SCATTERED LAKE EFFECT RAIN SHOWERS AND MORE LIGHT SHOWERS FROM AN
APPROACHING LOW PRESSURE SYSTEM ACROSS THE GREAT LAKES REGION
BROUGHT VERY LIGHT BASIN AVERAGE AMOUNTS UNDER 0.10 INCH ACROSS
UPSTATE NEW YORK AND NORTHERN NEW ENGLAND.

LOW PRESSURE ACROSS THE GREAT LAKES WILL MOVE ACROSS THE OHIO
VALLEY TODAY. A COUPLE OF LOW PRESSURE SYSTEMS WILL BEGIN TO TRACK
OFF THE MID ATLANTIC COAST TONIGHT AND SATURDAY NIGHT. THESE
SYSTEMS WILL SPREAD SOME SIGNIFICANT RAIN AND SNOW ACROSS EASTERN
NEW ENGLAND. THE POTENTIAL FOR ACCUMULATING SNOWFALL APPEARS TO BE
GREATEST ACROSS THE FOOTHILLS AND MOUNTAINS OF MAINE AND NEW
HAMPSHIRE AT THIS TIME.
:
48 HOUR BASIN AVERAGE FORECAST PRECIPITATION AMOUNTS RANGE FROM
0.50 TO 1.00 INCH ACROSS EXTREME EASTERN NEW ENGLAND...0.10 TO 0.

WESTERN NEW YORK...AND LESS THAN 0.10 INCH ELSEWHERE.

HYDROLOGIC DISCUSSION:
:
THE RIVERS THROUGHOUT NEW YORK AND NEW ENGLAND WERE RECEDING THIS
FRIDAY MORNING AS ANY PRECIPITATION THAT FELL OVER THE PAST 24
HOURS WAS HYDROLOGICALLY INSIGNIFICANT.
:
RAINFALL FORECAST FOR THE NEXT 48 HOURS IS EXPECTED TO CAUSE MINOR
RISES, MOSTLY LESS THAN A HALF FOOT, ALONG SOME OF THE SMALLER
RIVERS IN WESTERN NEW YORK AND EASTERN NEW ENGLAND. THE RIVERS IN
THE REST OF THE REGION WILL CONTINUE TO RECEDE FOR THE NEXT COUPLE
OF DAYS WITH LITTLE TO NO RAINFALL EXPECTED THROUGH SUNDAY
MORNING.
:
ACCORDING TO THE USGS WATER WATCH WEBPAGE, 7-DAY AVERAGE
STREAMFLOWS RELATIVE TO THOSE THAT OCCURRED IN LATE OCTOBER ARE
GENERALLY IN THE NORMAL TO WELL ABOVE NORMAL RANGES ACROSS MOST OF
NEW YORK STATE AND NEW ENGLAND.  LAST WEEK`S RAINFALL AND
INCREASED RIVER FLOWS HAVE PROVIDED FOR MANY LOCATIONS WITH WELL
ABOVE NORMAL FLOWS SITUATED ACROSS MASSACHUSETTS, SOUTHERN NEW
HAMPSHIRE AND CENTRAL TO SOUTHERN MAINE.  A FEW LOCATIONS IN
