Episode Narrative A low pressure system moved across the southern U.S. during the overnight hours of the 23rd into the 24th. A strong inverted trough of low pressure traversed Iowa during this time. At the same time, an upper level system dropped southeast out of Canada into the central U.S. Snow developed during the evening hours of the 23rd. A band of heavier snow set up over north central into northeast Iowa. Though the snow did not come down at an extremely rapid rate, the snow fell for an extended period of time. A band of 7 to 11 inches of snow fell from Winnebago County, southeast into Black Hawk County. Some of the heavier snowfall totals included 11 inches in Clear Lake and 9.5 inches in Mason City, both in Cerro Gordo County. In Black Hawk County, 10.5 inches fell in Waterloo. Ten inches of snow fell in Winnebago County at Lake Mills and in Hancock County at Garner. Nine inches fell in Bremer County at Readlyn, with 8 inches falling in Butler County southeast of Dumont. The snow caused some travel problems with several accidents reported. A few roads were closed from time to time. Highway 65 east of Interstate 35 was closed for a while during the afternoon. Interstate 80 was closed for a couple hours in the Newton area due to accidents. Accidents also caused the closure of U.S. Highway 18 east of Emmetsburg. South and west of the heavy snow band, the rest of the DMX CWA received anywhere from 2 to 7 inches of snow.
