According to ABC News, more than 100 million Americans are under winter alerts Friday as a storm hits the Mid-Atlantic and Northeast and another brutal surge of Arctic air pushes into the South.

Snow is currently falling from Indiana to Delaware causing dangerous commutes in Cincinnati, Pittsburgh, Washington, D.C., Baltimore and Philadelphia. New York City may get 1 to 2 inches of snow — the second day this week with more than 1 inch of snow following New York City’s snow drought of more than 700 days.

Baltimore City Public Schools and Pittsburgh’s public schools also closed their doors on Friday. In Nashville, schools have been shut down the entire week in the wake of the snowfall that wreaked havoc on roads.

Meanwhile, a reinforcing shot of Arctic air is expected to settle in on Friday and should stick around through the weekend across the Midwest and Great Lakes. All that cold air should help generate the intense lake effect snow bands that have been blanketing numerous locations along the lakes this week.

The highest snow report in the last 48 hours is from Copenhagen, New York, where residents saw a whopping 50 inches of heavy lake effect snow.
