DAY 1 CONVECTIVE OUTLOOK RESENT 2
NWS STORM PREDICTION CENTER NORMAN OK
0951 AM CDT WED OCT 08 2008
VALID 081300Z - 091200Z
...NO SVR TSTM AREAS FORECAST...
...NERN GULF COAST/SOUTHEAST...
PROGRESSIVE MID/UPPER LEVEL LOW NOW MOVING EWD ACROSS THE LOWER MS
RIVER VALLEY WILL CONTINUE ESEWD INTO THE NERN GULF COAST REGION
THROUGH TONIGHT. AHEAD OF THIS FEATURE...RICH GULF MOISTURE DEFINED
BY LOWER 70F SURFACE DEW POINTS WILL PERSIST INTO THE FL PANHANDLE
AND FAR SERN AL/SRN GA. IN CONTRAST...ENTRENCHED SURFACE HIGH
PRESSURE OFF THE EAST COAST WILL SUSTAIN ENELY WINDS AND RELATIVELY
COOL/STABLE AIR INTO THE SRN APPALACHIANS/MOST OF THE CAROLINAS.
HOWEVER AHEAD OF APPROACHING SYSTEM...EFFECTIVE WARM FRONT WILL TEND
TO LIFT SLOWLY NWD INTO CENTRAL GA/SC THIS AFTERNOON. NWD MOVEMENT
OF THE SURFACE WARM FRONT WILL BE HINDERED BY EXTENSIVE CLOUDS/MOIST
CONVECTION EXPECTED TO PERSIST WITHIN ZONE OF DEEP ASCENT SPREADING
ACROSS THE SRN APPALACHIANS THROUGH MUCH OF ERN AL/GA/UPSTATE SC.
DESPITE THE RICH BOUNDARY LAYER MOISTURE EXPECTED AHEAD OF
APPROACHING UPPER LOW AND ASSOCIATED SURFACE COLD FRONT...RELATIVELY
WEAK LAPSE RATES AND WEAKENING LOW LEVEL SHEAR SHOULD ACT TO LIMIT
SEVERITY OF THUNDERSTORMS THAT ARE EXPECTED TO INCREASE ACROSS THIS
REGION THROUGH THE PERIOD. GREATEST POTENTIAL FOR LOW-TOPPED
SUPERCELLS SHOULD PERSIST NEAR THE GULF COAST WHERE MODEST
INSTABILITY WILL PERSIST. OTHERWISE...A FEW STRONGER/MORE ORGANIZED
STORM CLUSTERS SHOULD INCREASE NEAR THE SURFACE COLD FRONT ALONG WRN
PERIPHERY OF EARLY DAY STORMS IF SUFFICIENT HEATING OCCURS.
ISOLATED STRONG/ISOLATED DAMAGING WINDS MAY ACCOMPANY THIS
ACTIVITY...ALTHOUGH ANY MARGINAL SEVERE THREAT IS EXPECTED TO
DIMINISH AFTER DARK.
