Traveled with Derrick Herndon and the Weather Explorers Post #999 out of Bellevue, NE.Left Bellevue/Omaha at 11:00pm on a course to view existing storms that were still moving through eastern SD/IA Border area. Viewed these storms just north of Sioux City on I-29 before continuing west through Vermillion and Yankton SD. We jogged south on Hwy 281, and ended up in Oneill, NE at ~5:00pm. Upon looking for a Library for updates, we noticed the first towers emerging in a moisture convergence region. The cap was broken! We folllowed these towers as they became a classic isolated supercell. Was able to confirm one brief touchdown in photos after enhancing. Also encountered quarter-sized hail.
