The episode as NWS BTV wrote it up.
An upper atmospheric area of low pressure and weak surface low moved across northern New York on the morning of December 28th. Periods of light snow occurred from the pre-dawn through the early afternoon hours on December 28th which resulted in 1 to 3 inches of snow accumulation.
An arctic cold front and upper atmospheric disturbance moved across northern New York during the early morning hours of December 29th with snow showers and localized snow squalls. Widespread snowfall accumulations of 1 to 2 inches occurred with localized amounts up to 4 inches.
Two-day storm totals were 3 to 7 inches across much of northern New York.
Rapidly falling temperatures to near zero degrees along with falling and blowing snow before and during the morning commute of December 29th accounted for roads to flash freeze that resulted in numerous vehicle accidents.
