One storm produced severe hail during the early morning hours, then more storms produced severe hail and near-severe wind gusts in the evening on this Wednesday. Around midnight, a strong squall line was moving out of western Nebraska into central Nebraska. To its south, numerous small cells developed between McCook and Franklin. Just after 12:20 a.m. CST, nickel to quarter size hail was reported in Edison. More storms formed with several short line segments moving across south central Nebraska during the night. The resultant mesoscale convective system completely exited the region by 8 a.m. CST. The rest of the daylight hours were quiet. A small cluster of multicell thunderstorms formed over southwest Nebraska during the late afternoon. This cluster began moving into south central Nebraska after 7:30 p.m. CST. It affected all of south central Nebraska north of Highway 6 until 11:30 pm CST. These storms produced widespread strong winds of 50 to 55 mph. There were a few severe gusts measured, the highest of which was 70 mph near the town of Norman in Kearney County and Bertrand in Phelps County.
Very little in the pattern had changed from recent days. A north-northeast to south-southwest oriented quasi-stationary front extended from the eastern Dakota's south through the Plains into New Mexico. Several weak lows were along the front, one over the Dakota's, another over Kansas, and another over southeast Colorado. In the upper levels broad southwest flow was over much of the United States, with a ridge over the Great Lakes, and an elongated trough from the Canadian Prairies to southern California. Temperatures had cooled into the lower 70s by the time the thunderstorms began to move into the region. Dewpoints were in the lower to middle 60s. However, with mid-level lapse rates around 7.5 degrees C/km, MUCAPE was 2000-2500 J/kg. MLCAPE was around 2000 J/kg. Effectively deep layer shear was 40-45 knots.
