LATEST RUC GUIDANCE SUGGESTS THAT SOUTHERLY 850 FLOW TO THE LEE OF
THE SOUTHERN APPALACHIANS IS BEGINNING TO WEAKEN. BUT...LOW-LEVEL
HODOGRAPHS REMAIN MAXIMIZED AND SUPPORTIVE OF THE RISK OF TORNADOES

BAROCLINIC ZONE ACROSS THE WESTERN NORTH CAROLINA PIEDMONT. AND...
THUNDERSTORM ACTIVITY REMAINS LOCALLY ENHANCED NEAR A SIGNIFICANT 2
HOUR SURFACE PRESSURE FALL CENTER...WHICH APPEARS COINCIDENT WITH
STRONGEST BOUNDARY LAYER WARMING/MOISTENING...NOW NORTHEAST OF
CHARLOTTE. POTENTIAL FOR ISOLATED/BRIEF TORNADOES APPEARS HIGHEST
WITH THIS PERTURBATION...WHICH MAY PROGRESS ACROSS THE
WINSTON-SALEM/GREENSBORO AREA BY 12-13Z.
