Lake snows persisted as a deep trough of low pressure became entrenched across the northeast United States.
Off Lake Erie, a band of lake effect snow developed along the Lake Erie shoreline Monday (21st) producing very heavy snow and difficult travel along the New York State Thruway corridor from Hamburg to the Pennsylvania State Line. Snowfall rates during this time reached about two inches per hour. From Tuesday through Thursday, multiple bands of somewhat lighter lake effect snow continued across much of the Southern Tier and occasionally drifted into southern Erie and Wyoming counties. The greatest totals off Lake Erie were found in southwest Chautauqua County and along the Chautauqua ridge where snow totals were near two feet. Specific snowfall reports included:  25 inches at Perrysburg and Ripley, 21 inches at Forestville, 18 inches at Glenwood, 16 inches at West Valley, 13 inches at Warsaw and 12 inches at Collins.
Off Lake Ontario, an intense band of lake effect snow developed east of the lake late Monday Night across the Tug Hill region and drifted slowly south across Oswego County on Tuesday producing more heavy snow along the way. Snowfall rates reached three to five inches per hour during this time. The band then settled along the south shore of the lake Tuesday Night with heavy snow along the entire south shore. Periodic bands of somewhat weaker lake effect snow then continued along the south shore of the lake through midweek. The greatest totals off Lake Ontario were found over Oswego County ��� nearing two feet. About a foot fell along much of the south shore within a few miles of the lake from Eastern Niagara County to Wayne County.  Specific snowfall reports included:  22 inches at Palermo and Phoenix, 20 inches at Fulton, 18 inches at Fair Haven, 15 inches at Osceola, 13 inches at Lyndonville, 12 inches at Sodus, 11 inches at Hamlin Beach, 10 inches at Newfane.
