A slow-moving cluster of strong to severe thunderstorms rumbled along a path from the northwestern corner of Buffalo County to northwestern Adams County between the evening of Friday the 22nd into the very early morning of Saturday the 23rd, yielding a few reports of marginally-severe hail and winds, along with heavy rain and localized flooding. Isolated thunderstorms started developing around 8 PM CDT near the northern edge of the Dawson-Buffalo County line. Over the next few hours, activity gradually increased along a NW-SE swath line as it impacted northern/eastern Buffalo County and eventually entered Adams County. The training of initial storms brought heavy rainfall to northern portions of Buffalo County, with amounts as high as 3 to 4 inches reported, mainly falling between 10PM-1AM CDT. Creeks in the Pleasanton area were reported to be running full, and some rural roads were covered with water. The strongest storms produced quarter to golf ball size hail in the Pleasanton, Gibbon, and Kenesaw areas. Wind gusts near 60 MPH were reported near Shelton.
Upper level flow across the region was west-northwesterly and generally on the weaker side, as the area sat on the north side of high pressure centered over the Four Corners region. By early-late evening, the surface weather map showed low pressure setting up over western Kansas into far southwestern Nebraska, with a weak boundary extending into portions of central Nebraska. Convergence along the nose of an increasing low-level jet was the main driver of this activity. Though instability was plentiful, with MUCAPE values exceeding 3000 J/kg initially, deep layer shear was lacking, with values around 30 knots. With upper level support on the subtle side, overall coverage of thunderstorms in South Central Nebraska remained low through the overnight hours.
