   AREAS AFFECTED...SERN WV...WRN VA...WRN NC...FAR NWRN SC
   
   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 
   
   VALID 021831Z - 021930Z
   
   STRONG TO MARGINALLY SEVERE STORMS WILL DEVELOP OVER THE NEXT 1-2
   HOURS. STRONG...GUSTY WINDS WILL BE THE MAIN THREAT BUT SOME
   MARGINALLY SEVERE HAIL IS ALSO POSSIBLE. THE STORMS ARE EXPECTED TO
   INITIALLY BE TIED TO HIGHER TERRAIN BUT WILL SLOWLY MIGRATE S/SEWD
   WITH TIME INTO ADJACENT FOOTHILLS.
   
   A FEW WEAK THUNDERSTORMS HAD BEGUN TO DEVELOP ALONG THE HIGHER
   TERRAIN OF THE APPALACHIANS FROM SWRN NC NEAR AVL NWD TOWARDS ROA IN
   WRN VA. WHILE THIS REGION WAS CHARACTERIZED BY RELATIVELY WEAK FLOW
   /20-30 KT BULK SHEAR AT BEST/ SBCAPE VALUES WERE APPROACHING
   2500-3500 J/KG. THIS WILL AID IN VIGOROUS STORM DEVELOPMENT AND WITH
   TEMPERATURE-DEWPOINT SPREADS AROUND 25 DEGREES AND LOW LEVEL LAPSE
   RATES NEAR 8.5 C/KM...STRONG DOWNBURST WINDS WILL BE POSSIBLE.
   
   12Z RAOBS FROM GSO AND RNK SUGGEST MID LEVEL LAPSE RATES ONLY
   MARGINALLY SUPPORTIVE OF LARGE HAIL AND SOME FORECAST SOUNDINGS
   SUGGEST SOME WARMING ALOFT...FURTHER HINDERING LARGE HAIL
   PRODUCTION.  HOWEVER...VERY UNSTABLE AIR MASS AND POTENTIALLY VERY
   STRONG UPDRAFTS...STRONGEST CELLS COULD PRODUCE MARGINALLY SEVERE
   HAIL.
   
   WEAK DEEP LAYER FLOW WILL LEAD TO SLOW STORM MOTION WITH MEAN WIND
   VECTORS FROM THE N/NW. EXPECT STORMS TO SLOWLY MIGRATE FROM HIGHER
   TERRAIN TOWARD LOWER FOOTHILLS THIS AFTERNOON/EVENING AT AROUND
   15-20 MPH.
