- A supercell storm as it nears tornadogenesis
- W912230S
- A view to the northwest of the supercell in W912221S a while later, as the storm nears tornadogenesis. Now the entire side of the storm is visible and the mesocyclone with attendant circular banding is prominent. The rings stand out against the lines in the cloud layer above, which parallel the southeast surface winds blowing toward the storm.
