About 70% rain coverage is expected on Monday.
A mysterious green light was spotted in the clouds above Anna during Thursday's storms. Explaining the science of what it wasn't... and simplicity of what it was.
This peculiar optical effect happens because of the interaction and scattering of sunlight with all of the water and ice that's suspended in the air by the intense updrafts of these supercell thunderstorms. When sunlight passes through the hail, the shorter blue and green wavelengths get scattered more effectively than the longer red wavelengths. As a consequence, the blue and green colors dominate the scattered light, giving rise to the distinct green hue that colors the sky.
This scattering is known as Rayleigh scattering. It’s the same process responsible for the blue color of the sky on a clear day. During severe weather events with hail, however, the presence of big chunks of ice alters the scattering process, leading to an unusual greenish appearance of the sky. The intensity of the green coloration can vary depending on factors such as the size, volume and density of the hail, the angle of sunlight and the overall composition of the atmosphere. In some cases, the green skies may appear more subtle. In other cases it can be vivid and striking, creating a surreal and captivating visual.Alas -- and perhaps unfortunately -- this wasn't that.
