This late Friday evening kicked off a stretch of four consecutive nights of strong-severe storms within South Central Nebraska. This opening act featured damaging wind gusts of 60-65 MPH along the leading edge of a line of severe thunderstorms across far west-northwest portions of the area, with all severe weather reports confined to western Dawson and Valley counties between 950-1100 pm CDT. A few of the most notable reports included estimated 60 MPH gusts in Gothenburg, measured 63 MPH gusts at the Ord airport, and a machine shed destroyed approximately 11 miles west of Ord. Although severe weather only impacted a small portion of South Central Nebraska, widespread non-severe storms tracked across many areas north of Interstate 80 all night long and even past sunrise on the 22nd. Rainfall totals in most places measured no more than 1-2 inches, although an isolated much-higher amount of 3.60 inches was reported 7.5 miles west-northwest of Genoa.
Severe storms initially flared up in western Nebraska during the late afternoon and early evening hours before tracking east toward northwest portions of South Central Nebraska, generally along and near a weak cold front roughly bisecting Nebraska from southwest-to-northeast. Shortly before entering the local area into western Dawson County, storms organized into a generally north-south oriented squall line, sending severe outflow winds surging out ahead. As the line tracked just outside of the local area across Custer County, the leading edge started to bow out, enhancing damaging gusts as the outflow raced into Valley County between 1030-1100 pm CDT. Shortly thereafter, the outflow surged well-ahead of the main area of storms, diminishing the damaging wind threat by midnight CDT. Large-scale forcing for this event was aided by subtle disturbances passing through the Central Plains in modest southwesterly flow aloft, along the southeast periphery of a broad trough anchored by a Pacific Northwest closed low. In addition to convergence along the aforementioned surface front, the nocturnal upscale growth of storms was aided by the development of a 40-50 knot southerly low level jet evident at 850 millibars. Late evening severe weather parameters in South Central Nebraska featured mixed-layer CAPE around 2000 J/kg and 0-6 kilometer deep layer wind shear around 35 knots.
