SCATTERED INTENSE CONVECTIVE DEVELOPMENT IS ONGOING FROM THE LEE OF
THE SOUTHERN APPALACHIANS INTO THE SOUTH CAROLINA PIEDMONT.  THIS IS
GENERALLY ALONG/SOUTH OF SURFACE FRONTAL ZONE EXTENDING FROM UPSTATE
SOUTH CAROLINA THROUGH AREAS NEAR/NORTH OF COLUMBIA INTO THE
VICINITY OF MYRTLE BEACH.  WEAK SURFACE LOW NEAR COLUMBIA IS
PROVIDING A FOCUS FOR STRONGER LOW-LEVEL CONVERGENCE...AND
CONSOLIDATION OF ACTIVITY INTO A MORE SUBSTANTIAL CONVECTIVE CLUSTER
APPEARS POSSIBLE ACROSS THE CENTRAL SOUTH CAROLINA PIEDMONT THROUGH
21Z.

OBJECTIVE ANALYSIS INDICATES MIXED LAYER CAPE IN WARM SECTOR OF LOW
IS ON THE ORDER OF 2000 J/KG.  AS CONVECTION BEGINS TO INGEST THIS
AIR MASS...INTENSIFYING UPDRAFTS IN SUFFICIENTLY SHEARED ENVIRONMENT
FOR SUPERCELLS COULD BECOME SUPPORTIVE OF ISOLATED VERY LARGE HAIL
NEAR COLUMBIA. THROUGH LOW-LEVEL HODOGRAPHS ARE GENERALLY
SMALL/WEAK...AN ISOLATED TORNADO IS POSSIBLE...BEFORE DAMAGING WIND
THREAT INCREASES TOWARD THE COASTAL PLAIN LATER THIS AFTERNOON.
