Its a double edge sword,A lot of snow will help the big open water lakes form ice weds. night.It will put a lot of weight on the small ponds and hopefully have the water seep up into the snow. It has to be better than a heavy rain taking all the ice away. The snow will have a much more positive effect on ice making than a lot of you are thinking.If it was the middle Jan. its a differant story.At most you may have 4" of ice, less than that will melt when covered by heavy snow,it will take a few days but it will happen. By sat your going to double the ice thickness, and the lakes will freeze over. Do not count out the wind blowing the snow off already frozen ponds.
