AREAS AFFECTED...SRN VA...NERN TN...WRN AND CNTRL NC AND ERN SC

CONCERNING...SEVERE POTENTIAL...WATCH LIKELY

VALID 101818Z - 101945Z

SCATTERED THUNDERSTORMS ARE EXPECTED TO DEVELOP SEWD THROUGH THE SRN
APPALACHIANS AND INTO THE CAROLINAS. LARGE HAIL AND DAMAGING WIND
SHOULD BE THE PRIMARY THREATS. AN ADDITIONAL WW WILL LIKELY
BE NEEDED WITHIN THE NEXT 1-2 HOURS.

A WARM FRONT EXTENDS FROM SERN NC NWWD THROUGH WRN NC...WRN VA INTO
THE OH VALLEY. THE WARM SECTOR CONTINUES TO DESTABILIZE WITH MLCAPE
FROM 2000-2500 J/KG FROM ERN TN...WRN VA INTO THE CAROLINAS. STORMS
HAVE ALREADY DEVELOPED OVER THE OH VALLEY ALONG ERN FRINGE OF THE
STRONGER EML/CAP FROM IND SEWD THROUGH ERN KY. THIS ACTIVITY WILL
LIKELY INTENSIFY AS IT ADVANCES SEWD AND BECOMES ROOTED IN THE
DESTABILIZING BOUNDARY LAYER. RUC PFCS INDICATE VERY LITTLE
REMAINING CONVECTIVE INHIBITION ONCE SURFACE TEMPERATURES RISE INTO
THE LOW-MID 80S. ADDITIONAL STORMS WILL LIKELY DEVELOP OVER THE SRN
APPALACHIANS AS WELL AS ALONG SEA-BREEZE BOUNDARIES. WEAK SWLY LOW
LEVEL FLOW VEERING TO NWLY 50 KT AT 500 MB WILL SUPPORT
SUPERCELLS...BUT SOME STORMS MAY EVENTUALLY CONSOLIDATE INTO
CLUSTERS/BOWS AS THEY DEVELOP SEWD.
