A storm expected to pass over the York area could drop 3 to 4 inches of snow Friday night before pounding New England over the weekend, according to the National Weather Service.

The storm, which is forecast to move northeast along the Appalachian Mountains before reaching Pennsylvania, probably will hit York Friday afternoon, said Aaron Tyburski, meteorologist with the weather service in State College.

It could arrive as early as Thursday, depending on the path the storm takes, he said.

It's too early to closely predict accumulation, but the storm is projected to move too far east to mean much for York, he said. The storm is more likely to intensify after it has passed York, meaning a very snowy weekend for New England, Tyburski said.
