This article found in the New York Times is about a recent tornado in South Dakota, this past week. This tornado destroyed homes by breaking windows and creating holes in the rooves of houses. There was even a record size piece of hail measuring about the size of a cantalope, eight inches across, and is almost two pounds. Along with the cost of a blizzard, the town has to add on the cost of damages done by the tornado. There is an estimated 112 million dollars done in damaged from the combined costs of the tornado and blizzard. This article also includes how during a past summer, there were sixty seven (67) tornadoes on the ground in one day, naming that day "Tornado Tuesday".
