Lake-effect snow showers developed Tuesday afternoon on the 17th as westerly flow was in place and colder air moved into the regio. By early evening, a passing upper disturbance shifted winds to the northwest, allowing a lake-to-lake connection between Lake Huron, Georgian Bay, and Lake Ontario and helping maintain lake-effect snow across portions of the area.

The episode as NWS BGM wrote it up.
Lake-effect snow showers developed Tuesday afternoon on the 17th as westerly flow was in place and colder air moved into the regio. By early evening, a passing upper disturbance shifted winds to the northwest, allowing a lake-to-lake connection between Lake Huron, Georgian Bay, and Lake Ontario and helping maintain lake-effect snow across portions of the area. A general 6 to 11 inches of snow fell over the Southern Tug Hill Plateau. High pressure ridging built in early Wednesday morning, bringing an end to the lake-effect snow around sunrise of the 18th.
