| Brief Description: An eventual f4 tornado began its destructive path around 6 miles southwest of Coleridge. The tornado moved northeast and crossed the northern sections of the city uprooting trees, downing power lines and destroying a couple of grain bins. A construction business in a garage was also destroyed. The tornado then continued northeast of town hitting a large hog farm. At this farm a 70-year-old man was killed while in a storage shed when a tractor that was flipped by the winds crushed him. Many livestock were also killed by debris or flung through the air by the deadly winds. In one case cattle were carried over a mile then left dead in a pile. The tornado then widened to around 3/4 of a mile, reaching its maximum intensity. Numerous vehicles were tossed at this location and a complete farmstead was flattened. Trees were also stripped and debarked. The tornado remained around 3/4 of a mile wide for a few more miles before turning slightly to the southeast and diminishing, but not before hitting 2 more farmsteads and moving one house off of its foundation. In total, 11 homes received substantial damage and between 100 and 200 utility poles were downed. M70EQ | |||||||||||

| Brief Description: EVENT NARRATIVE: A grain bin was damaged as this tornado initially touched down along with two or three large power line support structures northwest of Crofton. The tornado tracked toward Lewis and Clark Lake taking the roof off of a house and destroying a garage. The tornado also caused other roof damage as it continued tracking toward Lewis and Clark Lake. When it reached the lake it caused significant damage to a recreation area and marina. The tornado also caused 3 minor injuries when it apparently lifted a large SUV off the ground and carried it a hundred feet or so before setting it down with the windows blown in. Numerous campers and boats were flipped or missing at the recreation area, along with vehicle damage. About $1 million in damage was estimated to have occurred at the recreation area. Many trees were also toppled. This tornado and others in Knox county downed 30 to 40 power poles. A Storage building in the area was also severely damaged. This tornado started as one tornado to the southwest was lifting and a weaker one to the northeast was forming. There were several reports by the public of multiple tornadoes in the area, either from the three tornadoes mentioned here, or from multiple vortexes within this tornado. The tornado crossed Lewis and Clark Lake and did f1 damage in South Dakota. EPISODE NARRATIVE: A warm front that was along the Kansas and Nebraska border early Saturday morning May 5th, lifted north during the day bringing widespread heavy rain and severe weather, including tornadoes, to eastern Nebraska and southwest Iowa. The warm front was part of a large upper level system that brought several days of severe weather and flooding to the region. Heavy rain and flooding was reported with some of the activity Saturday morning, along with isolated severe thunderstorm reports. However, during the afternoon the severe weather became more widespread over northeast Nebraska where supercells spawned several tornadoes. At this time, thunderstorms, some severe with heavy rain, produced flash flooding over parts of southeast Nebraska. By evening the severe weather, including supercell producing tornadoes, shifted into southwest Iowa, although isolated severe thunderstorms persisted over parts of eastern Nebraska until after midnight cdt. | |||||||||||
