The distribution of snowfall in the Great Lakes region resulting from lake-effect snowfall is dependent upon several factors: the position of the storm tracks, the degree and variations in lake water temperatures, the extent of ice coverage, prevailing wind directions and the frequency of strong wind speeds. Topographic contrasts to the lee of each of the Great Lakes also affect the intensity and spatial distribution of lake effect snowfall. Lake effect snowfall contributes between 30% and 50% of the annual winter snowfall on the eastern and southern shores of the Great Lakes.

I knew the wind picked up water vapor crossing the lake, if it's not frozen, but hadn't thought of the difference in vapor pressure speeding up the evaporation rate.
