   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Southeastern Indiana
     Extreme northern Kentucky
     Much of western and central Ohio
     Lake Erie

   * Effective this Wednesday afternoon and evening from 245 PM
     until 1000 PM EDT.

   * Primary threats include...
     Widespread damaging winds and isolated significant gusts to 75
       mph likely
     Scattered large hail events to 1.5 inches in diameter possible

   SUMMARY...A broken band of severe storms across Indiana is expected
   to spread eastward through the afternoon, with additional storm
   development likely into Ohio.  Eventual upscale growth into a more
   solid squall line is expected by this evening.  The storm
   environment will be favorable for embedded bowing segments and
   supercells capable of producing damaging winds, some significant.  A
   tornado or two and isolated large hail will also be possible with
   the stronger storms.

   The severe thunderstorm watch area is approximately along and 60
   statute miles east and west of a line from 35 miles east northeast
   of Toledo OH to 50 miles southeast of Cincinnati OH. For a complete
   depiction of the watch see the associated watch outline update
   (WOUS64 KWNS WOU7).

   PRECAUTIONARY/PREPAREDNESS ACTIONS...

   favorable for severe thunderstorms in and close to the watch area.
   Persons in these areas should be on the lookout for threatening
   weather conditions and listen for later statements and possible
   warnings. Severe thunderstorms can and occasionally do produce
   tornadoes.
