Influenced by a highly unstable, but strongly capped atmosphere ahead of a frontal boundary moving out of Illinois, the combination of 3000 to 4000 j/kg surface based CAPE, mid-level lapse rates between 8 and 9 C/km and 0-6 km deep layer shear of 35 to 55 knots set the stage for rapid supercellular development.  The convection transitioned to clusters of bowing segments as storms congealed producing an increased risk for high end damaging wind.  Broad, but strong rotation established quickly in the initial storms, allowing for rapid production of hail, some exceeding gold ball size.  Numerous funnel clouds were reported in the early stages of the event, indicating conditions were favorable for tornadic development.  However, the development of tornadoes was severely limited due to just enough mixed layer inhibition in the lowest levels.
