SPC AC 240604

DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1204 AM CST SAT NOV 24 2012

VALID 251200Z - 261200Z

...NO TSTM AREAS FORECAST...

...SYNOPSIS...
THE LARGE SCALE PATTERN WILL BEGIN TO REAMPLIFY OVER THE CONUS ON
SUNDAY...HIGHLIGHTED BY GRADUAL LONGWAVE TROUGH DEVELOPMENT
OVER THE CANADIAN/NORTHERN CONUS ROCKIES AND PLAINS. RELATIVELY
STABLE/DRY CONDITIONS WILL CONSIDERABLY LIMIT TSTM POTENTIAL ACROSS
THE CONUS.

FOR EAST TX/ARKLATEX...THE ONSET OF A WARM ADVECTION/ELEVATED
MOISTURE RETURN REGIME COULD ACCOUNT FOR A LOW PROBABILITY TSTM
POTENTIAL SUNDAY NIGHT/EARLY MONDAY ACROSS THE ARKLATEX REGION...AS
A COLD FRONT OTHERWISE SPREADS SOUTHEASTWARD TOWARD THE REGION.
HOWEVER...GIVEN THE LIKELIHOOD OF WEAK FORCING FOR ASCENT/LINGERING
CAPPING ALOFT...TSTM PROBABILITIES CURRENTLY APPEAR TO BE BELOW 10
PERCENT PRIOR TO 12Z MONDAY.

..GUYER.. 11/24/2012
