A swath of snow will fall on the northern flank of a storm bringing rain and thunderstorms to the Northeast. Snow will stretch from northern New York to central and northern Vermont, New Hampshire and western and central Maine Tuesday night into Wednesday: AccuWeather report

State College, Pa. -- 22 November 2011 -- AccuWeather reports while rain and fog will slow travel for millions in the Central and Eastern part of the nation into Wednesday, it is snow that will cause travel problems in northern New England.

A swath of snow will fall on the northern flank of a storm bringing rain and thunderstorms to the Northeast. Snow will stretch from northern New York to central and northern Vermont, New Hampshire and western and central Maine Tuesday night into Wednesday.

Snow will reach into southern New Brunswick and part of Nova Scotia as well.

Up to half a foot (15 centimeters) of snow will fall in this swath, combined with some rain that will make for slow, slushy, sloppy travel.

Interstates that will be impacted by the snow include I-87, I-89, I-91, I-93 and I-95.

Cites impacted by snow will include Burlington and Montpelier, Vt., Concord, N.H., Portland, Maine and Montreal, Quebec.

It is possible enough snow, poor visibility and low ceilings will occur to impact air travel, especially with connecting commuter flights.

A mixture of rain and snow of some sort will fall along the southern flank of the heavy snow area. Either snow will change to rain, or rain will change to snow before ending. In some cases, both will occur.

What is bad news for travelers is good news for skiers. A fresh, modest layer of natural snow will be on the slopes from part of the Adirondacks of upstate New York to the Green Mountains of Vermont and the White Mountains of New Hampshire.

Temperatures will also permit some snowmaking Wednesday night into Friday morning in New England, prior to a warm-up for the balance of the long holiday weekend.

The same storm causing snow in northern New England will bring rain from Boston to New York City southward to Washington, D.C. and Richmond, Va.

Although travelers would gladly take rain over snow, rain will lead to road and airport delays.

Thunderstorms could add to problems in the I-95 mid-Atlantic region Wednesday.
