During the late afternoon and evening hours of Thursday, April 29, 2010, a corridor of strong to severe thunderstorms erupted along a cold front across the far southeast portions of the NWS Hastings county warning area. Mainly between 630pm-930pm, these storms dumped torrential rainfall and hail up to the size of golf balls across portions of Thayer, Jewell and Mitchell counties.

Severe Weather:

  • Although tornado warnings were issued for portions of Thayer and Jewell counties based on strong rotation detected by Doppler radar, no reports of actual tornadic activity were received.
  • However, these storms were prolific hail producers, with several reports of quarter to golf ball sized hail, affecting communities such as Jewell, KS and Hubbell, NE.

Heavy Rainfall:

  • Summarized in the tables and graphics below is a partial listing of rainfall totals from April 29-30, 2010, ending around 7 AM on the 30th. These reports are from a variety of sources, including NWS Cooperative Observers and automated systems at area airports and along rivers. A special thanks goes to the CoCoRaHS program and Nebraska Rainfall Assessment and Information Network (NeRAIN) for providing a wealth of precipitation information to the NWS.
  • Please note that the "Top 10" list only reflects rainfall totals accessible by NWS Hastings through "official" sources or via the Internet. It is likely that locally heavy rain also affected portions of the area from which gauge readings were not accessible or known.
