Tornadoes do not always appear black. The apparent color depends on lighting conditions and how much and what color of soil is being lifted. Many tornadoes appear dark because of perspective: the are lit from behind and are essentially silhouetted against the light source. The same tornado may appear lighter if viewed from a different angle. The storms that spawn tornadoes have very thick clouds that often making conditions appear very dark. The clouds themselves may be black. Some tornadoes may be black as they lift large amounts of black soil into the air.
There are a number of factors. First of all, the ultimate source of a tornado's energy is warm, moist air. Connecticut does not have a climate hot enough for high tornado activity. Second, the types of fronts that often produce tornadic thunderstorms on the Great Plains are often weaker by the time they reach the eastern U.S. and the thunderstorms less organized.
The energy for all weather on Earth ultimately comes from the sun. The sun's energy heats the surface of the Earth, which in turn heats the air just above it. Where the sun heats the surface of the ocean, evaporation occurs, which moistens the air. Warm, moist air carries a very large amount of energy that is the power source for thunderstorms. Thunderstorms are what spawn tornadoes, but not just any thunderstorms. The thunderstorms that spawn tornado typically form along a frontal boundary. Given the right setup of wind patterns at different levels of the atmosphere, these storms can start rotating, turning into supercells. The rotation in the storms can then tighten and intensify to form tornadoes. So, in short, the sun heating the Earth and causing evaporation provides energy that powers thunderstorms. Under the right conditions these storms can start roatating, and their energy can become focused in the form oftornadoes.

Not true
It is reliable
"Credible" is defined as "Being believable, based on information, source or fact." - Something that is credible, is reliable, it's trustworthy.
The simplest answer would be "credible source" information. Many websites on the internet give no source material, or source material taken out of context - if not outright mis-information. Traditional libraries, and their books, normally provide source material for third party conformation of the information they present.
