   URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 221
   NWS Storm Prediction Center Norman OK
   535 PM CDT Sun May 24 2020

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     North central into southwest Kansas
     Extreme south central Nebraska

   * Effective this Sunday afternoon from 535 PM until Midnight 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...Thunderstorm development is expected along a stalled front
   from south central Nebraska into southwest Kansas, as well as along
   a remnant dryline extending northward into southwest Kansas, and a
   residual outflow boundary across central Kansas.  The storm
   environment primarily favors a mix of multicell clusters and a
   low-end supercell threat, with storms capable of producing large
   hail and damaging winds.  Isolated supercells in southeast Colorado
   could eventually move into far southwest Kansas later this evening.

   The severe thunderstorm watch area is approximately along and 65
   statute miles east and west of a line from 50 miles north northwest
   of Concordia KS to 5 miles east southeast of Liberal KS. 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.

   AVIATION...A few severe thunderstorms with hail surface and aloft to
   2 inches. Extreme turbulence and surface wind gusts to 60 knots. A
   few cumulonimbi with maximum tops to 550. Mean storm motion vector
   24020.
