DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1130 AM CST FRI DEC 14 2012

VALID 151200Z - 161200Z

...NO SVR TSTM AREAS FORECAST...

...SOUTHEAST TX/ARKLATEX/MID-SOUTH...
NEUTRAL HEIGHT TENDENCIES/WEAK FORCING ALOFT WILL BE PREVALENT OVER
THE REGION MUCH OF THE DAY IN THE WAKE OF A DEAMPLIFYING SHORTWAVE
TROUGH MOVING TOWARD THE MIDWEST/GREAT LAKES REGION...AND AHEAD OF A
SECONDARY LOW AMPLITUDE TROUGH EMERGING FROM THE SOUTHERN ROCKIES.
AN EAST-SOUTHEASTWARD MOVING COLD FRONT WILL GRADUALLY
DECELERATE/STALL ACROSS THE REGION IN A NORTHEAST-SOUTHWEST
ORIENTATION ACROSS THE REGION.

WHILE STEADY LOW-LEVEL MOISTENING WILL OCCUR AHEAD OF THE
FRONT...CLOUD COVER/WEAK LAPSE RATES SHOULD HINDER THE DEGREE OF
DESTABILIZATION. EVEN SO...SUFFICIENT LOW-LEVEL CONFLUENCE AND
LOCALLY STRONGER HEATING/WEAKENING INHIBITION ACROSS PARTS OF THE
REGION MAY INFLUENCE THE MATURATION AND INTENSIFICATION OF TSTMS
SATURDAY AFTERNOON WITHIN A CORRIDOR INCLUDING EAST
TX...LA...SOUTHERN/EASTERN AR INTO NORTHERN MS.

GIVEN THE DEGREE OF VERTICAL SHEAR...THE POTENTIAL FOR SOME SMALL
LINE SEGMENTS/EMBEDDED SUPERCELL STRUCTURES WILL EXIST.
FURTHERMORE...WHILE DIURNALLY HEATING WILL ABATE...THE GLANCING
INFLUENCE OF A SECONDARY SOUTHERN STREAM SHORTWAVE TROUGH/JET STREAM
MAY HELP SUSTAIN OR REINVIGORATE CONVECTION WITHIN THE WARM SECTOR
SATURDAY NIGHT. WHILE A PARTICULARLY ORGANIZED/SUSTAINED SEVERE RISK
IS NOT CURRENTLY ANTICIPATED...POTENTIAL DAMAGING WIND/TORNADO
HAZARDS CANNOT BE DISCOUNTED SATURDAY AFTERNOON/EARLY EVENING.
