By 8 a.m. ET, the roads in Roanoke, Va., were coated. And in the early afternoon, a wet, driving snow was falling rapidly in D.C. and West Virginia.
It was the start of an anticipated 36 hours of snow that will blanket the East Coast, burying the nation's capital and potentially hobbling travel throughout the region.
The storm was predicted to be potent and shows no sign of falling short of expectations. The Associated Press summed the situation up: "One in seven Americans will get at least half a foot of snow outside their homes when this weekend's big storm has finished delivering blizzards, gale-force winds, white-out conditions and flooding to much of the Eastern United States."
The National Weather Service is anticipating snowfall between 1 and 2 feet from eastern Kentucky to New Jersey and morethan 2 feet across portions of the Mid-Atlantic, including Washington, D.C., and Baltimore. Forecasts call for 12 to 18 inches in Philadelphia and up to a foot in New York City. The National Weather Service reported late Friday that snow drifts had reached more than 5 feet in parts of West Virginia.
NASA's image of the day Thursday showed the storm on Wednesday, when it was still building over the central U.S. The storm system started in the Pacific ocean, tracked across the U.S. to the Gulf Coast and then moved toward the Mid-Atlantic region.

Approximately 50 million people are in the path of the storm, the AP reports. Several states and cities have battened down ahead of the storm. State offices are closed across Tennessee, the AP reports, and that state, Delaware Georgia, Maryland, North Carolina, New Jersey, Pennsylvania, Virginia and West Virginia have all declared a state of emergency.
Those traveling by plane might be in for a struggle, too: Some flights through Nashville, Philadelphia and Newark, N.J., have been canceled, and by late Friday FlightAware.com's "Misery Map" showed an total shutdown in Charlotte and Washington.
In the world of sports, two NBA games, an NHL game, numerous college basketball games and the NASCAR Hall of Fame induction ceremony were all postponed, the AP reports.
Multiple people already have died in car accidents on icy roads, and North Carolina's state troopers told ABC that they'd responded to more than 1,200 wrecks by the early evening. But Weather Prediction Center meteorologist Paul Kocin tells the AP that he hopes the timing of the storm — hitting over the weekend — as well as the advance warning will help minimize the number of deaths.

Meteorologists and government officials across the East Coast are warning residents to stay home, stay warm and stay off the roads. But D.C. residents who dare step out into the post-blizzard world can enjoy one activity — legally — for the first time in decades.
Sledding down Capitol Hill had been banned for years. But in the omnibus budget deal that Congress passed last year, the legislators indicated that from now on, they're going to let it slide.
