This is a "hole punch" cloud, also known as a fallstreak hole cloud.

According to National Geographic, "Clouds are made of water droplets, and hole punch clouds occur when part of that cloud falls out, leaving behind a hole. That opening in the cloud is the result of an extremely localized snowfall."

The refraction of sunlight by the snow's ice crystals results in the rainbow.

Pretty cool, huh?
