine and New Brunswick will have snow falling on their neighborhood sometime from Wednesday evening into Thursday.

The same storm that brought New Mexico snow Monday will deliver accumulating snow to millions of people within this swath from the southern Appalachians to part of the Maritimes.

As we mentioned earlier this week, this will be a scenario of rain changing to snow for a large part of the Northeast.

The fast-moving storm will spare the I-95 corridor of the mid-Atlantic the worst of the snow, but a heavy band of snow will fall in part of the I-81 corridor in Virginia, I-84 in Pennsylvania, New York and southern New England and part of I-95 in New England.

Locally heavy snow will also fall on the West Virginia mountains, eastern Kentucky and northeastern Tennessee.

The storm will put down enough snow to shovel and plow in these areas. However, since the ground is warm from previous days and weeks, the greatest accumulation will be on non-paved surfaces such as cars, lawns, roofs and trees.

As air temperatures fall with the snow, road surface temperatures will cool allowing a slushy, slippery accumulation.

Even in the I-95 zone from Washington, D.C., to New York City to Providence, R.I., where the change to snow will be delayed, slippery spots and/or low visibility from snow can slow travel for a time Thursday.

From Scranton, Pa., and Hartford, Conn., to Boston and Houlton, Maine, several inches of snow is in store with a real slushy mess.

The bulk of the snow will be hitting the interior mid-Atlantic during the late Wednesday night/Thursday early morning hours.

In New England, most of the snow will fall Thursday morning and midday.

The snowstorm will finish up Thursday midday and afternoon over New Brunswick and the Gulf of St. Lawrence region.

Where the snow quits early enough Thursday in the mid-Atlantic and part of New England, northwest winds will work to melt the snow and dry the roads. However, areas that remain wet and that are left untreated will become icy Thursday evening.

In addition to travel delays on roadways and at airports, school delays and closings are possible. Some parents may have to make alternate plans for daycare.

On a lighter note, many area skiers have been waiting from a decent fresh dose of natural snow to hit the slopes.

In addition, enough chilly air will follow the storm over the mountains to allow resorts to add to their base of snow for a few days.

In parts of western and northern New York state that miss out on snow from the storm, lake-effect snow will bring some of the white stuff to traditional areas late in the week.
