   DAY 3 CONVECTIVE OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0222 AM CDT THU MAR 13 2008
   
   VALID 151200Z - 161200Z
   
   ...THERE IS A SLGT RISK OF SVR TSTMS FROM WRN TN/KY INTO THE
   CAROLINAS...
   
   ...TN VALLEY TO THE CAROLINA COAST...
   
   STRONG SPEED MAX WILL EJECT ACROSS THE TN VALLEY/NRN GULF STATES
   INTO THE CAROLINAS DAY3 WITH WEAK HEIGHT RISES EXPECTED ACROSS THE
   REGION.  EARLY IN THE PERIOD IT APPEARS WARM ADVECTION WILL FOCUS
   THUNDERSTORM CLUSTERS...A FEW SEVERE...JUST AHEAD OF SFC LOW ACROSS
   WRN TN/KY.  WITH SWLY LLJ EXPECTED TO SHIFT EAST DURING THE DAY IT
   SEEMS REASONABLE TO EXPECT THIS ACTIVITY TO MOVE/DEVELOP EWD ALONG
   WARM FRONT INTO THE CAROLINAS.  GIVEN THE RELATIVELY WEAK BOUNDARY
   LAYER CONVERGENCE ACROSS THE WARM SECTOR THUNDERSTORMS WILL LIKELY
   BE CONCENTRATED ALONG THE E-W BOUNDARY.  DURING PEAK HEATING A FEW
   THUNDERSTORMS SHOULD DEVELOP SOUTH OF THE WARM FRONT AHEAD OF
   ADVANCING COLD FRONT ACROSS NRN MS GA INTO SC.  WITH DEW POINTS
   RISING INTO THE 60S MODEST INSTABILITY AND SHEAR WILL SUPPORT THE
   THREAT OF ISOLATED SUPERCELLS.  BY EARLY EVENING GREATEST SEVERE
   THREAT WILL SHIFT INTO THE CAROLINAS AS EXIT REGION OF UPPER SPEED
   MAX BEGINS TO SHIFT OFFSHORE.
