EF1 tornado in Kearney County, Nebraska

This tornado touched down in the area of the golf course, then moved southeast through the northeast part of town, just south of the airport. The ground circulation was likely small and somewhat disorganized at this stage, as most of the damage in town was to trees. The tornado grew in intensity on the northeast outskirts of town, where a couple metal buildings sustained roof and overhead door damage. The tornado appeared to track along the highway northeast of town before crossing into a corn field and overturning pivots. Based on storm chaser video, this is where the condensation funnel was largest and most obvious. The end of the track between 33 Road and 34 Road was confirmed by drone video submitted to the NWS. The estimated peak wind gust of 90 MPH and EF1 rating is based on the tree damage at the golf course and the damage to the metal buildings on the edge of town. The tornado width of 200 yards is estimated based on observed damage and storm chaser video. Extensive tree damage was noted further south across Minden, and appears to be the result of an intense rear flank downdraft surge of straight-line wind.

A broad, upper trough was over most of the country, including Nebraska. An upper disturbance passed over the central Plains which created enhanced lift. CAPE values of around 2,000 J/kg, wind shear of around 40 to 50 knots, and mid-level lapse rates of 7 to 8 degrees C/km were over south-central Nebraska. Temperatures were mostly in the 70s to lower 80s. These conditions resulted in an atmosphere that was conducive for severe storm development.
