DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0230 AM CDT THU SEP 27 2012

VALID 291200Z - 301200Z

...SYNOPSIS...
AN UPPER LOW IS FORECAST TO CONTINUE RETROGRADING SSWWD ACROSS THE
GREAT LAKES REGION THIS PERIOD...WITH A RESULTING EXPANSION IN ERN
U.S. TROUGHING TO RESULT.

AT THE SURFACE...A FRONT CONTINUING TO DRIFT SWD/SEWD -- EXTENDING
FROM THE COASTAL CAROLINAS WSWWD ACROSS THE GULF COAST STATES INTO
TX DURING THE AFTERNOON -- WILL AGAIN BE A FOCUS FOR WIDESPREAD
SHOWERS AND THUNDERSTORMS.

ATTM...ANTICIPATED CAPE/SHEAR ENVIRONMENT INVOF THE FRONT APPEARS
GENERALLY UNSUPPORTIVE OF APPRECIABLE SEVERE THREAT. A VERY
ISOLATED THREAT FOR HAIL/WIND MAY EXIST ACROSS ERN NC DURING THE
AFTERNOON DEPENDING UPON WHETHER THE FRONT REMAINS ONSHORE HERE OR
DRIFTS FARTHER SE. ALSO...WITH WEAK SURFACE LOW EVOLUTION -- NOT
WELL HANDLED BETWEEN THE MODELS -- FORECAST INVOF COASTAL TX...THIS
COULD ENHANCE LOW-LEVEL SHEAR/ROTATION POTENTIAL. STILL...THREATS
IN BOTH OF THESE AREAS REMAINS LOW/UNCERTAIN...SUCH THAT NO
PROBABILITY AREAS WILL BE INCLUDED THIS FORECAST.
