Thunderstorms produced lots of hail close to the Kansas state line on this Thursday morning. Some of the hail was as large a tennis balls. Between 5 and 6 AM CST, a lone thunderstorm developed over Furnas county. This storm rapidly developed into a supercell and produced tennis ball size hail just south of Orleans, and 2 inch hail near Republican City. This storm subsequently moved east along Highway 136, producing severe hail between the size of quarters and golf balls all the way to Superior. As this storm was in progress, other storms began developing along Highway 136. However, the only other storm to become severe occurred over northeast Nuckolls and northwest Thayer counties, where it produced hail up to the size of golf balls. The supercell ceased producing severe hail after Superior as it merged with other storms over Thayer county and become multicellular. For a while, storms trained along Highway 136 through 11 AM CST. There was one report of 2.08 inches of rain over southwest Thayer county.
During the nighttime hours, a strong cold front had been sagging south through Nebraska. By dawn, it had dropped into northern Kansas, but its forward progress had slowed to the point that it had temporarily become stationary. While this occurred, weak low pressure moved out of southeast Colorado into southwest Kansas. This increased the lift atop the front which resulted in the elevated storms atop the cooler air mass. The morning radiosonde launch at North Platte, NE indicated southeast winds at 30 kt at 850 mb, just above the frontal surface. The upper-level flow was zonal across the majority of the U.S., but observed flow in the mid-levels showed that there was a subtle shortwave trough at 700 mb. MUCAPE was just over 1000 J/kg with very steep mid-level lapse rates of 8 C/km. Deep layer shear from the lifting condensation level was between 35 and 40 kt.
