Intro. While you were watching the tornado go, someone grabbed your shoulder and that person was Doppler On Wheels 2, or Dow2 for short. As she walks up to take you to get to know her younger sibling, it's Doppler On Wheels3, or the abbreviated name is Dow3. Both of you are the ones who can tell which direction the tornado will go.
