   DISCUSSION...TSTMS HAVE INTENSIFIED ALONG THE LA/MS BORDER FROM NEAR
   MCB TO HDC DURING THE PAST HOUR IN THE VICINITY OF A COLD FRONT THAT
   EXTENDS FROM E OF JAN TO THE LA COAST NR PTN. THESE TSTMS ARE
   LOCATED IN AN ENVIRONMENT WITH VEERING 0-3 KM WINDS AND DEEP LAYER
   SHEAR LARGELY PARALLEL TO THE FRONTAL ZONE...AND HAVE DEVELOPED A
   LINEAR STRUCTURE WITH OCCASIONAL EMBEDDED BOWING SEGMENTS. THE
   POTENTIAL FOR DAMAGING WINDS...AND POSSIBLY A BRIEF TORNADO...WILL
   EXIST THROUGH THE REMAINDER OF THIS AFTERNOON. THE SVR THREAT IS
   EXPECTED TO REMAIN ISOLATED DUE TO WIDESPREAD CLOUD COVER AND POOR
   LAPSE RATES...AND A WW IS NOT CURRENTLY ANTICIPATED.
