Rainbows in southern Illinois
Rainbows were low across the western sky in southern Illinois following the rain.
The best time to see a rainbow is during the morning or evening when the sun is lower in the sky. Rain is one side of the sky; the sun on the other…most cases...the sun is behind you. The colors are present but we see them with a human eye due to the billions of water droplets and sunlight reflections from the rain.
