Watch this twister take shape from a wet-classic supercell near Boise City, OK. In the clip you can see the hallmarks of a supercell wrapping up to produce a tornado, from the wet rear-flank downdraft parting to reveal a striking horsehoe cut into the base to the low-level meso wrapping up and producing a tornado under a low-hanging wall cloud shrouded by a bit of rain. Most tornadoes evolve somewhat like this, the super visible ones are very rare indeed. Taken from the roof @Insta360 cam. | Tor
