AREAS AFFECTED...NC...SC
CONCERNING...SEVERE POTENTIAL...WATCH LIKELY
VALID 151729Z - 151830Z
SHOWERS HAVE RECENTLY DEVELOPED ALONG PRIMARY LOW LEVEL CONFLUENCE
ZONE ACROSS CNTRL SC. LATEST VIS SATELLITE IMAGERY SUPPORTS THIS
FEATURE WELL WITH AN ELONGATED LINE OF DEEPENING CONVECTION THAT NOW
EXTENDS INTO CNTRL PORTIONS OF NC...WEST OF SOP. ALTHOUGH THE FLOW
HAS VEERED SOME ACROSS THIS REGION THINNING CLOUDS HAVE ALLOWED
BOUNDARY LAYER TO WARM AND DESTABILIZE...ESPECIALLY ACROSS COASTAL
SC. WITH TEMPERATURES NOW WELL INTO THE 70S IT SEEMS REASONABLE
THAT UPDRAFTS WILL CONTINUE TO MATURE OVER THE NEXT FEW HOURS. DEEP
LAYER SHEAR IS MORE THAN ADEQUATE FOR SUSTAINING
SUPERCELLS...HOWEVER WEAKENING LOW LEVEL SHEAR MAY LIMIT TORNADO
POTENTIAL. WATCH WILL BE ISSUED SOON TO ACCOUNT FOR THIS INCREASING
THREAT.
