Primarily between 3 and 8 pm CDT on this Friday afternoon and evening, strong to severe thunderstorms blossomed along a fairly narrow, southwest to northeast corridor across the heart of South Central Nebraska, resulting in several hail and wind reports. The vast majority of this activity focused near a weakening cold front within 10 to 20 miles either side of a line extending from near Beaver City-Minden-Grand Island-Silver Creek. A few of the most notable severe weather reports included quarter size hail covering the ground in Edison, ping pong ball size hail in Silver Creek and a measured 60 MPH wind gust at the Aurora airport.
The first, high-based storms of the afternoon flared up in southwestern areas generally between Beaver City and Minden between 3 and 5 pm CDT. These storms were closely tied to the invading cold front, and developed in a deeply mixed environment featuring surface temperatures in the mid-upper 90s F and dewpoints in the mid-50s to around 60. Then between 5-7 pm CDT, storms rapidly expanded into the Grand Island/Aurora vicinity and points north and east, where surface dewpoints averaged a bit higher near a north-south oriented warm front. By 8 pm CDT, the primary round of severe storms had exited east and northeast of the local area. However, even as storms started weakening and moving out of the area between 7-8 pm CDT, strong wind gusts of 54-58 MPH were measured in Adams and Hall counties, likely a result of heat burst activity. During the later evening and overnight hours, additional thunderstorms lingered or moved back into parts of the area, but were non-severe. In addition to convergence along the aforementioned cold front, large-scale forcing for this event was aided by weak shortwave disturbances rippling through modest southwesterly flow, displaced well southeast of a much stronger shortwave trough translating across eastern Montana. Late afternoon mesoscale severe weather parameters across South Central Nebraska featured mixed layer CAPE generally ranging from 1000-2500 J/kg and 0-6 kilometer deep layer wind shear on the order of 30-35 knots.
