A major winter storm is still rolling across the U.S., beginning with blizzard conditions in the plains last night, and dropping snow onto mid-Atlantic states this morning.

The National Weather Service warned some places could see their heaviest snowfall in a decade.

It's having a major impact on travel, while students from Indiana to Maryland are enjoying a snow day.

In Washington, D.C. this morning, the competition was fierce.

You just saw me now that guy in the face, right?

As huge crowds gathered at Meridian Hill Park for a timeless snow day tradition, the snowball fight.

The nation's capital received its first major snow of the winter, as a polar vortex chills a large part of the country.

Baltimore was blanketed in white this morning as Maryland canceled classes and closed government offices.

Temperatures are expected to plunge

from the northeast as far south as Georgia and Florida. In Woodbridge, Virginia, residents

like James Rastatter were snowed in.

A four-wheel drive broke down, so I'm using a two-wheel drive with change. And hopefully

I can get out today, and hopefully the plow comes tomorrow and gets us out.

The storm kicked off in the central states on Sunday before moving eastward.

Biting winds created blizzard conditions in Kansas yesterday, covering the roads with snow and ice.

10 inches of snow has already fallen there. More than 14 inches are expected

for Kansas and parts of northern Missouri. The storm also complicated air travel, causing more

than 1,300 flights to be canceled and 8,500 to be delayed. As the storm spread to the east,

dozens of semi-trucks were backed up in downtown Cincinnati.

A cluster of trucks stuck in the snow on a ramp led to a nearly seven-hour delay last night.

Hundreds of thousands were without power across Kentucky, Indiana, Virginia, West Virginia, Illinois, and Missouri.

Couldn't be worse.
