   URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 137
   NWS Storm Prediction Center Norman OK
   910 PM CDT Mon May 3 2021

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Most of western and central Arkansas
     Extreme northwestern Louisiana
     Extreme southern and southeastern Missouri
     Extreme southeastern Oklahoma
     Northeastern Texas

   * Effective this Monday night and Tuesday morning from 910 PM
     until 400 AM CDT.

   * Primary threats include...
     Scattered damaging winds and isolated significant gusts to 75
       mph likely
     Scattered large hail and isolated very large hail events to 2.5
       inches in diameter possible
     A tornado or two possible

   SUMMARY...Clusters of severe storms are expected to spread
   east-northeastward toward Arkansas overnight from eastern Oklahoma
   and northeastern Texas.  There will be a tendency for storms to grow
   into larger clusters and line segments, with an increasing threat
   for damaging winds, with isolated significant gusts possible. 
   Otherwise, any lingering supercells will be capable of producing
   isolated very large hail, and a tornado or two may occur with
   embedded circulations.

   The severe thunderstorm watch area is approximately along and 80
   statute miles east and west of a line from 40 miles north northeast
   of Flippin AR to 5 miles southwest of Longview TX. For a complete
   depiction of the watch see the associated watch outline update
   (WOUS64 KWNS WOU7).

   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.
