Atmospheric scientist here.

This kind of cloud is called a shelf cloud, one of the two species of arcus cloud. Shelf clouds form at the edge of the inflow and outflow in big thunderstorms. The convective core sucks air up (inflow) while cold air descends (outflow). The inflow is the upper segment and the outflow is the lower “shelf.” On very large, mature convective cells (like this one) you’ll get a very well defined shelf as both the inflow and outflow strengthen.

That green color is definitely enhanced using post processing. While large thunderstorms produce a ton of optical phenomena, neon lighting isn’t on that list. Some cells will get really nice green lighting in the late afternoon/early morning (yellow light from sun + blue light from rain/hail), but not quite at that hue or luminance.

If anyone has any questions about thunderstorms or severe weather, feel free to let me know!

Nice try, atmospheric scientist. But you can't fool me.

That's a rift in the Space-Time continuum.
