   ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER PARTS OF THE
   CENTRAL AND SOUTHERN HIGH PLAINS...

   ...SUMMARY...
   Isolated severe thunderstorms are possible from eastern Colorado
   into Kansas, and southward across west Texas and Oklahoma. Large
   hail and locally strong wind gusts will be possible with this
   activity.

   ...Synopsis...
   Midlevel winds across most of the CONUS will remain relatively weak
   today, the exceptions being from the Great Lakes into the Northeast,
   and into the Southwest late. However, embedded disturbances
   associated with ares of thunderstorms will influence their nearby
   environments, with 35-45 kt speed at 500 mb. In the upper levels,
   the split flow regime is more apparent with stronger westerlies
   across the Southwest, Mexico, and the southern Plains, while rising
   heights and stronger anticyclonic flow shift into eastern Canada. 

   At the surface, southerly winds around the western Atlantic high
   will maintain low-level moisture off the Gulf over the southern
   Plains and Southeast, again resulting in areas of moderate to strong
   instability from KS into West TX. A boundary will stretch roughly
   from southern Lower MI into KS through much of the day, with a
   surface trough from the OK/TX Panhandles south.

   ...Central and southern Plains...
   MLCAPE on the order of 2000-3000 J/kg appear likely to develop today
   south of the synoptic front from southern KS into western OK and
   West TX. Some potential may exist for a marginal MCS over OK or
   northern TX, but this is uncertain. However, any residual boundaries
   that survive may provide a focus for new development later in the
   day. The greatest threat will develop from southern KS into West TX
   during the late afternoon and into the evening. Here,
   widely-scattered, slow-moving supercells are again expected, with
   primary risk damaging hail. Isolated severe hail is expected as well
   over eastern CO, where substantial instability will develop with
   steep lapse rates. A few cells may trek eastward across the KS
   border during the evening.
