Overview

An isolated supercell developed in the mid-evening hours on July, 25 and produced a tornado in Loup County.  The tornado remained over rural portions of the county, so thankfully outside of some broken tree limbs, very little damage was reported.  The environment was favorable for rapid storm development.  The supercell formed along a dry-line that advanced east across the Sandhills during the evening hours.  The storm weakened as it moved to the southeast.  The results of the survey are preliminary as the National Weather Service will continue to investigate any further report.  If you have storm footage or damage reports from this event, please relay your report to the National Weather Service in North Platte.
