   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 123...125...CONTINUES.
   
   SEVERE/TORNADO THREAT CONTINUES ACROSS THE REMAINING PORTIONS OF WW
   123 AND EWD INTO WW 125 -- ACROSS MUCH OF AR AND ADJACENT SRN MO.
   
   A BROKEN BAND OF THUNDERSTORMS -- THE STRONGEST OF WHICH EXTEND FROM
   SWRN MO SWD INTO SWRN AR/NERN TX -- CONTINUE MOVING QUICKLY ENEWD. 
   SEVERAL SUPERCELLS ARE ONGOING WITHIN THIS BAND -- PARTICULARLY FROM
   NWRN AR SWD...WITH A DAMAGING TORNADO CONFIRMED IN THE TOWN OF MENA
   AR WITHIN THE PAST HOUR.
   
   THOUGH INSTABILITY DECREASES WITH EWD EXTENT ACROSS AR...STRONG
   LOW-LEVEL FORCING SHOULD SUSTAIN VIGOROUS STORMS FOR SEVERAL HOURS. 
   AREA VWP/PROFILER DATA CONTINUE TO REVEAL STRONG 0-1 KM
   VEERING/SHEAR SUPPORTIVE OF ROTATION -- SUGGESTING THAT ADDITIONAL
   TORNADOES REMAIN POSSIBLE...ALONG WITH THE THREAT DAMAGING WINDS AND
   HAIL.
