   URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 537
   NWS Storm Prediction Center Norman OK
   510 PM CDT Sun Jul 21 2019

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     East central and southeast Kansas
     West central and southwest Missouri

   * Effective this Sunday afternoon from 510 PM until Midnight CDT.

   * Primary threats include...
     Scattered damaging wind gusts to 70 mph possible
     Isolated large hail events to 1 inch in diameter possible
     A tornado or two possible

   SUMMARY...Thunderstorms are beginning to develop from southwest
   Missouri into eastern Kansas along a slow-moving outflow boundary. 
   Strong instability is present south of the boundary, which will
   support some expansion and intensification of the storms through
   this evening.  Transient supercell structures may occur in the first
   couple of hours of the watch, when an isolated/brief tornado cannot
   be ruled out with storms along the boundary.  Otherwise, storms will
   evolve into multicell clusters with the primary threats of damaging
   outflow winds and marginally severe hail.

   The severe thunderstorm watch area is approximately along and 60
   statute miles north and south of a line from 70 miles west southwest
   of Emporia KS to 50 miles east northeast of Springfield MO. 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.

   &&

   AVIATION...A few severe thunderstorms with hail surface and aloft to
   1 inch. Extreme turbulence and surface wind gusts to 60 knots. A few
   cumulonimbi with maximum tops to 600. Mean storm motion vector
   31020.
