   Areas affected...south-central into northeast KS...northwest into
   north-central MO

   Concerning...Severe potential...Watch unlikely 

   Valid 242342Z - 250145Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Strong to locally severe storms will be possible this
   evening, with a threat of isolated hail and strong to severe wind
   gusts.

   DISCUSSION...Storm coverage is increasing early this evening from
   central KS into northwest MO. Storms to the north/northeast of
   Kansas City have developed just to northeast of a warm front and are
   likely somewhat elevated. Persistent low-level warm/moist advection
   will help to sustain these storms as they approach north-central MO.
   Moderate elevated buoyancy (with MUCAPE of 1000-1500 J/kg) and
   sufficient deep-layer shear could support marginal supercell
   structures with a threat for isolated large hail. Also, despite this
   convection being somewhat elevated, a dry near-surface layer beneath
   the elevated moist plume could support some stronger wind gusts this
   evening as storms spread northeastward. 

   Farther west, scattered storm development is ongoing from
   south-central into northeast KS, as a southeastward-moving cold
   front begins to intercept a pre-frontal surface trough and
   relatively greater instability. While low-level moisture remains
   rather limited, strong diurnal heating has resulted in MLCAPE
   increasing into the 500-1000 J/kg range, along with weakening
   MLCINH. Increasing deep-layer flow/shear associated with an
   approaching midlevel shortwave trough will support some organized
   convection through the evening. 

   Rather strong low-level flow (30-40 kt in the 1-3 km layer per
   regional VWPs) and steep low-level lapse rates will support
   potential for strong to locally severe gusts within this regime,
   especially if any organized clustering occurs. Isolated hail will
   also be possible, especially into east-central/northeast KS and
   northwest MO, where somewhat more favorable moisture and buoyancy
   will be in place.
