What happened

The episode as NWS BTV wrote it up.

An upper level disturbance helped initiate the development of a weak surface low along a frontal boundary, all of which moved across Vermont during the night of December 11th and into the morning hours of the 12th. A wintry mix of snow, sleet and freezing rain overspread Vermont during the evening hours of the 11th but changed to accumulating snow during the early morning hours of the 12th before ending by mid-morning. Combined snow and sleet accumulations across Vermont were 2 to 5 inches. Some specific accumulations included; 5 inches in North Underhill (Chittenden county), 4 inches in Wheelock (Caledonia county), St. Albans (Franklin county), Morrisville (Lamoille county) and East Albany (Orleans county) with 3 inches in Marshfield (Washington county), West Topsham (Orange county) and South Lincoln (Addison county).
