Middle to upper level winds were out of the west to southwest, and an upper level disturbance moved over the region from Colorado by the early evening hours. There was a weak surface low to the south with an inverted trough axis over portions of north central Kansas and south central Nebraska extending north of the low. This trough axis set up a frontal zone across Nebraska and Kansas. High based thunderstorms developed to the west of the area along a shortwave trough then moved eastward and encountered increased instability. Mixed layer CAPE was around 1000 to 2000 J/kg and deep layer wind shear was around 50 to 60 knots. There was a slight risk of severe storms from the Storm Prediction Center.
Storms began developing to the west and northwest of the area during the afternoon hours. A cluster of storms moved in from the west and began impacting north central Kansas around 7 pm. This cluster of storms continued moving eastward during the evening hours and extended northward into portions of southern Nebraska. The cluster exited the area around 10:30 pm as it continued tracking eastward across Nebraska. There were several strong to severe wind gusts across north central Kansas and one report of golfball sized hail. One report of thunderstorm wind damage occurred in Mitchell County. The storms went on to produce a few severe wind gusts in Nuckolls and Thayer Counties in Nebraska as well as a wind damage report in Thayer County.
