INTERESTING EVENT WITH QUITE A DEEP STABLE POOL OVER THE CWA WITHIN
AN IN SITU DAMMING AIR MASS. COASTAL FRONT REMAINS WELL DEFINED ON
MSAS... HOWEVER FAIRLY RAPID FRONTOGENESIS HAS TAKEN PLACE OVER THE
PIEDMONT IN THE LAST FEW HOURS WITH GOOD MSLP FALLS OVER THE COASTAL
PLAIN. OBSERVED WINDS FROM GSO-CLT WESTWARD HAVE TURNED N OR NW
WHEREAS WINDS ON THE EAST SIDE OF THE DEVELOPING BOUNDARY ARE
UNIFORM SE. THIS SUPPORTS THE LATEST RUC WHICH INDICATES LOW LEVEL
THICKNESSES RISING 20 M OVER THE NEXT 3-4 HOURS. MIXING DOWN THE
WARMER AIR ON THE AREA SOUNDINGS GIVES A TEMP RISE TO THE LOWER TO
MID 60S... BUT WITH COMPLETE DESTABILIZATION NOT EXPECTED OVER THE
WESTERN PIEDMONT... WILL HAVE TEMPS RISING SLOWLY INTO THE 55-60
DEGREE RANGE THERE WITH MID 60S IN THE EAST (AND THIS MAY BE
CONSERVATIVE). WILL RETAIN MENTION OF OCCASIONAL RAIN... ALTHOUGH
MOST OF IT TONIGHT IS LIKELY TO BE RATHER LIGHT AND DRIZZLY. WILL
KEEP ISOLATED THUNDER WHERE IT IS MENTIONED... AND WILL ADD AREAS OF
FOG EVERYWHERE.

ENVIRONMENT REMAINS HIGHLY SHEARED WITH TREMENDOUS SR HELICITIES
OVER 1300 M2/S2 ON THE GSO SOUNDING AND VWPS SHOWING 50+ KT AT 3-5
KFT. EVEN ELEVATED CAPE IS SMALL... THUS THE FOCUS FOR POTENTIAL
SEVERE ACTIVITY WILL BE LARGELY EAST OF THE RAH CWA... BUT ANY
MIXING-DOWN OF THESE WINDS COULD DO SOME DAMAGE AND CERTAINLY BEARS
WATCHING.

TOMORROW SHOULD SEE MORNING CLOUDINESS FOLLOWED BY INCREASING SUN AS
DOWNSLOPING KICKS IN... BUT DO EXPECT A REDEVELOPMENT OF STRATOCU
PARTICULARLY OVER THE EASTERN/SOUTHERN CWA.
