The episode as NWS BTV wrote it up.
Surface low pressure across the Ohio River Valley on April 26th slowly moved across the southern New England coast into the Gulf of Maine on the 27th and 28th. Meanwhile, a cold, strong upper atmospheric area of low pressure moved from Quebec across northern New England.
This resulted in an abnormally cold, unstable and moist air mass across northern New York which produced largely orthographically enhanced snowfall across the higher terrain of the northern Adirondacks, northern Champlain Valley and northern St. Lawrence River Valley.
The snow began by daybreak on the 27th and slowly diminished during the morning of the 28th with accumulations of a heavy, wet snow that ranged from 4 to 8 inches in the valleys with 8 to 20 inches above 1000 feet in favored northwest facing slope communities. This heavy wet snowfall resulted in scattered power outages that affected over 5000 customers.
Some specific snowfall totals included; 5 inches in Potsdam (St. Lawrence county), 7 inches in Champlain (Clinton county) and Childwold (St. Lawrence county), 9 inches in Lake Placid (Essex county), 14 inches in South Colton (St. Lawrence county) and Malone (Franklin county) with 16 inches at Lyon Mountain (Clinton county), 18 inches at Chasm Falls (Franklin county) and 19.5 inches in Dannemora (Clinton county).
