It should be noted that the quick freeze up of Lake Erie makes up a large amount of this overall percentage. After being almost ice free to start the year, Erie is 87 percent ice covered as of mid-January.
Lake Erie freezes quicker than the rest of the Great Lakes because its shallower, according to our winter weather expert, Tom Niziol. In a typical winter, Lake Erie usually freezes by Jan. 24, Niziol says.
