.DISCUSSION...
THE MS AND TN VALLEY IS IN BETWEEN HIGH PRESSURE OFF IN THE ATLANTIC
AND A TROUGH MOVING IN FROM THE MIDWEST. WV SHOWS A MOISTURE PLUME
OVER LA AND MS AHEAD OF THE TROUGH. A SMALL DISTURBANCE MOVING
THROUGH PROVIDED THE FEW SHOWERS SEEN AROUND THIS AREA THIS MORNING.
OTHERWISE THE MAJORITY OF THE PRECIP HAS STAYED TO OUR WEST THUS
FAR.

WITH THE SUN PEEKING OUT IN A FEW LOCATIONS...THIS WILL ALLOW FOR
ASSISTANCE IN INSTABILITY THIS AFTERNOON. CURRENT OBS SHOW DEW
POINTS IN THE HUN CWA HAVE IMPROVED AND ARE NOW AROUND 7O. SOUTHERLY
FLOW WILL CONTINUE THROUGHOUT THE DAY AND IS SEEN THROUGHOUT THE
SOUNDING. PULLING IN THE GULF MOISTURE...PWATS ARE AROUND 2 INCHES.
CAPE VALUES COULD GET UP TO 1000 TO 15000 J/KG AROUND THE TN VALLEY
THIS AFTERNOON. THE MAIN SHORT WAVE WILL MOVE IN LATER THIS
AFTERNOON/EVENING. AT THIS TIME...WOULD STILL BE LOOKING AT GUSTY
WINDS AND HEAVY DOWNPOURS TO OCCUR WITH STORMS AS THEY MOVE ACROSS
THE AREA.

AS FOR CHANGES IN THE GRIDS...LOWERED POPS FOR THIS MORNING AS WE
SEEMED TO BE TOO DRY AND STABLE TO GET ANY PRECIP TO MOVE EASTWARD
INTO OUR AREA. ALSO SLIGHTLY DECREASED CLOUD COVER FOR THIS MORNING AS
WELL. INCREASED TEMPS BY A DEGREE AS THE COULD COVER IS NOT AS THICK
AS EXPECTED THIS MORNING. ALSO ADJUSTED THE WINDS FOR CURRENT TRENDS.
