    What’s going on with the air right before the shock wave gets there??? Did the heat cause condensation or something?

    Pressure wave.

    It can’t be a pressure wave, since that moves at the speed of sound. That’s the shockwave.

    It’s probably thermal in nature –the way you see rings or discs of clouds form above & around a nuke’s mushroom cloud.

    Then again, for all I know it could be some kind of reflection within the camera lens.

    Looks like a lens flare on the camera, stolid. It looks like it is mirror to the actual blast.

    It’s a heat caused “mirage”, fairly common in desert locations. The image (notice it’s a mirror image) isn’t bright enough to see until the flash of the explosion. You see this a lot with lights, both car and building.
