When winds of different temperatures and humidities meet, tornadoes are formed. In the United States, this usually happens when warm and humid air from the Gulf of Mexico meets cool and dry air from Canada and moves south. Warm air likes to rise, but sometimes when two storm fronts meet, they are trapped under cold air clouds. Warm air can't move upward, but begins to rotate, sometimes pulling the cold air below and intensifying it into a rotating wind funnel extending from the ground to the sky.

Although the storm is very strong, tornadoes are not uncommon in the whole area. According to the data of the National Weather Service, Dallas County suffered about 100 tornadoes in the past 140 years, of which 19 occurred in the past 10 years. Tornado damage-May 20
