Multiple rounds of convection developed on June 26th across southern Indiana.  In all, three episodes of heavy thunderstorms contributed to localized flash flooding. The last two episodes, arriving during the mid-afternoon and mid-evening hours, brought wind damage and one tornado that damaged Tell City, Indiana.
At the beginning of the day, southern Indiana lay in a very humid airmass, with dewpoints in the lower 70s.  During the pre-dawn hours, the remains of a decaying nocturnal mesoscale convective system brought widespread substantial rains to southern Indiana.  Portions of Washington and Orange Counties received from one to two inches of rain. This convective system didn't penetrate very far into Kentucky before dissipating, leaving a relatively undisturbed airmass for later in the afternoon.  A second wave of storms moved southeast across the same area during the mid-afternoon hours.  These were surface-based and brought localized flash flooding and wind damage.  The final round of storms moved through around mid-evening, supported by a strong digging shortwave moving southeast across Illinois.  This final round of storms brought additional flash flooding, damaging winds, and a tornado.  A CoCoRahs spotter in Fredricksburg, Indiana, measure 7.22 inches for the entire day.  This rain led to minor flooding on the Blue River at Fredricksburg on June 27th.
