Actually...in my experience deer hunting (not going this year due to two little kids in the house), snow isn't a bad thing. Sure, it'll be cold, but a little snow on the ground makes it MUCH easier to track deer. Very easy to see red in show as opposed to gross, mud, etc. A few inches is fantastic. However, a half of a foot or more plus it going on right in the morning at it's worst is not a good thing. Storms can get deer moving, but in my experience is is usually just before or at the start. I heard up north, where I usually hunt, is having a fantastic opening day though weather wise.
