   VALID 251823Z - 251930Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 693
   CONTINUES.
   
   SUMMARY...SEVERE CONVECTIVE WIND GUSTS AND LARGE HAIL WILL CONTINUE
   AS THE PRIMARY THREATS ACROSS THE WW AREA AS A QLCS PROGRESSES EWD.
   AREAS IN THE WAKE OF THE QLCS MAY BE CLEARED FROM THE WW.
   MEANWHILE...SUFFICIENT SURFACE-BASED DESTABILIZATION HAS OCCURRED
   ACROSS THE SRN PORTION OF THE WW SUCH THAT A TORNADO THREAT EXISTS
   /REF MD 2210/. A TORNADO WW WILL BE NEEDED DOWNSTREAM ACROSS
   PORTIONS OF MS.
   
   DISCUSSION...A QLCS HAS FORMED RAPIDLY IN RESPONSE TO STRONG FORCING
   FOR ASCENT...WITH THE LEADING EDGE CLEARLY DEMARCATED ON 18Z WV
   IMAGERY ACROSS E TX. AS THE WARM SECTOR CONTINUES TO EXPAND AND
   CONVECTION BECOMES NEAR SURFACE-BASED...A COINCIDENT STRENGTHENING
   OF DEEP LAYER WINDS WILL AID IN INCREASING DAMAGING WIND GUSTS
   ACROSS THE WW AREA. RECENT SURFACE OBSERVATIONS ACROSS NRN LA
   REFLECT GUSTS TO NEAR 50 MPH WITH THE PRIMARY LINE OF CONVECTION.
   MEANWHILE...TORNADIC POTENTIAL IS INCREASING ACROSS SRN PORTIONS OF
   THE WW /REF MCD 2210/...WITH A STRONG COUPLET RECENTLY NOTED OVER
   VERNON PARISH JUST S OF SVR WW 693.
