EXCESSIVE RAINFALL DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
934 PM EDT TUE APR 15 2014

...VALID 03Z WED APR 16 2014 - 00Z THU APR 17 2014...
...REFERENCE AWIPS GRAPHIC UNDER...DAY 1 EXCESSIVE RAINFALL...


SLIGHT RISK OF RAINFALL EXCEEDING FFG TO THE RIGHT OF A LINE FROM
10 NNW CYSL 30 ESE CAR 30 WNW CWZF 25 NNE CWSS 10 SSW CWSS
25 SW CWSS 25 N BHB 10 S BGR 25 E WVL WVL 20 NW WVL 35 NNW WVL
25 NW GNR 30 W FVE 10 NNW CYSL.


TRIMMED DOWN THE PREVIOUS THREAT AREA..WITH COLD AIR COMING INTO
NEW ENGLAND AND THE RAINS CHANGING OVER TO SNOW..BUT DID KEEP THE
SLIGHT RISK IN EASTERN PORTIONS OF ME WHERE PRECIPITATION SHOULD
CONTINUE AS RAIN PAST MIDNIGHT AND FF GUIDANCE VALUES ARE QUITE
LOW IN SOME LOCATIONS.  THE STRONG SYNOPTIC SCALE FORCING
ASSOCIATED WITH THE APPROACHING AND AMPLIFYING H5 TROF SUGGEST
THAT LIGHT TO MODERATE RAINFALL WILL BE MOST COMMON WITHIN THE
PRECIPITATION SHIELD..AND COULD CAUSE SOME ISOLATED ADDITIONAL
FLOODING CONCERNS WHERE FF GUIDANCE VALUES ARE LOWEST.
