30 | 100 | 0 | 3 | F2 |
| Starting near the Dodge-Steele County line, this tornado skipped southeast hitting southeast of Hayfield. Barns were destroyed near the starting and ending points. Damage in the southeast part of Hayfield totalled $75,000 as at least a dozen homes were unroofed and many smaller buildings were destroyed. Losses outside Hayfield totalled $8,000. | ||||||||||
| 8 | 21 | 1883 | 1730 CST | Hayfield 4NW to Rochester | Olmsted | 25 | 1500 | 37 | 200 | F5 |
| The tornado moved east northeast from 4 miles northwest of Hayfield passing through and devastating Rochester. At least 10 of the 40 farms hits in Dodge County were leveled and at least 5 people were killed. The enormous roar was said to have warned most Rochester residents as the massive tornado cut through the north side of town. Over 135 homes were destroyed and another 200 damaged. Many of the injuries were very serious and other deaths probably occurred, but are not listed in the total. The tornado derailed a train causing many injuries. At least one crew member was killed. This tornado was a large factor in the subsequent development of the Mayo Clinic in Rochester. Total damage was estimated ay $700,000. | ||||||||||

| It moved east northeast from 4 miles southeast of Dodge Center to just south of Kasson and passing 1 mile north of Byron. The tornado turned to the north and dissipated after passing southeast of Douglas. About 20 homes, 30 barns, and three schools were damaged or destroyed. Three people were killed as two of "the finest homes in the county" were leveled in Dodge County. A half dozen farms "not a wall left standing." The damage may have been from two parallel tracks. This event was either a family of tornadoes on parallel tracks eight miles apart. Resolving the time and position conflicts is probably not possible. | ||||||||||
