Strike from a Wall Cloud

Strike from a Wall Cloud

A new mesocyclone developed on the front flank of a fast-moving, mean, nasty, heavy-precipitation supercell, then raced past us to the NW and N. For a short while, the rotating but ragged wall cloud area wasn't wrapped completely in rain yet, and this brilliant CG split the fading daylight. My satisfaction with seeing this--at least our fourth supercell of the day in western Iowa--later was dampened when I learned that the same storm (previous mesocyclone) had produced the killer tornado at the Little Sioux Scout Ranch.
