EF1 tornado in Butler County, Nebraska

This tornado touched down about 1 1/2 miles west of Ulysses, traveled east across town and then lifted around 2 1/2 miles east of town. The tornado heavily damaged 4 homes west of town and also caused tree and farm outbuilding damage and flipped dozens of center pivots. Power lines were also downed, causing 500 residents to lose power for 24 hours or more. Homes in Ulysses also sustained damage as did the Farmers Cooperative Elevator. This is the second tornado that spun up from a large supercell thunderstorm that moved across the area.

A stationary front over Kansas started lifting north on June 4th as an unseasonably strong upper level low pressure system was organizing over the central Rockies. This allowed very warm and unstable air to feed north into southern Nebraska and southwest Iowa during the afternoon on the 4th. Severe thunderstorms that developed by early afternoon on June 4 over central Nebraska quickly spread and developed into eastern Nebraska and southwest Iowa through evening. A few tornadic producing supercells developed over the area...and many of the storms contained very heavy rain which fell on soils that were already saturated from significant rains recorded over the prior week. This caused areas of flash flooding and subsequent river flooding.
