INFO:

Classic wall cloud presentation from this supercell thunderstorm outside of Hobart, Oklahoma in the southwest portion of the state. Seeing a wall cloud underneath a supercell is alarming to most people -- but wall clouds need to be persistently rotating (with increasing speed) to be dangerous. A lot of the times, supercells have hang-me-downs that resemble wall clouds but aren't -- and often they also have wall clouds that aren't particularly dangerous. A wall cloud is, first and foremost, a visualization of the strongest area of inflow into a storm's updraft. If you see persistent and increasing rotation (think: minutes not seconds) then it's time to prepare for tornadoes. 🎥 - October 10, 2010
