   URGENT - IMMEDIATE BROADCAST REQUESTED
   Tornado Watch Number 284
   NWS Storm Prediction Center Norman OK
   700 PM CDT Sat May 27 2017

   The NWS Storm Prediction Center has issued a

   * Tornado Watch for portions of 
     Northern and western Arkansas
     Southern Missouri

   * Effective this Saturday night and Sunday morning from 700 PM
     until 200 AM CDT.

   * Primary threats include...
     A few tornadoes and a couple intense tornadoes possible
     Widespread damaging winds likely with isolated significant gusts
       to 80 mph possible
     Scattered large hail and isolated very large hail events to 2.5
       inches in diameter possible

   SUMMARY...Severe thunderstorms will continue to develop within a
   highly unstable environment from far southern Missouri into northern
   and western Arkansas. Tornadoes will especially be possible with any
   storm along a roughly west-east outflow boundary along the
   Missouri/Arkansas border vicinity, while semi-discrete supercells or
   evolving line-embedded mesovortices would also pose a tornado risk.
   Otherwise, widespread and locally intense damaging winds will be
   highly likely as storms accelerate east/southeastward this evening.

   The tornado watch area is approximately along and 70 statute miles
   north and south of a line from 60 miles west southwest of Harrison
   AR to 35 miles east southeast of Poplar Bluff MO. For a complete
   depiction of the watch see the associated watch outline update
   (WOUS64 KWNS WOU4).

   PRECAUTIONARY/PREPAREDNESS ACTIONS...

   REMEMBER...A Tornado Watch means conditions are favorable for
   tornadoes and 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.
