Isolated reports of severe winds and hail occurred after midnight on this Wednesday. During the evening hours of Tuesday, scattered thunderstorms were over southwest Nebraska. Around midnight CST, these storms began to intensify, and the easternmost storms began moving into south central Nebraska. One storm tracked across Furnas, Harlan, and Franklin counties, just north of Highway 136. This storm probably produced severe hail along much of its track but, due to the time of night, the only report received was quarter size hail in northwest Franklin county. Storms south of North Platte grew upscale into a short squall line that exhibited a bowing structure at times. This line of storms entered Gosper and Furnas counties around 130 AM CST. It continued moving southeast, affecting Harlan county as well, through 3 AM CST. Measured wind gusts of 69 MPH and 63 MPH were reported near and 6 miles east of Oxford, respectively. The northern portion of this line merged with the isolated severe storm over Franklin county. Meanwhile, a short east-west oriented line of storms erupted over Webster and Nuckolls counties around 230 AM CST. As this line blossomed, the squall line to the west quickly moved in and merged with it, with the squall line dominating the progression of the convection. The squall line continued moving east-southeast, affecting Thayer county as well through 430 AM CST. Hail up to 1.25 inches in diameter was reported in Ruskin, and winds were measured as high as 58 mph just south of Deshler. The duration of heavy rainfall was maximized over western Nuckolls county, where the east-west line developed, followed by the northern end of the squall line moving east from Webster county. This resulted in a swath of more than 2 inches of rain, with the highest amount 2.83 inches 8 miles northwest of Superior. In Ruskin, 2.48 inches was measured.
These storms occurred along and near a cold front that was associated with occluded low pressure over North Dakota. A fairly potent shortwave trough was over the Dakota's, embedded within the Westerlies which were located across the Northern United States. Just ahead of the thunderstorms, temperatures were in the lower to middle 70s, and dewpoints were in the lower 70s. Mid-level lapse rates were 6.5 to 7.0 deg C/km, resulting in MUCAPE between 2000 and 3000 J/kg. Effective deep layer shear was 35-40 kt.
