   VALID 191755Z - 191900Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 417
   CONTINUES.
   
   THREAT FOR DAMAGING WINDS INCREASING ACROSS CENTRAL/SRN MS AND
   POTENTIALLY INTO FAR NERN LA AS BOW ECHO CONTINUES TO MOVE SWD AT 35
   KT.  AT 1745Z...REGIONAL RADARS INDICATED A WELL ESTABLISHED COLD
   POOL OVER NRN MS WITH THE ASSOCIATED BOW ECHO EXTENDING FROM CHOCTAW
   COUNTY WWD THROUGH HOLMES COUNTY TO SUNFLOWER COUNTY.  AIR MASS
   ALONG/S OF THIS BOW ECHO HAS BECOME VERY UNSTABLE WITH MLCAPE VALUES
   RISING TO 2000-3000 J/KG.  GIVEN WELL ESTABLISHED COLD POOL AND
   DEGREE OF DOWNSTREAM INSTABILITY...THIS BOW WILL CONTINUE TO MOVE
   SWD AND MAY INCREASE IN FORWARD SPEED.  CURRENT TRENDS SUGGEST
   DAMAGING WINDS WILL LIKELY REACH THE JACKSON MS AREA BY 19Z.
