VECTOR STEERING FLOW HAS THIS MCV DRIVEN CONVECTION MAKING A RIGHT
TURN OVER THE RIDGE AND IMPACTING THE NRN TIER OF THE FORECAST AREA
FROM MID AFTERNOON THROUGH EARLY EVENING. A DEEP...ELEVATED MIXED
LAYER ON THE OHX SOUNDINGS THIS MORNING SUGGESTS THAT VERY STEEP
LAPSE RATES WILL TRAVERSE THE SRN APPALACHIANS TO ALLOW THE SYSTEM
TO BE MAINTAINED. SFC BASED CAPE VALUES ACROSS THE FORECAST AREA
SHOULD BE QUITE ROBUST EVERYWHERE EXCEPT THE NW NC PIEDMONT...WHERE
LOW CLOUDS NE OF THE STALLED SFC FRONT WILL LINGER AND KEEP TEMPS A
BIT COOLER THAN PREVIOUSLY FORECAST. FORCING WILL BE BEST IN THE
LOWER CAPE AIR ACROSS THE NORTH...WHILE 1000 TO 2000 J/KG CAPE LOOK

FLOW SHOWERS IN THE NC MOUNTAINS ALONG THE TN BORDER. SMALL CAPE AND
MODERATE HELICITY WILL ACCOMPANY THE FRONT...AND SEVERE WEATHER
APPEARS POSSIBLE AROUND FRONTAL PASSAGE. QPF WILL BE LIMITED BY THE
SPEED OF THE SYSTEM AND WEAK INFLOW AHEAD OF IT.
