   ...SOUTH CENTRAL U.S...
   LOW AMPLITUDE MID/UPPER TROUGH MIGRATING INTO THE CENTRAL PLAINS
   WILL CONTINUE EASTWARD INTO THE MIDDLE MISSISSIPPI VALLEY
   OVERNIGHT.  STRONGER BELT OF FLOW ON ITS SOUTHERN PERIPHERY IS
   ENHANCING VERTICAL SHEAR PROFILES ACROSS OKLAHOMA AND ARKANSAS...
   WHERE INTENSE CONVECTIVE DEVELOPMENT MAY PERSIST THROUGH THE NIGHT.
   
   SCATTERED SEVERE THUNDERSTORMS ARE ONGOING ACROSS THE SOUTHERN
   PLAINS...WHERE INSTABILITY IS  MAXIMIZED ALONG/EAST OF LOW-LEVEL
   THERMAL RIDGE AXIS...WHICH CURVES FROM EASTERN OKLAHOMA INTO
   CENTRAL TEXAS.  WITH ONSET OF RADIATIONAL COOLING...INTENSE
   CONVECTION IS EXPECTED TO SLOWLY WEAKEN THROUGH THE MID/LATE
   EVENING HOURS ACROSS PARTS OF CENTRAL TEXAS...WHERE MID-LEVEL CAP
   SHOULD EVENTUALLY SUPPRESS NEW ACTIVITY ALONG OUTFLOWS.
   
   HOWEVER...IN ZONE OF ENHANCED LOW-LEVEL WARM ADVECTION ON
   NORTHEASTERN PERIPHERY OF CAPPED SOUTHERN PLAINS ENVIRONMENT...
   ONGOING CONVECTION ACROSS EASTERN OKLAHOMA WILL LIKELY DEVELOP EAST
   SOUTHEASTWARD ACROSS ARKANSAS.  CONVECTIVELY ENHANCED LOW-LEVEL
   SURFACE BOUNDARY EXTENDING FROM THE FORT SMITH VICINITY INTO THE
   LITTLE ROCK AND PINE BLUFF AREAS MAY PROVIDE FOCUS FOR MOST INTENSE
   STORMS.  ISOLATED TORNADOES ARE POSSIBLE WITH SUPERCELLS NEAR/EAST
   OF FORT SMITH DURING THE NEXT COUPLE OF HOURS...BUT PRIMARY THREAT
   BY LATE EVENING IS EXPECTED TO BE LARGE HAIL/GUSTY WINDS AS
   SOMEWHAT LARGER MESOSCALE CONVECTIVE SYSTEM EVOLVES IN ENVIRONMENT
   WITH CAPE OF 1500 TO 3000 J/KG.
   
   ...EASTERN U.S...
   WITH LOSS OF SURFACE HEATING...SEVERE THREAT WILL CONTINUE TO
   SLOWLY DIMINISH WITH CONVECTIVE ACTIVITY DEVELOPING ALONG/AHEAD OF
   OUTFLOW BOUNDARY SURGING TOWARD THE APPALACHIANS.  SEVERE THREAT
   HAS ALSO GENERALLY DIMINISHED ALONG/AHEAD OF SURFACE FRONT CURVING
   FROM THE ST. LAWRENCE VALLEY INTO THE LOWER GREAT LAKES REGION. 
   HOWEVER...CLUSTER OF STORMS CONTINUES TO SLOWLY ORGANIZE IN
   ASSOCIATION WITH MID-LEVEL CYCLONIC VORTICITY CENTER MIGRATING OUT
   OF CENTRAL INDIANA INTO NORTHWEST OHIO.  THIS ACTIVITY LIKELY WILL
   PERSIST TONIGHT...SPREADING ACROSS NORTHERN OHIO INTO PARTS OF
   SOUTHERN NEW YORK/WESTERN AND CENTRAL PENNSYLVANIA...WHERE 30+ KT
   MEAN FLOW ON SOUTHERN FRINGE OF WESTERLIES SUPPORTS A RISK OF
   DAMAGING WIND GUSTS.
