From Milmine to Monticello, this F1 tornado ran 2.0 miles across Piatt County on April 19, 1996, touching down at 8:00 PM CDT and reaching 300 yards wide. It killed nobody and injured 1, and did $1.0 million of property damage.
The rating scale
Tracks are drawn in the color of the rating. The Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.
F040 to 72 mph
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
F173 to 112 mphthis tornado
Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.
F2113 to 157 mph
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.
F3158 to 206 mph
Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.
F4207 to 260 mph
Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.
F5261 to 318 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
A tornado briefly touched down in Milmine completely destroying a new grain bin, throwing a grain auger across the railroad tracks, and caused minor damage to some homes in town, mainly some shingle and window damage. Also, several trees were blown down, windows on a number of cars were broken and several large trucks were overturned. No injuries were reported and damage was estimated around $500,000.
A tornado touched down briefly 3 miles south of Monticello, in the Breezy Meadows subdivision where it destroyed 2 homes, seriously damaged a third, caused major damage to a church and a metal machine shed. The tornado then lifted and travelled to the northeast touching down 2 miles southeast of Monticello at the Monticello Airport. Again, the tornado was only on the ground briefly, destroying 3 single engine planes, 2 gliders, a hanger and caused major damage to another hanger before lifting and dissipating. Only one minor injury was reported and damage was estimated around $1 million.
From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.
The warnings
18 minutes of warning. NWS ILX issued a tornado warning for this county at 00:42 UTC, 18 minutes before the tornado touched down, in force until 01:15 UTC.

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 Moderate Risk. The outlook in force was issued at 06:07 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.
