A very large arctic high built southward from eastern Canada early on January 17. At the same, deep low pressure system settled in over the Canadian Maritimes. A strong pressure gradient developed between these two features resulting a northwest wind averaging between 15 and 30 miles an hour across the Berkshires. At the same time, temperatures plummeted to between zero and 10 below. The combination of the very low temperatures and the strong wind, produced dangerously low wind chill values in the 50 to 60 below zero range. The dangerous wind chills persisted well into the midday hours despite bright sunshine.
