   Concerning...Severe Thunderstorm Watch 80...82...

   Valid 312342Z - 010145Z

   The severe weather threat for Severe Thunderstorm Watch 80, 82
   continues.

   SUMMARY...Strong-severe thunderstorms will sag southeast this
   evening.

   DISCUSSION...Southern edge of stronger westerly flow extends across
   the OH Valley early this evening. Latest satellite imagery suggests
   several weak disturbances are advancing across the Great Lakes
   region with one feature noted over Lower MI/northern IN. This
   low-amplified short wave appears partly responsible for recent
   uptick in convection immediately downstream across northeast
   IN/northwest OH. Radar data suggests a a small MCS is evolving over
   northwest OH and a bow may be forming along the leading edge of this
   activity over Henry/Putnam County. Damaging winds may become more
   common with this maturing complex as it spreads across northwest
   into north central OH.
