HYDROMETEOROLOGICAL DISCUSSION:
:
AN UPPER LEVEL LOW BROUGHT SCATTERED SHOWERS ACROSS NORTHERN MAINE
ON THURSDAY. 24 HOUR BASIN AVERAGE AMOUNTS WERE GENERALLY VERY
LIGHT...NIL TO LESS THAN 0.05 INCH ACROSS THIS REGION.
:
HIGH PRESSURE WILL COVER MOST OF NEW YORK AND NEW ENGLAND THROUGH
SATURDAY. LOW PRESSURE WILL APPROACH FROM THE GREAT LAKES LATE
SATURDAY AND SUNDAY. THIS SYSTEM WILL BRING SCATTERED SHOWERS AND
THUNDERSTORMS TO WESTERN AND NORTHERN NEW YORK AND NORTHERN MAINE
LATE SATURDAY AND SUNDAY MORNING. THIS ACTIVITY WILL SPREAD ACROSS
THE REMAINDER OF NEW YORK AND NEW ENGLAND SUNDAY AFTERNOON AND
MONDAY.
:
48 HOUR BASIN AVERAGE PRECIPITATION TOTALS FORECAST THROUGH EARLY
SUNDAY RANGE FROM 0.05 TO 0.25 INCH ACROSS WESTERN NEW YORK AND
NORTHERN MAINE. SOME LOCALLY HIGHER POINT TOTALS WILL BE POSSIBLE
.
:
HYDROLOGIC DISCUSSION:
:
RAINFALL FORECASTS OF LESS THAN 0.25 INCH PRODUCE NEGLIGIBLE RIVER
LEVEL RESPONSE IN FORECASTS DURING THE NEXT FEW DAYS. INSTEAD
RIVER LEVELS WILL CONTINUE TO DECLINE OR REMAIN NEARLY STEADY FOR
MOST IF NOT ALL FORECAST LOCATIONS. WHERE LOCALLY HEAVY DOWNPOURS
INTERSECT SMALL STREAMS AND HEADWATER BASIN AREAS, THERE IS
POTENTIAL FOR MINOR TO SMALL RISING RESPONSES.
:
GENERALLY VERY LIGHT RAINFALL OVER NORTHERN MAINE YESTERDAY
AFTERNOON AND EVENING WAS NOT ENOUGH TO RESULT IN RISING RIVER
RESPONSES. RIVERS AT FORECAST LOCATIONS CONTINUED TO DECLINE OR
HOLD NEARLY STEADY YESTERDAY AND OVERNIGHT. FLUCTUATIONS IN RIVER
LEVELS AS MUCH AS SEVERAL FEET AT SOME FORECAST LOCATIONS RESULT
FROM POWER GENERATION, RESERVOIR REGULATION AND/OR TIDAL INFLUENCE
.
:
FROM THE USGS WATERWATCH WEB PAGE, 7-DAY AVERAGE STREAMFLOWS
RELATIVE TO HISTORICAL STREAMFLOWS FOR YESTERDAY, 8/28 GENERALLY
ARE WITHIN THE NORMAL TO MUCH ABOVE NORMAL CATEGORIES ACROSS THE
MAJORITY OF NEW YORK STATE AND NEW ENGLAND. BELOW NORMAL FLOWS
EXIST FOR A FEW LOCATIONS IN FAR SOUTHEASTERN NEW YORK STATE,
SOUTHEASTERN MASSACHUSETTS, CONNECTICUT AND RHODE ISLAND.
:
FLOOD OUTLOOK DISCUSSION:
