   URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 438
   NWS Storm Prediction Center Norman OK
   610 PM CDT Wed Jun 18 2025

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Southwest Oklahoma
     Northwest Texas

   * Effective this Wednesday evening from 610 PM until 1100 PM CDT.

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

   SUMMARY...Widely scattered thunderstorms are forecast to
   preferentially develop along a boundary draped from west to east
   across the Watch area.  The stronger multicellular thunderstorms
   will be capable of a risk for large hail and severe gusts.  This
   activity will likely weaken by the late evening.

   The severe thunderstorm watch area is approximately along and 30
   statute miles north and south of a line from 40 miles west southwest
   of Childress TX to 50 miles east southeast of Fort Sill OK. For a
   complete depiction of the watch see the associated watch outline
   update (WOUS64 KWNS WOU8).

   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.

to 20% (EF2-EF5 tornadoes), less than 5% to 20% (all other probabilities),
“Moderate” from 30% to 60%, and “High” from 70% to greater than 95%.
High values are bolded and lighter in color to provide awareness of
an increased threat for a particular event.
