Personal snowstorm

I forgot to mention in my previous post about how we create snow everytime we leave the house. When I open the door, the hot "humid" air from inside rushes out to meet the cold air under the roof or our porch, it swirls and a second later snow flies. Its pretty cool to watch. I say "humid" because the relative humidity of our cabin is probably somewhere around .4 percent. Its dry as a bone, but outside is 0.000%
I am sure that we are going to have frost all over the place around the door by the end of winter. We already have frost inside the house in all the corners down by the floor, around all the glass in the windows, and around the door frame.
