An Arctic cold front moved rapidly southeast across the lower Ohio Valley on the evening of the 11th. Rain changed to a brief period of freezing rain, then to sleet during the overnight hours.

Snow amounts were greatest over western Kentucky, with amounts of 3 to 5 inches common. A few areas observed as much as 7 inches of combined snow and sleet accumulations.
