   AREAS AFFECTED...ECNTRL AND SERN LA THROUGH SRN AND CNTRL MS
   
   CONCERNING...TORNADO WATCH 32...
   
   VALID 101959Z - 102130Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 32 CONTINUES.
   
   SUMMARY...GREATEST TORNADO THREAT NOW THROUGH 22Z APPEARS TO BE
   EVOLVING FROM ACROSS SRN MS. OTHERWISE...THREAT FOR DAMAGING WIND
   AND TORNADOES WILL PERSIST OVER THE REMAINDER OF WW 32 FROM ECNTRL
   AND SERN LA INTO SRN AND SCNTRL MS.
   
   DISCUSSION...NUMEROUS DISCRETE STORMS ARE DEVELOPING WITHIN ZONE OF
   WARM ADVECTION AND ISENTROPIC ASCENT ALONG LLJ AXIS FROM SERN LA
   INTO SRN MS. STORMS NEAR AND SOUTH OF WARM FRONT ARE SURFACE BASED
   AND HAVE ACCESS TO MOIST AND UNSTABLE LOW LEVEL INFLOW WHERE
   DEWPOINTS ARE IN THE UPPER 60S AND TEMPERATURES IN THE LOW 70S. VWP
   DATA SHOW VERY LARGE HODOGRAPHS ASSOCIATED WITH THE LLJ WITH 400-500
   M2/S2 STORM RELATIVE HELICITY. THE DISCRETE STORMS IN SRN MS
   CONTINUE TO BECOME BETTER ORGANIZED AS SUPERCELLS AND TORNADOES
   APPEAR LIKELY WITH ACTIVITY DEVELOPING NEAR AND SOUTH OF THE WARM
   FRONT. THIS BOUNDARY WILL CONTINUE LIFTING SLOWLY NWD DURING THE
   REMAINDER OF THE AFTERNOON SUGGESTING THE ENHANCED TORNADO THREAT
   WILL EXPAND NWD AND EWD WITH TIME. OTHER STORMS FARTHER WEST WITHIN
   THE LINE WILL ALSO POSE A THREAT FOR DAMAGING WIND AND TORNADOES.
