   URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 431
   NWS Storm Prediction Center Norman OK
   1040 PM CDT Mon Jun 17 2024

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     South-central and east-central North Dakota
     Central and northern South Dakota

   * Effective this Monday night and Tuesday morning from 1040 PM
     until 600 AM CDT.

   * Primary threats include...
     Scattered damaging winds and isolated significant gusts to 75
       mph possible
     Scattered large hail and isolated very large hail events to 2
       inches in diameter possible

   SUMMARY...Increasingly organized thunderstorms are expected to grow
   in coverage and move northeastward across the watch area over the
   next several hours.  Though north of a warm front and nominally
   elevated in character, this activity still may penetrate severe
   gusts to the surface, as well as producing sporadic large hail.

   The severe thunderstorm watch area is approximately along and 75
   statute miles either side of a line from 70 miles west southwest of
   Pierre SD to 5 miles north northeast of Jamestown ND. 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 65 knots. A
   few cumulonimbi with maximum tops to 500. Mean storm motion vector
   23035.
