SPC MESOSCALE DISCUSSION 1112 FOR NRN/WRN OK AND EXTREME SERN KS
   CONCERNING...SEVERE THUNDERSTORM WATCH 422...
   
   VALID 130354Z - 130500Z
   
   LINE OF STRONG/SEVERE STORMS FROM 30 ESE BVO TO 25 WSW OKC IS
   MOVING ESEWD AT 30 TO 40 KT. WINDS 50 TO 65 MPH ARE MOST LIKELY
   WITH THE LINE...WITH THE GREATEST THREAT OF SEVERE WINDS FROM 40
   WSW TUL TO OKC WHERE MESOLOW EARLIER ACCELERATED LINE SEWD.
   HOWEVER...AS THE LINE CONTINUES TO MOVE SEWD AND INSTABILITY 
   SLOWLY WEAKENS...WIND GUSTS MAY DECREASE MOSTLY BELOW SEVERE
   CRITERIA AND WW NOT ANTICIPATED SE OF CURRENT WATCH. 
   
   WRN PORTION OF LINE ACROSS WRN OK WEAKENED EARLIER...LIKELY DUE TO
   HEAT BURSTS PRODUCED FROM ANVIL OUT OF DISSIPATING CONVECTION THAT
   MOVED OUT THE OF TX PANHANDLE. SOME STORMS MAY REDEVELOP IN WRN OK
   AS LINE MOVES INTO RICHER BOUNDARY LAYER MOISTURE...BUT STORMS
   SHOULD ONLY PRODUCE MARGINAL SEVERE WEATHER.
