- Injuries and deaths are for the tornado’s whole path, which may extend beyond this area.
- Weak tornadoes were under-recorded before Doppler radar coverage became national in the early 1990s, so earlier decades read low. Ratings use the Fujita scale before February 2007 and the Enhanced Fujita scale after.

- A smoke day is a date on which a smoke plume traced by NOAA Hazard Mapping System analysts from satellite imagery covered this place's point (the county's population centre or the city centre). Counts here are of medium or heavy smoke. Since 2018 analysts have often drawn light smoke as one area over most of the continent, so light-smoke counts are not comparable from year to year. The plumes show smoke anywhere in the air above, not air quality at the ground, and smoke hidden by cloud is missed.

National Weather Service narrative
Heavy rainfall from September 10-12 totalling 7 to 8 inches near Mitchell led to widespread areal flooding. Travel was significantly hampered across most of the county, including the closure of Interstate 90. Smaller creeks and ponding resulted in the closure of most township and county roads. Five miles south of Mitchell, a bridge over Enemy Creek was washed out, requiring a swift water rescue of one person who was overwhelmed by the current. Three residents located one-half mile east of this bridge were also evacuated from waist deep waters. This bridge was one of nine damaged across the county. A no-wake order was placed on Lake Mitchell due to extremely high water. Significant…

National Weather Service narrative
Heavy freezing rain coated roads, trees, power lines, and most other objects with ice up to 3 inches thick. Travel quickly became difficult to impossible. Many roads including Interstate Highways 90 and 29 were closed for extended periods of time. Most schools and businesses were forced to close. Electric power was lost over widespread areas when many miles of power lines and thousands of poles were knocked down, with more damaged. Strong winds which accompanied the ice storm and the immediately following blizzard combined with the weight of the ice to bring down many of the power lines and poles. Tens of thousands of households and businesses lost power, with the time power was…
