A special treat to those who saw the scattered showers — double rainbows, said Storm Center 7 Meteorologist Kirstie Zontini!

For you to see a rainbow, remember the sun needs to be behind you with the rain out in front of you. It also can't be too high in the sky, 42° or less, and finally, the sun's rays need to be shinning or hitting the actual raindrops.

Now a single rainbow is special, but a double rainbow is more unique. A single rainbow is created when the sun's rays reflect once inside of the drop. If the sun's rays reflect twice inside the raindrop, a double rainbow will be created. The double reflected light exits the raindrop at a different angle and will appear above the primary bow.
You'll notice the primary rainbow has much more vivid color and the second bow which is on top, is usually dimmer. Another interesting thing to see is that the colors of the primary and secondary bows are actually reversed, due to the second reflection of light in the drop. The main bow will have red on the top of the arch but the secondary bow will have red on the bottom!
