HYDROMETEOROLOGICAL DISCUSSION
NATIONAL WEATHER SERVICE
NORTHEAST RIVER FORECAST CENTER...TAUNTON...MA
1205 PM EDT FRI SEP 19 2014

HYDROMETEOROLOGICAL DISCUSSION:
:
A COLD FRONT WHICH MOVED ACROSS NEW YORK AND NEW ENGLAND DURING
THE PAST 24 HOURS BROUGHT SOME WIDELY SCATTERED SHOWERS TO
NORTHERN NEW YORK AND NORTHERN NEW ENGLAND. THIS RESULTED IN BASIN
AVERAGE AMOUNTS FROM NIL TO A FEW HUNDREDTHS. COOL HIGH PRESSURE
WAS BUILDING ACROSS THE NORTHEAST LATE THIS FRIDAY MORNING.
:
HIGH PRESSURE WILL CONTINUE TO BRING DRY CONDITIONS THROUGH
SATURDAY. HOWEVER THE HIGH WILL BEGIN TO PUSH OFF THE NEW ENGLAND
COAST SATURDAY AFTERNOON ALLOWING FOR WARMER AND MORE HUMID AIR TO
BE TRANSPORTED INTO THE REGION VIA SOUTHWESTERLY FLOW.
:
LOW PRESSURE FORMING OFF THE SOUTHEASTERN U.S. COAST WILL TRACK
NORTHEAST SATURDAY NIGHT AND SUNDAY. IN ADDITION A COLD FRONT WILL
ADVANCE FROM THE GREAT LAKES REGION. THESE TWO SYSTEMS ARE
EXPECTED TO REMAIN SEPARATE. SHOWERS AND ISOLATED THUNDERSTORMS
WILL BEGIN TO REACH WESTERN AND NORTHERN NEW YORK STATE...MAINE
AND EXTREME SOUTHEAST NEW ENGLAND BY SUNDAY. EVENTUALLY THE COLD
FRONT WILL SWEEP ACROSS THE REGION WITH SCATTERED TO NUMEROUS
SHOWERS AND A FEW THUNDERSTORMS EXPECTED SUNDAY AFTERNOON INTO
MONDAY MORNING.
:
48 HOUR BASIN AVERAGE PRECIPITATION TOTALS THROUGH EARLY SUNDAY
MORNING ARE FORECAST TO RANGE FROM 0.05 TO 0.25 INCH ACROSS
WESTERN AND NORTHERN NEW YORK AND NORTHERN MAINE...0.10 INCH OR
LESS ACROSS EXTREME SOUTHEAST NEW ENGLAND...AND NIL ELSEWHERE.
:
HYDROLOGIC DISCUSSION:
:
RIVER LEVELS ACROSS THE NORTHEAST REGION ARE GENERALLY IN
RECESSION OR HOLDING AT STEADY LEVELS.  THE RAIN THAT FELL IN
NORTHERN MAINE CAUSED A FEW MINOR RISES BUT THEY WERE ALL LESS
THAN 0.5 FT. RIVER WILL CONTINUE TO TREND DOWNWARD THROUGH THE
WEEKEND.
:
ACCORDING TO THE USGS WATER WATCH WEBPAGE, 7-DAY AVERAGE
STREAMFLOWS ACROSS MOST OF THE NORTHEAST REGION ARE RUNNING AT
NORMAL TO SLIGHTLY ABOVE NORMAL LEVELS FOR MID-SEPTEMBER.  HOWEVER
, ACROSS SOUTHERN NEW ENGLAND AND SOUTHEAST NEW YORK, RIVER FLOWS
ARE MOSTLY BELOW TO WELL BELOW NORMAL.
:
FLOOD OUTLOOK DISCUSSION:
:
THE NERFC FLOOD POTENTIAL OUTLOOK GRAPHIC INDICATES SIGNIFICANT
RIVER FLOODING IS NOT EXPECTED IN THE NORTHEASTERN UNITED STATES
DURING THE NEXT FIVE DAYS.
