...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
WEDNESDAY.

...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.
