According to the NWS, snow will occur across southwestern Lewis County, especially across the Tug Hill plateau late Wednesday through Thursday morning. Snow accumulations will range from 8 to 14 inches through Thursday.

The bands of snow are expected to then shift to far northern Lewis County Thursday night into Friday night. Expected snow accumulations over far northern Lewis County Thursday night through Friday night will range from 8 to 16 inches. Winds gusting as high as 35 mph will produce patchy blowing snow.
