Supercell T-storms developed late in the afternoon ahead of a cold front and along a warm front.  The supercell storms produced very heavy rains and some strong wind reports.  The storms also produced several weak tornadoes, however, little or no damage was reported.  In fact, no photos exist of the tornadoes due to the small, short lived nature of the EF0 tornadoes.  The moist air mass and relatively slow storm motion provided a favorable situation for thunderstorms to produce very heavy rainfall as well.  Rainfall rates were estimated at 1 to 2 inches per hour with the heavier activity.  Meanwhile, the very slow movement of the cold front allowed storms to repeatedly move over the same areas.  This caused some extreme rainfall amounts estimated as high as 8 inches, and widespread flash flooding over much of east central Kansas.
