Tornadoes form during thunderstorms, when warm moist air collides with cool dry air but will only form when the atmospheric conditions are just right. One of the great mysteries of science is why one storm will produce tornadoes and another won't. Watch Mutant Weather on Sundays at 7pm on National Geographic UK. | National Geographic UK | Facebook

Here's the video of the weak tornado near London and Lafayette, Ohio. It looked like it tried to occlude as it passed by London but tried to wrap back up as it crossed 42 and lofted debris into the air before voriticies started dancing in the field and impacted the barn doors and sent it flying over 50 yards into the nearby field. Trees were reported snapped behind the Wendy's in my shot as it tracked very close to town. #OHwx | Ohio Storm Chasers
