   The severe weather threat for Tornado and Severe Thunderstorm
   Watches 56, 58 continues.

   SUMMARY...Damaging winds remain likely with a progressive squall
   line this evening. Isolated tornado risk continues as well.

   DISCUSSION...Long-lived linear MCS (LEWP) continues its forward
   propagation across the Midwest. Leading edge of this strongly forced
   line is advancing across western IN, and several bowing structures
   are surging northeast along this line. One of these features is
   currently over Fountain/Warren County and it will quickly spread
   downstream across Lafayette with an attendant risk for severe. With
   time, this complex of storms should propagate across the remainder
   of the State of IN into Lower MI over the next several hours.
