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.
