Separate clusters of strong to severe thunderstorms affected portions of South Central Nebraska on this Sunday evening, mainly between 7-11 p.m. CDT. A southern area of storms was mainly a wind-producer, while a northern cluster primarily yielded hail. Focusing first on southern counties, a surge of strong-to-severe outflow winds crossed the state line out of northern Kansas mainly between 8:30-10:30 p.m. CDT, promoting a number of sub-severe gusts into at least the 40-56 MPH range within several counties mainly south of Interstate 80 and along and east of Highway 281. Only a few personal weather stations breached severe-criteria, including a 59 MPH gust near Nelson. In addition, a spotter estimated 60 MPH winds in central Webster County. These winds kicked up quite a bit of blowing dust, including in Hastings, where a 54 MPH gust occurred without any associated rainfall. Turning to the completely separate northern area of convection, a more isolated storm cluster blossomed over Buffalo County around 7 p.m. CDT. Over the next few hours, this activity drifted slowly northeast and occasionally dropped severe-criteria hail, including quarter size stones in or near Ravenna and Dannebrog, and up to ping pong ball size in St. Paul. This convection departed eastward out of Nance County (and thus out of the local area) around 11 p.m. CDT.
Tracing the southern storm complex back to its roots, it actually originated in east-central Colorado during the early-to-mid afternoon before peaking in intensity over north central Kansas during the early evening. In the mid-upper levels, the main instigator for both areas of storms was a low-amplitude shortwave trough lifting east-northeast along the Nebraska-Kansas border. At the surface, convection was largely tied to a slow-moving cold front traversing the Central Plains from west-to-east.  Evening mesoscale convective parameters in South Central Nebraska featured around 1000 J/kg mixed-layer CAPE and 30-40 knots of effective deep-layer wind shear.
