.DISCUSSION...
/ISSUED 531 AM CDT TUE JUN 18 2013/
WELL A CHANGE TO THE FORECAST LOOKS TO BE NEEDED A LITTLE SOONER THAN
XPCTED NOW WITH THE INFLUX OF DRIER AIR ALONG THE APPROACHING FRONT
BECOMING MORE APPARENT ACROSS THE MID SOUTH REGION. ANY REDEVELOPMENT
ALONG THE FRONT HAS BEEN MINIMAL THUS FAR...ALTHOUGH SOME ADDITIONAL
SHOWERS/TSTMS ARE CERTAINLY POSSIBLE ONCE DAYTIME HEATING COMMENCES.
THE PROB THOUGH OF MULTIPLE AREAS/CLUSTERS OF HEAVY RAINFALL/TSTMS
DEVELOPING LATER TODAY IS DIMINISHING...ESPECIALLY WITH ANY LINGERING
UPPER DISTURBANCES TO THE NW SHOWING MORE OF A WEAKENING TREND OVER
THE PAST FEW HRS. AS SUCH...THE THREAT FOR ANY WIDESPREAD FLOODING
CONCERNS LATER TODAY LOOKS TO HAVE ENDED...AND LIKEWISE THE FLASH
FLOOD WATCH HAS BEEN CANCELLED. RAIN CHANCES HAVE ALSO BEEN LOWERED
SOME TODAY GIVEN A MORE PRONOUNCED SURGE OF DRIER AIR GRADUALLY
BEGINNING TO OVERSPREAD THE WRN HALF OF THE AREA. THE PROB THOUGH FOR
BRIEF HEAVY RAINFALL DEVELOPING WITHIN ANY ADDITIONAL SHOWERS/TSTMS
IS STILL PRESENT...ALTHOUGH THIS THREAT WILL LIKELY DIMINISH AS WELL
HEADING INTO THE LATE AFTERNOON PERIOD WITH THE FRONT SETTLING WELL
INTO THE AREA.
