   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     A small part of south central and southeast Kansas

     1100 PM CDT.

   * Primary threats include...
     Widespread damaging winds and isolated significant gusts to 80
       mph likely
     Scattered large hail and isolated very large hail events to 3
       inches in diameter likely

   SUMMARY...Rapid thunderstorm development is expected soon along a
   cold front in south central Kansas.  The initial storms could be

   southwest, likely affecting the Oklahoma City area close to 7p. 
   Aside from the large hail threat, increasingly widespread damaging
   winds, some significant, are expected across central and south
   central Oklahoma through late evening/early tonight.

   The severe thunderstorm watch area is approximately along and 105
   statute miles north and south of a line from 20 miles east of
   Chandler OK to 30 miles north northwest of Fort Sill OK. For a
   complete depiction of the watch see the associated watch outline
   update (WOUS64 KWNS WOU1).

   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.
