   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 337
   CONTINUES.
   
   LONG-LIVED LINEAR/TRAILING STRATIFORM MCS WITH A HISTORY OF WIND
   DAMAGE ACROSS ERN TX/WRN LA WILL CONTINUE TO MARCH E/SEWD THROUGH
   THE ERN HALF OF WW 337 OVER THE NEXT FEW HOURS. IF OVERALL INTENSITY
   APPEARS TO BE MAINTAINED...A DOWNSTREAM WW WILL LIKELY BE ISSUED
   ACROSS ERN LA/SWRN MS WITHIN THE HOUR.
   
   AS OF 2005Z...THE LEADING EDGE OF THE LINEAR MCS WAS ROUGHLY FROM 40
   W MLU SWD TO ESF ARCING SWWD TO NEAR LCH. OVERALL RADAR REFLECTIVITY
   TRENDS HAVE SHOWN A DOWNWARD/INCREASINGLY DISORGANIZED TREND OVER
   THE PAST HOUR...WITH CORRESPONDING WARMING OF CONVECTIVE CLOUD TOPS
   ON IR IMAGERY. THIS APPEARS TO CORRELATE WITH THE LINE MOVING E OF
   THE RICHEST LOW-LEVEL THETA-E AXIS. STILL...WITH TEMPERATURES IN THE
   UPPER 80S AND DEW POINTS IN THE MID TO UPPER 60S AHEAD OF THE
   LINE...CONVECTIVE INTENSITY MAY BE ABLE TO MAINTAIN ITSELF IN
   POSSIBLY MORE DISORGANIZED LINE SEGMENTS. DAMAGING WINDS WILL LIKELY
   REMAIN THE MAIN THREAT.
