Soil conditions were nearly saturated across northern Iowa from the snow melt of the previous month. An elevated convection event took place with thunderstorms producing hail and heavy rainfall. Much of the rain that fell ran off, resulting in some minor flooding along the upper reaches of rivers in northern Iowa. Flooding was relatively minor and restricted to agricultural land.
