The first major winter storm of the new year barreled into the U.S. mid-Atlantic states on Monday, closing down federal offices and public schools in Washington, D.C., after dumping a foot of snow in parts of the Ohio Valley and Central Plains.

While the snowstorm caused headaches for some from the Midwest to the Mid-Atlantic, it was pure joy for the new pandas at the National Zoo in Washington, D.C.

A massive winter storm poised to unleash a barrage of heavy snow, treacherous ice, rain, and severe thunderstorms across a 1,300-mile swath of the United States will affect an estimated 62 million people starting Saturday afternoon and continuing into Monday.
