EXCESSIVE RAINFALL DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
158 PM EST WED DEC 24 2014

...VALID 18Z WED DEC 24 2014 - 00Z FRI DEC 26 2014...
...REFERENCE AWIPS GRAPHIC UNDER...DAY 1 EXCESSIVE RAINFALL...


...NORTHERN NJ INTO EASTGERN NEW ENGLAND...

THE DEEP LAYERED SOUTHERLY FLOW PATTERN AHEAD OF THE HIGH
AMPLITUDE MID/UPPER TROF WILL CONTINUE TO DRAW UNSEASONABLY DEEP
MSTR NORTHWARD UP THE EAST COAST..LEADING TO WIDESPREAD WARM AIR
ADVECTION RAINS..WITH SOME ENHANCEMENT TO THE RAINS PROBABLE ALONG
AND JUST AHEAD OF THE COLD FRONTAL PASSAGE.  SOME TRAINING OF
MODERATE TO ISOLATED HEAVIER BANDS OF RAIN COULD LEAD TO SOME VERY
LOCAL RUNOFF PROBLEMS MAINLY FROM NORTHERN NJ INTO EASTERN NEW
ENGLAND..BUT WITH THE MORE ORGANIZED CONVECTIVE POTENTIAL
REMAINING WELL TO THE SOUTH OF NEW ENGLAND..SEE THIS AS A DURATION
RAINFALL EVENT PROBLEM.  SOME VERY ISOLATED 1 INCH RAINS IN A
COUPLE OF HOURS POSSIBLE..WHICH COULD LEAD TO SOME RUNOFF CONCERNS.
