Event Summary:

An upper level disturbance moving through the Northern and Central Plains brought a bout of strong to severe thunderstorms during the daytime hours on Wednesday, May 30th, primarily between 10 AM and 5 PM. Starting out during the mid-morning hours across western portions of the NWS Hastings coverage area, activity gradually spread mainly east across portions of South Central Nebraska, especially along and south of Interstate 80, through the early afternoon, before finally starting to shift and develop farther south across portions of North Central Kansas.   Even though the instability across the area was not overly impressive, the cooler low to mid level air mass and deep layer shear more than compensated, resulting in numerous hail reports through the day.   By early evening, activity across the local area started to wane, with the primary focus shifting into central and southern portions of Kansas as well as the Southern Plains.

Some of the notable severe weather reports from this event:

  • 60 MPH winds were reported in Beloit, KS as well as near Eustis (4 miles northeast) and Lexington (5 WNW).
  • Golf ball size hail (1.75") was reported in Bertrand and near Cozad (2 SE). 
  • Ping pong ball size hail (1.5") was reported in Ionia, KS.
  • Half dollar size hail (1.25") was reported near Cozad (1 E).
  • Quarter size hail (1.0") was reported at a number of locations, including Johnson Lake, Gothenburg and Holdrege.  Reports also came from near Elwood (9 N), Davenport (2 N) and Jewell, KS (7 SSW).
  • Numerous reports of penny (0.75") to nickel size (0.88") hail from across the area.
