Event Summary:

An upper level disturbance moving south out of central Canada and onto the northern and central plains, working with a surface boundary draped across the region, brought a round of scattered thunderstorms to portions of the NWS Hastings coverage area during the late afternoon and early evening hours of Tuesday, September 4th.  Though shear and instability were modest at best, some thunderstorms were able to become severe, primarily a cluster which passed east through north central Kansas and far southern portions of Nuckolls and Thayer Counties of south central Nebraska.  Widespread damaging thunderstorm wind gusts of at least 60-70 MPH and heavy rainfall accompanied these thunderstorms, but only one hail report (0.75" diameter) was received.  Locations including Downs, Woodston, Osborne, Stockton and Cawker City in Kansas, as well as Superior and Hebron Nebraska, were affected by these winds.


Some of the notable PRELIMINARY severe weather reports from this event (final reports will be collected over the next several days/weeks):

  • Thunderstorm wind damage in and near Downs, KS (Osborne County) included a carport being blown over, several 6 to 8 inch diameter tree limbs downed and the second story of a house under construction on Highway 24 being knocked down.
