What you’re looking at is not a Photoshop job but rather a weird cloud formation which is the result of what’s know as a Kelvin-Helmholtz instability.
Captured by a Redditor over Birmingham Alabama yesterday the weird phenomena looks just like rolling waves.
Here’s how Wikipedia describes the effect:
[...] when velocity shear is present within a continuous fluid, or when there is sufficient velocity difference across the interface between two fluids. One example is wind blowing over a water surface, where the wind causes the relative motion between the stratified layers (i.e., water and air). The instability will manifest itself in the form of waves being generated on the water surface.
