Lake-effect snow - Wikipedia
When winds become northerly or aligned between 330 and 390°, a single band of lake-effect snow may form, which extends down the length of Lake Michigan. This long fetch often produces a very intense, yet localized, area of heavy snowfall, affecting cities such as La Porte and Gary.
What is a Lake Effect Snow? - National Weather Service
Lake Effect snow occurs when cold air, often originating from Canada, moves across the open waters of the Great Lakes. As the cold air passes over the unfrozen and relatively warm waters of the Great Lakes, warmth and moisture are transferred into the lowest portion of the atmosphere.

Lake Effect Snow | NASA Earthdata
Lake effect snow is generated when cold air moves over warm lake waters such that narrow bands of snow clouds develop. The warmer lake waters heat the lower portions of air, causing it to become less dense and begin to rise.

Jan 11, 2017 · According to these models, by 2050, heavy lake-effect snowstorms become more frequent around Lake Superior. The climate around Lake Superior is colder than that around other Great Lakes, which makes it more able to support snowfall for a longer period of time, even when temperatures warm.
