The formation of lake-effect snow depends on multiple factors, effecting the thresholds of temperature needed in the air and water masses. In the United States this phenomenon is most noted along the south and east shores of the Great Lakes during arctic cold-air outbreaks. envoPolar The factors involved in this process are complex, and expert input is needed to refine this. Similar input is needed to create bay-effect and ocean-effect snow. @Brandon: add axioms to relate this concept to proximity to a `lake`; perhaps using colocation and spatial region? lake effect snow lake-effect snow decreased temperature dry
