AREAS AFFECTED...CNTRL/ERN AL...NRN/CNTRL GA...WRN SC...WRN NC

CONCERNING...SEVERE THUNDERSTORM POTENTIAL

VALID 031010Z - 031215Z

HIGHEST PROBABILITY FOR LARGE HAIL...DAMAGING WINDS...AND PERHAPS A
TORNADO OR TWO WILL EXIST ACROSS ECNTRL AL NEWD ACROSS CNTRL/NRN GA
THROUGH MID-MORNING.

A STRONG MID-LEVEL JET STREAK CONTINUED TO TRANSLATE EWD ACROSS THE
MID-SOUTH AT DAYBREAK...WITH THE STRONGEST LARGE SCALE ASCENT
SPREADING INTO THE SRN APPALACHIANS.  THE TSTMS THAT GREW UPSCALE
INTO A LINEAR MCS OVERNIGHT...CONTINUE TO MOVE ESEWD ACROSS THE SRN
APPALACHIANS AT 10Z.

DESPITE STRONG LOW/MID-LEVEL SHEAR...COLD OUTFLOW HAS TENDED TO
DOMINATE THE STORMS THROUGH THE MORNING...LESSENING THE RISK FOR
TORNADOES.  BUT...PLUME OF STEEP MID-TROPOSPHERIC LAPSE RATES
SPREADING EWD FROM THE HIGH PLAINS WAS SUPPORTING LARGE HAIL.

AS THE MID-LEVEL JET STREAK DEVELOPS EWD THROUGH THE MID-MORNING
HOURS...TSTMS SHOULD INTENSIFY ACROSS NRN/CNTRL GA AND MOVE EWD INTO
PARTS OF SC.  INCREASED BOUNDARY LAYER HEATING WILL BOOST BUOYANCY
AND TSTMS MAY BEGIN TO POSE MORE OF A DAMAGING WIND/TORNADO THREATS
IN A FEW HOURS.  STRONG WSWLY UNIDIRECTIONAL FLOW REGIME WILL
ENCOURAGE BOW ECHOES AND SUPERCELLS.

UPSTREAM...TSTMS WILL TEND TO BACKBUILD INTO PARTS OF AL INTO THE
STEEPER MID-LEVEL LAPSE RATES. THESE STORMS WILL TEND TO BE MORE OF
A LARGE HAIL THREAT.
