2009: An unusually cold autumn storm system brought snow to parts of western, northern, and central Iowa. A band of moderate snow developed during the morning hours stretching from around the Omaha metro area eastward to the Des Moines metro, roughly parallel to and just south of Interstate 80. Within this band several locations received an inch or more of snowfall including 3.0 inches at Atlantic and an amazing 6.7 inches at Underwood in Pottawattamie County. This is the second-highest snowfall amount on record in Iowa for so early in the season, bested only by the 9.0 inches recorded at Hawarden on October 9, 1970. At the Des Moines airport 1.1 inches of snow was recorded which tied the earliest date on record of measurable snow at that location and broke their record for the earliest snow of an inch or more. The snow melted very quickly at all affected locations.
