.DISCUSSION...
/ISSUED 225 PM CST TUE DEC 1 2015/
THE 20Z SURFACE ANALYSIS INDICATED THAT THE SURFACE LOW WAS MOVING
ACROSS MINNESOTA WITH A COLD FRONT EXTENDING BACK FROM THE GREAT
LAKES REGION THROUGH THE OHIO AND TENNESSEE VALLEY REGION. THE COLD
FRONT WAS CONTINUING TO BE THE FOCUSING MECHANISM FOR OVERRUNNING
PRECIP ACROSS THE FORECAST AREA. THE ANALYZED LOCATION OF THE COLD
FRONT THROUGH THE FORECAST AREA AT 20Z HAD IT GENERALLY ALONG AND
SLIGHTLY WEST OF INTERSTATE 65 ACROSS THE AREA. TEMPS WERE RANGING
FROM THE LOWER 60S ACROSS NORTHEAST ALABAMA...TO THE LOW TO MID 50S
FROM HSV TO MSL.

IN THE SHORT TERM TONIGHT...HAVE CANCELLED THE FLOOD WATCH FOR
SOUTHERN MIDDLE TENNESSEE...AS THE BULK OF THE HEAVIER PRECIP IS NOW
MAINLY SOUTH OF THE TENNESSEE RIVER IN NORTHERN ALABAMA. EXPECT SOME
MAINLY LIGHT PRECIP TO CONTINUE THIS EVENING ACROSS SOUTHERN MIDDLE
TENNESSEE...BUT NOT ENOUGH TO WARRANT CONTINUING THE FLOOD WATCH.
WILL CONTINUE THE FLOOD WATCH TONIGHT UNTIL 12Z WEDNESDAY FOR
MADISON...JACKSON...MARSHALL AND DEKALB COUNTIES IN NORTH CENTRAL AND
NORTHEAST ALABAMA DUE TO THE EXPECTED SLOW EASTWARD MOVEMENT OF THE
LARGE AREA OF PRECIP ALONG THE BOUNDARY ACROSS THE AREA.

THE SHORT TERM MODELS ARE IN GOOD AGREEMENT INVOLVING THE UPPER LOW
MOVING EASTWARD ACROSS THE GREAT LAKES REGION...WHICH SHOULD AID IN
MOVING THE SLOW MOVING FRONTAL BOUNDARY FINALLY EASTWARD THROUGH THE
REGION ON WEDNESDAY. WILL BE ENDING THE PRECIP FROM WEST TO EAST
ACROSS THE FORECAST AREA ON WEDNESDAY AND EXPECT SLOW CLEARING ACROSS
NORTHWEST ALABAMA BY 18Z WEDNESDAY THROUGH THE AFTERNOON. HAVE
REMOVED PRECIP CHANCES ACROSS THE AREA AFTER 21Z IN NORTHEAST
ALABAMA DUE TO EXPECTED DRIER AIR IN LOW-MID LEVELS MOVING IN.

COLD ADVECTION WILL CONTINUE TO MOVE INTO THE TENNESSEE VALLEY REGION
ON WEDNESDAY NIGHT IN THE WAKE OF THE UPPER LOW MOVING INTO THE
NORTHEAST U.S. WILL LOWER TEMPS SLIGHTLY ON WEDNESDAY NIGHT DUE TO
WINDS BECOMING LIGHT AND VARIABLE AND CLEAR SKIES OCCURRING. A LARGE
AREA OF HIGH PRESSURE WILL MOVE INTO THE REGION BY EARLY THURSDAY
AND MAINTAIN CONTROL OF THE WEATHER ACROSS THE AREA THROUGH SUNDAY
WITH DRY WEATHER AND A SLOW WARMING TREND OCCURRING. TEMPS SHOULD
RISE TO SLIGHTLY ABOVE NORMAL LEVELS ACROSS THE FORECAST AREA FROM
FRIDAY THROUGH SUNDAY.

A DEVELOPING UPPER LEVEL LOW ACROSS THE CENTRAL PLAINS STATES ON
SUNDAY WILL GET SHIFTED EASTWARD IN THE STRONG UPPER LEVEL FLOW INTO
THE LOWER OHIO VALLEY REGION BY 12Z MONDAY. HAVE MAINTAINED A SLIGHT
CHANCE/CHANCE POP FROM EARLY MONDAY THROUGH TUESDAY TO ROUND OUT THE
EXTENDED FORECAST PERIOD.
