If the storm moves off the Virginia and Delmarva coast, central Pa. could face a plowable snow.
Will central Pennsylvania get covered with snow this weekend?
There's a 50-50 chance, said Eric Horst, director of the Weather Information Center at Millersville University.
The storm threat at this point would be Saturday evening into Sunday.
Canadian air will be moving into the region later this week, bringing enough cold air for snow, Horst said. Temperatures will be around 40 on Wednesday and Thursday, and the mercury might not get above freezing on Friday.
A storm is expected to move across the country this week, and its path will determine whether central Pa. gets nothing, a coating of snow or a plowable snow.
If the storm moves off the coast of North Carolina, central Pa. could receive nothing or up to a coating of snow, Horst said.
However, if it moves off the Virginia or Delmarva coast, it would bring a plowable snow to the area. It could be the biggest storm so far this winter.
"The setup is there," he said. "The potential is there."
Meteorologists will have a better idea by Thursday what is likely to happen with the storm, Horst said. The storm is expected to move onto land in California tomorrow.
On Tuesday evening, AccuWeather.com senior meteorologist Jack Boston said he predicts 2 to 4 inches for York County over the weekend. The area could see more or less, depending on the track of the storm.
Baltimore and Washington, D.C. will likely get half a foot of snow, he said.
