I had a friend who is a meteorologist looks at this. While his comment may be more technical that I expected, his last point is excellent. 

“This is a low-precipitation (LP) supercell, which represents the least moist supercell within the supercell-spectrum.  

The spectrum, from greatest moisture content to lowest, is composed of the high-precipitation (HP) supercell, the classic supercell, and the LP supercell.  

LP supercells tend to form on the dry-line (a surface moisture discontinuity, with drier air to the west of the dry-line, and moister air east of it.

LPs do not generate much in the way of rainfall, but almost always produce large hail stones (baseball size and larger) that drop like bombs from the sky.  I lost many a windshield to LP supercells back in my storm chasing days.

The lowest part of the cloud reveals rotation perpendicular to the ground surface, which shows up quite conspicuously here in this photo, is known as a "wall cloud."  It is from the wall cloud area of the storm that tornadoes form.

LP supercells are not prolific tornado producers, but when they do generate them, they are incredibly photogenic; although generally weak in nature.

Most people don't believe these photos are real.  And while most of the photos are clearly edited, the morphology of the storm is not changed during post-processing.  That's the way they really look.”

Yeah, the cloud structure is real, but the colors.......?

Unknown, but even in B&W the image is powerful!

Amazing looking storm, but she could have walked 50-100m down the road to get the powerlines out of the shot :)
