This has apparently been addressed by the the government:

Can tornadoes be stopped?
You have to consider that the tornado is part of something bigger: the supercell thunderstorm. Unless you disrupt the supercell thunderstorm itself, you would likely have another tornado, even if you were able to destroy the first. The thunderstorm's energy is much greater than the tornado. No one has tried to disrupt the tornado because the methods to do so could likely cause even more damage than the tornado. Detonating a nuclear bomb, for example, to disrupt a tornado would be even more deadly and destructive than the tornado itself. Lesser tactics (like deploying huge piles of dry ice or smaller conventional weaponry) would be too hard to get into the right place fast enough, and would likely not have enough impact to affect the tornado much anyway.
