On January 25th, 1916 residents of Browning, Montana were still adjusting to the largest 24 hour temperature change on record in the U.S.. On January 23rd and 24th, 1916 the temperature fell from a pleasant 44 degrees above zero to a bitter -56 degrees in 24 hours. That's a temperature change of an amazing 100 degrees in 24 hours and that's a record that still stands as the largest 24 hour temperature fluctuation in the U.S. (Source: NOAA's National Weather Service Weather Forecast Office)
