A closed upper level low across te Great Lakes on April 15th moved over the NYC vicinity on January 16th. A secondary surface low formed off the Delmarva coast on the night of the 15th and moved into the Gulf of Maine on the 16th. This brought steady precipitation to much of Vermont during the 15th into the 16th. Initially, the atmosphere was too mild for snow, but as the upper low moved closer to VT and the coastal low became the predominate system, colder air eventually worked from higher to lower elevations, especially in southern and eastern VT.
Snowfall amounts across central and eastern VT were generally 1 to 3 inches in the deeper valleys, 3 to 6 inches between 800-1500 feet and 6 to 10 inches above 1500 feet.
Impacts were marginal, other than some travel issues on roads above 1200-1500 feet.
