   Areas affected...Northwest Indiana

   Concerning...Severe Thunderstorm Watch 546...547...

   Valid 092049Z - 092215Z

   The severe weather threat for Severe Thunderstorm Watch 546, 547
   continues.

   SUMMARY...A locally greater wind threat is evident in northwest
   Indiana.

   DISCUSSION...KLOT and TMDW/TORD radar velocity data suggest a
   locally greater wind threat developing in northwest Indiana. Two
   small bowing segments are evident with around 50 kt outbound
   velocities. Given the strong heating and large buoyancy ahead of
   these storms, they will likely pose a locally greater severe wind
   threat over the next 1-3 hours. Depending on the persistence of
   these storms, additional extensions of WW 547 may become necessary.
