   ...THERE IS A SLGT RISK OF SVR TSTMS FL PENINSULA AND COASTAL
   CAROLINAS...
   
   STRONG VORT/UPPER LOW LOWER MS VALLEY 12Z WILL RESPOND TO LARGE
   SCALE TROUGHING UNDERWAY ERN U.S. AND MOVE RAPIDLY EWD TO OFF
   CAROLINA COAST BY LATE TONIGHT.  
   
   FRONTAL ZONE JUST OFF CAROLINA COAST AND ACROSS NERN FL INTO ERN
   GULF OF MEXICO.  PRIMARY SURFACE LOW NOW DEVELOPING ALONG FRONT
   OFFSHORE SRN SC COAST AND WILL DEEPEN NEWD ALLOWING A SMALL WARM
   SECTOR TO MOVE INTO COASTAL NC THIS AFTERNOON.
   
   IN RESPONSE TO SURFACE DEEPENING THE LOW LEVEL FLOW IS VEERING TO
   SWLY ACROSS FL PENINSULA AHEAD OF APPROACHING COLD FRONT AND UPPER
   TROUGH. HOWEVER WITH STRONG MOSTLY UNIDIRECTIONAL SHEAR AND A MOIST
   AND MARGINALLY UNSTABLE AIR MASS WILL MAINTAIN A RISK OF A FEW
   STORMS BRIEFLY BECOMING SEVERE WITH PRIMARY THREAT OF WIND DAMAGE
   UNTIL LATER THIS AFTERNOON. 
   
   FURTHER NE A BETTER CHANCE OF ROTATING STORMS IS POSSIBLE GIVEN THE
   STRONG VEERING SHEAR PROFILES VICINITY OF FRONTAL ZONE.  AGAIN A
   MOIST BUT ONLY MARGINALLY UNSTABLE WARM SECTOR WILL LIMIT SEVERE
   THREAT TO PRIMARILY BRIEF WIND DAMAGE. THERE IS A RISK OF A TORNADO
   OR TWO...PARTICULARLY COASTAL NC WHERE FRONTAL ZONE WILL BE ABLE TO
   SHIFT INLAND THIS AFTERNOON AHEAD OF DEEPENING SURFACE LOW.
