Mate, you are totally on the right track. "cold" and "warm" is only a human term, to the rest of the universe they are just different amounts of energy and so have potential difference and all that sort of electrical stuff.
the edges of weather fronts or even weather backs can look very much like roll clouds / morning glory clouds / shelf clouds / wall clouds because they are similar. weather people have to say they are totally different but i think we will find out they will mostly be variations of each other. part of the earths electrical weather circuit. wall clouds twist upwards to create tornadoes and have a thin "tail cloud" going into them.
if you look at occluded weather fronts you will see it looks like a power supply - "warm" and "cold" meaning higher and lower enegy difference
occluded weather front diagram or power/energy lines in the weathers circuit?
The weather "fronts" or "rears" that you find some types of Mammatus clouds seem to have
energy lines going into/out of them.
Mammatus clouds (Mammatocumulus or Breast Clouds) seen in Malta
a couple of other things to think about is are some weather fronts pushed or are they pulled and how do clouds in front of a weather system know its approaching?
Some weather fronts will have
streamers/feelers extending forward and you get certain types of clouds that proceed a weather front...
