June 17th Severe Weather Summary

Thursday evening, June 17, 2010, brought a round of severe thunderstorms to parts of south central Nebraska and north central Kansas, with most storms focusing within 15 miles of a line running from Geneva Nebraska to Stockton Kansas. These storms formed along an advancing cold front in a very warm and unstable airmass, and primarily produced large hail and locally heavy rainfall.

Severe Weather:
Here are a few of the "highlights" of the event, based on reports received from storm spotters and local law enforcement/emergency management:

  • Golf ball sized hail approximately 8 miles SW of Kirwin Reservoir in Phillips County at 626 PM
  • Several reports of up to quarter-sized hail and locally heavy rainfall of at least 1-2 inches in the Geneva Nebraska area.

Looking at the big picture, this map of preliminary storm reports from the Storm Prediction Center (through Midnight) shows the narrow axis of mainly hail reports across portions of southern Nebraska and northern Kansas. Please note the much greater concentration of severe weather across Iowa, Minnesota, and North Dakota, including several tornadoes (red triangles)
