I just read about this last week in a book. A study was done back in 1995 using a spectrometer to measure the wavelengths of the color spectrum to show that there were indeed more green wavelenths in the sky under some thunderstorms.
Three factors affect the amount of light passing through a cloud, cloud thickness, droplet size, and droplet density within the cloud. So some thunderstorms tend to have a grayish-blue hue because they are dense with a lot of small water droplets. The greenish clouds came from clouds with a lot of larger droplets. Clouds with hail also tend to selectively scatter to that they appear green. A high hail content in clouds also occurs when tornadoes occur.

Skies really don't turn green. What you see is the spectrum of color created by reflection/refraction of light. Remember a rainbow and how it is formed? Same thing with the 'green' sky.

I've seen many tornado's, but I've never noticed the sky turning any shade of green????
