On January 22, 1943, a sudden weather change in Spearfish, South Dakota set a record that still holds to this day. At 7:30 A.M., the temperature in Spearfish was four degrees below zero.

A Chinook wind picked up speed, and in two minutes, 7:32 A.M., the temperature rose to 45 degrees above zero. By 9 A.M., it had risen to 54 degrees.

Just as suddenly, the Chinook died out, and the temperature tumbled back to four degrees below zero. The 58 degree drop took only 27 minutes.
