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.
