EF2 tornado in Douglas County, Nebraska

This is a continuation of the first Pottawattamie County segment of this EF-3 tornado. In the prior segment, this tornado produced EF-0 and EF-1 damage to a neighborhood in western Council Bluffs, Iowa. This tornado crossed the Missouri River into Douglas County at the start of this segment of its track. This is where the first video evidence of a complete funnel in contact with the ground occurred. This video was taken at the Eppley Airport as the tornado did damage on the southeast side of the Eppley Airfield runway system. The tornado destroyed several aircraft hangars and flipped several untethered executive aircraft, producing EF-2 damage. The tornado continued northeast where it crossed the Missouri River for a second time and moved back into Pottawattamie County. Peak winds during this segment of the tornado track were estimated at 118 miles per hour. The maximum width while the tornado was in Douglas County was measured at 200 yards, with an average width during this track segment estimated at 100 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.
