   URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 380
   NWS Storm Prediction Center Norman OK
   535 PM CDT Fri Jul 17 2020

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Northern and central Minnesota
     Southeast North Dakota
     Northern South Dakota

   * Effective this Friday afternoon and Saturday morning from 535
     PM until 100 AM CDT.

   ...THIS IS A PARTICULARLY DANGEROUS SITUATION...

   * Primary threats include...
     Widespread damaging winds expected with scattered significant
       gusts to 90 mph likely
     Scattered large hail and isolated very large hail events to 2.5
       inches in diameter possible
     A couple tornadoes possible

   SUMMARY...An intense linear-type complex of storms is expected to
   evolve into a derecho this evening and produce
   widespread/significant damaging winds as it accelerates
   east-southeastward across the region. Isolated large hail is also
   possible, and a tornado risk cannot be ruled out, particularly near
   the warm front.

   The severe thunderstorm watch area is approximately along and 85
   statute miles north and south of a line from 85 miles north of
   Mobridge SD to 45 miles east of Brainerd MN. 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.
