||Two separate areas of slow moving, hail-producing severe thunderstorms flared up within South Central Nebraska on this Thursday afternoon and early evening, one focused in the Harlan County area and the other farther north in Howard County and vicinity. The majority of hail reports from this event were from the Republican City and Orleans areas, with the largest hail up to baseball size reported several miles northwest of Republican City. The southern storms were the first to develop, and primarily consisted of two supercells that tracked southeast across parts of Harlan and western Franklin Counties between 3 PM and 6 PM CDT, before fizzling out near the Kansas border. As the southern storms started to weaken, a separate area of slow moving, strong to marginally severe storms flared up north of Interstate 80 mainly between 6 PM and 830 PM CDT in the Howard and Nance County area. By 10 PM CDT, all storm activity within the 24-county area had faded away. The initial round of mid-afternoon storms in the Harlan County area developed along the western edge of a sharp instability gradient, in the vicinity of a weak surface trough axis. Aloft, large scale forcing was quite limited, with only subtle shortwave energy embedded within modest west-southwest flow. Around the time of the largest hail in Harlan County, the mesoscale environment featured around 3000 J/kg mixed layer CAPE and 35 knots of 0-6 km vertical wind shear.
