The episode as NWS BUF wrote it up.
A rapidly deepening storm system moved eastward from Lake Huron and tracked north of Lake Ontario to southwestern Quebec. The system was followed by a westerly flow of very cold air across the still unfrozen Great Lakes which triggered lake effect snows downwind of both lakes.|Off Lake Erie, a narrow but intense band of lake effect snow across Chautauqua and Cattaraugus Counties. Winds then backed to west-southwest and the band lifted north bringing lake snows into southern Erie and Wyoming Counties. As an upper level shortwave trough moved through, the snow shifted back south before an approaching system again brought the snows further north across the Buffalo metro area. Snowfall rates varied from one to as much as three inches of snow per hour. The greatest snow totals off Lake Erie fell across the Southern Tier where narrow but intense bands of snow brought localized amounts of over two feet of snow. Significant snows over one foot also fell across Grand Island and southern Niagara County. Much of the Greater Buffalo area had a large gradient in snow totals ranging from 3 inches to around a foot due to the transient nature of the band on Saturday morning.|Off Lake Ontario, lake snows organized into a narrow but intense band of snow over southern Jefferson County as winds aligned down the long axis of the lake. This band sagged south across central Oswego County where snowfall rates of up to 2 inches per hour were observed. The lake band briefly pushed south over the southern shore of Lake Ontario with heavier lake snows making for a messy morning commute in the Rochester metro area. The band then lifted north into Jefferson County with heavy snow for the Watertown area. Some of the highest snowfall rates of this event were observed across northern Jefferson County with three to four inches per hour falling. The greatest snow totals off Lake Ontario fell during two periods. During the first, six to as much as twenty-one inches were measured in central Oswego and southern Lewis Counties. During the second, six to sixteen inches were measured across northern Jefferson County.
