.DISCUSSION...
/ISSUED 918 PM CST SUN DEC 21 2014/
AN EXTENSION OF THE SUBTROPICAL JET CONTINUED TO MOVE IN A SW-NE
FASHION OVER THE FORECAST AREA...WITH WINDS IN THE 130-140KT RANGE
AROUND 35KFT UP. UNDER THE JET...LOWER LEVEL STRATUS HAS RETURNED AS
LOWER LEVEL WINDS BECOME MORE SE. THE EDGE OF THOSE CLOUDS HAVE
COVERED ALL OF THE FORECAST AREA EXCEPT FAR NW ALABAMA. WELL TO OUR
SOUTH...A WEAK WAVE NEAR THE GULF COAST HAD SHOWERS ASSOCIATED WITH
IT...EXTENDING FROM SOUTH OF THE MISSISSIPPI DELTA TO SW GEORGIA.

NEW OUTPUT FROM THE NAM/RAP INDICATED THAT LOWER LEVEL MOISTURE
SHOULD SLOWLY RETURN TO THE AREA DURING THE OVERNIGHT. HOWEVER...
AMOUNTS OF IT SHOULD REMAIN ON THE SLIM SIDE...WHICH WILL KEEP RAIN
CHANCES TEMPERED. AS SUCH...HAVE REMOVED IT FROM THE FORECAST FOR THE
REST OF EVENING AREAWIDE. BUT HAVE LEFT IT IN (AS A SLIGHT CHANCE OF
RAIN/DRIZZLE) FOR OUR EASTERN AREAS. ISENTROPIC UPGLIDE AND TERRAIN
WILL BRING BETTER ODDS FOR RAIN AFFECTING THOSE AREAS. BETTER RAIN
CHANCES ARE EXPECTED LATER TOMORROW...AND ESPECIALLY ON TUE...AS A
STRONGER SYSTEM MOVES IN FROM THE SW. OTHER MAIN PARAMETERS...AKA
TEMPS/DEWPOINTS/WINDS/SKY COVER WERE LEFT AS IS. A SOLSTICE STARTING
THE WINTER SEASON EARLIER OCCURRED AT 503 PM.

TO THE WEATHER COMPLEXITY. RAIN CHANCES WILL INCREASE DURING MON...AS
