After a few days of warmer than normal temperatures and melting snow, an overnight storm was expected to drop a light to moderate snowfall.
"It doesn't look like it's going to be a big blockbuster storm, but it's certainly going to be back to winter once again It's not out of the question that it could be mixing with a little bit of sleet or freezing rain as people are heading to work," Paul Head, a meteorologist at the National Weather Service in State College, said Tuesday.
Head said that areas of higher terrain to the north of Williamsport might get as much as 5 to 6 inches of snow.
"It kind of reminds me of the storm we had the Saturday after Christmas in the morning," Head said. "It's a fast-mover along the front there's a very narrow band of that amount of snow, so it's difficult to predict exactly where that's going to happen."
"We know we're going to get a half-inch of liquid - if it's all snow it's likely to be 5 inches," Head added. "But the temperatures around Pittsburgh are getting close to freezing around 10,000 feet (of elevation), so it's a very difficult call."
The state Department of Transportation was busy laying down an anti-icing salt brine on major highways in the region Tuesday in advance of the storm.
