The following are comments on the observations per my model of tornadoes.

That warm morning of May 3, 1948, my wife and I were sitting in our back yard making small talk, when suddenly she pointed upward and said, "Look how still those leaves are." I was startled. The wind was blowing from the south at about 11 m/s, and there could be no reason in such a remark. But when I looked up at the big blackberry tree I saw what she meant. The wind was so steady and dead-level in its pressure that leaves and small branches were pushed before it and held almost motionless, with scarcely a tremor.

Charged air doesn't have as much turbulence, because the electrostatic repulsion between like-charged particles forces a consistent separation, preventing the pressure fluctuations in turbulence, and encouraging a strictly laminar flow of air. Once charged, objects in that flow, including tree leaves, will be likewise stabilized, resulting in the observed stillness.

Behind the scud cloud a curtain of dark, green rain was falling in a solid, opaque wall.

Green is the color of ionized water.
