That is a possibility. No one truly knows, and we might not ever know. That's what meteorologists and atmospheric scientists are trying to figure out at this time. But what you're thinking of are parallel rotating columns of air that are lifted vertical due to the updraft of a storm.

That is only a theory, and hasn't been confirmed yet.
