On November 11, 1911, the Midwest region of the United States experienced one of the weirdest weather days in American history when it was hit by the cold wave “The Great Blue Norther.”
Many cities went through the process of recording their record high temperature for the date only to record their record low for the date later that same day! Some of those cities and towns even suffered tornadoes and blizzards.
Examples of this bizarre temperature fluctuations include: Kansas City, Missouri which had its record high of 76 degrees F in the late morning and a low of 11 degrees F before midnight; Springfield, Missouri which went from its record high 80 degrees F to its record low of 13 degrees F; and Oklahoma City, Oklahoma which went from its record high of 83 degrees F to its record low of 17 degrees F. For the Celsius people out there, we are talking about average high temperatures of approx. 27 degrees C followed by average low temperatures of approx. -10 degrees C on the same day!
The next time one of your friends or family members tells you that the “weather is crazy nowadays,” you can remind them that on November 11, 1911, it was even crazier! And the date is easy to remember, 11-11-11.
