A LINGERING UPPER LEVEL TROUGH BROUGHT MORE SCATTERED SHOWERS TO
NEW YORK AND NEW ENGLAND DURING THE PAST 24 HOURS. SOME OF THIS
ACTIVITY WAS LOCALLY HEAVY. 24 HOUR BASIN AVERAGE AMOUNTS ENDING
8AM THIS SATURDAY MORNING RANGED FROM A TRACE UP TO 0.50 INCH
ACROSS PORTIONS OF CENTRAL AND EASTERN NEW YORK AND WESTERN NEW
ENGLAND. SOME LOCALLY HIGHER POINT TOTALS ABOVE ONE INCH WERE
NOTED.
:
ANOTHER UPPER LEVEL DISTURBANCE CROSSING UPSTATE NEW YORK TODAY
WILL BRING WIDELY SCATTERED SHOWERS TO NEW YORK STATE AND WESTERN
NEW ENGLAND TODAY...PARTICULARLY ACROSS THE HIGHER TERRAIN. HIGH
PRESSURE AT THE SURFACE AND ALOFT WILL GRADUALLY BUILD ACROSS THE
REGION SUNDAY THROUGH MIDWEEK AND WILL ALLOW DRY CONDITIONS TO
PREVAIL.

48 HOUR BASIN AVERAGE PRECIPITATION AMOUNTS ARE FORECAST TO RANGE
FROM 0.10 INCH OR LESS.

HYDROLOGIC DISCUSSION:
:
GIVEN THAT CONDITIONS GENERALLY ARE EXPECTED TO REMAIN WITHOUT
PRECIPITATION DURING THE NEXT COUPLE DAYS, RIVER LEVELS WILL TREND
LOWER OR REMAIN NEARLY STEADY INTO MONDAY.
:
SHOWERS AND WIDELY SCATTERED POCKETS OF MODERATE TO HEAVY RAINFALL
YESTERDAY AFTERNOON AND EVENING RESULTED IN MINOR ADDITIONAL
RIVER RESPONSES OF LESS THAN A FOOT OVERNIGHT. THIS RAINFALL
OCCURRED MAINLY OVER THE EASTERN FINGER LAKES AND NORTHWESTERN NEW
YORK STATE AS WELL AS NORTHERN VERMONT. WITH NEGLIGIBLE OR NO
RAINFALL OCCURRING ELSEWHERE, RIVER LEVELS CONTINUED TO DECLINE OR
HOLD NEARLY STEADY AT FORECAST LOCATIONS. FLUCTUATIONS IN RIVER
LEVELS OF SEVERAL FEET OCCURRED FOR SOME LOCATIONS INFLUENCED BY
THE TIDAL CYCLE OR DAM OPERATIONS.
:
FROM THE USGS WATERWATCH WEB PAGE, 7-DAY AVERAGE STREAMFLOWS
COMPARED WITH HISTORICALLY RECORDED FLOWS FOR YESTERDAY, 8/22 ARE
GENERALLY NORMAL TO MUCH ABOVE NORMAL ACROSS OF NEW YORK STATE AND
NEW ENGLAND. ONLY A FEW LOCATIONS IN SOUTHEASTERN NEW YORK STATE,
SOUTHEASTERN MASSACHUSETTS, SOUTHERN RHODE ISLAND AND SCATTERED
