Wider weather episode

An arctic airmass moved into northern New York during the night of the 17th and delivered colder air through the 18th. Meanwhile, a strong pressure gradient between the arctic high across the Great Lakes and the departing storm in Newfoundland was creating brisk winds of 10 to 20 mph with higher gusts. The combination resulted in wind chills of 15 to 25 below zero in the Adirondacks and St. Lawrence Valley.
