Best looking tornadic cell that I've seen all day out of the Springfield, MO radar . . .

Image

LSR icon just to the west of the hook reports debris in the air, and the LSR right in the hook is actually two reports, one from law enforcement and one from "tower personnel at SGF" . . . that must be one astounding sight to see . . .
