DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1124 AM CDT MON SEP 27 2010
VALID 271630Z - 281200Z
...THERE IS A SLGT RISK OF SVR TSTMS OVER PORTIONS OF GA/SC INTO THE
DELMARVA REGION...
A LARGE UPPER LOW OVER THE GULF COAST STATES WILL ROTATE EASTWARD
ACROSS THE SOUTHEAST US LATER TODAY AND TONIGHT. THIS WILL CONTINUE
TO RESULT IN WIDESPREAD SHOWERS AND THUNDERSTORMS OVER A LARGE AREA
OF THE SOUTHEAST...INCLUDING A RISK OF LOCALLY SEVERE STORMS.
...SC/NC COAST SHORT-TERM...
MORNING RADAR/SATELLITE IMAGERY SHOW A COMPLEX SETUP ACROSS GA/SC/NC
WITH SEVERAL CLUSTERS OF THUNDERSTORMS. THE EFFECTIVE OUTFLOW
BOUNDARY HAS MOVED TO NEAR THE COAST...SUGGESTING THAT THE GREATEST
SHORT-TERM RISK OF SEVERE IS LIKELY CONFINED TO THE IMMEDIATE
COASTAL AREAS OF SC...AND FAR EASTERN NC. SMALL BOWING SEGMENTS
ALONG THE LEADING EDGE OF THIS CONVECTION MAY POSE A RISK OF LOCALLY
DAMAGING WINDS OR AN ISOLATED TORNADO.
...CENTRAL NC INTO DELMARVA...
LATER THIS AFTERNOON...SOME MODEL SOLUTIONS AND SATELLITE TRENDS
INDICATE A POTENTIAL FOR DESTABILIZATION OVER CENTRAL NC NEAR THE
REMNANT FRONT. STRONG VERTICAL SHEAR WILL BE IN PLACE OVER THIS
REGION AS THE UPPER WAVE APPROACHES FROM THE SOUTHWEST. A POCKET OF
COOLER TEMPERATURES ALOFT AND STEEPENING LAPSE RATES MAY PROVIDE
SUFFICIENT THERMODYNAMIC SUPPORT FOR THE DEVELOPMENT OF ISOLATED
STORMS CAPABLE OF DAMAGING WINDS OR A TORNADO. THESE STORMS WILL
TRACK NORTHEASTWARD AFTER DARK INTO PARTS OF VA AND EVENTUALLY
NJ/DE/MD WITH A CONTINUED SEVERE RISK.
...NORTHERN GA...
FINALLY...THE POCKET OF STEEPER LAPSE RATES CURRENTLY OVER
AL/GA...COUPLED WITH DECREASING CLOUDS OVER GA...MAY RESULT IN
SCATTERED LOW-TOPPED THUNDERSTORMS THIS AFTERNOON. THIS AREA MAY
SEE A FEW STRONG STORMS WITH DAMAGING WINDS POSSIBLE.
