HYDROMETEOROLOGICAL DISCUSSION
NATIONAL WEATHER SERVICE
NORTHEAST RIVER FORECAST CENTER...TAUNTON...MA
1154 AM EDT SAT OCT 25 2014

HYDROMETEOROLOGICAL DISCUSSION:
:
THE COASTAL STORM THAT IMPACTED THE NORTHEAST THE PAST SEVERAL
DAYS HAS FINALLY DEPARTED THE NORTHEAST. A COLD FRONT WILL BEGIN
TO MOVE ACROSS STARTING IN WESTERN NEW YORK LATER TODAY AND MOVING
ACROSS THE NORTHEAST OVER THE NEXT COUPLE OF DAYS.
:
RAINFALL DURING THE PAST 24 HOURS WAS HEAVIEST IN MAINE ALTHOUGH
AMOUNTS WERE MUCH LESS THAN THE PREVIOUS COUPLE OF DAYS.  ONLY A
FEW REPORTS OF OVER A HALF AN INCH WERE OBSERVED IN FAR NORTHERN
MAINE. OTHER PARTS OF MAINE WERE LESS THAN 0.25 INCHES.  THE REST
OF THE NORTHEAST HAD ZERO OR ONLY VERY LIGHT AMOUNTS OF RAIN.
:
OVER THE NEXT COUPLE OF DAYS AS THE COLD FRONT MOVES ACROSS UP TO
ABOUT 0.5 INCHES OF RAIN IS POSSIBLE ACROSS PARTS OF NORTHERN NEW
YORK AND NEW ENGLAND.  SOME OF HIGHER ELEVATIONS COULD SEE SOME
SNOW SHOWERS WITH THIS PRECIPITATION. MOST OF SOUTHERN NEW ENGLAND
WILL BE DRY OVER THE NEXT SEVERAL DAYS.
:
HYDROLOGIC DISCUSSION:
:
LOW PRESSURE MOVES AWAY FROM MAINE TODAY AS A WEAK RIDGE PASSES
OVER THE REGION AND A COLD FRONT APPROACHES FROM THE WEST.
PRECIPITATION FORECAST OVER THE NEXT COUPLE DAYS IS EXPECTED TO BE
GREATEST INTO NEW YORK STATE AND NORTHERN NEW ENGLAND. HOWEVER,
AMOUNTS WILL PROVIDE FOR NO MORE THAN MINOR RISES UNDER A FOOT.
FORECAST LOCATIONS FOR THE MORE SLOWLY RESPONDING TRIBUTARY AND
MAINSTEM RIVER LOCATIONS WILL CONTINUE RISING OR WILL CREST AND
BEGIN TO RECEDE TODAY. HEADWATER AND THE MOST RAPIDLY RESPONDING
TRIBUTARY RIVERS WILL CONTINUE TO RECEDE.
:
RISING RIVER RESPONSES CONTINUED AT LEAST DURING SOME OF THE DAY
YESTERDAY AT MANY RIVER FORECAST LOCATIONS ACROSS THE LAKE
CHAMPLAIN VALLEY AND NEW ENGLAND. FORECAST LOCATIONS WHERE RIVERS
CONTINUE TO RISE AS OF 8AM THIS SATURDAY MORNING INCLUDE THE ST.
JOHN RIVER AT DICKEY AND FORT KENT, ME, THE AROOSTOOK RIVER AT
MASARDIS AND WASHBURN, ME, THE MATTAWAMKEAG RIVER NEAR
MATTAWAMKEAG, ME, THE MERRIMACK RIVER AND THE CONCORD RIVER AT
LOWELL, MA, THE CONNECTICUT RIVER AT DALTON, NH, AND THE CHARLES
RIVER AT DOVER, MA. ELSEWHERE RIVERS CRESTED AND/OR CONTINUED TO
RECEDE. RECEDING TRENDS VARIED ACROSS THE REGION FROM RAPIDLY TO
SLOWLY AT FORECAST LOCATIONS.
:
ACCORDING TO THE USGS WATER WATCH WEBPAGE... 7-DAY AVERAGE
STREAMFLOWS RELATIVE TO THOSE THAT OCCURRED HISTORICALLY FOR
FRIDAY, 10/24 ARE IN THE NORMAL TO WELL ABOVE NORMAL RANGES ACROSS
MOST OF NEW YORK STATE AND NEW ENGLAND. RECENT RAINFALL AND
INCREASED RIVER FLOWS HAVE PROVIDED FOR MANY ADDITIONAL LOCATIONS
WITH WELL ABOVE NORMAL FLOWS SITUATED ACROSS MASSACHUSETTS,
SOUTHERN NEW HAMPSHIRE AND PORTIONS OF MAINE. ONLY A FEW LOCATIONS
IN SOUTHERN RHODE ISLAND AND SOUTHEASTERN CONNECTICUT RECORDED
WEEKLY AVERAGE STREAMFLOWS BELOW NORMAL LEVELS.
