...THERE IS A SLGT RISK OF SVR TSTMS ACROSS ERN SC AND A PORTION OF
ERN GA...

...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF ERN NM INTO THE
TX PANHANDLE...

AMENDED FOR AN UPGRADE TO SLIGHT RISK OVER PARTS OF ERN NM AND TX
PANHANDLE

...PARTS OF ERN NM INTO THE TX PANHANDLE...
SHORT WAVE TROUGH...CURRENTLY OVER NM...WILL CONTINUE TO WEAKEN AS
IT TRACKS EWD ACROSS THE SRN HIGH PLAINS.  LOW-LEVEL CLOUDS/COOL AIR
MASS HAVE REMAINED IN PLACE ACROSS MUCH OF WRN TX INTO SERN NM...
LIMITING DESTABILIZATION IN THESE AREAS.  HOWEVER...AIR MASS FARTHER
WEST HAS BECOME MODERATELY UNSTABLE FROM FAR SWRN TX NWD INTO
SRN/CENTRAL NM WITH MLCAPE RANGING FROM 1000-1500 J/KG.  MID-50S
SURFACE DEWPOINTS HAVE ALSO RETURNED NEWD ACROSS NERN NM AND THE
TX/OK PANHANDLES ALONG A LEE TROUGH...WHERE SURFACE HEATING AND
STEEP LAPSE RATES ARE ALSO RESULTING IN A NARROW AXIS OF MODERATE
INSTABILITY /MLCAPE UP TO 1000 J/KG/.

FORCING WITH THE SRN STREAM SHORT WAVE TROUGH WILL BE GREATEST OVER
NERN NM INTO THE OK/TX PANHANDLES THROUGH THE LATE AFTERNOON/EARLY
EVENING WHERE STRONG TO SEVERE STORMS HAVE ALREADY DEVELOPED. 
MODERATE INSTABILITY AND 50 KT OF WLY MID LEVEL FLOW RESULTING IN
40-55 KT OF DEEP LAYER SHEAR WILL SUPPORT A FEW SEVERE STORMS WITH
LARGE HAIL AND DAMAGING WINDS THE PRIMARY THREATS.

FARTHER SOUTH...ONGOING ELEVATED STORMS ARE EXPECTED TO PERSIST OVER
WRN TX WITH ACTIVITY CONTINUING TONIGHT...POTENTIALLY SPREADING NWD
TO ALONG THE RED RIVER VALLEY...AS A WAA REGIME INCREASES ALONG A
STRENGTHENING LLJ.

...20Z DISCUSSION FOR SRN MID ATLANTIC STATES...
REGIONAL RADARS/LIGHTNING DATA SHOWED THUNDERSTORMS DEVELOPED ALONG
A LEE TROUGH FROM CENTRAL GA TO SOUTH CENTRAL NC...AS FORCING WITH A
SHORT WAVE TROUGH MOVING EWD ACROSS SC IS ENHANCING DEEP LAYER
ASCENT.  MODERATELY UNSTABLE AIR MASS IN ADVANCE OF THIS ACTIVITY
COMBINED WITH 30-40 KT WLY MID-LEVEL WINDS RESULTING IN SUFFICIENT
DEEP LAYER SHEAR WILL CONTINUE TO SUPPORT POTENTIAL FOR ORGANIZED
STORMS AS THE SHORT WAVE TRACKS EAST.  GIVEN THE INCREASE IN
THUNDERSTORM ACTIVITY THE LAST FEW HOURS...AND CONTINUED THREAT FOR
A FEW SEVERE STORMS A SLIGHT RISK HAS BEEN ADDED FROM ERN SC INTO
PARTS OF ERN GA.  WEAK LAPSE RATES SHOULD LIMIT THE HAIL
POTENTIAL...BUT DEEP WLY FLOW WILL FAVOR MORE OF A WIND THREAT.
