   URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 581
   NWS Storm Prediction Center Norman OK
   855 PM CDT Tue Aug 13 2019

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     North-central and northwestern Oklahoma

   * Effective this Tuesday night and Wednesday morning from 855 PM
     until 200 AM CDT.

   * Primary threats include...
     Isolated damaging wind gusts to 70 mph possible

   SUMMARY...Though likely past peak by then, a bowing complex of
   thunderstorms with a substantial pressure/thermal perturbations in
   Kansas still may be producing severe gusts as it enters northern
   Oklahoma.  This activity should weaken as it moves into a
   progressively more-stable low- and middle-level air mass toward the
   southern fringe of the watch area.

   The severe thunderstorm watch area is approximately along and 85
   statute miles east and west of a line from 20 miles northwest of
   Alva OK to 50 miles south southwest of Enid OK. For a complete
   depiction of the watch see the associated watch outline update
   (WOUS64 KWNS WOU1).

   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.

   OTHER WATCH INFORMATION...CONTINUE...WW 579...WW 580...

   AVIATION...A few severe thunderstorms with hail surface and aloft to
   1 inch. Extreme turbulence and surface wind gusts to 60 knots. A few
