In the early evening hours of April 26, 2024, a powerful multiple-vortex tornado caused catastrophic damage to the small town of Minden and impacted several farmsteads in rural Shelby County. The tornado resulted in one fatality and three injuries and tracked 40.91 miles (65.84 km), reaching a peak width of 1,900 yd (1,700 m). The tornado was the longest tracked tornado of the tornado outbreak of April 25–28, 2024 and tied for the largest tornado of the outbreak, tying with the Elkhorn–Blair tornado. The tornado was the Costliest of the outbreak, inflicting $112 million in damage.

The tornado touched down east of McClelland, staying at EF0 strength for the first few miles before abruptly intensifying to mid-range EF2 intensity south of Minden, while a tornado emergency for the community and surrounding area before the tornado struck the town at high-end EF3 strength. Several residential homes received major to complete destruction from the tornado. Many businesses in town were severely damaged or flattened with estimated wind speeds of 160 mph (260 km/h). Northeast of town, the tornado inflicted more severe damage to farmsteads and a church was destroyed. The tornado reached its peak width south of I-80, tracking through Harrison and Shelby County while missing Shelby and Tennant, and passing west of Harlan, where it was observed by Doppler on Wheels. The tornado became then rain-wrapped as it missed Defiance before dissipating north of the town after being on the ground for 1 hour and 4 minutes.

Another cluster of thunderstorms developed in the Permian Basin of Texas in the early overnight hours into April 26,^[1] becoming and maintaining severe characteristics as they tracked northeast into the Red River Valley.^[2] This cluster eventually organized into a quasi-linear convective system over southern Oklahoma, potentially producing at least one tornado.^[3][4] The Storm Prediction Center (SPC) received three reports of tornadoes from Oklahoma during the early morning hours of April 26; seven weak tornadoes were later confirmed in the state.^[5]

More significant severe weather was expected to occur later on in the day. The event was first forecasted to occur on April 20, when a 15% risk area was issued across much of the south-central United States by the Storm Prediction Center for April 26.^[6] By April 23, the 15% area had been expanded tremendously, covering areas from the eastern Great Plains into the mid-Mississippi Valley.^[7] On April 24, the 15% risk area transitioned into slight risk area that covered the same area with all severe weather hazards expected.^[8] With an enhanced risk of severe weather in place, the Storm Prediction issued a tornado watch for eastern Oklahoma on the morning of April 26.^[9] Several hours later, on the afternoon of April 26, another tornado watch was implemented for northeastern Nebraska, which included the possibility for "a couple of intense tornadoes."^[10] At 3:41 p.m. CDT, a tornado emergency was issued for West Elkhorn as a large and destructive tornado moved through the area. Some homes were completely leveled and many more structures suffered significant damage.^[11]

The supercell that later produced the Minden tornado first crossed into Iowa, then the supercell produced its first tornado north of Pacific Junction. This tornado traveled north towards I-35, inflicting minor damage to trees and power poles along 195th Street.^[5] The tornado crossed the interstate before striking the community of Pacific City at high-end EF0 intensity. Trees along I-35 were snapped and a home northwest of Pacific City lost large portions of its roof at mid-range EF1 strength.^[12] The tornado then trek through forested areas, snapping several hardwood trees with wind speeds up to 100 mph (160 km/h). Eventually the tornado dissipated over the Pony Creek Park, the tornado was on the ground for five minutes and traveled 2.7 mi (4.3 km), with a peak width of 80 yd (73 m).^[12]

The supercell recycled and produced another tornado east of the small community of Dumfries at 5:08 p.m. CST. The tornado was initially weak, inflicting minor damage to hardwood trees along Aspen Road. The tornado slightly strengthened to low-end EF1 intensity, blowing down power poles along County Road G66.^[5] Continuing its northeast trajectory, the tornado intensified to near high-end EF1 east of County Road L45, snapping multiple hardwood trees at 107 mph (172 km/h). The tornado weakened slightly along Burgan Avenue, snapping more trees at 95 mph (153 km/h). The tornado crossed Chestnut Road, causing major roof damage to a double-wide mobile home at low-end EF1 intensity.^[13]

The tornado abruptly intensified to high-end EF2 strength west of Treynor. Alongside Highway 92, a well-built home suffered substantial loss to their exterior walls at 135 mph (217 km/h). An 85-year-old elderly woman survived the tornado after not making it to shelter in time.^[14] Another home nearby sustained significant roof damage by the tornado. Several trees were snapped and a large shed was demolished, and a large steel trailer was thrown a quarter mile away.^[13][5] The tornado weakened substantially to high-end EF0 intensity crossing into Greenview Road, bending a free-standing pole and causing minor damage to a hardwood tree. The tornado then crossed Cottonwood Road, intensifying slightly to mid-range EF1 intensity. A farmhouse sustained minor damage and a roof of a small barn was ripped off.^[5] Along Dogwood Road, the tornado rapidly intensified to low-end EF3 strength, with estimated wind speeds of 145 mph (233 km/h). A poorly-constructed farmhouse was obliterated and swept away. Several trees nearby were snapped and an outbuilding nearby was leveled.^[13][5]

The tornado weakened significantly to high-end EF1 intensity along Elmtree Road. More trees were snapped and a nearby home sustained moderate roof damage. The tornado passed near the community of Quick, weakening further as wooden power poles were snapped at wind speeds of 100 mph (160 km/h).^[5] Southwest of McClelland, the tornado briefly strengthened to low-end EF2 intensity, causing moderate roof damage and snapping more trees. Around the same time, the supercell began recycling again, causing the former tornado to substantially weaken before dissipating over an open field near McClelland at 5:28 p.m. CST. The tornado traveled 13.31 mi (21.42 km) with a peak width of 900 yd (820 m). The tornado was on the ground for 20 minutes.^[13]

As the McClelland tornado started dissipating, the supercell recycled and produced the Minden tornado at 5:25 p.m. CST. For the first few miles, the tornado mainly stayed in rural areas of Pottawattamie County. The tornado crossed Morton Avenue east of Underwood at EF0 intensity. An outbuilding was unroofed and trees sustained minor damage. The tornado began to intensify and widen on approach to Minden. Hardwood and softwood trees along Sumac Road and 330th Street received minor to moderate damage at high-end EF0 strength. The tornado continued northeast, destroying an outbuilding at EF1 intensity along Sycamore Road. The tornado intensified further along Keg Creek, several trees were snapped along the bank of the creek at EF2 intensity.^[5]
