Scene notes:

… in the distance over barn, a strange formation, a slow vortex. An atlas cedar guards over a barn, which seemingly has a small rainbow right next to it in the left portion of the frame. A meadow comprises an eighth of the frame, under growing shade from the setting sun, look west. Observed is a cloud that is raining, known as a ‘Cumulonimbus’ cloud. These clouds are chaotic in many ways from the knock-on effects that are local from so much air moving in different directions. It is eventually inevitable that an ‘eddy’ in the sky, or a small vortex, will sometimes form. This funnel-shaped cloud is by no means dangerous, as its spin only resolves to the naked eye in time-lapse.
