DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0741 AM CDT THU OCT 28 2010
VALID 281300Z - 291200Z
...NO SVR TSTM AREAS FORECAST...
...SYNOPSIS...
MODERATE TO STRONG WSW FLOW WILL PREVAIL OVER THE CAROLINAS AND MID
ATLANTIC STATES THIS PERIOD...AHEAD OF AMPLIFYING SHORTWAVE IMPULSE
CROSSING THE OH AND TN VLYS. THE IMPULSE SHOULD CONTINUE E OFF THE
NC CST BY THE END OF THE PERIOD AS LARGER SCALE CYCLONIC CIRCULATION
LINGERS OVER ONT AND THE LWR GRT LKS.
AT THE SFC...A SERIES OF WEAK FRONTAL SURGES WILL CONSOLIDATE/
STRENGTHEN EXISTING COLD FRONTAL ZONE NOW LOCATED JUST E OF THE
CNTRL/SRN APPALACHIANS. THE STRENGTHENED FRONT SHOULD ACCELERATE
E/SE OFF THE MID AND S ATLANTIC CST TONIGHT/EARLY FRI...FINALLY
SHUNTING AXIS OF SEASONABLY RICH MOISTURE /WITH PW AOA 1.75 INCHES/
OFF THE CST.
...SOUTHEAST
WEAKLY CONFLUENT PREFRONTAL MOIST SWLY FLOW LIKELY WILL SUPPORT
DEVELOPMENT OF BROKEN BANDS/SMALL CLUSTERS OF DIURNALLY-ENHANCED
STORMS OVER CNTRL/ERN PORTIONS OF THE CAROLINAS TODAY...WHERE DEEP
FLOW REMAINS SUFFICIENT TO FOSTER STORM ORGANIZATION/LONGEVITY.
FORCING FOR ASCENT AND MID LVL LAPSE RATES WILL REMAIN RATHER WEAK
OVER THE REGION. BUT JUXTAPOSITION OF HIGH PW AXIS WITH MODERATELY
STRONG DEEP UNIDIRECTIONAL FLOW MAY FOSTER SMALL BOWING SEGMENTS
WITH A FEW STRONG TO POSSIBLY SVR WIND GUSTS IN AREAS OF STRONGER
LOW LVL HEATING.
FARTHER S...LIGHT BACKGROUND WIND FIELD APPEARS FAVORABLE FOR
SUBSTANTIAL SEA BREEZE CIRCULATIONS OVER THE FL PENINSULA. THESE
COULD FOSTER A FEW CLUSTERS OF STRONG AFTN STORMS IN THE DEEPLY
MOIST ENVIRONMENT. SCTD MAINLY DIURNAL STORMS ALSO APPEAR LIKELY
ALONG LEAD COLD FRONT OVER NRN FL AND S GA.
