    It is most likely getting heated air from the space between the storm door and inside door, and that causes the condensation to freeze. You can try to get one of those foam things that slide onto the base of the inside door to keep air from leaking out into that space, or possibly just replace the thread plate (metal or wood plate on the floor, under the door)

    Agree with Diana. Take a look at the weather stripping all around your steel or wooden door. Something is not right. If it all looks okay, try closing the door on a sheet of paper then pulling it out while the door is shut. Do that the whole way around the door. Anywhere it pulls out easily needs attention.

    Get weather strips and put on the frame. Make sure to always shut the storm door tightly before closing the other door so that there is no air coming in.

    Try cleaning storm door with shaving cream. Works on bath room mirror, so it does not fog up from shower steam.

    It can also happen when you open the door and the heat hits one side and the cold temp outside. I have this happen with our kitchen screen door since this is the most used door in the house.
