   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
   THE SOUTHERN PLAINS AND OZARKS...

   ...SUMMARY...
   Marginally severe wind gusts will be possible over the next few
   hours this evening from central Oklahoma northeastward into central
   Missouri.

   ...Southern Plains/Ozarks...
   The latest water vapor imagery shows west southwesterly mid-level
   flow over the southern Plains and mid Mississippi Valley. At the
   surface, a cold front is moving southeastward across central
   Oklahoma and north-central Missouri. Thunderstorms are ongoing just
   ahead of the front. Surface dewpoints ahead of the front are
   generally in the lower 70s F which is contributing to an axis of
   moderate instability (MLCAPE 1000 to 1500 J/kg). This combined with
   35 to 40 kt of 0-6 km shear evident on regional WSR-88D VWPs should
   be sufficient for a marginal severe threat this evening with strong
   wind gusts possible.
