Tornadoes are the most violent storms on Earth; violently rotating columns of air exceed 100 mph and can reach up to 300 mph.
The strongest tornadoes are often near the edge of the updraft, not far from where air is descending in a downdraft caused by the thunderstorms with falling rain or hail.
Most tornadoes form from thunderstorms.
You need warm, moist air from the Gulf of Mexico and cool, dry air from Canada.
When these two air masses meet, they create instability in the atmosphere.
The signs of a tornado forming are.
A dark, often greenish, sky.
Wall clouds or an approaching cloud of debris.
Large hail often in the absence of rain.
Before a tornado strikes, the wind may die down and the air may become very still.
A loud roar similar to a freight train may be heard.
