   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 32 CONTINUES.
   
   SUMMARY...A SUPERCELL TORNADO RISK WILL CONTINUE OVER SRN MS AND
   ADJACENT PORTIONS OF SRN LA THROUGH THE LATE EVENING.  A REPLACEMENT
   TORNADO WATCH WILL BE COORDINATED WITHIN THE NEXT 30 MINUTES OR SO.
   
   DISCUSSION...THE SWD STALLING OF AN EWD MOVING MCS ACROSS MS AND AL
   HAS CONFINED BUT LEFT A MOIST/MARGINALLY UNSTABLE WARM SECTOR
   /250-1000 J/KG MLCAPE/ UNDISTURBED OVER SRN LA AND SRN MS.  SEVERAL
   LOW LEVEL CONFLUENCE BANDS HAVE SERVED AS PREFERRED FOCI FOR
   CONTINUED STORM GENERATION THE PAST FEW HOURS AS THE BOUNDARY LAYER
   HAS HEATED INTO THE MID 70S NEAR THE I-10 CORRIDOR.  INPUTTING THE
   STORM MOTION /240 AT 40 KT/ FOR THE LAMAR COUNTY MS CONFIRMED
   TORNADIC STORM IS YIELDING AROUND 200 M2/S2 0-1 SRH WITHIN A
   FAVORABLE DEEP LAYER WIND PROFILE FOR SUPERCELLS.  ALTHOUGH THE BELT
   OF H85 FLOW IS EXPECTED TO SLIGHTLY WEAKEN OVER THE NEXT 6
   HRS...SUFFICIENT LOW LEVEL VERTICAL SHEAR WITHIN A MOIST ENVIRONMENT
   /CHARACTERIZED BY MID-UPPER 60S DEWPOINTS/ SHOULD CONTINUE TO
   SUPPORT AN INTERMITTENT ISOLD RISK FOR SUPERCELL TORNADOES INTO THE
   LATE EVENING HOURS.
