   VALID 291200Z - 301200Z

   ...THERE IS A MRGL RISK OF SVR TSTMS ACROSS PARTS OF THE SERN
   U.S....

   ...SUMMARY...
   SCATTERED STRONG THUNDERSTORMS...A FEW POSSIBLY SEVERE...SHOULD
   DEVELOP ACROSS THE SOUTHEASTERN U.S. AHEAD OF A FRONTAL ZONE

   ...SERN U.S...

   LATEST SHORT-RANGE MODEL GUIDANCE CONTINUES TO SUGGEST MID-LEVEL
   SPEED MAX WILL TRANSLATE ALONG THE GULF COAST...OFF THE NRN FL COAST
   BY 30/00Z.  SFC LOW ASSOCIATED WITH THIS FEATURE SHOULD TRACK INLAND
   ACROSS THE FL PANHANDLE BEFORE MOVING OFF THE GA COAST BY MID
   AFTERNOON.  CONSIDERABLE AMOUNT OF CONVECTION IS EXPECTED TO DEVELOP
   AHEAD OF COLD FRONT AND EXTENSIVE CLOUDS/PRECIP MAY LIMIT BUOYANCY
   ACROSS THE WARM SECTOR WITHIN A STRONGLY SHEARED ENVIRONMENT.  GIVEN
   THE QUESTIONABLE BUOYANCY HAVE OPTED TO INTRODUCE A CATEGORY 1
   SEVERE THREAT FOR THE POSSIBILITY OF A FEW STRONG/SEVERE
   THUNDERSTORMS.  SHEAR PROFILES WILL SUPPORT ROTATING UPDRAFTS AND
   SUPERCELLS CAN NOT BE RULED OUT IF SUFFICIENT INSTABILITY CAN
   MATERIALIZE AHEAD OF COLD FRONT.  WILL MONITOR THIS REGION FOR
   POSSIBLE UPGRADE IN LATER OUTLOOKS.
