   URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 410
   NWS Storm Prediction Center Norman OK
   1125 PM CDT Sat Jun 27 2026

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     North-Central Nebraska
     South-Central and Southeast South Dakota

   * Effective this Saturday night and Sunday morning from 1125 PM
     until 700 AM CDT.

   * Primary threats include...
     Scattered damaging winds and isolated significant gusts to 80
       mph possible
     Scattered large hail and isolated very large hail events to 2
       inches in diameter possible
     A tornado or two possible

   SUMMARY...An evolving bow echo is forecast to continue
   east-northeastward across north-central Nebraska and south-central
   South Dakota into southeast South Dakota tonight. Strong to severe
   gusts are possible with this bow, with a low-probability risk for a
   brief line-embedded tornado as well. Additionally, more cellular
   activity is possible in the wake of this bow, resulting in a
   lingering severe threat across north-central Nebraska and
   south-central South Dakota. Primary risk with this more cellular
   activity is large to isolated very large hail.

   The severe thunderstorm watch area is approximately along and 40
   statute miles north and south of a line from 30 miles north
   northwest of Ainsworth NE to 5 miles northeast of Sioux Falls SD.
   For a complete depiction of the watch see the associated watch
   outline update (WOUS64 KWNS WOU0).

   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 406...WW 409...

   AVIATION...A few severe thunderstorms with hail surface and aloft to
   2 inches. Extreme turbulence and surface wind gusts to 70 knots. A
   few cumulonimbi with maximum tops to 500. Mean storm motion vector
