   VALID 062014Z - 062215Z
   
   THUNDERSTORMS MAY INCREASE ACROSS PARTS OF WRN-SWRN KS AND POSSIBLY
   SEWD INTO NWRN OK INTO THE EVENING. LARGE HAIL AND ISOLATED STRONG
   WIND GUSTS APPEAR TO BE THE MAIN THREATS. TRENDS WILL CONTINUE TO BE
   MONITORED FOR A POSSIBLE WW.
   
   DRYLINE EXTENDS FROM EXTREME ERN CO SWWD THROUGH ERN NM. A WEAK WARM
   FRONT EXTENDS FROM NW OK NWWD THROUGH SWRN KS. STEEP 7.5-8 C/KM
   850-500 MB MID LEVEL LAPSE RATES HAVE SPREAD EAST OVER THE MOIST
   AXIS WHERE DEWPOINTS ARE IN THE UPPER 50S. THIS ALONG WITH STRONG
   DIABATIC HEATING HAVE CONTRIBUTED TO MLCAPE FROM 1500 TO 2000 J/KG
   EAST OF THE DRYLINE ACROSS WRN KS THROUGH NWRN OK. HIGH BASED STORMS
   CONTINUE DEVELOPING IN THE MORE DEEPLY MIXED AIR JUST WEST OF THE
   DRYLINE...AND THIS ACTIVITY WILL HAVE THE POTENTIAL TO INTENSIFY AS
   IT MOVES EAST AND INTERCEPTS THE MOIST AXIS. MODEST SWLY MID LEVEL
   FLOW ASSOCIATED WITH WEAK UPPER RIDGING ALOFT AND VEERED SWLY LOW
   LEVEL WINDS ARE RESULTING IN UNIDIRECTIONAL WIND PROFILES WITH BULK
   SHEAR MOSTLY SUPPORTIVE OF MULTICELLS. SOME MARGINAL SUPERCELL
   STRUCTURES MAY ALSO BE POSSIBLE.
   
   LOW LEVEL CONVERGENCE ALONG DRYLINE AND WARM FRONT IS SOMEWHAT
   LIMITED...AND THE WEAK LOW LEVEL FOCUS AND MODEST VERTICAL SHEAR
   APPEAR TO BE THE MAIN SHORT TERM LIMITING FACTORS. HOWEVER...THE NRN
   PERIPHERY OF UPPER RIDGE WILL LIKELY BE SUPPRESSED BY A NRN STREAM
   IMPULSE. THIS ALONG WITH INTENSIFYING SLY LOW LEVEL JET WILL ENHANCE
   VERTICAL SHEAR THIS EVENING WITH AN INCREASING THREAT FOR ORGANIZED
   STORMS INCLUDING SUPERCELLS.
