Actually a storm like that can either get them moving early looking for food, or they bed down and sit tight. Especially if there isa lot of hunting pressure. Thats why when it snows, I like to sneak around and try and catch one in their bed. Especially if I can find a fresh track, I walk that out and normally will find them either standing around with their face in the wind, or in a bed laying cross ways to the wind (why they do that I have no idea). I've shot a lot of deer in bed. How they got in my bed we'll never know...
