Summary
At approximately 4:57 PM, the tornado was first reported 1 mile southwest of Oelwein. The warning sirens sounded for only 15 seconds before power failed. After touching don, the tornado began to move in a linear line, tracking northeastward. Shortly after touching down, it entered the business area of Oelwein, hitting North Frederick Street and South Frederick Street. It also tracked through another block, located on Southeast First Avenue. 68 homes were destroyed here or in the surrounding area, and up to 132 homes were heavily damaged, while ~600 homes sustained relatively minor damage. Every business-owned building in downtown Oelwein sustained varying degrees of damage, and 51 were completely destroyed. Two churches, an elementary school, and the middle school were destroyed.

At around this point in the tornado's lifetime, multiple people reported seeing more than one tornado on the ground, although this has never been confirmed. The tornado then began to curve north, tracking through the western part of Maynard. ~25 houses were destroyed, and around 5 square blocks were destroyed at a high intensity, including a $120,000 (1968 USD) Lutheran church.

Many sparsely-distanced farms within a mile radius of the tornado path north of Maynard were either destroyed or heavily damaged, and many others received minor damage. The tornado curved upward at around this point, tracking due-north before lifting after ~5 miles.
