A strong upper atmospheric low pressure system moved from south central Canada to the Great Lakes during the night of December 20th into the morning of December 21st. At the surface, the primary low associated with this upper level feature moved into the Great Lakes and weakened on the  21st. Meanwhile, a secondary coastal low developed off the Mid-Atlantic coast during the morning of the 21st and tracked into the Gulf of Maine during that evening.
Snow overspread Vermont around daybreak on the 21st and fell heavy at times during the late morning and early afternoon hours before dissipating during the evening. Snowfall accumulations of 6 to 10 inches were common across western Vermont with 10 to 18 inches across central and eastern Vermont. Some specific snowfall totals include; 18 inches in Marshfield (Washington), St. Johnsbury (Caledonia county), Rochester (Windsor county) and Randolph Center (Orange county) with 15 inches in Moretown and Waterbury Center (Washington county), North Promfret (Windsor county), Island Pond (Essex county).
This was the second significant snowfall within 36 hours which led to additional vehicle accidents and exhausted snow removal resources. Snowfall totals in excess of 24 inches within 36 hours led to blocked ventilation pipes and some carbon monoxide injuries as well as a few collapsed small farm structures due to the weight of the snow.
