Thunderstorms produced severe hail and wind mainly west of Highway 183 on this Sunday afternoon and evening. A broken line of thunderstorms developed from northwest to southeast across the state of Nebraska during late in the afternoon hours. In the portion affecting central and south central portions of the state, a couple storms over the eastern portion of this line briefly turned severe, producing hail up to 1.5 inches in diameter in parts of Valley County. This portion of the line then dissipated, but storms from Custer County westward continued to increase and organize. By 7 pm CST, a cluster of severe storms had developed over southwest Custer and Lincoln Counties. This cluster became a small-scale squall line and, between 7 and 11 pm CST, it advanced to the south-southeast, affecting parts of Dawson, Gosper, and Furnas Counties before it exited into Kansas. This squall line produced mostly 1 inch hail in several locations. Damaging winds also occurred with the highest measured gust 72 mph at the Cambridge airport. Tree limbs were also snapped off just east of Cambridge, and some of them were very large. Around 1045 pm CST, some other storms initiated over Kearney and Franklin Counties, and they moved into Adams and Webster Counties. One of these storms produced some marginally severe hail with some small tree limbs snapped off.
These storms formed in an areas of relatively high surface pressure. A slow-moving cool front was north of the initiation area, extending from the Great Lakes across Iowa and then northwest across the Dakota's. In the upper-levels, the Westerlies were fairly zonal, but contained multiple low-amplitude shortwave troughs. One was over Nebraska and Kansas. When the storm first developed, temperatures were in the lower 90s with dewpoints in the lower to middle 60s. Mid-level lapse rates were steep (7.5 C/km), resulting in MLCAPE of 2000 to 2500 J/kg. Deep layer shear was around 25 kts and supportive of multicell storms.
