The fourth lake effect event of the winter season followed on the heels of storm which brought a cold rain to most of the area. The event was long lasting and featured three ���sub��� events. Most of the accumulation occurred during these three sub event periods, a north to northwest upslope flow from late Monday the 13th through Tuesday morning the 14th which brought six to ten inches from Monroe to Wayne county and over a foot to the Chautauqua ridge; a rare narrow but intense band from Georgian Bay which worked slowly across the Niagara frontier during afternoon of Tuesday 14th dropping 4 to 7 inches; and a broader west northwest flow off the east end of Lake Ontario on Wednesday night and Thursday morning the 15th-16th dropped over a foot of snow over Oswego county. Again, lighter activity continued outside of these periods but accumulating snow fell at least until Friday. The four-day totals topped two feet over much of Wayne and Oswego counties and over a foot back across Greater Rochester as well as over some higher elevations south of Buffalo.
Off Lake Erie, storm totals included: 22 inches at Perrysburg; 16 inches at Randolph; 14 inches at Hinsdale; and 12 inches at Boston and Buffalo.  Off Lake Ontario, reported totals included: 35 inches at Lacona; 30 inches at Fulton; 28 inches at Walworth; 25 inches at Pulaski; 23 inches at Marion and 18 inches at Rochester.
