The episode as NWS OAX wrote it up.
An upper level disturbance tracking across the plains caused low pressure to deepen as it tracked from northern Oklahoma into northeast Missouri. Snow, occasionally moderate and even briefly heavy, fell from late on the 29th into the morning hours of the 30th. Snow amounts in southwest Iowa were generally 3 to 6 inches, with around 6 inches reported from Glenwood through Shenandoah, Iowa. The snow was accompanied by north winds of 20 to 35 which caused considerable blowing and drifting snow and several hours of poor visibilities.
