The Great Blue Norther of 11/11/11 (November 11th 1911) was the biggest cold snap in U.S. history. Many cities broke record highs early that afternoon. By nightfall, cities were dealing with single-digit temperatures on the Fahrenheit scale. This is the only day in many midwest cities' weather bureau jurisdictions where the record highs and lows were broken for the same day.
