John has talked of this in the past. No, there is not enough moisture in river, creeks and ponds and also not enough suface area to create the lake effect supply.
That is the layman's explanation. John can be more specific if he wants, but I thought I would help since I know for a fact that he is sleepy-night-night already.
thanks for jumping in john, checked out what else was posted also. was by the mississippi river and there seemed to be more snow near the river than a little further away and was just wondering.
