with the air mass ahead of it. And that can lead to a tornado developing and getting entrained. You can also have a thunderstorm develop that again, interacts at the low levels with wind shear and it'll suck in a bit of a spinning of column of air. You have conservation of angular momentum as it gets stretched upwards. It turns, it consolidates into a tornado. But the actual parent storm is not rotating at all. So you'll have that, that does occur. And again, non-supercell tornadoes are very difficult to forecast because they sort of just happen. We don't really see them before they happen. They just sort of appear and then they go away very quickly. Supercell tornadoes, usually you can warn those and then there's telltale signs that a tornado vortex may form. That said, non-supercell tornadoes do show up as if the environment's good enough from the radar. It's close enough you'll see a TV asset.
