   Areas affected...southeastern Indiana...southwestern Ohio...and a
   small portion of northern Kentucky

   Concerning...Severe Thunderstorm Watch 59...

   Valid 200304Z - 200430Z

   The severe weather threat for Severe Thunderstorm Watch 59
   continues.

   SUMMARY...Severe risk continues to gradually diminish across the WW
   area.

   DISCUSSION...Radar data continues to show a gradual decrease in
   convective intensity with storms moving across Indiana/WW 69 over
   the past couple of hours.  This coincides with an associated,
   gradual decrease in buoyancy, with RAP-based objective analysis now
   showing mixed-layer CAPE below 500 J/kg across the WW area, and even
   less with eastward extent toward central Ohio.

   Expectations continue to be that storms will continue to gradually
   weaken, and thus risk for severe-caliber gusts waning.  While local
   WW extension in area may be considered for a couple of counties in
   western Ohio, overall risk should remain minimal for the remainder
   of the evening.
