DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0227 AM CDT TUE OCT 21 2008

VALID 231200Z - 241200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
THE LARGE UPPER LOW OVER THE CENTRAL CONUS WILL REMAIN THE PRIMARY
FEATURE ALOFT DAY 3...WITH THE FEATURE EXPECTED TO DRIFT SLOWLY EWD
THROUGH THE PERIOD. AT THE SURFACE...THE LOW IS FORECAST TO FILL AS
THE SYSTEM REMAINS VERTICALLY-STACKED...AND THE ASSOCIATED SURFACE
FRONT SHOULD WEAKEN AS IT TRANSLATES EWD ACROSS THE S CENTRAL CONUS
INTO THE SOUTHEAST. ELSEWHERE...GENERALLY QUIESCENT WEATHER IS
FORECAST FROM A CONVECTIVE PERSPECTIVE.

...CENTRAL GULF COAST REGION...
MOIST LOW LEVELS BUT WEAK INSTABILITY SHOULD CHARACTERIZE THE WARM
SECTOR SHIFTING SLOWLY EWD ACROSS THE CENTRAL GULF COAST REGION THIS
PERIOD. WHILE SHOWERS AND SCATTERED THUNDERSTORMS WILL LIKELY
PERSIST ACROSS PORTIONS OF THE SERN QUARTER OF THE CONUS...A MAIN
LIMITING FACTOR WILL BE THE OVERALL LACK OF INSTABILITY.

WITH FAIRLY STRONG DEEP-LAYER FLOW SPREADING SLOWLY EWD SUGGESTING
SHEAR FAVORABLE FOR STORM ORGANIZATION...WILL INTRODUCE A
SMALL/LOW-PROBABILITY THREAT AREA CENTERED OVER THE CENTRAL GULF
COAST REGION. HOWEVER...THERMODYNAMIC LIMITATIONS ARE EXPECTED TO
HINDER THE OVERALL THREAT.
