   ...SYNOPSIS...
   BROAD BELT OF NWLY MID-LEVEL FLOW EXISTS ACROSS THE CONUS ATTM W OF
   WEAK / NEGATIVELY-TILTED TROUGH EXTENDING FROM ONTARIO SEWD TO THE
   MID-ATLANTIC COAST.  WEAK SHORT-WAVE TROUGH NOW MOVING ACROSS OK AND
   ASSOCIATED LOW-LEVEL JET WILL SUPPORT CONTINUED CONVECTIVE
   DEVELOPMENT INTO THE OVERNIGHT HOURS.
   
   ...FAR SERN KS / ERN OK / FAR NERN TX INTO SWRN MO AND WRN AR...
   THUNDERSTORMS CONTINUE TO DEVELOP ACROSS CENTRAL AND NERN OK AHEAD
   OF WEAK COLD FRONT WHICH CURRENTLY EXTENDS FROM NEAR EMP SWWD TO
   NEAR SPS ATTM. DAYTIME HEATING HAS RESULTING IN 500 TO 1000 J/KG
   MEAN-LAYER CAPE ACROSS THE ERN HALF OF OK...WHERE MID 50S DEWPOINTS
   HAVE ADVECTED NWD IN NARROW AXIS AHEAD OF FRONT.  
   
   MODERATE / VEERING WINDS WITH HEIGHT ARE SUPPORTIVE OF
   SUPERCELLS...WITH AROUND 50 KTS SURFACE TO 6 KM SHEAR NOTED ON AREA
   PROFILERS.  THIS SUPPORTS RECENT RADAR INDICATIONS OF DEVIANT STORM
   MOTIONS AND A STORM SPLIT JUST E OF TUL.

   FAIRLY HIGH-BASED...MAIN SEVERE THREATS WILL BE LARGE HAIL AND
   LOCALLY DAMAGING WINDS.  OVERNIGHT...SEVERE THREAT SHOULD SLOWLY
   DECREASE WITH TIME AS BOUNDARY LAYER STABILIZES AND STORMS MOVE EWD
   INTO AR WHERE DRIER / LESS UNSTABLE AIRMASS EXISTS.
