A cold front brought isolated to scattered severe thunderstorms with large hail to portions of South Central Nebraska on the evening of August 18th. The first signs of thunderstorm development along the cold front showed itself in Valley County between 3 PM to 4 PM CDT. Temperatures ahead of the front were in the 80s, which was supportive of moderate instability. As instability increased ahead of the front between 4 PM and 5 PM, thunderstorms strengthened and became severe on an isolated basis roughly near the Highway 92 corridor. By 5 PM, a storm near Ravenna in far northeast Buffalo County developed supercell characteristics and began to produce significant amounts of large hail, including up to golf ball size. This storm weakened as it moved southeast through eastern Buffalo County by 6 PM, but a new intense storm developed over central Buffalo County and also became severe and produced large hail just northeast and east of Kearney in the Gibbon area. Around the same time, a lone/isolated supercell developed just north of Genoa along the Boone/Platte County line and quickly became severe. This storm slowly moved south into eastern Nance County between 6:00-6:30 PM, and ended up producing the largest hail of the evening, up to baseball size, in and around Genoa. Significant damage occurred as a result, particularly to crops, vehicles, and roofs. The storm weakened as it moved into Polk County, but still managed to produce severe hail up to ping pong ball size in western Polk County between 7-7:30 PM. Activity quickly decreased in coverage and severity as nocturnal cooling set in between 7:30-8 PM.
