CONTINUE TO MOVE SOUTH ACROSS THE CENTRAL GULF STATES THIS MORNING
ALONG AND AHEAD OF A COLD FRONT LOCATED OVER NORTHERN SECTIONS OF THE
CWFA THIS MORNING THAT IS PROGGED TO ADVANCE SOUTH TO THE IMMEDIATE
COAST BY AROUND 12Z THIS MORNING. FURTHER UPSTREAM TO THE WEST AND
NORTHWEST MORE SHOWERS WERE OCCURRING GENERALLY MOVING EAST SOUTHEAST
TOWARDS THE LOWER MS RIVER VALLEY AND CENTRAL GULF COAST REGION.
ALOFT A SERIES OF WEAK MID LEVEL IMPULSES WELL TO THE WEST AND
NORTHWEST WILL CONTINUE TO TO TRACK EASTWARD AND DAMPEN STILL LEADING
TO MARGINAL FORCING FURTHER TO THE EAST AND SOUTH THROUGH MID
MORNING...HELPING TO GENERATE THE SHOWERS ACROSS CENTRAL AND LOWER
PARTS OF THE CWFA THROUGH ABOUT MID MORNING...THEN SHIFTING FURTHER
TO THE SOUTH AND EAST BY LATE MORNING. LATEST LAPS AND SPC
MESOANALYSIS CONTINUE TO SHOW MARGINAL INSTABILITY COMBINED WITH
GOOD LOW LEVEL VERTICAL SHEAR GENERALLY FROM 0-1KM ACROSS MOST OF THE
REGION THIS MORNING WHICH ALSO CONTINUES TO HELP GENERATE THIS
MORNINGS SHOWERS. BY LATE THIS MORNING SKIES SHOULD ALSO BEGIN TO
CLEAR FROM NORTH TO SOUTH RESULTING IN MOSTLY SUNNY SKIES FOR MOST OF
THE CWFA BY EARLY TO MID AFTERNOON. WITH THE BETTER SUNSHINE EXPECTED
BY THIS AFTERNOON FOR MOST AREAS WILL CONTINUE TO LEAN TOWARDS THE
WARMER MAV GUIDANCE FOR HIGH TEMPS THROUGH THIS AFTERNOON...THEN THE
COOLER MET GUIDANCE OVERNIGHT DUE TO MOSTLY CLEAR SKIES EXPECTED

SHORTWAVES MOVE ACROSS THE SOUTHEAST STATES. A SURFACE HIGH CENTERED OVER
THE EAST CENTRAL STATES MOVES OFF INTO THE ATLANTIC ON SUNDAY
ALLOWING FOR A RETURN FLOW TO ENSUE OVER THE FORECAST AREA. DEEP
LAYER MOISTURE INCREASES QUICKLY AND SIGNIFICANTLY THROUGH SUNDAY
NIGHT WITH THE RETURN FLOW WITH PRECIPITABLE WATER VALUES INCREASING
FROM NEAR 0.6 INCHES TO 1.6 INCHES...WITH JUST A MODEST DECREASE
THROUGH MONDAY NIGHT AS UPPER RIDGING BEGINS TO BUILD INTO THE
