AREAS AFFECTED...NERN GA INTO WRN SC

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 261504Z - 261630Z

TRENDS ARE BEING MONITORED FOR INCREASING SEVERE THREAT.  A WW
LIKELY WILL BE NEEDED IN THE LEE OF THE SOUTHERN APPALACHIANS...
PERHAPS BY EARLY AFTERNOON.

INITIATION OF NEW CONVECTIVE DEVELOPMENT IS ALREADY UNDERWAY ACROSS
THE HIGHER TERRAIN OF WESTERN SOUTH CAROLINA.  THIS IS PROBABLY
LARGELY DRIVEN BY OROGRAPHIC FORCING...BUT STRENGTHENING DIVERGENCE
ALOFT...AHEAD OF SHORT WAVE TROUGH DIGGING FROM THE MIDDLE
MISSISSIPPI VALLEY INTO THE TENNESSEE VALLEY...WILL COME OF
INCREASING INFLUENCE THROUGH MID DAY.  STORMS ARE EXPECTED TO
INCREASE IN COVERAGE TO THE LEE OF THE APPALACHIANS THROUGH
16-18Z...ACROSS MUCH OF NORTHEAST GEORGIA INTO WESTERN SOUTH
CAROLINA...WHERE MOIST BOUNDARY LAYER WILL CONTINUE TO DESTABILIZE
WITH INSOLATION.  MOST UNSTABLE CAPE IS ALREADY IN EXCESS OF 1500
J/KG...IN FAVORABLY SHEARED REGIME BENEATH 40+ KT WESTERLY MID-LEVEL
FLOW...WHICH SHOULD BE SUFFICIENT FOR AT LEAST BRIEF MID-LEVEL
UPDRAFT ROTATION.  LARGE HAIL IS EXPECTED TO BE PRIMARY SEVERE
THREAT THOUGH EARLY AFTERNOON...BEFORE DAMAGING WIND POTENTIAL
INCREASES TO THE EAST SOUTHEAST LATER ON.
