Question: Why use a green screen doing weather rather than a white or black screen? What's the reason for the particular color?

Green screens are a popular visual effect (VFX) tool. The green screen (Which is also known as a chroma key) allows a selected color to be transparent so other images can be overlaid on the screen.

Green screens are a popular visual effect (VFX) tool. This is the camera's view of the green screen.

Green is the color of choice because people are not green. With the lights figured in, there is no chance of a person becoming transparent while at the green chroma key. The only time green becomes a problem is when the person is wearing green clothing or jewelry.

Black or white screens are more limiting and may cause additional problems if someone has different skin tones or hair colors.

Green is not the only color used by meteorologists, there are also blue screens used by TV stations. 

The control room overlays weather maps on the green screen. This is how viewers see the maps on their TV.

Question: Do all tornadoes travel straight east?

Eastward or northeast movement is the most common direction tornadoes travel. Their parent storms (primarily supercells) tend to dictate the direction the tornado moves, in most cases moving from west to east.

However, this is not always the case and you can get tornadoes traveling west with what’s called left moving supercells. In squall lines sometimes tornadoes have a northward movement. So while the east is the most common direction, tornadoes can actually travel in any direction. Their movement can be unpredictable and you may see them suddenly backtrack along their path. So while west or east or southwest to northeast movement may be a good rule of thumb, it's not a scientific law.
