to no tornado warning being issued. In addition, a weak EF0 tornado briefly touched down near Pennsuco, Florida, causing no damage. July 19–20 During the afternoon and evening of July 19, an outbreak of 15 tornadoes impacted Iowa, a few of which were strong and destructive. The outbreak was unusual due its late-season time of occurrence, and due to the fact that it was largely unexpected. The Storm Prediction Center had only issued a slight risk with a 2% tornado risk area in the region prior to the outbreak, and it was only upped to 5% later in the day; an outbreak was never anticipated. This was due to an inaccurate analysis of a low-pressure system over the northern part of the state, which in turn caused the National Weather Service to underestimate how conducive the environment was for tornadogenesis. An EF2 tornado struck the town of Bondurant, causing heavy damage to homes, while a simultaneous and nearly identical tornado caused EF2 tree and outbuilding damage to the north of town. A powerful EF3 tornado struck the east edge of Pella, injuring 13 people and causing major structural damage to large factory buildings at the Vermeer plant, and $120 million in damages. Another damaging EF3 tornado struck downtown Marshalltown, heavily damaging or destroying numerous homes, businesses, and a Lennox International plant, and injuring 22 people, causing $200 million in damages. Several other weak tornadoes also occurred, including an EF0 tornado that caused minor tree and fence damage in Ankeny. On July 20, the Storm Prediction Center issued a moderate risk of severe weather across parts of Indiana, Kentucky, and Tennessee. Damaging winds were the main threat, though the outlook included a 10% risk of tornadoes. Several tornadoes touched down, though all were weak. One EF1 tornado caused considerable damage to homes and barns near Corydon, Indiana, while another EF1 tornado downed trees and destroyed outbuildings in and around the town of Moonville. Twenty-six tornadoes occurred as a result of this outbreak, which resulted in 35 injuries. It also resulted in over $320 million in damages. July 27–29 Throughout a three-day period in late July, scattered tornadoes occurred across portions of the western Great Plains states, a couple of which were strong. Four weak tornadoes touched down in Colorado on July 27, including an EF1 near Byers that tore much of the roof off of a house and flipped a UPS
