A winter weather advisory is in effect until 10 a.m. Thursday in Crawford County.
The National Weather Service said a cold front is moving across the area, triggering some scattered snow showers.
Cold air behind the front will activate lake effect snow bands with winds out of the west to northwest, the forecast said. The heaviest snow will fall in the higher terrain where colder ground temperatures will support more accumulation.
A total amount of 3 to 6 inches is expected.
"Travel could be very difficult," the advisory said. "The hazardous conditions could impact the morning or evening commute."
