The Great Blue Norther of 11-11-11 (Fact 3)

The Great BlueNorther of 11 November 1911 was a cold front that affected the central United States. Many cities had record high temperatures in the early afternoon and record dropping temperatures by nightfall. This was the only day that many cities in the Midwest were able to break record highs and lows for the same day.

Cities such as Springfield, Missouri recorded a high of 80°F (27°C) before the cold front, 40°F (4°C) by nightfall and a record low of 13°F (-11°C) by midnight. The main cause for the dramatic cold snap was an extremely strong storm system that separated the warm, humid air from the frigid, arctic air.
