Wider weather episode

A long tracked and powerful winter storm, with a history from the Mississippi River valley through the southeast and north along the Appalachians into the northeast, impacted NY on January 17th. Snow moved into northern NY around midnight of January 17th with snowfall rates of 1-2 inches per hour at times during the morning, eventually ending by early afternoon with residual snow showers during the evening and night.

The complexity of the storm due to its strength and strong low level jet accounted for mesoscale features of snowfall distribution with east-side upslope regions witnessing higher totals and west-side downwind communities witnessing less snowfall.

General snowfall accumulations in northern NY were 6 to 12 inches with some locally higher amounts in the St. Lawrence River valley.
