Supercell thunderstorms developed along a nearly stationary frontal boundary across Central and South Central Kansas during the late afternoon hours. The highly sheared environment lead to the supercells producing tornadoes between Wichita, Kansas and Winfield Kansas. The supercell thunderstorms evolved into a complex of thunderstorms during the early morning hours of June 13th, 2008. The complex of thunderstorms moved slowly over Southeast Kansas producing flash flooding.

The tornado caused minor damage to a couple of homesteads.

The tornado moved across open country and caused no damage.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 20:04 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

26 more were confirmed in the United States that day.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
