AREAS AFFECTED...SC...NC

CONCERNING...SEVERE THUNDERSTORM WATCH 467...

VALID 122034Z - 122200Z

WATER VAPOR IMAGERY AND REGIONAL RADAR IMAGERY CURRENTLY SHOW A
LARGE MCS ONGOING ACROSS NRN SC AND SRN NC. THE STRONGER CELLS
WITHIN THE MCS WILL HAVE A POTENTIAL FOR LARGE HAIL AND WIND DAMAGE
OVER THE NEXT FEW HOURS.

LATEST SFC ANALYSIS SHOWS A NEARLY STATIONARY FRONTAL BOUNDARY
EXTENDING WEST TO EAST FROM NEAR GREENVILLE SC TO NEAR JACKSONVILLE
NC. SOUTH OF THE BOUNDARY...SFC DEWPOINTS ARE IN THE 70S F AND
MLCAPE VALUES RANGE FROM 1500-2500 J/KG. THIS COMBINED WITH
LARGE-SCALE ASCENT ASSOCIATED WITH AN EAST COAST UPPER-LEVEL TROUGH
WILL SUSTAIN THE ACTIVITY THROUGH THE REMAINDER OF THE AFTERNOON.
REGIONAL WSR-88D VWPS SHOW MODERATE VERTICAL SHEAR PROFILES WITH
VEERING LOW-LEVEL WINDS COMBINED WITH THE INSTABILITY SUGGESTS
SUPERCELLS WITH LARGE HAIL AND WIND DAMAGE WILL CONTINUE TO BE
POSSIBLE. IN ADDITION...STRONG TO SEVERE MULTICELL STORMS WILL
CONTINUE TO BE LIKELY. STEEP LOW-LEVEL LAPSE RATES AND STRONG
OUTFLOW BOUNDARY INTERACTIONS WILL BE FAVORABLE FOR WIND DAMAGE WITH
THE STRONGER CELLS.
