I've not seen snow affect things much although I am sure it does. You are not concentrating the weight of the snow in a small area, it is across the entire surface which spreads out the weight. Winds can start the ice moving and then it breaks up and blows to the edges. I remember one year Bear Lake lost all of it's ice in one night due to high winds. I was told the ice at the time was 6 inches thick, which could have been the case at the edges and most likely thinner in the middle. I would suspect that the wind blew the center off and then got under it and and lifted everything.
