   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
   THE CENTRAL PLAINS...MID MISSOURI VALLEY AND UPPER MISSISSIPPI
   VALLEY...

   ...SUMMARY...
   Marginally severe thunderstorms with hail and strong gusty winds
   will be possible on Monday from parts of the central Plains
   northeastward into the Upper Mississippi Valley.

   ...Central Plains/Mid Missouri Valley/Upper Mississippi Valley...
   An upper-level trough will move eastward across the northern High
   Plains and central Rockies on Monday. At the surface, a cold front
   will advance southeastward across the central Plains and mid
   Missouri Valley. Surface dewpoints ahead of the front are forecast
   to increase into the upper 50s and lower 60s F as weak instability
   develops along the front during the late afternoon. It seems most
   likely that thunderstorms will develop by early evening along the
   front from the central Plains northeastward into the upper
   Mississippi Valley with this convection spreading eastward during
   the evening. Forecast soundings Monday evening from southeast
   Nebraska into southeast Minnesota have enough instability for an
   isolated severe threat suggesting hail and strong gusty winds will
   be possible. However, weak buoyancy should keep any severe threat
   marginal across the region Monday evening.
