A mini tornado in normal atmospheric conditions, can be induced artificially with technology that is not available to public scrutiny, and a larger tornado can be encouraged when the conditions are set up beforehand by nature. Your question in regards to the starting point is intuitive, because they do have a definite starting time and place, which is already formed and working before any obvious signs recorded by the weather watch. If there was any manipulation with technology, it could, in the case of a hurricane only be done with the aid of nature, and so it requires a knowledge of the invisible forces working through matter. Whether an artificial manipulation can be traced or not, is probably something we could not prove now, but will be known about in the future. If you want more info, my other posts in other threads answer some questions, my profile page 16 to 26 or thereabouts. On this forum, I would not expect anything less than verbal abuse and censoring, so there may be a limit to what I can post.
