   Areas affected...portions of Indiana

   Concerning...Severe Thunderstorm Watch 91...

   Valid 030021Z - 030145Z

   The severe weather threat for Severe Thunderstorm Watch 91
   continues.

   SUMMARY...Ongoing thunderstorms will continue to pose a risk for
   isolated damaging wind gusts and perhaps a tornado or two over the
   next 1-2 hours.

   DISCUSSION...Several line segments have shown signs of increasing
   organization/intensity across portions of Indiana, with a stronger
   mesovortex producing a report of wind damage in Parke County over
   the last 30-45 minutes. While buoyancy remains weak (250-500 J/kg
   MLCAPE), strong low-level flow and clockwise-curved hodographs
   (45-50 kts at 1 km AGL and ~200 m2/s2 0-500 m SRH, respectively, per
   the IND VWP) will continue to support the potential for line
   segments and embedded mesovortices capable of isolated damaging
   winds gusts and perhaps a tornado or two across Severe Thunderstorm
   Watch 90. Increasing low-level stability owing to nocturnal cooling
   is then expected to mitigate the severe risk with time this evening.
