The Weather Service said the chance of snow is "near 100 percent." The agency is forecasting 10 to 20 mph winds.
There were no major snow-related car accidents reported Saturday.
A vehicle entering Interstate 81 at Exit 23 near Marlowe, W.Va., on Saturday morning overturned but the driver was not hurt, West Virginia State Police said.
At City Park in Hagerstown, children and adults were sledding on a hill by the Museum of Fine Arts at City Park.
Among them were Sherri Boudreaux of Hagerstown and her children, Lindsey and Nicholas. This was the first year the children were seeing a truly cold winter since they lived until recently in Florida and Southern California, she said.
Lindsey, 6, said instead of riding a sled down the hill she preferred to roll down it. She then demonstrated her technique.
Nicholas preferred to try out different sleds to find the fastest one, Boudreaux said.
Overhearing that, Lindsey said, "This is fastest!" and again rolled down the hill.
Nearby, members of the Larrick family of Hagerstown were having fun.
While Christopher Larrick, 14, described the 25-degree weather as "very cold," his sister, Stephanie, 10, said she did not mind the temperature.
Christopher said he likes to use a disc sled because it spins around and around as he goes down the hill. Stephanie said she prefers her "lucky purple sled" because it is fast and she wins races with it.
Their father, Bill Larrick, looked at them and explained what he likes best about the two-hour sledding experience: "I like it when the kids fall asleep, exhausted."
