VALID 091710Z - 091845Z

A WW IS NOT ANTICIPATED.  MARGINAL SEVERE HAIL AND DOWNBURSTS ARE
EXPECTED TO REMAIN RATHER LOCALIZED WITH PULSING STORMS...BUT TRENDS
WILL CONTINUE TO BE MONITORED FOR THE POSSIBILITY OF A MORE
ORGANIZED SEVERE WEATHER THREAT.

WEAK UPSLOPE FLOW AND OROGRAPHIC LIFT ACROSS THE CUMBERLAND PLATEAU
AND SOUTHERN APPALACHIANS HAVE CONTRIBUTED TO THE DEVELOPMENT OF
SCATTERED VIGOROUS THUNDERSTORMS AS INSOLATION WEAKENED INHIBITION
FOR BOUNDARY LAYER PARCELS.  MIXED LAYER CAPE IS SIZABLE...IN EXCESS
OF 2000 J/KG...ACROSS MUCH OF THE REGION...AND AS LOW-LEVEL LAPSE
RATES CONTINUE TO STEEPEN...THERMODYNAMIC PROFILES WILL LIKELY BE
FAVORABLE FOR LOCALIZED DOWNBURSTS...PERHAPS MARGINALLY SEVERE HAIL.
 HOWEVER...DEEP LAYER FLOW FIELDS AND SHEAR ARE VERY WEAK WITHIN THE
CENTER OF LOWER/MID TROPOSPHERIC RIDGING.  A SLOW PROPAGATION OFF
THE HIGHER TERRAIN INTO THE PIEDMONT OF SOUTH CAROLINA AND NORTHERN
GEORGIA APPEARS POSSIBLE LATE THIS AFTERNOON.  HOWEVER...IT
CURRENTLY APPEARS THAT POTENTIAL IS LOW FOR COLD POOL CONSOLIDATION
AND UPSCALE GROWTH INTO A STORM CLUSTER CAPABLE OF PRODUCING A
BROADER SCALE DAMAGING WIND THREAT.
