Lake effect snow is snow that falls on the lee side of a lake.

It is generated by cold dry air passing over warmer water. This is most prominent in the Great Lakes region.

The areas affected by lake-effect snow are called snow belts.

Southwestern Ontario is surrounded by water on three sides, many parts of Southwestern and Central Ontario get a large part of their winter snow from lake-effect snow.

In some cases, the snow can fall for days and deposit significant snowfall.
