I've seen the hopping thing you describe (if you eliminate the cloud thing, and it's on a scale of hundreds of miles) with AM radio signals and on short wave signals. However, this just isn't the case for TV reception, except during unusual ionization phenomena.
There can be a height that seems ideal for an antenna on different channels, but in my opinion that height doesn't have any relationship with how far away the station is, or being between hops of the signal. It has more to do with the antenna using the ground to help reflect signal, sort of like using the ground as an extra reflector element on the antenna. However given the choice between extra height and trying to find the ideal height for a particular frequency, I'd choose height every time.
