   ...LOWER MS RIVER VALLEY INTO THE CENTRAL GULF COAST...
   MORNING AND FORECAST SOUNDINGS INDICATE MID LEVEL INVERSION/CAP NEAR
   700 MB AHEAD OF SURFACE COLD FRONT NOW MOVING INTO THE LOWER MS
   RIVER VALLEY.  DESPITE THIS...LOWER 70F SURFACE DEW POINTS ARE IN
   PLACE AHEAD OF THE FRONT WHICH ARE SUPPORTING MARGINAL SURFACE BASED
   INSTABILITY ATTM.  EXPECT AN AXIS OF MARGINAL SBCAPE WILL CONTINUE
   AHEAD OF EWD MOVING COLD FRONT TODAY...WITH SUFFICIENT ASCENT NEAR
   THE FRONT POSSIBLY BOOSTING BOUNDARY LAYER PARCELS THROUGH H7
   INVERSION / AS IS NOW OCCURRING OVER S-CENTRAL LA/.  THIS IS MOST
   LIKELY TO OCCUR WITHIN RICHER GULF MOISTURE NEAR THE CENTRAL GULF
   COAST FROM SERN LA INTO FAR SRN MS/AL. STRENGTH OF LOW AND DEEP
   LAYER SHEAR WILL REMAIN MORE THAN SUFFICIENT FOR ROTATING
   UPDRAFTS...THOUGH WEAK LAPSE RATES AND LIMITED INSTABILITY WILL
   DIMINISH OVERALL SEVERE THREAT.  STILL...GIVEN LOW LCLS AND THE
   POTENTIAL FOR AN ISOLATED STORM TO ROOT INTO A MOIST BOUNDARY
   LAYER...AT LEAST LOW PROBABILITIES OF DAMAGING WINDS AND/OR A
   TORNADO ARE WARRANTED.
