Clouds often take on a greenish hue before severe storms, but this is most often associated with hail. Hail is usually part of a thunderstorm. These tall, dense cumulonimbus clouds often block most of the sunlight, so the greenish tint may be a reflection of Earth's green foliage. However, the cause of the green tint has not been proven conclusively.

Doesn't hydrogen glow green when it ionizes?

The green glow is excited oxygen losing a green photon when it gets unexcited. Ozone production. Hailstorms have lots of cycling of the hail up and down before it drops out. That involves lots of friciton and the generation of a lot of electricity.

I believe that the green of some lightning strikes comes from the copper in transformers vaporizing. However, I have seen red lightning also, don't know where that comes from.
