   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 
   
   VALID 090043Z - 090145Z
   
   BAND OF STORMS FROM SWRN THROUGH S-CNTRL AR HAS RECENTLY SHOWN AN
   INCREASE IN INTENSITY. CONCERN IS THAT SEVERE THREAT MAY PERSIST
   ANOTHER FEW HOURS AND EXTEND INTO CNTRL AND ERN AR. AREA IS BEING
   MONITORED FOR A TORNADO WATCH.
   
   STORMS JUST WEST OF LITTLE ROCK HAVE SHOWN AN INCREASE IN INTENSITY.
   STORMS WILL BE MOVING EWD INTO A REGION WHERE THE LLJ WILL UNDERGO
   AN INCREASE TONIGHT RESULTING IN LARGE HODOGRAPHS. WEAK INSTABILITY
   COULD SERVE AS A POTENTIAL LIMITING FACTOR...BUT MAY NOT DECREASE
   FAST ENOUGH TO RULE OUT A THREAT OF ISOLATED TORNADOES...ESPECIALLY
   GIVEN PERSISTENT THETA-E ADVECTION ALONG THE LLJ.
