EF1 tornado in Stanton County, Nebraska

This tornado touched down just on the Madison side of the Madison-Stanton County line before crossing into Stanton County less than a mile north of the East Sherwood Road and 558th Avenue intersection. Right as it crossed the county line, it hit a warehouse, blowing off the majority of its roof and blowing in a garage door. Nearby trees just to the south of the warehouse were snapped near the base of their trunks. This tornado continued north-northeast for another half a mile before dissipating. The maximum estimated wind speed from this tornado in Stanton County was 103 miles per hour, and the average width was estimated to be 50 yards.

On the morning of April 26th, a potent negatively-tilted shortwave trough ejected out into the central Plains. Upper air analysis shows a jet streak on the downstream side of this trough with substantial divergence aloft over Nebraska. At the surface, morning cloud cover and drizzle across much of eastern Nebraska and western Iowa quickly gave way to partly cloud skies as a warm front moved north through the area, just after noon. At the same time, thunderstorms initiated along a pacific front/dryline in south-central Nebraska. One supercell produced several tornadoes from south-central Nebraska into Boone County, resulting in an EF-2 tornado just west of Cedar Rapids. A second round of supercells initiated in Jefferson and Saline counties. These long-track supercells produced the worst tornado outbreak the Omaha WFO has seen in 10 years. 5 EF-3 tornadoes were surveyed, with several of these tornadoes just shy of an EF-4 rating. One of these EF-3 tornadoes impacted the northeast side of Lincoln, Nebraska where 70 people were reported trapped in a manufacturing plant that collapsed as the tornado passed. Another long-track EF-3 tornado hit portions of Elkhorn, Bennington and Blair, Nebraska. Eppley Airfield was hit by the third EF-3 tornado of the day, doing damage to aircraft hangars on the southeast side of the airport before hitting homes in far western Pottawattamie County. The last two EF-3 tornadoes of the day both impacted portions of Pottawattamie County. While one remained primarily in rural areas in the central part of the county, the final EF-3 of the day hit the town of Minden, Iowa head-on, resulting in 1 fatality and 3 injuries. This was the only fatality of the entire event. This tornado continued into Shelby County, narrowly missing the towns of Tenant and Harlan. A total of 24 tornadoes were confirmed across both Nebraska and Iowa portions of the Omaha CWA. The strongest tornado was the EF-3 that impacted Elkhorn and Blair, with peak estimated wind speeds at 165 miles per hour.

Along the warm front the day prior, scattered thunderstorms developed along the Kansas-Nebraska border during the evening hours. Most of these storms were sub-severe, however, one thunderstorm produced severe hail in and north of Odell, Nebraska for around ten minutes just before 9 pm CDT.
