Severe weather was widespread across south central Nebraska on this Thursday afternoon and evening, mainly south of Highway 6. This was the second day in a row of numerous thunderstorms that produce prolific amounts of severe hail. Just as with the previous day, scattered thunderstorms developed early. Some were isolated single cells while other were organized into broken lines that still exhibited some cell individuality. By mid afternoon, one of these lines had organized from west to east across most of Dawson and Buffalo counties. This line moved southeast and expanded during the subsequent hours. By 6:30 p.m. CST, the most intense portion of the line had exited into northern Kansas. There were a couple isolated storms that formed ahead of this line. Most of the severe weather occurred south of Highway 6 with these isolated cells as well as within the line, between the times of 3 and 6 p.m. CST. Several storms produced severe hail, but the largest hail occurred with discrete supercells that produced tennis ball size hail in Furnas County and three inch hail over Thayer County. Damage reported was severe with the Thayer County storm. Vehicles were dented, windows were broken, vinyl siding was damaged, and crops were decimated. There was so much hail with some of these storms, that the ground was turned white. The storm over Webster County contained strong winds which were measured as high as 69 MPH.
These storms formed along and head of a strong Canadian cold front. In the upper-levels, a trough was over the central United States, and an embedded shortwave trough was moving into the Central Plains. In the pre-storm environment, surface temperatures had climbed into the lower 80s, with dewpoints in the upper 50s and lower 60s. Mid-level lapse rates had increased from the day before and were between 7 and 7.5 degrees C/km, resulting in MLCAPE was between 1500 and 2000 J/kg. Deep layer shear was 40-45 knots, with 0-3 km SRH 100-250 m2/s2.
