Hi Shane,
I am glad you enjoyed the tornado footage - we, David Croan, John Allen and I were absolutely stoked at what we had witnessed. I know there were other better tornadoes observed this year, but for shear relaxation this is one of those events you simply can relax and simply observe. The complex nature of this event and some of the behaviour was unique!
Not sure where you may have heard mentioned of lightning and to what nature? However, tornadic supercells can produce some incredibly powerful bolts and during tornadogenesis, smooth channel lightning is often observed freqenting the developing tornado - remember this is in the region of an updraft with precipitation. I am not sure what otherwise is responsible for the nature of such lightning - but rest assured, tornadoes are not the only danger in some of the cases.
Regards,
Jimmy Deguara
