AREAS AFFECTED...WESTERN NC AND SC INTO CENTRAL GA
CONCERNING...TORNADO AND SEVERE THUNDERSTORM WATCHES 63...64...
VALID 161123Z - 161300Z
THE SEVERE WEATHER THREAT FOR TORNADO AND SEVERE THUNDERSTORM
WATCHES 63, 64 CONTINUES.
SUMMARY...DAMAGING WINDS AND SOME POTENTIAL FOR EMBEDDED TORNADOES
REMAIN POSSIBLE WITH AN EASTWARD-MOVING QLCS.
DISCUSSION...A NNE/SSW-ORIENTED BROKEN LINE HAS SHOWN SOME RECENT
SIGNS OF RE-INTENSIFICATION AS IT MOVES EAST OF THE APPALACHIANS.
HERE, A CORRIDOR OF LOWER/MIDDLE 60S DEWPOINTS IS CONTRIBUTING TO
WEAKLY UNSTABLE SURFACE-BASED INFLOW FOR THIS SYSTEM. DESPITE THE
MARGINAL BUOYANCY IN PLACE, THE STRONG LOW/DEEP-LAYER FLOW/SHEAR
CONTINUES TO FAVOR DAMAGING WINDS. ADDITIONALLY, A FEW DEEPER CORES
WITH MESOVORTEX STRUCTURE HAVE RECENTLY EVOLVED ALONG THE SOUTHERN
PART OF THE LINE (WHERE BOUNDARY-LAYER MOISTURE AND BUOYANCY ARE
MAXIMIZED), WHICH COULD POSE A RISK OF A BRIEF TORNADO AND LOCALLY
ENHANCED WIND DAMAGE. THIS RISK SHOULD BE HIGHEST WHERE DEEP-LAYER
SHEAR IS ORIENTED OBLIQUE TO THE LINE (I.E., NNW/SSE-ORIENTED PARTS
OF THE LINE).
