   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS IN A PORTION OF
   THE CENTRAL GREAT PLAINS...

   ...SUMMARY...
   Isolated severe thunderstorms, with a primary threat of large hail,
   are possible on Wednesday evening/night across parts of the central
   Great Plains.

   ...Synopsis...
   A northern-stream shortwave trough is expected to dig southward from
   the Canadian Rockies into the northern Intermountain West. A
   southern-stream, lower-amplitude shortwave trough will drift towards
   the southern CA coast. A pair of lee cyclones will develop near the
   Black Hills and the CO/KS border area by Wednesday evening.

   ...Central Great Plains...
   Just-in-time modified moisture return from south TX is anticipated
   by early evening, yielding potential for isolated high-based
   thunderstorm development near the southwest KS/far northwest OK
   border area. This portion of the dryline, to the east-southeast of
   the aforementioned cyclone, will have the best chance of sustaining
   deep convection with overlap of the low-level thermal ridge/weak
   buoyancy. Substantial veering of the wind profile with height could
   support a high-based supercell or two with severe hail/wind. 

   The 00Z HRW-FV3 is a distinct outlier in indicating potential for a
   discrete supercell deeper into the evening across south-central KS,
   that impinges on greater low-level moisture amid enlarged low-level
   hodograph curvature. Bulk of guidance otherwise suggests  a
   substantial increase in MLCIN after sunset as the low-level jet
   intensifies from west TX into KS, with convection probably
   struggling given the sub-optimal moisture relative to the stout EML.

   Elevated convection should form later Wednesday night into early
   morning Thursday, along the leading edge of the 700-mb warm front
   and towards the exit region of the low-level jet. Although this
   convection may remain rooted near 700 mb, favorable speed shear
   through the cloud-bearing layer should offer a risk of isolated
   severe hail overnight towards the Lower MO Valley.
