   AREAS AFFECTED...CNTRL AND NRN KS INTO SRN NEB

   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 

   VALID 212243Z - 220045Z

   PROBABILITY OF WATCH ISSUANCE...20 PERCENT

   SUMMARY...SCATTERED STORMS WITH GUSTY WINDS AND HAIL ARE POSSIBLE
   THROUGH EVENING BUT THE THREAT SHOULD REMAIN DISORGANIZED.

   DISCUSSION...VISIBLE SATELLITE SHOWS A CONCENTRATED AREA OF TCU AND
   A FEW THUNDERSTORMS FROM CNTRL INTO NRN KS WITHIN A ZONE OF ENHANCED
   CONVERGENCE NEAR THE LOW PRESSURE TROUGH. STRONG HEATING HAS ERODED
   CIN...AND A STRENGTHENING SLY LOW-LEVEL JET BODES WELL FOR CONTINUED
   DEVELOPMENT THIS EVENING AS CIN WILL BE SLOW TO INCREASE DUE TO A
   RATHER DEEPLY-MIXED AND MOIST BOUNDARY LAYER.

   GENERALLY EXPECTED TO MOVE SLOWLY WITH A NEWD COMPONENT. LOCALIZED
   SEVERE WIND AND HAIL WILL BE POSSIBLE...BUT COVERAGE PERHAPS TOO
   SPARSE FOR A WATCH.
