This line means business, eveyone be safe out there!

LINE SHOULD MOVE INTO NW CORNER OF CWA

AROUND 10AM... I-85 BY 3PM AND AHN-MCN-AMERICUS LINE BY 7PM AND

EXITING SE CORNER OF CWA AROUND 10PM. INGREDIENTS STILL APPEAR

SUFFICIENT FOR AT LEAST ISOLD AREAS OF WIND DMG OR BRIEF TORNADOES.

AS OFTEN THE CASE...06Z NAM MLCAPE SHOWING MORE INSTABILITY THAN

OTHER MODELS WITH VALUES AROUND 400-700 J/KG. 00Z GFS HAS 200-400

J/KG OVER ALL BUT NE GA. VERTICAL WIND SHEAR WILL BE VERY STRONG.

0-1KM BULK SHEAR 40-50KTS SEEN ON GFS AND NAM. FAVORABLE CIN...LCL

AND DEEP LAYER SHEAR YIELDING DECENT SIG TOR PARAMETER

SPC AC 300609

DAY 1 CONVECTIVE OUTLOOK RESENT 1

NWS STORM PREDICTION CENTER NORMAN OK

1209 AM CST WED JAN 30 2013

VALID 301200Z - 311200Z

...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF THE CNTRL GULF

COAST STATES...ERN GULF COAST STATES...CAROLINAS...SRN APPALACHIAN

MTNS...CNTRL APPALACHIAN MTNS AND MID-ATLANTIC...

...GULF COAST STATES/SRN APPALACHIAN MTNS/CAROLINAS...

AN UPPER-LEVEL TROUGH WILL APPROACH THE MS VALLEY TODAY AS AN

INTENSE 100 TO 125 KT MID-LEVEL JET TRANSLATES EWD ACROSS THE OH AND

TN VALLEYS. ON THE ERN EDGE OF THE MID-LEVEL JET...A NEARLY

CONTINUOUS SQUALL-LINE WILL LIKELY BE ONGOING AT DAYBREAK. THE

SQUALL-LINE IS EXPECTED TO MOVE EWD ACROSS THE SRN APPALACHIAN MTNS

AND ECNTRL GULF COAST STATES THIS MORNING AND INTO THE CAROLINAS

THIS AFTERNOON. A GRADUAL INTENSIFICATION OF THE LINE MAY OCCUR THIS

MORNING AS SFC TEMPS WARM AND DESTABILIZATION OCCURS AHEAD OF THE

LINE. MODEL FORECASTS SUGGEST THE LINE WILL BE MAINTAINED EWD ACROSS

GA AND THE WRN CAROLINAS THIS AFTERNOON WITH THE LINE MOVING ACROSS

THE ATLANTIC COASTAL PLAINS THIS EVENING.

FORECAST SOUNDINGS JUST AHEAD OF THE LINE AT MIDDAY FROM ATLANTA

SWWD ACROSS SERN AL SHOW SBCAPE VALUES INCREASING TO AROUND 1000

J/KG. THIS COMBINED WITH 60 TO 70 KT OF DEEP LAYER SHEAR AND STRONG

LARGE-SCALE ASCENT SHOULD BE FAVORABLE FOR SEVERE STORM DEVELOPMENT

WITHIN THE SQUALL-LINE. THE LINE SHOULD BE AN EFFICIENT WIND DAMAGE

PRODUCER DUE TO 60 KT OF FLOW JUST ABOVE THE SFC. ISOLATED WIND

GUSTS OVER 70 KT COULD OCCUR DURING THE AFTERNOON WHERE THE

SQUALL-LINE INTERACTS WITH MODERATE INSTABILITY. A FEW TORNADOES MAY

ALSO OCCUR ACROSS THE SRN APPALACHIAN MTNS SWWD INTO THE ECNTRL GULF

COAST STATES ALONG THE WRN EDGE OF AN IMPRESSIVE 60 TO 70 KT

LOW-LEVEL JET.

...CNTRL APPALACHIAN MTNS/MID-ATLANTIC...

AN UPPER-LEVEL TROUGH WILL MOVE INTO THE MID TO UPPER MS VALLEY

TODAY AS A POWERFUL 100 TO 125 KT MID-LEVEL JET MOVES EWD INTO THE

OH AND TN VALLEYS. A SQUALL-LINE SHOULD BE ONGOING ALONG THE ERN

EDGE OF THE MID-LEVEL JET FROM THE UPPER OH VALLEY EXTENDING SSWWD

INTO CNTRL KY AND MIDDLE TN. THIS SQUALL-LINE IS FORECAST TO MOVE

EWD ACROSS THE CNTRL APPALACHIAN MTNS THIS MORNING AND INTO THE

VIRGINIA'S BY THIS AFTERNOON. ALTHOUGH INSTABILITY IS FORECAST TO

REMAIN WEAK ACROSS THE CNTRL APPALACHIAN MTNS AND VIRGINIA'S...DEEP

LAYER SHEAR AND LARGE-SCALE ASCENT IS FORECAST TO BE VERY STRONG.

THIS SHOULD ENABLE THE SQUALL-LINE TO BE MAINTAINED THIS AFTERNOON

WITH SOME INTENSIFICATION AS SFC TEMPS WARM AHEAD OF THE LINE.

ALTHOUGH AN ISOLATED TORNADO THREAT CAN NOT BE RULED OUT WITH BOWING

LINE-SEGMENTS DUE TO THE STRONG LOW-LEVEL SHEAR...THE GREATER THREAT

SHOULD BE DAMAGING WIND GUSTS ASSOCIATED WITH THE SQUALL-LINE. THE

SEVERE THREAT IS EXPECTED TO BE MORE ISOLATED NWD ACROSS THE

MID-ATLANTIC WHERE INSTABILITY SHOULD BE VERY WEAK.
