The air takes on a heavy, thick feeling and everything is completely still. The sky has a greenish yellow tinge to it... within hours there are tornadoes... why does the sky turn yellow?
The last time I saw this happen was around 6 pm in Tampa the evening before a couple of tornadoes obliterated parts of two counties in Florida about 40 or 50 miles north of where I had been.

Every time I've seen this, there's no sunlight breaking through the cloud-cover... it's just blank greenish-yellow... and creepy-feeling.

Here we go, one of my favorite subjects. A tornado is a vortex. It is a combination of lows highs, cool air and warm air causing a whirl pool type action. Tornado's don't actually suck things into the air. The vortex that has been created actually causes items, things, and debris to be lift up through the center of the vortex. Most of the yellowish color is dust. When clouds are green take cover, it is hail. This is normal with tonadic storms. The green is a reflection of ice forming in the clouds.
Most damage occurs from the high winds the vortex creates. During many tornado's, the vortex can lift heavy objects, like cars, people, houses, and whatever, through the center and eventually after the vortex settles down it can deposit them several miles away. The yellow is from dust, sand and debris exiting from the top of the vortex into the atmosphere.
This is still under scientific research as to why and how.
Search on Google for Vortex. Especially Oregon Vortex.

I have seen it green before a tornado too.
I thinki it is just the way the light is bent by the thick clouds.

The high levels of dust and water vapor in the air alter the refractive properties, so different wavelengths of sunlight get through. It's similar to the effects of smog.

That's a good question, I've noticed that also. Dust lifting into the air around the impending 'spin-point', or eye?
