1925: The first of two successive snowfalls affected nearly all of Iowa on October 25-26 producing accumulations as high as 6.0 inches at Denison, Le Mars, and Onawa, 7.0 inches at Boone, Guthrie Center, and Storm Lake, 7.1 inches at New Hampton, 7.3 inches at Marshalltown, and 7.5 inches at Rockwell City. Even in southeastern Iowa 3.5 inches fell at Keosauqua and 3.2 inches at Keokuk. Another snow storm would affect the southern half of Iowa just a couple of days later.
1898: A winter storm affected most of Iowa with the most significant effects being felt in the east. At Clinton precipitation began as rain then changed to snow at about noon with winds becoming strong from the northeast. The snow fell very heavily but much of it melted as it came down due to surface temperatures remaining above freezing, otherwise accumulations would have been considerably higher. By evening temperatures had fallen below the freezing point allowing more snow to accumulate and the water on all exposed surfaces to freeze. As a result of the ice and heavy wet snow many trees and utility poles and wires were downed across the area. Very low visibilities and blizzard conditions were observed at Albia, Amana, Clinton, and Wapello where 3.0 inches of snow was measured. Other reported snowfall amounts included 2.0 inches at Keosauqua, 4.0 inches at Amana, and 6.0 inches at Olin and Ovid.
