It is a good model and seems to hold true to the conditions that we observe relating to lightning.
Heat has substance.
It has a definable mass. It is the weight of this mass that governs the orbitals of electrons. A collection of informative and interesting sites relating to lightning. Good forecasts, satellite, radar ect. I value your imput whether you endorse this theory or not.
