ACCUWEATHER - A storm will drop heavy snow and disrupt travel from parts of the Midwest to a large part of the Northeast by Sunday.
The snowstorm will reach span more than 1,000 miles and affect tens of millions of people.
Thanks to recent Arctic air making roads and sidewalks much colder compared to previous storms, enough snow to shovel and plow is in store from parts of Missouri, Illinois, Indiana, West Virginia, Virginia, Maryland and New Jersey to much of Ohio, Pennsylvania, New York, Massachusetts, Connecticut, Rhode Island, Vermont, New Hampshire and Maine.
Not only will the storm make roads and sidewalks slippery, raising the risk for slip-and-fall incidents and auto accidents, but it is likely to cause many flight delays and cancellations. The visibility will be poor, runways will become snow covered and aircraft will need to be de-iced.
A mixture of snow, sleet and rain will mitigate accumulations across central Missouri and eastward along the Ohio River. However, enough wintry mix will fall to make roads slippery.
Long stretches of along the I-70, I-75, I-80 and I-90 corridors may be snow covered in the Midwest.
A quick change to plain rain is likely from Roanoke, Va., to Washington, D.C., and Baltimore with little or no accumulation to up to an inch or so. Some roads may be slippery.
However, farther to the northeast along the I-95 corridor, the change to rain following snow and/or a wintry mix will take longer, leading to 1 to 3 inches accumulation and more widespread slippery travel.
Snow and a wintry mix are likely to impact play during the Army-Navy Classic Saturday afternoon and evening at Lincoln Financial Field in Philadelphia. This wintry game will occur just less than a week after heavy snow fell during the Eagles-Lions game. Snow buried the field and had players sliding and shoveling snow with their feet during last Sunday's game.
Farther to the north over the Midwest and from western and northern Pennsylvania to northern New England, where the cold air hangs on longer or lingers through the duration of the storm, heavy snow will fall with some communities receiving 6 inches of snow. Roads will be slushy to snow covered over much of the I-80, I-81, I-87, I-88, I-90 and I-95 corridors.
A general swath of 6- to 10-inch snowfall with local amounts near 1 foot is likely to reach from part of northeastern Pennsylvania through the Catskills and Berkshires into southern Vermont, southeastern New Hampshire and southern Maine.
In much of New England, the storm will linger into Sunday with ongoing travel disruptions. While flurries will occur over the central and southern Appalachians and downwind of the Great Lakes over the Midwest, the storm will be over across the Ohio Valley and coastal mid-Atlantic, and travel conditions will improve.
