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.
