qThe amount of snow that falls during lake-effect snowstorms depends on (1) lake temperature, (2) air temperature, (3) wind direction and speed (affect air resident time), (4) ice cover on the lake, (5) topography downwind of the lakes.
qThe temperature difference between air and lake has to be larger than 10°C (18°F) to develop the lake effect.
qThe air-lake temperature is largest in late December and early January, the most favorable time for lake-effect snow.
