   CONCERNING...SEVERE THUNDERSTORM WATCH 368...
   
   VALID 110640Z - 110715Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 368
   CONTINUES.
   
   WW 368 IS SCHEDULED TO EXPIRE AT 07Z...BUT RECENT RADAR TRENDS
   SUGGEST THE ERN MOST TIER OF AR COUNTIES IN THIS WATCH /PRAIRIE TO
   DESHA/ WILL CONTINUE TO BE AFFECTED BY STRONG TO SEVERE STORMS FROM
   07-08Z.  THEREFORE...LOCAL WFO EXTENSION IS POSSIBLE FOR WW 368.
   
   SATELLITE IMAGERY INDICATED AN MCV ATTENDANT TO THE WELL ORGANIZED
   FORWARD PROPAGATING MCS /WITH A WELL DEFINED COLD POOL/ MOVING
   ACROSS THE LOWER MS VALLEY.  STRONGEST FORCING FOR ASCENT WITH THIS
   MCS IS SPREADING ACROSS SRN/CENTRAL AR WHERE LIGHTNING DATA SHOWS
   THE MORE ACTIVE STORMS...THAN FARTHER S INTO NRN LA WHERE LIGHTNING
   HAS DIMINISHED.  DOWNSTREAM AIR MASS ACROSS SERN AR/WRN MS REMAINS
   MODERATELY UNSTABLE SUGGESTING THIS BOW WILL PROGRESS ENEWD WITH A
   CONTINUED THREAT FOR DAMAGING WINDS.
