Snowfall Reports

On the heals of the December 19th snowstorm, the region was hit with another heavy snowfall. A low pressure system organizing over the Mississippi Valley Saturday, December 20th, moved northeast to the Ohio Valley Saturday night. On Sunday, December 21st, a secondary area of low pressure developed along the mid Atlantic coast. This low became the primary low (nor' easter) as it rapidly deepened as it headed northeast along the New England coast.

Snow overspread the region early Sunday morning and was heavy at times with snowfall rates of 1 to 2 inches an hour during the day. Overall, the steady snow tapered off Sunday evening, however lake enhanced snow showers developed across the southern Adirondacks helping boost the snow accumulation. Total snowfall accumulations ranged from less than 4 inches across portions of the mid Hudson Valley and southern Litchfield County Connecticut to around a foot across portions of the western Adirondacks.

Strong and gusty east to southeast winds in advance of the low and west to northwest on the backside of the low caused blowing and drifting of snow.
