1998: Unseasonably warm weather brought the temperature up into the 50s and 60s across most of Iowa and into the lower 70s at nearly every station southeast of a line from Albia to Anamosa. The highest temperature of 73 F, only one degree shy of the all-time state December record, was reported at Burlington and Keosauqua.

1973: A winter storm on December 4-5 brought rain, ice, and snow to nearly all of Iowa except the far northwest. In many areas the effects of the storm were significant to severe with ice and snow making travel impossible, closing schools for days, bringing down power lines, and toppling radio towers in Hamilton and Hardin counties. Ice impacts were particularly severe in southwestern Iowa while further north and east storm total snowfall amounts ranged up to 7.0 inches at Decorah and Mason City, 7.5 inches at Britt and Rockwell City, 8.0 inches at Fayette, and 10.2 inches at Forest City.
