Clouds in the shape of a portal..in Tennessee. shows a circular cloud formation with the sun shining through, creating a ring of light. This is likely a result of a rare weather phenomenon called a "fallstreak hole", also known as a "hole punch cloud".
It occurs when the water droplets in the cloud are supercooled, meaning they are below freezing but haven't yet frozen into ice crystals. When something disturbs the cloud, like an airplane passing through, it can cause the supercooled droplets to freeze rapidly, falling out of the cloud and leaving a hole.
