This EF2 tornado ran 5.8 miles across Greene County on October 11, 2021, touching down at 2:37 PM CDT and reaching 75 yards wide. It killed nobody, and did $100,000 of property damage.
The rating scale
Tracks are drawn in the color of the rating. The Enhanced Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.
EF065 to 85 mph
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
EF186 to 110 mph
Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.
EF2111 to 135 mphthis tornado
Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.
EF3136 to 165 mph
Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.
EF4166 to 200 mph
Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.
EF5over 200 mph
Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.
Unrated
The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

What the Weather Service recorded
On Monday, October 11th 2021 (Columbus Day), the potential for severe weather existed across east-central/northeast Missouri and most of central and northern Illinois. Despite limited instability (energy for storms to develop), plentiful shear (changing wind speed or direction with height) from a potent mid-level storm system provided the potential for severe storms. Though most storms never became strong or severe, one supercell in particular became organized enough to produce a tornado.
High resolution satellite data and information from storm spotters indicates the tornado touched down in an open field a little less than a mile south-southwest of the Berdan Road and Wrights Road intersection. The tornado moved north-northeast and intensified as it moved into the west side of the town of Wrights, IL. In Wrights, the tornado destroyed two new, well-built farm buildings, ripping one of from a concrete foundation around the perimeter of the building. The tornado then moved to the northeast, destroying two more farm buildings before crossing Wrights road, where it snapped a number of trees and rolled a camper onto a boat. The tornado continued to the northeast causing intermittent damage to trees and vegetation. The high resolution satellite data showed a prominent track in the open fields northeast of the NE 850 Ave and Super Slab Road Intersection. The last identifiable damage and where the tornado appeared to have ended is around a third of a mile west of the NE 1000 Street and NE 950 Ave Intersection. The tornado was rated EF2 with max wind speed of 115 mph. The path length was 5.83 miles with a max path width of 75 yards. No deaths or injuries were reported.

The warnings
No tornado warning for this county appears in the archive as in force at the moment the tornado touched down. One was issued for the county at another hour that day.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.
The forecast that day
The Storm Prediction Center had this point in a Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 16:19 UTC.

What this means
Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
