Snow started falling across northeast Iowa during the morning of the 20th and continued into the evening hours before ending. Once the snow ended, it was replaced by freezing drizzle which created a light coating of glaze on the fresh snow and exposed surfaces. The snow resulted in several car accidents, but no injuries were reported from the accidents. Snowfall totals generally ranged from 4 to 5 inches with ice accumulations around an eighth of an inch. The highest reported snow totals were 7 inches at Waukon and 6.9 inches at Postville (Allamakee County).
