TROUGH EXTENDS FROM LAKE ONTARIO EAST AND SOUTHEAST INTO
SOUTHWEST CONNECTICUT. THIS TROUGH WILL BE THE FOCUS FOR SOME
SNOWSHOWERS THIS AFTERNOON ACROSS INTERIOR NEW YORK STATE AND
INTERIOR SOUTHERN NEW ENGLAND. TONIGHT...LOW LEVEL CONVERGENCE
ALONG THE TROUGH WILL INTENSIFY AND LIKELY BRING A STEADIER PERIOD
OF SNOW TO COASTAL SECTIONS OF NEW HAMPSHIRE AND EASTERN
MASSACHUSETTS WITH SOME RAIN MIXED IN ACROSS OUTER CAPE COD. BASIN
AVERAGE MELTED EQUIVALENT PRECIPITATION OVER THE NEXT 48 HOURS
SHOULD BE MAXIMIZED WITH THIS SURFACE TROUGH FROM BOSTON SOUTHEAST

TWO FEET OR LESS WERE SEEN IN SOUTHERN NEW ENGLAND. SMALLER RISES
WERE SEEN TO THE NORTH AND WEST...WHERE THE PRECIPITATION FELL
MOSTLY AS SNOW.

ACCORDING TO THE USGS WATER WATCH WEBPAGE...7-DAY AVERAGE
STREAMFLOWS ACROSS THE NERFC REGION ARE GENERALLY NORMAL TO BELOW
NORMAL FOR LATE NOVEMBER. EXCEPTIONS TO THIS TREND ARE IN WESTERN

RAINFALL AND THE MELTING OF THE LAKE EFFECT SNOW EARLIER THIS WEEK
