Cold air travels over warm lake water. The air becomes warmer, moister, less dense, so that it rises; when it passes over land, the reduced airspace causes the air to "pile up" resulting in "frictional convergence." This lifts the air even further to where it cools, turning into droplets or snowflakes. The result is enhanced snowfall.
