EXCESSIVE RAINFALL DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
934 AM EDT SUN SEP 14 2014

...VALID 15Z SUN SEP 14 2014 - 12Z MON SEP 15 2014...
...REFERENCE AWIPS GRAPHIC UNDER...DAY 1 EXCESSIVE RAINFALL...


SLIGHT RISK OF RAINFALL EXCEEDING FFG TO THE RIGHT OF A LINE FROM
30 SE HXD 15 SSE LHW 25 ENE AMG 10 NNW AMG 25 N DQH 20 ESE EZM
25 NNE VDI 15 ENE JYL CHS 50 E CHS 65 S MYR 75 ESE CHS 30 SE HXD.

MADE SOME CHANGES TO THE PREVIOUS ISSUANCE..MAINLY TO REMOVE THE
MODERATE RISK AND SHRINK THE SLIGHT RISK.  SOME HEAVY TO EXCESSIVE
RAINS STILL POSSIBLE IN THE VICINITY OF THE SURFACE FRONT EXPECTED
TO REMAIN QUASI-STATIONARY THIS PERIOD ACROSS THE SOUTHEASTERN
U.S. FROM THE FL PANHANDLE INTO THE SOUTHEAST GA AND COASTAL SC.
ABOVE AVERAGE PW VALUES---1.5 TO 2 STANDARD DEVIATIONS ABOVE THE
MEAN---ARE EXPECTED TO PERSIST IN THE VICINITY OF THIS
BOUNDARY---ESPECIALLY FROM SOUTHEAST GA INTO COASTAL SC.  LARGE
SCALE LIFT PROBABLY NOT AS FAVORABLE AS YESTERDAY/LAST NIGHT..BUT
THE SLOW MOVING CELLS IN THE VERY HIGH PW AIRMASS COULD STILL
SUPPORT THE POTENTIAL FOR HEAVY TO ISOLATED EXCESSIVE RAINFALL
AMOUNTS.  IN AREAS OF THESE SLOW MOVING CELLS---ISOLATED SHORT
TERM AMOUNTS OF 2 TO 4 INCHES WILL BE POSSIBLE.
