The 100th Anniversary of the Cold Front of 11/11/11

Below is the annotated record from the Weather Bureau’s Springfield, MO thermograph from November 11, 1911:

The temperature reached a high of 80° then dropped 40° almost instantly and continued to drop until it reached 13° at midnight. In many Midwest and Plains cities, the record high and low on November 11th both occurred on the same day one hundred years ago.

Impacts from this amazing cold front included a reported 9 tornadoes in Michigan, Illinois, Indiana, and Wisconsin, widespread dust storms in Oklahoma, extensive thunderstorms with straight line wind damage; all followed by near blizzard conditions behind the front.
