   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of

     Western and Central Nebraska
     Southeast South Dakota

   * Effective this Tuesday afternoon and evening from 350 PM until
     1100 PM CDT.

   * Primary threats include...
     Scattered damaging winds and isolated significant gusts to 80
       mph likely
     Scattered large hail and isolated very large hail events to 2
       inches in diameter possible

   SUMMARY...Scattered thunderstorms are forecast to develop along a
   front this afternoon into the evening and grow upscale into a linear
   cluster.  Large hail will be the primary severe hazard this
   afternoon before storms increase in coverage and congeal into one or
   two linear clusters.  Severe gusts will become the primary severe
   hazard during the evening as this activity moves east-southeast
   across the Watch area.

   The severe thunderstorm watch area is approximately along and 85
   statute miles east and west of a line from 35 miles east northeast
   of Chamberlain SD to 20 miles south southeast of Mccook NE. For a
   complete depiction of the watch see the associated watch outline
   update (WOUS64 KWNS WOU4).

   PRECAUTIONARY/PREPAREDNESS ACTIONS...

   REMEMBER...A Severe Thunderstorm Watch means conditions are
   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.
