Deer movement gets more predictable in the deep snow. They tend to have a bedding/loafing area and a feeding area, and a trail in between. They don't wander around as much. It takes too much energy. I'll bet if you find them coming through a certain spot at a given time of day, you'll be able to set your watch by them coming through the same spot, same time, tomorrow.
Good luck, wear your lightest colored and quietest camo. Against snow it's easy to blob out against the background. And, snow sucks up sound. You'll notice the silence. The deer will notice any rustle that breaks it.
