DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0649 PM CST SUN NOV 25 2012

VALID 260100Z - 261200Z

...NO TSTM AREAS FORECAST...

...THE ARKLAMISS REGION FOR THE REST OF TONIGHT...
LOW LEVELS HAVE MOISTENED CONSIDERABLY AT LAKE CHARLES DURING THE
PAST HALF DAY PER RAOB DATA...AND MID-EVENING SFC ANALYSIS INDICATES
THAT THE LEADING EDGE OF MID-60S DEWPOINTS HAS ADVANCED NWD TO THE
COASTAL WATERS OFF THE MIDDLE/LOWER TX COAST. CONTINUED MOISTURE
RETURN ACROSS PARTS OF THE SRN PLAINS AND LOWER MS VALLEY SOUTH OF
AN ORGANIZING FRONT WILL FOSTER ELEVATED DESTABILIZATION THROUGH THE
OVERNIGHT HOURS. AMIDST THIS DESTABILIZATION...THE TERMINUS OF A
MODEST WSWLY LOW-LEVEL JET STREAM WILL OVERLAY THE ARKLAMISS REGION.
ASSOCIATED MASS CONVERGENCE MAY BE SUFFICIENT TO SUPPORT ISOLATED
SHOWERS AND PERHAPS A THUNDERSTORM OR TWO AFTER 10Z. HOWEVER...WITH
ONLY WEAK MASS RESPONSE THROUGH THE REMAINDER OF THE PERIOD WELL IN
ADVANCE OF A SHORTWAVE TROUGH CURRENTLY ENTERING THE CNTRL HIGH
PLAINS PER WATER VAPOR IMAGERY...DEEP ASCENT WILL BE WEAK. AS
SUCH...THE COVERAGE OF ANY THUNDERSTORMS IS EXPECTED TO BE
SUFFICIENTLY LIMITED SUCH THAT A GENERAL-THUNDERSTORM AREA IS NOT
WARRANTED.
