19:27Z EF0 KUEX NE Kearney Newark This tornado started in Kearney County north of Minden and crossed into Buffalo County, lifting near Gibbon. This tornado was typical for the day, likely intermittent with regard to ground circulation and impacting rural areas. Much of the path damage can be traced to center irrigation pivots either partially or fully overturned. The tornado damaged a couple power poles and peeled back some roofing material at the Rowe Sanctuary. A measured wind gust 83 MPH was recorded at the sanctuary as the storm passed. Damage was a bit sparse north of the river. The tornadic circulation likely crossed Interstate 80 about three miles west of the Gibbon interchange before knocking over a couple more pivots and lifting just southwest of Gibbon. The maximum estimated speed of 85 MPH was based upon the measured wind gust at the sanctuary and damage to nearby power poles.

21:03Z EF1 KOAX NE Platte Platte Center A tornado developed over an open field south of town and north of the creek where it tipped over two sections of an irrigation pivot. The tornado proceeded north northeast into Platte Center, causing damage to a garage and snapping several trees. The maximum damage occurred between 2nd and 4th streets where a large metal building with wood construction had the wind enter the doors, uplift the roof, and collapse the walls as the entire building shifted and collapsed to the northeast. Very large trees were blown down and one home lost much of its roof. The damage became less notable over the next block and dissipated near the elementary school.
21:04Z EF2 KOAX NE Platte Columbus A narrow, fast-moving, tornado began in the parking lot of a business along Howard Blvd where it tipped over a semi trailer and proceeded to cause roof, siding, fence, and tree damage. Approximately one block later, it caused the worst damage of the entire track where an attached garage and entire roof were removed from a ranch home. Much of the roof was deposited 20 to 100 yards downstream. The tornado proceeded to produce sporadic damage over the next two blocks and then a more consistent damage path for a 6 block period where many homes had minor to moderate roof damage and several trees were snapped or uprooted. There was then another 5 blocks of sporadic minor to moderate tree and roof damage followed by a 2 block stretch of continuous minor to moderate roof and siding damage. The tornado then travelled across open fields until reaching the Indian Hills neighborhood where it snapped two power poles and caused generally minor damage to a fence and shingles, with no further damage downstream. The entire 2.7 mile track occurred in approximately 2 minutes.
21:11Z EF2 KOAX NE Saline Dorchester This is segmnent 1 of 3 of an EF-2 tornado that began in northeast Saline County where it overturned numerous irrigation pivots. This tornado continued northeast into It continued northeastward into Seward County.

Other outbuildings and grain bins were also damaged in this area. The tornado continued northeastward and passed near the southeast end of Pawnee Lake, damaging power poles in the area. The path continued northeastward, damaging trees and eventually crossing Highway 34 just east of Malcolm Road before dissipating shortly thereafter.
21:27Z EF1 KOAX NE Colfax Howells An intermittent tornado tracked from south to north through Howells. The initial damage point was roof damage to a home on the south side of town along with moderate tree damage. The tornado then skipped several blocks before removing a portion of the building attached to the feed and seed. Nearby security cameras provided video evidence of the brief tornadic circulation on the north side of town. The tornado remained intermittent as it travelled into an open field to the northeast, depositing debris in the field.
21:31Z EF2 KOAX NE Cuming Monterey A tornado developed in a field near 3rd road south of C road and quickly moved northeast to cause roof damage to large animal barns where a substantial amount of roofing tin were removed. The tornado proceeded across open fields before severely impacting a farm near 4th and E road. The farm place had a small shed blown approximately 100 yards. A second brand new larger shed was completely destroyed and a very large shed with equipment inside was also completely destroyed. There was minor roof and siding damage to the home and to another large shed, as well as some fences. The tornado proceeded northeast to another hog farm where it removed large sections of roof from two large barns. The debris were deposited well into a field downstream. The track was then intermittent for 1.5 miles as there were few if any available damage indicators in ag fields before it caused additional damage to 5 power poles and another animal barn where much of the barn was removed and blown into the nearby trees. The tornado appeared to dissipate at that point.
21:37Z EF1 KOAX NE Cuming Monterey An intermittent path of damage across open fields but also managed to snap off power poles in multiple locations, and also caused damage to a shed.

Unable to survey northern end of track due to terrain and no road.
22:14Z EF1 KOAX IA Mills Tabor The tornado began in the hills and rough terrain near Pease Rd and Quigg Ave, and traveled quickly northeast along the 10 mile track, lasting approximately 9 minutes. The first few miles of the tornado track were intermittent, with occasional evidence of a narrow track of damage and some substantial damage to outbuildings and trees. The damage became much more consistent as the tornado approached US Highway 275 where it damaged several outbuildings, including destruction of a well-constructed metal buildings with wooden frame. Security camera footage at this location supported the likelihood of this being caused by a tornado due to sudden directional and vertical shifts in wind which the removal of the roof and walls was completed in only 1 to 2 seconds. The tornado track continued northeast where it caused substantial tree damage, destroyed two sheds, caused minor damage to homes and snapped numerous power poles. Even at this location where the damage footprint was relatively wide, the individual tornado vortices were small, with a significant swath of wind along its eastern flank. The tornado continued north with gradually decreasing damage intensity and sporadic nature of damage.

Property damage costs are a rough estimate.
22:24Z EF2 KOAX IA Pottawattamie Weston A narrow but strong tornado tracked along Road L34 through Sherwood Country Estates before ending near Juniper Road. The maximum damage was sustained to a home in Sherwood Country Estates where the narrow tornado removed the majority of a homes roof and damaged other nearby homes as well.
22:25Z EF2 KOAX IA Woodbury Bronson The tornado spun up two miles northeast of Bronson along 190th Street, around one mile west of the intersection with Emmett Ave, where it ripped a portion of the roof off a single family home and damaged an outbuilding, with debris sent 100 yards to the north into a field. The tornado continued northeast across open fields until it hit two large metal utility transmission towers, and deposited the electric lines across U.S. Highway 20, resulting in the closure of U.S. Highway 20 east of Lawton for two days. The tornado crossed U.S. Highway 20 less than a mile east of Lawton, then made a more northward turn. As the tornado approached Fayette Avenue, it impacted multiple farmsteads with damage to a few barns and sheds, as well as broken and snapped tree limbs. A machine shed at one farmstead was completely destroyed along with a concrete silo and lean-to shed. Multiple power poles were snapped along 140th Street. Minor damage was also noted to shingles on a couple single family homes.|The tornado eventually lifted near the intersection of 110th Street and Fayette Avenue.

The tornado then impacted and snapped several wood power poles but did not cause any additional significant or highly focused damage.
22:31Z EF2 KOAX IA Pottawattamie Bentley A narrow EF-2 tornado began producing damage near Mahogany Road and 290th St and tracked north northeast into the southeast edge of Neola and then caused intermittent damage near Railroad Highway North of Neola. The most significant damage was to a home along 290th street where the roof was removed and walls blown out. A nearby garage was moved off of its foundation and approximately 10 mature trees were all uprooted behind the home with substantial damage to hardwood trees in the front yard. The narrow nature of this tornado was evident in the damage path as nearby barns on the east side of the track had low-end damage, possibly owing to the significant forward speed of the tornado. The tornado was seen briefly by the resident before seeking shelter. A business on the southeast side of Neola also had substantial damage to large metal buildings, at least two of which were destroyed.
22:34Z EF1 KOAX IA Pottawattamie Macedonia A tornado tracked from east of Macedonia to east of Oakland, causing intermittent damage to trees, outbuildings, and homes along the track.
