A strong cold front crossed the region on New Year���s Day. A broad area of lake effect snows develop along the south shores of Lakes Erie and Ontario late on the first. Some narrow intense bands developed in this area and extended up to twenty miles inland. The activity continued through Saturday (3rd) and then strengthened in place Saturday Night as a large area of moisture spiraled around a massive coastal storm off New England.  A general burst of moderate to heavy snow accompanied this synoptic feature as it dropped south and southwest across the entire region during Sunday, then finally the lake effect weakened and retreated to near the lakes again Sunday night.  This event was unique in many ways, most notably in the large amounts of snow off Lake Ontario back across much of the Niagara frontier. A general one to two feet fell over two days, with up to 30 inches around Niagara Falls. Another area of very heavy snow focused on Wayne to Oswego County where two to three feet fell. The Rochester area caught a bit less, but still up to 18 inches near the Lake.  Off Lake Erie, two feet or more fell near Chautauqua Lake from Mayville to Jamestown.
Specific snowfall totals Off Lake Erie included:  Mayville 31���; Jamestown 28���; and Perrysburg 26���. Off Lake Ontario, the reports included: 42��� at Fulton; 38��� at Lacona; 36��� at Marion; 34��� at Scriba; 32��� at Hannibal; 31��� at Niagara Falls; 30��� at Pulaski; 26��� at North Tonawanda, Kent and Williamson; 24��� at Lockport; 22��� at Oswego; 19��� at North Amherst; 16��� at Perry; 14��� at Tonawanda; and 9��� to 18��� in Rochester (from north to south across the city).
