   ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE
   MIDWEST/OHIO VALLEY AND CENTRAL PLAINS...

   ...SUMMARY...
   Severe thunderstorms are expected on Wednesday, particularly across
   parts of the Midwest/Ohio Valley and central Plains.

   ...Midwest/Ozarks/Ohio Valley...
   Moderate to strong destabilization is expected within a moist air
   mass preceding an east/southeastward-moving cold front, potentially
   effectively augmented by early day convection and residual cloud
   cover. As a shortwave trough transitions northeastward over the
   Great Lakes toward Ontario, at least weak height falls and
   moderately strong mid-level westerlies will generally influence
   areas as far south as the Ohio River and parts of the Ozark Plateau.
   Intensifying multicells/banded clusters seem probable into Wednesday
   afternoon, with bouts of wind damage as the primary hazard through
   the evening. This scenario currently appears most probable across
   downstate portions of Illinois/Indiana into Ohio and northern
   Kentucky.

   ...High Plains/Central Plains...
   Height falls and a strengthening of cyclonically curved westerlies
   are expected ahead (east-southeast) of an amplifying mid/upper-level
   trough over the northern Rockies. At least isolated severe storms
   capable of hail/strong wind gusts will be possible within a broad
   north/south corridor from the western Dakotas and southeast
   Montana/northeast Wyoming southward into eastern Colorado, northeast
   New Mexico, and northwest Texas. A more focused area of potentially
   severe storms, including possible evening-time MCS development,
   would appear to be across western Nebraska/northeast Colorado into
   western/northern Kansas.
