DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0230 PM CDT WED OCT 24 2007

VALID 242000Z - 251200Z

..NO SVR TSTM AREAS FORECAST...

..ERN CAROLINAS/SERN VA...
BROKEN CLOUD COVER AHEAD OF N-S COLD FRONT -- NOW LYING FROM CENTRAL
NC INTO ERN SC -- AND S OF E-W FRONT -- NOW EXTENDING FROM SERN VA
WWD ALONG THE NC/VA BORDER -- HAS RESULTED IN MODEST HEATING OF THE
MOIST WARM-SECTOR BOUNDARY LAYER. HOWEVER...WEAK LAPSE RATES
CONTINUE TO LIMIT DESTABILIZATION...WITH ONLY 500 TO 1000 J/KG
MIXED-LAYER CAPE INDICATED ACROSS THIS REGION.

DEEP-LAYER WIND FIELD ALSO REMAINS GENERALLY UNSUPPORTIVE OF
WELL-ORGANIZED STORMS -- AND THUS SEVERE THREAT REMAINS LIMITED.
0-1 KM SHEAR REMAINS SUFFICIENT FOR LOW-LEVEL ROTATION...AND A FEW
STRONGER CELLS HAVE SHOWN SOME WEAK/TRANSIENT CIRCULATIONS.
OCCASIONAL BOWING STRUCTURES AND LOCAL LINEAR ORGANIZATION ALONG
SMALL-SCALE COLD POOLS SUGGEST THAT LOCALLY GUSTY WINDS OR A BRIEF
TORNADO REMAIN POSSIBLE. ANY REMAINING THREAT SHOULD DIMINISH AFTER
SUNSET COINCIDENT WITH DIURNAL AIRMASS STABILIZATION.
