   Areas affected...Southeast South Dakota...Northeast
   Nebraska...Northwest Iowa...Far Southwest Minnesota

   Concerning...Severe potential...Watch unlikely 

   Valid 030616Z - 030845Z

   Probability of Watch Issuance...20 percent

   SUMMARY...A marginal wind-damage threat will likely continue for
   several more hours from southeast South Dakota and northeast
   Nebraska into northwest Iowa. Due to the isolated nature of the
   severe threat, weather watch issuance seems improbable at this time.

   DISCUSSION...The latest radar imagery shows a linear MCS from near
   Mitchell, South Dakota extending south-southwestward into northern
   Nebraska to just west of O'Neill. The Winner, South Dakota airport
   recorded a 54 kt wind gust as the line passed through. The line is
   located near and to the northeast of a maximum in instability with
   MLCAPE in the 2000 to 3000 J/kg range, according to the RAP. In
   addition, 850 mb flow of 25 to 30 kt is contributing to
   storm-relative inflow near 40 kt. This environment should help
   maintain an isolated wind-damage threat with the line of storms as
   it moves across the remainder of southeast South Dakota and
   northeast Nebraska over the next couple of hours. Northwest Iowa
   should eventually be impacted.
