What happened
The episode as NWS BUF wrote it up.
A complex system moved into the area with wildly varying thermal profiles. An initial mid-level trough and surface low moved across the southeast United States that gave way to secondary cyclogenesis near the southern tip of the Delmarva. The secondary low then moved northward along the east coast to the Gulf of Maine. The system had very marginal cold air to work with, particularly in western New York. As the event unfolded, precipitation type was mostly snow from Rochester eastward, with just a few brief periods of sleet. More sleet and some freezing rain mixed in through the first half of the event across far western New York, cutting back on snow accumulation there. Snow accumulations included 10 inches in Williamson, 15 inches in Port Byron, 15 inches in Bennets Bridge, 15 inches in Beaver Falls, 14 inches in Warsaw, 11.5 inches in Lima, 8.3 inches in Perrysburg, 12 inches in Andover, 12 inches in Bristol, 10 inches in Concord, and 12 inches in Pittsfield.
