   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Central Nebraska

   * Effective this Thursday afternoon and evening from 330 PM until
     1100 PM CDT.

     Scattered large hail and isolated very large hail events to 2.5
       inches in diameter possible

   SUMMARY...Thunderstorm development/intensification is expected this
   afternoon from south central into east central South Dakota, as well
   as farther southwest into north central and central Nebraska.  The
   storm environment will favor a mix of supercells and multicell
   clusters, with isolated very large hail possible in the first couple
   of hours of any supercell development.  The threat for damaging
   winds will increase as storms merge into clusters by this evening.

   The severe thunderstorm watch area is approximately along and 75
   statute miles east and west of a line from 45 miles west of North
   Platte NE to 40 miles northeast of Huron SD. For a complete
   depiction of the watch see the associated watch outline update
   (WOUS64 KWNS WOU4).

   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.
