   URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 179
   NWS Storm Prediction Center Norman OK
   245 PM CDT Wed May 13 2020

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Western Oklahoma
     The eastern Texas Panhandle and the Texas South Plains

   * Effective this Wednesday afternoon and evening from 245 PM
     until 1000 PM CDT.

   * Primary threats include...
     Scattered large hail and isolated very large hail events to 2.5
       inches in diameter likely
     Scattered damaging wind gusts to 70 mph likely
     A tornado or two possible

   SUMMARY...Thunderstorm development is expected along a dryline in
   west Texas during the next 1-2 hours.  Storms Will likely form from
   an area of developing cumulus clouds west-northwest of Lubbock and
   more isolated storms along the dryline toward the northeast Texas
   Panhandle.  The storms near Lubbock will tend to be high based and
   capable of producing damaging outflow winds and hail as convection
   grows into a larger cluster late this afternoon/evening.  The storm
   environment could support supercells with isolated very large hail
   across the eastern Texas Panhandle with the more isolated, initial
   storms.  A tornado cannot be ruled out, especially if any discrete
   storms can persist as far east as the western Oklahoma border. 
   Otherwise, a cluster of storms will likely spread into western
   Oklahoma this evening with an attendant threat for damaging winds
   and hail.

   The severe thunderstorm watch area is approximately along and 85
   statute miles east and west of a line from 75 miles north northwest
   of Clinton OK to 75 miles south southwest of Childress TX. For a
   complete depiction of the watch see the associated watch outline
   update (WOUS64 KWNS WOU9).

   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.

   &&

   AVIATION...A few severe thunderstorms with hail surface and aloft to
   2.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A
   few cumulonimbi with maximum tops to 550. Mean storm motion vector
   27020.
