DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1123 AM CDT SAT OCT 31 2009

VALID 311630Z - 011200Z

...NO TSTM AREAS FORECAST...

...SOUTHEAST...
DE-AMPLIFYING SHORTWAVE TROUGH NOW MOVING ACROSS THE LOWER MS RIVER
VALLEY SHOULD MAINTAIN AREA OF SHALLOW MOIST CONVECTION INVOF WEAK
SURFACE COLD FRONT MOVING ACROSS THE SOUTHEASTERN U.S. THROUGH THE
PERIOD. HOWEVER...PRE-FRONTAL LAPSE RATES REMAIN QUITE WEAK UNDER
WARM MID LEVEL TEMPERATURES. THIS WILL LIMIT SBCAPE AND POTENTIAL
FOR CHARGE SEPARATION WITHIN MOIST CONVECTION. ALTHOUGH A SPORADIC
LIGHTNING STRIKE OR TWO MAY ACCOMPANY THE MORE INTENSE
CONVECTION...OVERALL THUNDERSTORM POTENTIAL REMAINS QUITE LOW.
