AREAS AFFECTED...NRN SC AND CNTRL NC

CONCERNING...SEVERE THUNDERSTORM WATCH 147...

VALID 032059Z - 032230Z

SEVERAL SUPERCELLS ARE ONGOING ACROSS THE ERN PART OF WW 147. LARGE
HAIL AND WIND DAMAGE WILL BE LIKELY WITH THE STORMS OVER THE NEXT
FEW HOURS. TORNADOES WILL ALSO BE POSSIBLE WITH THE STRONGER
SUPERCELLS AS THE STORMS TRACK EWD INTO NERN SC AND SCNTRL NC BY
EARLY EVENING.

WATER VAPOR IMAGERY AND RUC ANALYSIS CURRENTLY SHOW A STRONG
VORTICITY MAX IN NRN VA WITH A BAND OF WELL-FOCUSED LARGE-SCALE
ASCENT MOVING ACROSS THE WRN CAROLINAS ATTM. THE SUPERCELLS ARE
ONGOING ALONG THE LEADING EDGE OF ASCENT JUST AHEAD OF A 70 KT
MID-LEVEL JET. THE LIFT COMBINED WITH STEEPENING LAPSE RATES AND THE
RELATIVELY DRY BOUNDARY LAYER (SFC DEWPOINTS IN THE 40S F) WILL
FAVOR WIND DAMAGE AND LARGE HAIL. THE WIND DAMAGE POTENTIAL WILL BE
ENHANCED WEST OF I-77 WHERE SFC TEMP-DEWPOINT DEPRESSIONS EXCEED 30
DEGREES F. AS THE SUPERCELLS MOVE EWD INTO NERN SC AND SCNTRL
NC...THE TORNADO POTENTIAL WILL INCREASE SOME DUE TO GREATER
LOW-LEVEL MOISTURE WHERE SFC DEWPOINTS ARE CURRENTLY IN THE LOWER TO
MID 50S F.
