Area dispatchers and police in the Eastern Panhandle of West Virginia said poor road conditions led to several minor traffic accidents.
A tractor-trailer slid off Interstate 81 in Berkeley County near exit 12 Saturday night and crews worked Sunday to move the truck out of the snowy conditions, police said.
Washington County Highway Department supervisor Ed Plank said Sunday morning about 40 trucks were operating to clear snow from the roads. Contract drivers also were working, he said.
"We're trying to get everything off for tonight because we're sure the temperatures are going to drop, and we'll have some icing," Plank said.
The forecast for this week is for partly cloudy days with temperatures in the 40s and 50s, said John Darnley with the National Weather Service. Rain could arrive by Thursday night or Friday morning, with snow in higher elevations, he said.
"With the amount of snow on the ground, the water equivalent is pretty high. It all has to go somewhere, and it's gonna go in the rivers," Darnley said.
According to the National Weather Service, the Potomac River was about 7 feet lower than its flood-stage level of 10 feet in Martinsburg, and about 5 feet lower than its flood-stage level of 8 feet in Sharpsburg.
For James Hines II, a Greencastle, Pa., second-grader, a forecast calling for higher temperatures will bring no relief. He said Sunday he was hoping for a snow day.
James hopped and tumbled over a new snowboard he got for Christmas, while other children at Fairgrounds Park got this year's first use out of sleds, snow tubes and discs.
Some adults said they enjoyed a chance to play in the snow.
Scott Sears, the father of a 3-year-old girl and 5-year-old boy, plunged down a hill headfirst on his back, then laid on the ground looking at the sky as he made snow angels.
After the plummet, Sears, 31, said he and his wife and children were enjoying the day outside.
"It's been awhile. It makes you feel like you're 10, 20 years younger, and then a little while later, your body tells you that you were wrong," Sears said.
