A strong fall storm system affected much of the Northland on November 11 into the 12th. Warm temperatures ahead of an area of low pressure led to a rain event across the southern part of the area while colder air moving in from the north led to a changeover to snow from the International Falls area southward into the Iron Range area earlier than forecast. This lead to snowfall of 6 to 8 inches from southern Koochiching County into central St. Louis County where a colder pocket of air moved in and kept snow going earlier and longer than anticipated. The snow along the Iron Range led to snow and ice covered roads and multiple wrecks. One wreck near Gilbert resulted in two fatalities.

An arctic airmass was centered over the northern Plains, and Kentucky and southern Indiana were positioned directly along a volatile boundary between the arctic air mass and a warm and moist tropical airmass associated with the Gulf of Mexico. The vertical temperature profile was ideal for the formation of freezing rain. The arctic air wedged itself beneath a warm and moist layer aloft. As energy associated with the jet stream passed over the Ohio Valley, a mix of wintry precipitation occurred. A large swath of freezing rain occurred, stretching mainly west to east across Kentucky. To the north, a small area of sleet occurred in around Louisville and into southern Indiana.
