   ...SRN PLAINS/MID MS VALLEY...
   
   EXPANSIVE CLUSTER OF CONVECTION APPEARS TO BE EVOLVING INTO AN MCS
   OVER SERN KS/OK THIS MORNING WITH A POSSIBLE WEAK MVC FORMING WEST
   OF ICT.  THIS ACTIVITY IS LIKELY BEING DRIVEN BY WARM
   ADVECTION...WHICH ABRUPTLY ENDS ACROSS WRN OK/NWRN TX COINCIDENT
   WITH BACK EDGE OF CONVECTION.  CURRENT SPEED/MOVEMENT SUGGEST MID-
   UPPER LEVEL DRYING WILL SPREAD ATOP COOL BOUNDARY LAYER BUBBLE IN
   WAKE OF EARLY MORNING CONVECTION.  WITH RAPID COOLING EXPECTED AT
   MID LEVELS...RESIDUAL MOISTURE WILL PROVE MORE THAN ADEQUATE FOR
   RENEWED THUNDERSTORM DEVELOPMENT BY 18Z-20Z ACROSS PORTIONS OF
   WRN/SWRN OK...JUST NORTH OF MAIN DRY SURGE.  WITH STRONG SUNSHINE
   EXPECTED ACROSS NWRN TX...DEEP MIXING WILL ALLOW DRY LINE TO SURGE
   TO NEAR I35 BY 21Z.  ANY THUNDERSTORMS THAT FORM ACROSS SWRN OK
   WILL INCREASE IN INTENSITY AS CONVECTION APPROACHES MODERATE
   INSTABILITY AXIS WHERE SFC BASED CAPES SHOULD EXCEED 2000J/KG. 
   VERY STRONG DEEP LAYER SHEAR...SFC-6KM ON THE ORDER OF 80KT...WILL
   PROVE FAVORABLE FOR SUPERCELLS.  ALTHOUGH BOUNDARY LAYER MOISTURE
   HAS DRIED SOMEWHAT OVER SERN/ECNTRL OK...RECOVERY FROM THE SOUTH
   SHOULD ALLOW MID 60S DEW POINTS TO RETURN AHEAD OF DRY
   LINE...ENHANCING TORNADIC POTENTIAL AS SUPERCELLS INTENSIFY...A FEW
   POSSIBLY STRONG.  VERY LARGE HAIL APPEARS POSSIBLE ACROSS CNTRL/ERN
   OK WITH MATURING SUPERCELLS EXPECTED TO BECOME MORE EFFICIENT IN
   DAMAGING WINDS AS THEY MOVE NEWD INTO NERN OK/SWRN MO.  DAMAGING
   BOW ECHOES APPEAR POSSIBLE GIVEN STRONG SPEED MAX/SHEAR EXPECTED.
   
   FARTHER SOUTH...ISOLATED SUPERCELLS SHOULD DEVELOP SOUTH ALONG THE
   DRY LINE INTO CENTRAL TX WHERE BOUNDARY LAYER REMAINS
   MOIST/UNSTABLE.  MID LEVEL COOLING WILL PREVENT SIGNIFICANT CAP
   FORMATION...OR THE REMOVAL OF INHIBITION NECESSARY FOR CONVECTIVE
   DEVELOPMENT.  LARGE HAIL AND ISOLATED TORNADOES APPEAR POSSIBLE.
   
   ...UPPER GREAT LAKES...
   
   INCREASING WARM ADVECTION ON NOSE OF LLJ WILL ENHANCE CONVECTIVE
   THREAT FROM NRN MO...NEWD INTO ERN IA/SRN WI.  MUCH OF THIS
   ACTIVITY SHOULD ORIGINATE ABOVE THE BOUNDARY LAYER...PER 12Z
   SOUNDINGS FROM UPSTREAM LOCATIONS.  ELEVATED INSTABILITY APPEARS
   SUFFICIENT FOR LARGE HAIL WITH ANY ORGANIZED MULTI-CELL CLUSTERS OR
   ISOLATED SUPERCELLS.
