NWS STORM PREDICTION CENTER NORMAN OK
1151 PM CDT WED SEP 12 2012

VALID 131200Z - 141200Z

...NO SVR TSTM AREAS FORECAST...

AN UPPER TROUGH SITUATED FROM THE UPPER MIDWEST SWWD INTO THE SRN
ROCKIES WILL MOVE LITTLE OVER ITS SRN HALF AS THE NRN STREAM REMAINS
PROGRESSIVE AND A SHORTWAVE TROUGH MOVES EWD FROM THE NRN PLAINS TO
THE WRN GREAT LAKES. THE INFLUENCE OF THE UPPER TROUGH ALONG WITH A
COLD FRONT CONTINUING EWD ACROSS THE MID MS RIVER VALLEY AND SWD
ACROSS THE SRN PLAINS...WILL SERVE AS THE PRIMARY FOCUSING
MECHANISMS FOR SHOWER/TSTM DEVELOPMENT THURSDAY FROM THE DESERT SW
THROUGH THE SRN PLAINS...AND NEWD TO THE MID MS RIVER VALLEY. THE
ANAFRONTAL CHARACTER OF THE OK/TX PORTION OF THE FRONT WILL TEND TO
RETARD STRONGER BUOYANCY...AND COMBINED WITH A WEAK WIND
PROFILE...UPDRAFT STRENGTH/LONGEVITY WILL REMAIN LIMITED. MODELS
INDICATE THE GREATEST INSTABILITY MAY DEVELOP IN SERN OK AND THE
ARKLATEX...WHERE AN ISOLD STRONG PULSE STORM OR TWO MAY DEVELOP
DURING THE AFTERNOON...BUT POTENTIAL APPEARS TOO LOW TO INTRODUCE
LOW WIND PROBABILITIES ATTM.
