   Valid 011630Z - 021200Z

   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER PARTS OF
   WESTERN NEBRASKA INTO CENTRAL AND EASTERN SOUTH DAKOTA....

   ...SUMMARY...
   Isolated hail may occur this afternoon and evening from western
   Nebraska into parts of South Dakota.

   ...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.
