   Explanation of macro, because some of the people reading this likely don't
   know what a ternary conditional is:

   (WeatherAndTime.x==id)  -> transitioning to wanted weather?
   ?(WeatherAndTime.y==id) -> coming from wanted weather?
   ?(1.0)                  -> if so, always 1
   :(WeatherAndTime.z)     -> if not, return transition
   :(WeatherAndTime.y==id) -> not transitioning but coming from wanted weather?
   ?(1.0-WeatherAndTime.z) -> return inverse transition
   :(0.0)                  -> otherwise return 0
