   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM WESTERN
   NEBRASKA INTO CENTRAL SOUTH DAKOTA...

   ...SUMMARY...
   There remains a low chance of marginal hail from western Nebraska
   into South Dakota late today and overnight.

   No changes were made to the previous probabilities as a narrow
   corridor of thunderstorms is possible along and north of the front
   from western NE into central SD. While small hail is most probable,
   a 1" hail report cannot be ruled out.

   .PREV DISCUSSION... /ISSUED 1042 AM CDT Wed Apr 01 2020/

   ...NE/SD...
   Latest surface analysis shows a cold front sagging southward across
   parts of SD into western NE.  This boundary will move into a
   slightly more moist and marginally unstable air mass through the
   day, with an increasing risk of showers and a few thunderstorms by
   late afternoon.  Present indications are that a capping inversion
   will preclude thunderstorms ahead of the front, and that the primary
   risk will be elevated storms that form atop the cooler/stable
   near-surface air mass.  A few of these storms may produce hail, but
   the overall severe risk appears quite marginal.
