   URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 283
   NWS Storm Prediction Center Norman OK
   625 PM CDT Sat May 27 2017

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Southwest Illinois
     Central and southern Missouri

   * Effective this Saturday night and Sunday morning from 625 PM
     until 200 AM CDT.

   * Primary threats include...
     Scattered large hail and isolated very large hail events to 2
       inches in diameter possible
     Isolated damaging wind gusts to 70 mph possible

   SUMMARY...Although the near-ground air mass has stabilized in the
   wake of the earlier significant squall line, a very moist and
   unstable air mass advecting atop the stable near-surface air mass
   will support the possibility of some severe hail through the
   evening.

   The severe thunderstorm watch area is approximately along and 50
   statute miles north and south of a line from 65 miles southwest of
   Knob Noster MO to 35 miles northeast of Farmington MO. For a
   complete depiction of the watch see the associated watch outline
   update (WOUS64 KWNS WOU3).

   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.
