   ...AN OUTBREAK OF SEVERE THUNDERSTORMS AND TORNADOES IS STILL
   ANTICIPATED ACROSS PORTIONS OF THE EAST-CENTRAL PLAINS TO THE
   MID MS RIVER VALLEY...
   
   SURFACE CYCLONE WILL CONTINUE TO DEEPEN INTO SERN NEB..AS DRY LINE
   FRONT SURGES EWD ACROSS CENTRAL KS/OK THIS AFTERNOON.  EARLIER MCS
   OVER MO HAS REINFORCED WARM FRONT FROM NEAR THE NERN KS/SERN NEB
   BORDER SSEWD INTO CENTRAL AR...WHICH THEN EXTENDS MORE ESEWD INTO
   CENTRAL MS/SRN AL.  THOUGH STABILIZING EFFECTS FROM EARLIER
   CONVECTION WILL HINDER NWD MOTION FOR A WHILE...STRONG PRESSURE
   FALLS AND IMPRESSIVE LOW LEVEL WAA WILL AID IN QUICKLY LIFTING THIS
   BOUNDARY NEWD ACROSS MUCH OF AR AND INTO NRN MO/SWRN IA BY THE
   MID/LATE AFTERNOON.  IN ITS WAKE...A RAPIDLY DESTABILIZING AIR MASS
   WILL OCCUR AHEAD OF APPROACHING DRY LINE WHERE MLCAPES WILL EXCEED
   2500 J/KG.  MOSTLY LIKELY AREA OF MOIST-CONVECTIVE INITIATION IS
   EXPECTED FROM NEAR THE SURFACE LOW SWD ACROSS ERN KS AND POSSIBLY
   NERN OK FROM 18Z-20Z...WHERE STRONGEST LIFT NORTH OF MID/UPPER
   LEVEL SPEED MAX WILL OVERSPREAD INCREASING CONVERGENCE AT THE
   SURFACE.  STORMS WILL RAPIDLY BECOME SEVERE IN THE FORM OF DISCRETE
   SUPERCELLS.  DEVELOPMENT IS EXPECTED TO OCCUR ACROSS ERN OK AND
   INTO NRN/ERN TX...AS WELL AS INTO NRN LA/AR AND POSSIBLY NRN MS/WRN
   TN THROUGH THE LATE AFTERNOON/EVENING AS UPPER JET BECOMES MORE WLY
   AND STRONG HEATING ERODES CAP ACROSS THE WARM SECTOR.  THIS
   ACTIVITY WILL ALSO LIKELY REMAIN SUPERCELLULAR.  THE THREATS OF
   TORNADOES... INCLUDING LONG-LIVED TORNADIC SUPERCELLS...AND VERY
   LARGE HAIL WILL OCCUR ACROSS THE ENTIRE REGION.  VERY POTENT
   COMBINATION OF STRONG INSTABILITY...LOW AND DEEP LAYER SHEAR AND
   DEEP LIFTING INDICATE SIGNIFICANT TORNADOES ARE LIKELY FROM THE MID
   AFTERNOON UNTIL WELL AFTER DARK.
   
   ACTIVITY WILL LIKELY EVOLVE INTO A SQUALL LINE OR BROKEN LINE OF
   SUPERCELLS/LEWPS DURING THE EVENING FROM ERN IA ACROSS THE MID MS
   RIVER VALLEY AND INTO THE ARKLATEX.  THIS ACTIVITY WILL LIKELY
   SPREAD EWD WELL AWAY FROM SURFACE FRONT...AND OVERSPREAD MUCH OF
   THE TN/OH RIVER VALLEYS AS WELL AS TOWARDS THE SRN GREAT LAKES
   THROUGH THE NIGHT.
