National Oceanic and Atmospheric Administration

1991: Unusually early bitter cold temperatures settled across Iowa bringing the temperature below zero across nearly the entire state, with only far eastern and southeastern sections recording lows in the single digits above zero. Many stations set daily record lows and at numerous locations this is the earliest date on record on which the temperature has fallen below zero, including at Des Moines where the low was -3 F. The lowest reported temperatures in Iowa that morning included -12 F at Audubon, -13 F at Perry, -14 F at Le Mars, -15 F at Sheldon, -16 F at Guthrie Center, -17 F at Cherokee, and -19 F at Hawarden.
