HYDROMETEOROLOGICAL DISCUSSION

HYDROMETEOROLOGICAL DISCUSSION:
:
DRY CONDITIONS DOMINATED THE WEATHER PATTERN ACROSS MOST THE NERFC
REGION FOR THE 24 HOUR PERIOD ENDING AT 12Z WEDNESDAY MORNING.
SOME SHOWERS AND THUNDERSTORMS BEGAN MOVING INTO FAR WESTERN NEW
YORK EARLY THIS MORNING, AS A LINGERING UPPER LEVEL LOW PRESSURE
SYSTEM OVER THE GREAT LAKES STARTED TO SPIN OFF SOME SHORTWAVES.
24-HOUR BASIN-AVERAGED PRECIPITATION TOTALS WERE GENERALLY NEAR
ZERO ACROSS THE REGION, BUT POINT TOTALS UP TO AN INCH FELL EARLY
THIS MORNING NEAR THE SOUTHERN LAKE ERIE SHORE.
:
THIS SYSTEM WILL CONTINUE TO AFFECT WESTERN NEW YORK, NORTHERN NEW
YORK, AND NORTHERN NEW ENGLAND, AS IT PROGRESSES ACROSS THE
REGION OVER THE NEXT TWO DAYS.  48-HOUR PRECIPITATION TOTALS WILL
BE GREATEST ALONG AN AXIS FROM WESTERN NEW YORK THROUGH THE
ADIRONDACKS TO NORTHERN VERMONT, AND ARE EXPECTED TO BE BETWEEN 0.
4 AND 0.6 INCHES.  TOTALS DECREASE TO THE SOUTH AND EAST, WITH
SOUTHEASTERN NEW ENGLAND AND EASTERN MAINE EXPECTING ONLY 0.1
INCHES OR LESS.
:
HYDROLOGIC DISCUSSION:
:
SHOWERS AND SOME STORMS ACROSS NEW YORK STATE AND NORTHERN NEW
ENGLAND EXPECTED TODAY WILL SUPPORT ONLY MINOR RISING RESPONSES
FOR SOME OF THE MORE RAPID RESPONDING HEADWATER BASINS. FORECAST
PRECIPITATION IS NOT SUFFICIENT FOR RISING RESPONSES AT FORECAST
LOCATIONS ACROSS SOUTHERN NEW ENGLAND PREDOMINANTLY. FORECAST
LOCATIONS ON MAINSTEM AND SLOWLY RESPONDING RIVERS ARE EXPECTED TO
CONTINUE RECEDING.
:
HIGH PRESSURE MAINTAINED DRY CONDITIONS OVER THE REGION YESTERDAY
AND OVERNIGHT LAST NIGHT. ONLY A FEW SHOWERS OCCURRED OVER BASINS
OF WESTERN NEW YORK EARLY THIS MORNING. AMOUNTS WERE NEGLIGIBLE.
THEREFORE, RIVER LEVELS CRESTED AND BEGAN TO RECEDE OR CONTINUED
TO RECEDE. THE HOUSATONIC RIVER AT GREAT BARRINGTON MASSACHUSETTS
AND FALLS VILLAGE CONNECTICUT CRESTED ABOVE ACTION LEVEL AT BOTH
LOCATIONS DURING THE PAST 24 HOURS AND ARE EXPECTED TO RECEDE FOR
THE NEXT COUPLE DAYS AT LEAST.
:
ACCORDING TO THE USGS WATERWATCH WEBPAGE, 7-DAY AVERAGE
STREAMFLOWS RELATIVE TO HISTORICALLY RECORDED FLOWS FOR YESTERDAY,
7/29 GENERALLY RANGE FROM WELL ABOVE NORMAL TO WELL BELOW NORMAL
ACROSS NEW ENGLAND AND NEW YORK STATE. ABOVE NORMAL FLOW
CONDITIONS ARE SITUATED ACROSS WESTERN AND SOUTHEASTERN NEW YORK
STATE, MOST OF VERMONT, NEW HAMPSHIRE, WESTERN MAINE AND WESTERN
PORTIONS OF SOUTHERN NEW ENGLAND. BELOW NORMAL FLOW CONDITIONS ARE
DOMINANT IN EASTERN-CENTRAL MASSACHUSETTS, EASTERN CONNECTICUT,
AND MOST OF RHODE ISLAND. ELSEWHERE, 7-DAY AVERAGE FLOW CONDITIONS
ARE THE NORMAL RANGE.
:
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.
