LIVE: Snow Piling Up in St. Louis, Reaching NYC Area

A snowstorm will continue to spread a swath of snow eastward for more than 1,000 miles from the Midwest to the Northeast through the weekend.

The snowstorm is projected to impact every major city and rural area from St. Louis to Boston and Portland through Saturday night including Chicago, Detroit, Cleveland, Pittsburgh, Philadelphia and New York City.

Due to the track and intensity of the snowstorm, it is likely that driving conditions will become dangerous as roads become snow covered and slippery along the I-70, I-75, I-80, I-81, I-87, I-88, I-90 and I-95 corridors.

Major airports may also experience significant travel delays and cancellations, as poor visibility, snow-covered runways and icy planes may halt safe travel.

The heaviest snowfall, accumulating 12 to 18 inches, will bury much of northern New England, southern Quebec and the Adirondack Mountains of upstate New York.
