What about the flip side? Montana is home to both the greatest increase and decrease in temperature in the United States' record books. On Dec. 14, 1924, the temperature at Fairfield, Montana dropped from 63 degrees at noon to -21 at midnight from a strong arctic front. That 84 degree spread stands as the record 12-hour temperature drop.
Not to be outdone, Browning, MT holds the record for 24-hour drop. On Jan. 23, 1916, it went from 44 to -56 within a day -- a 100 degree drop. Talk about scrambling to find the heavy coat!
